SOLD Panthère Secrete Ladies 27mm RG 8848F 1:1 Best Edition White Dial on Black Croco Strap Ronda Quartz

I was super keen to try see the quality from intime as they have a great reputation on RepTime. This is a great watch, however I feel like it doesn’t suit my style and I still prefer my auth Rolex Ladyjust 28mm :-D. So I am selling this! It’s brand new and I haven’t even tried it on, as I just felt that I wouldn’t use it when I first got it. It still has all of the stickers on the watch.

** SOLD Valentino Caged Rockstud Flats Noir sz 39** Will fit a small 39 / 38.5.

I am just so sad that these don’t fit me! After I had my baby my feet are just a tad too big for 39’s and I am a bit devastated as these are a pair of dream shoes. I will be placing an order for another pair in sz 40 once these are sold, as I love the colorway and quality!

SOLD Gucci Ace Dog sneakers sz 39 Will fit a small 39 /38.5

Another pair I am just so sad I can’t fit properly! I will be repurchasing these in a sz 40 as well. I just love that they have dogs on them, and I fell in love when my friend was wearing the auth last year and just had to have them… but then of course, it was a 2018 collection and couldn’t find them.

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Great Reddit Scaling Bake-Off Public Proposal

Dragonchain Public Proposal TL;DR:

Dragonchain has demonstrated twice Reddit’s entire total daily volume (votes, comments, and posts per Reddit 2019 Year in Review) in a 24-hour demo on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. At the time, in January 2020, the entire cost of the demo was approximately $25K on a single system (transaction fees locked at $0.0001/txn). With current fees (lowest fee $0.0000025/txn), this would cost as little as $625.
Watch Joe walk through the entire proposal and answer questions on YouTube.
This proposal is also available on the Dragonchain blog.

Hello Reddit and Ethereum community!

I’m Joe Roets, Founder & CEO of Dragonchain. When the team and I first heard about The Great Reddit Scaling Bake-Off we were intrigued. We believe we have the solutions Reddit seeks for its community points system and we have them at scale.
For your consideration, we have submitted our proposal below. The team at Dragonchain and I welcome and look forward to your technical questions, philosophical feedback, and fair criticism, to build a scaling solution for Reddit that will empower its users. Because our architecture is unlike other blockchain platforms out there today, we expect to receive many questions while people try to grasp our project. I will answer all questions here in this thread on Reddit, and I've answered some questions in the stream on YouTube.
We have seen good discussions so far in the competition. We hope that Reddit’s scaling solution will emerge from The Great Reddit Scaling Bake-Off and that Reddit will have great success with the implementation.

Executive summary

Dragonchain is a robust open source hybrid blockchain platform that has proven to withstand the passing of time since our inception in 2014. We have continued to evolve to harness the scalability of private nodes, yet take full advantage of the security of public decentralized networks, like Ethereum. We have a live, operational, and fully functional Interchain network integrating Bitcoin, Ethereum, Ethereum Classic, and ~700 independent Dragonchain nodes. Every transaction is secured to Ethereum, Bitcoin, and Ethereum Classic. Transactions are immediately usable on chain, and the first decentralization is seen within 20 seconds on Dragon Net. Security increases further to public networks ETH, BTC, and ETC within 10 minutes to 2 hours. Smart contracts can be written in any executable language, offering full freedom to existing developers. We invite any developer to watch the demo, play with our SDK’s, review open source code, and to help us move forward. Dragonchain specializes in scalable loyalty & rewards solutions and has built a decentralized social network on chain, with very affordable transaction costs. This experience can be combined with the insights Reddit and the Ethereum community have gained in the past couple of months to roll out the solution at a rapid pace.

Response and PoC

In The Great Reddit Scaling Bake-Off post, Reddit has asked for a series of demonstrations, requirements, and other considerations. In this section, we will attempt to answer all of these requests.

Live Demo

A live proof of concept showing hundreds of thousands of transactions
On Jan 7, 2020, Dragonchain hosted a 24-hour live demonstration during which a quarter of a billion (250 million+) transactions executed fully on an operational network. Every single transaction on Dragonchain is decentralized immediately through 5 levels of Dragon Net, and then secured with combined proof on Bitcoin, Ethereum, Ethereum Classic, and Binance Chain, via Interchain. This means that every single transaction is secured by, and traceable to these networks. An attack on this system would require a simultaneous attack on all of the Interchained networks.
24 hours in 4 minutes (YouTube):
24 hours in 4 minutes
The demonstration was of a single business system, and any user is able to scale this further, by running multiple systems simultaneously. Our goals for the event were to demonstrate a consistent capacity greater than that of Visa over an extended time period.
Tooling to reproduce our demo is available here:
https://github.com/dragonchain/spirit-bomb

Source Code

Source code (for on & off-chain components as well tooling used for the PoC). The source code does not have to be shared publicly, but if Reddit decides to use a particular solution it will need to be shared with Reddit at some point.

Scaling

How it works & scales

Architectural Scaling

Dragonchain’s architecture attacks the scalability issue from multiple angles. Dragonchain is a hybrid blockchain platform, wherein every transaction is protected on a business node to the requirements of that business or purpose. A business node may be held completely private or may be exposed or replicated to any level of exposure desired.
Every node has its own blockchain and is independently scalable. Dragonchain established Context Based Verification as its consensus model. Every transaction is immediately usable on a trust basis, and in time is provable to an increasing level of decentralized consensus. A transaction will have a level of decentralization to independently owned and deployed Dragonchain nodes (~700 nodes) within seconds, and full decentralization to BTC and ETH within minutes or hours. Level 5 nodes (Interchain nodes) function to secure all transactions to public or otherwise external chains such as Bitcoin and Ethereum. These nodes scale the system by aggregating multiple blocks into a single Interchain transaction on a cadence. This timing is configurable based upon average fees for each respective chain. For detailed information about Dragonchain’s architecture, and Context Based Verification, please refer to the Dragonchain Architecture Document.

Economic Scaling

An interesting feature of Dragonchain’s network consensus is its economics and scarcity model. Since Dragon Net nodes (L2-L4) are independent staking nodes, deployment to cloud platforms would allow any of these nodes to scale to take on a large percentage of the verification work. This is great for scalability, but not good for the economy, because there is no scarcity, and pricing would develop a downward spiral and result in fewer verification nodes. For this reason, Dragonchain uses TIME as scarcity.
TIME is calculated as the number of Dragons held, multiplied by the number of days held. TIME influences the user’s access to features within the Dragonchain ecosystem. It takes into account both the Dragon balance and length of time each Dragon is held. TIME is staked by users against every verification node and dictates how much of the transaction fees are awarded to each participating node for every block.
TIME also dictates the transaction fee itself for the business node. TIME is staked against a business node to set a deterministic transaction fee level (see transaction fee table below in Cost section). This is very interesting in a discussion about scaling because it guarantees independence for business implementation. No matter how much traffic appears on the entire network, a business is guaranteed to not see an increased transaction fee rate.

Scaled Deployment

Dragonchain uses Docker and Kubernetes to allow the use of best practices traditional system scaling. Dragonchain offers managed nodes with an easy to use web based console interface. The user may also deploy a Dragonchain node within their own datacenter or favorite cloud platform. Users have deployed Dragonchain nodes on-prem on Amazon AWS, Google Cloud, MS Azure, and other hosting platforms around the world. Any executable code, anything you can write, can be written into a smart contract. This flexibility is what allows us to say that developers with no blockchain experience can use any code language to access the benefits of blockchain. Customers have used NodeJS, Python, Java, and even BASH shell script to write smart contracts on Dragonchain.
With Docker containers, we achieve better separation of concerns, faster deployment, higher reliability, and lower response times.
We chose Kubernetes for its self-healing features, ability to run multiple services on one server, and its large and thriving development community. It is resilient, scalable, and automated. OpenFaaS allows us to package smart contracts as Docker images for easy deployment.
Contract deployment time is now bounded only by the size of the Docker image being deployed but remains fast even for reasonably large images. We also take advantage of Docker’s flexibility and its ability to support any language that can run on x86 architecture. Any image, public or private, can be run as a smart contract using Dragonchain.

Flexibility in Scaling

Dragonchain’s architecture considers interoperability and integration as key features. From inception, we had a goal to increase adoption via integration with real business use cases and traditional systems.
We envision the ability for Reddit, in the future, to be able to integrate alternate content storage platforms or other financial services along with the token.
  • LBRY - To allow users to deploy content natively to LBRY
  • MakerDAO to allow users to lend small amounts backed by their Reddit community points.
  • STORJ/SIA to allow decentralized on chain storage of portions of content. These integrations or any other are relatively easy to integrate on Dragonchain with an Interchain implementation.

Cost

Cost estimates (on-chain and off-chain) For the purpose of this proposal, we assume that all transactions are on chain (posts, replies, and votes).
On the Dragonchain network, transaction costs are deterministic/predictable. By staking TIME on the business node (as described above) Reddit can reduce transaction costs to as low as $0.0000025 per transaction.
Dragonchain Fees Table

Getting Started

How to run it
Building on Dragonchain is simple and requires no blockchain experience. Spin up a business node (L1) in our managed environment (AWS), run it in your own cloud environment, or on-prem in your own datacenter. Clear documentation will walk you through the steps of spinning up your first Dragonchain Level 1 Business node.
Getting started is easy...
  1. Download Dragonchain’s dctl
  2. Input three commands into a terminal
  3. Build an image
  4. Run it
More information can be found in our Get started documents.

Architecture
Dragonchain is an open source hybrid platform. Through Dragon Net, each chain combines the power of a public blockchain (like Ethereum) with the privacy of a private blockchain.
Dragonchain organizes its network into five separate levels. A Level 1, or business node, is a totally private blockchain only accessible through the use of public/private keypairs. All business logic, including smart contracts, can be executed on this node directly and added to the chain.
After creating a block, the Level 1 business node broadcasts a version stripped of sensitive private data to Dragon Net. Three Level 2 Validating nodes validate the transaction based on guidelines determined from the business. A Level 3 Diversity node checks that the level 2 nodes are from a diverse array of locations. A Level 4 Notary node, hosted by a KYC partner, then signs the validation record received from the Level 3 node. The transaction hash is ledgered to the Level 5 public chain to take advantage of the hash power of massive public networks.
Dragon Net can be thought of as a “blockchain of blockchains”, where every level is a complete private blockchain. Because an L1 can send to multiple nodes on a single level, proof of existence is distributed among many places in the network. Eventually, proof of existence reaches level 5 and is published on a public network.

API Documentation

APIs (on chain & off)

SDK Source

Nobody’s Perfect

Known issues or tradeoffs
  • Dragonchain is open source and even though the platform is easy enough for developers to code in any language they are comfortable with, we do not have so large a developer community as Ethereum. We would like to see the Ethereum developer community (and any other communities) become familiar with our SDK’s, our solutions, and our platform, to unlock the full potential of our Ethereum Interchain. Long ago we decided to prioritize both Bitcoin and Ethereum Interchains. We envision an ecosystem that encompasses different projects to give developers the ability to take full advantage of all the opportunities blockchain offers to create decentralized solutions not only for Reddit but for all of our current platforms and systems. We believe that together we will take the adoption of blockchain further. We currently have additional Interchain with Ethereum Classic. We look forward to Interchain with other blockchains in the future. We invite all blockchains projects who believe in decentralization and security to Interchain with Dragonchain.
  • While we only have 700 nodes compared to 8,000 Ethereum and 10,000 Bitcoin nodes. We harness those 18,000 nodes to scale to extremely high levels of security. See Dragonchain metrics.
  • Some may consider the centralization of Dragonchain’s business nodes as an issue at first glance, however, the model is by design to protect business data. We do not consider this a drawback as these nodes can make any, none, or all data public. Depending upon the implementation, every subreddit could have control of its own business node, for potential business and enterprise offerings, bringing new alternative revenue streams to Reddit.

Costs and resources

Summary of cost & resource information for both on-chain & off-chain components used in the PoC, as well as cost & resource estimates for further scaling. If your PoC is not on mainnet, make note of any mainnet caveats (such as congestion issues).
Every transaction on the PoC system had a transaction fee of $0.0001 (one-hundredth of a cent USD). At 256MM transactions, the demo cost $25,600. With current operational fees, the same demonstration would cost $640 USD.
For the demonstration, to achieve throughput to mimic a worldwide payments network, we modeled several clients in AWS and 4-5 business nodes to handle the traffic. The business nodes were tuned to handle higher throughput by adjusting memory and machine footprint on AWS. This flexibility is valuable to implementing a system such as envisioned by Reddit. Given that Reddit’s daily traffic (posts, replies, and votes) is less than half that of our demo, we would expect that the entire Reddit system could be handled on 2-5 business nodes using right-sized containers on AWS or similar environments.
Verification was accomplished on the operational Dragon Net network with over 700 independently owned verification nodes running around the world at no cost to the business other than paid transaction fees.

Requirements

Scaling

This PoC should scale to the numbers below with minimal costs (both on & off-chain). There should also be a clear path to supporting hundreds of millions of users.
Over a 5 day period, your scaling PoC should be able to handle:
*100,000 point claims (minting & distributing points) *25,000 subscriptions *75,000 one-off points burning *100,000 transfers
During Dragonchain’s 24 hour demo, the above required numbers were reached within the first few minutes.
Reddit’s total activity is 9000% more than Ethereum’s total transaction level. Even if you do not include votes, it is still 700% more than Ethereum’s current volume. Dragonchain has demonstrated that it can handle 250 million transactions a day, and it’s architecture allows for multiple systems to work at that level simultaneously. In our PoC, we demonstrate double the full capacity of Reddit, and every transaction was proven all the way to Bitcoin and Ethereum.
Reddit Scaling on Ethereum

Decentralization

Solutions should not depend on any single third-party provider. We prefer solutions that do not depend on specific entities such as Reddit or another provider, and solutions with no single point of control or failure in off-chain components but recognize there are numerous trade-offs to consider
Dragonchain’s architecture calls for a hybrid approach. Private business nodes hold the sensitive data while the validation and verification of transactions for the business are decentralized within seconds and secured to public blockchains within 10 minutes to 2 hours. Nodes could potentially be controlled by owners of individual subreddits for more organic decentralization.
  • Billing is currently centralized - there is a path to federation and decentralization of a scaled billing solution.
  • Operational multi-cloud
  • Operational on-premises capabilities
  • Operational deployment to any datacenter
  • Over 700 independent Community Verification Nodes with proof of ownership
  • Operational Interchain (Interoperable to Bitcoin, Ethereum, and Ethereum Classic, open to more)

Usability Scaling solutions should have a simple end user experience.

Users shouldn't have to maintain any extra state/proofs, regularly monitor activity, keep track of extra keys, or sign anything other than their normal transactions
Dragonchain and its customers have demonstrated extraordinary usability as a feature in many applications, where users do not need to know that the system is backed by a live blockchain. Lyceum is one of these examples, where the progress of academy courses is being tracked, and successful completion of courses is rewarded with certificates on chain. Our @Save_The_Tweet bot is popular on Twitter. When used with one of the following hashtags - #please, #blockchain, #ThankYou, or #eternalize the tweet is saved through Eternal to multiple blockchains. A proof report is available for future reference. Other examples in use are DEN, our decentralized social media platform, and our console, where users can track their node rewards, view their TIME, and operate a business node.
Examples:

Transactions complete in a reasonable amount of time (seconds or minutes, not hours or days)
All transactions are immediately usable on chain by the system. A transaction begins the path to decentralization at the conclusion of a 5-second block when it gets distributed across 5 separate community run nodes. Full decentralization occurs within 10 minutes to 2 hours depending on which interchain (Bitcoin, Ethereum, or Ethereum Classic) the transaction hits first. Within approximately 2 hours, the combined hash power of all interchained blockchains secures the transaction.

Free to use for end users (no gas fees, or fixed/minimal fees that Reddit can pay on their behalf)
With transaction pricing as low as $0.0000025 per transaction, it may be considered reasonable for Reddit to cover transaction fees for users.
All of Reddit's Transactions on Blockchain (month)
Community points can be earned by users and distributed directly to their Reddit account in batch (as per Reddit minting plan), and allow users to withdraw rewards to their Ethereum wallet whenever they wish. Withdrawal fees can be paid by either user or Reddit. This model has been operating inside the Dragonchain system since 2018, and many security and financial compliance features can be optionally added. We feel that this capability greatly enhances user experience because it is seamless to a regular user without cryptocurrency experience, yet flexible to a tech savvy user. With regard to currency or token transactions, these would occur on the Reddit network, verified to BTC and ETH. These transactions would incur the $0.0000025 transaction fee. To estimate this fee we use the monthly active Reddit users statista with a 60% adoption rate and an estimated 10 transactions per month average resulting in an approximate $720 cost across the system. Reddit could feasibly incur all associated internal network charges (mining/minting, transfer, burn) as these are very low and controllable fees.
Reddit Internal Token Transaction Fees

Reddit Ethereum Token Transaction Fees
When we consider further the Ethereum fees that might be incurred, we have a few choices for a solution.
  1. Offload all Ethereum transaction fees (user withdrawals) to interested users as they wish to withdraw tokens for external use or sale.
  2. Cover Ethereum transaction fees by aggregating them on a timed schedule. Users would request withdrawal (from Reddit or individual subreddits), and they would be transacted on the Ethereum network every hour (or some other schedule).
  3. In a combination of the above, customers could cover aggregated fees.
  4. Integrate with alternate Ethereum roll up solutions or other proposals to aggregate minting and distribution transactions onto Ethereum.

Bonus Points

Users should be able to view their balances & transactions via a blockchain explorer-style interface
From interfaces for users who have no knowledge of blockchain technology to users who are well versed in blockchain terms such as those present in a typical block explorer, a system powered by Dragonchain has flexibility on how to provide balances and transaction data to users. Transactions can be made viewable in an Eternal Proof Report, which displays raw data along with TIME staking information and traceability all the way to Bitcoin, Ethereum, and every other Interchained network. The report shows fields such as transaction ID, timestamp, block ID, multiple verifications, and Interchain proof. See example here.
Node payouts within the Dragonchain console are listed in chronological order and can be further seen in either Dragons or USD. See example here.
In our social media platform, Dragon Den, users can see, in real-time, their NRG and MTR balances. See example here.
A new influencer app powered by Dragonchain, Raiinmaker, breaks down data into a user friendly interface that shows coin portfolio, redeemed rewards, and social scores per campaign. See example here.

Exiting is fast & simple
Withdrawing funds on Dragonchain’s console requires three clicks, however, withdrawal scenarios with more enhanced security features per Reddit’s discretion are obtainable.

Interoperability Compatibility with third party apps (wallets/contracts/etc) is necessary.
Proven interoperability at scale that surpasses the required specifications. Our entire platform consists of interoperable blockchains connected to each other and traditional systems. APIs are well documented. Third party permissions are possible with a simple smart contract without the end user being aware. No need to learn any specialized proprietary language. Any code base (not subsets) is usable within a Docker container. Interoperable with any blockchain or traditional APIs. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js. Please see our source code and API documentation.

Scaling solutions should be extensible and allow third parties to build on top of it Open source and extensible
APIs should be well documented and stable

Documentation should be clear and complete
For full documentation, explore our docs, SDK’s, Github repo’s, architecture documents, original Disney documentation, and other links or resources provided in this proposal.

Third-party permissionless integrations should be possible & straightforward Smart contracts are Docker based, can be written in any language, use full language (not subsets), and can therefore be integrated with any system including traditional system APIs. Simple is better. Learning an uncommon or proprietary language should not be necessary.
Advanced knowledge of mathematics, cryptography, or L2 scaling should not be required. Compatibility with common utilities & toolchains is expected.
Dragonchain business nodes and smart contracts leverage Docker to allow the use of literally any language or executable code. No proprietary language is necessary. We’ve witnessed relatively complex systems built by engineers with no blockchain or cryptocurrency experience. We’ve also demonstrated the creation of smart contracts within minutes built with BASH shell and Node.js.

Bonus

Bonus Points: Show us how it works. Do you have an idea for a cool new use case for Community Points? Build it!

TIME

Community points could be awarded to Reddit users based upon TIME too, whereas the longer someone is part of a subreddit, the more community points someone naturally gained, even if not actively commenting or sharing new posts. A daily login could be required for these community points to be credited. This grants awards to readers too and incentivizes readers to create an account on Reddit if they browse the website often. This concept could also be leveraged to provide some level of reputation based upon duration and consistency of contribution to a community subreddit.

Dragon Den

Dragonchain has already built a social media platform that harnesses community involvement. Dragon Den is a decentralized community built on the Dragonchain blockchain platform. Dragon Den is Dragonchain’s answer to fake news, trolling, and censorship. It incentivizes the creation and evaluation of quality content within communities. It could be described as being a shareholder of a subreddit or Reddit in its entirety. The more your subreddit is thriving, the more rewarding it will be. Den is currently in a public beta and in active development, though the real token economy is not live yet. There are different tokens for various purposes. Two tokens are Lair Ownership Rights (LOR) and Lair Ownership Tokens (LOT). LOT is a non-fungible token for ownership of a specific Lair. LOT will only be created and converted from LOR.
Energy (NRG) and Matter (MTR) work jointly. Your MTR determines how much NRG you receive in a 24-hour period. Providing quality content, or evaluating content will earn MTR.

Security. Users have full ownership & control of their points.
All community points awarded based upon any type of activity or gift, are secured and provable to all Interchain networks (currently BTC, ETH, ETC). Users are free to spend and withdraw their points as they please, depending on the features Reddit wants to bring into production.

Balances and transactions cannot be forged, manipulated, or blocked by Reddit or anyone else
Users can withdraw their balance to their ERC20 wallet, directly through Reddit. Reddit can cover the fees on their behalf, or the user covers this with a portion of their balance.

Users should own their points and be able to get on-chain ERC20 tokens without permission from anyone else
Through our console users can withdraw their ERC20 rewards. This can be achieved on Reddit too. Here is a walkthrough of our console, though this does not show the quick withdrawal functionality, a user can withdraw at any time. https://www.youtube.com/watch?v=aNlTMxnfVHw

Points should be recoverable to on-chain ERC20 tokens even if all third-parties involved go offline
If necessary, signed transactions from the Reddit system (e.g. Reddit + Subreddit) can be sent to the Ethereum smart contract for minting.

A public, third-party review attesting to the soundness of the design should be available
To our knowledge, at least two large corporations, including a top 3 accounting firm, have conducted positive reviews. These reviews have never been made public, as Dragonchain did not pay or contract for these studies to be released.

Bonus points
Public, third-party implementation review available or in progress
See above

Compatibility with HSMs & hardware wallets
For the purpose of this proposal, all tokenization would be on the Ethereum network using standard token contracts and as such, would be able to leverage all hardware wallet and Ethereum ecosystem services.

Other Considerations

Minting/distributing tokens is not performed by Reddit directly
This operation can be automated by smart contract on Ethereum. Subreddits can if desired have a role to play.

One off point burning, as well as recurring, non-interactive point burning (for subreddit memberships) should be possible and scalable
This is possible and scalable with interaction between Dragonchain Reddit system and Ethereum token contract(s).

Fully open-source solutions are strongly preferred
Dragonchain is fully open source (see section on Disney release after conclusion).

Conclusion

Whether it is today, or in the future, we would like to work together to bring secure flexibility to the highest standards. It is our hope to be considered by Ethereum, Reddit, and other integrative solutions so we may further discuss the possibilities of implementation. In our public demonstration, 256 million transactions were handled in our operational network on chain in 24 hours, for the low cost of $25K, which if run today would cost $625. Dragonchain’s interoperable foundation provides the atmosphere necessary to implement a frictionless community points system. Thank you for your consideration of our proposal. We look forward to working with the community to make something great!

Disney Releases Blockchain Platform as Open Source

The team at Disney created the Disney Private Blockchain Platform. The system was a hybrid interoperable blockchain platform for ledgering and smart contract development geared toward solving problems with blockchain adoption and usability. All objective evaluation would consider the team’s output a success. We released a list of use cases that we explored in some capacity at Disney, and our input on blockchain standardization as part of our participation in the W3C Blockchain Community Group.
https://lists.w3.org/Archives/Public/public-blockchain/2016May/0052.html

Open Source

In 2016, Roets proposed to release the platform as open source to spread the technology outside of Disney, as others within the W3C group were interested in the solutions that had been created inside of Disney.
Following a long process, step by step, the team met requirements for release. Among the requirements, the team had to:
  • Obtain VP support and approval for the release
  • Verify ownership of the software to be released
  • Verify that no proprietary content would be released
  • Convince the organization that there was a value to the open source community
  • Convince the organization that there was a value to Disney
  • Offer the plan for ongoing maintenance of the project outside of Disney
  • Itemize competing projects
  • Verify no conflict of interest
  • Preferred license
  • Change the project name to not use the name Disney, any Disney character, or any other associated IP - proposed Dragonchain - approved
  • Obtain legal approval
  • Approval from corporate, parks, and other business units
  • Approval from multiple Disney patent groups Copyright holder defined by Disney (Disney Connected and Advanced Technologies)
  • Trademark searches conducted for the selected name Dragonchain
  • Obtain IT security approval
  • Manual review of OSS components conducted
  • OWASP Dependency and Vulnerability Check Conducted
  • Obtain technical (software) approval
  • Offer management, process, and financial plans for the maintenance of the project.
  • Meet list of items to be addressed before release
  • Remove all Disney project references and scripts
  • Create a public distribution list for email communications
  • Remove Roets’ direct and internal contact information
  • Create public Slack channel and move from Disney slack channels
  • Create proper labels for issue tracking
  • Rename internal private Github repository
  • Add informative description to Github page
  • Expand README.md with more specific information
  • Add information beyond current “Blockchains are Magic”
  • Add getting started sections and info on cloning/forking the project
  • Add installation details
  • Add uninstall process
  • Add unit, functional, and integration test information
  • Detail how to contribute and get involved
  • Describe the git workflow that the project will use
  • Move to public, non-Disney git repository (Github or Bitbucket)
  • Obtain Disney Open Source Committee approval for release
On top of meeting the above criteria, as part of the process, the maintainer of the project had to receive the codebase on their own personal email and create accounts for maintenance (e.g. Github) with non-Disney accounts. Given the fact that the project spanned multiple business units, Roets was individually responsible for its ongoing maintenance. Because of this, he proposed in the open source application to create a non-profit organization to hold the IP and maintain the project. This was approved by Disney.
The Disney Open Source Committee approved the application known as OSSRELEASE-10, and the code was released on October 2, 2016. Disney decided to not issue a press release.

Why i’m bullish on Zilliqa (long read)

Edit: TL;DR added in the comments
 
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
 
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction
 
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
 
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
 
Decentralisation
 
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. The faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time-stamped so you’ll start right away with a platform introduction, roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
 
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships
 
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!

Monero - The Elephant in the Room

The state of financial privacy in 2020
Note: You can read this in a friendlier format with images over on Medium - https://medium.com/@johnfoss/the-elephant-in-the-room-34e061f5912a
The erosion of personal privacy is gaining momentum since the coronavirus pandemic took hold. Worldwide, there have been numerous calls by governments and social commentators to increase the surveillance of citizens in hope of controlling the virus. Corporations such as Google and Apple, along with countries such as Singapore, Germany, Belgium, USA, and South Korea have been utilizing smartphone data in different capacities to monitor the movements of citizens.
Many believe the implementation of new surveillance measures will calcify and become the new norm, setting precedence for further encroachment.
Mainstream media has also begun supporting the notion of increased surveillance to serve social and financial needs. A recent Bloomberg opinion piece discussed the need for increased surveillance, pointing out the financial system we operate within is fractured and inefficient when dealing with wide spread social and economic problems.
Once again, government over-reach of citizens’ privacy is a considered solution to our problems.
Countries such as Sweden (which is expected to go entirely cashless by 2023) have been leading the charge in moving to a cashless world, and in Australia the government is preparing to ban cash transactions over ten thousand dollars in order to increase monitorization.
This road to a cashless society is being sped up by the coronavirus pandemic. There is correlation between countries where ‘cash is king’ and a high number of coronavirus infections. Many retail stores are now too afraid to accept cash due to possible virus transmission, with some outright refusing to transact with cash.
The erosion of privacy, and the gradual transition from cash to digital financial transactions leads us to murky waters. Will we be able to conduct private financial transactions five to ten years from now?
Throughout the past decade, unorthodox individuals turned to Bitcoin in order to transact privately. This led to the inception of popular online darknet markets such as the Silk Road. However, many of the darknet markets proved to be unreliable and short-lived. It soon became apparent to Bitcoin users that Bitcoin is not private, and many of those conducting transactions in relation to darknet markets were identified and prosecuted.
Blockchain analytic companies such as Chainanalysis gained traction and suddenly Bitcoin tumblers were found to be ineffective. Blockchain analytic companies take advantage of Bitcoin’s transparent blockchain, analysing data and tracking transaction outputs. The blockchain analytic company then sells this information to cryptocurrency exchanges and government organisations so they can link Bitcoin addresses to specific users. Many Bitcoin advocates tout Bitcoin can be used privately via the use of newer tumbling technologies, however this is a somewhat arduous process with no guarantee of its effectiveness. In December 2019 Chainanalysis demonstrated how they tracked transactions mixed via Wasabi Wallet that were associated with the PlusToken scam. Tumbling also leads to the possibility of coin taint, whereas certain Bitcoin may be perceived to be less valuable because they can be identified as being associated with nefarious activities, and as a result exchange services may confiscate coins when a user attempts to sell them.
While Bitcoin holds many desirable characteristics of sound money, many prominent figures within the Bitcoin space have repeatedly discussed on the need for default privacy and fungibility. However, as was seen in previous years’ block size dispute, the issue of privacy will come with great lengthy debate as stakeholders attempt to reach a consensus that does not impact upon the characteristics of Bitcoin.
As change within the social and financial landscape continues to accelerate, those seeking financial privacy may turn to Monero.
Monero is the elephant in the room.
Monero is a cryptocurrency similar to Bitcoin and shares many of the same characteristics of sound money, however it also provides default privacy. Unlike other privacy focused cryptocurrencies, privacy isn’t opt-in, so all transactions and wallet amounts are unknown and indistinguishable from one another. Every unit of Monero is valued equally as no matter its history. This allows Monero to be truly fungible, and eradicates any possibility of coin taint. It has proven this in a number of cases. For example, exchanges have been hesitant to list Monero due to KYC/AML compliance issues it raises because it is impossible to determine transaction history.
If Monero provides financial privacy solutions, why is Monero being ignored?
Firstly, while most deem privacy to be important, many are yet to find it necessary to adopt privacy technologies. There are many easy to use privacy solutions such as Signal or DuckDuckGo, however these are not widely used as users opt for convenience instead. As surveillance increases and data collected is harnessed to marginalize or punish users, it is like that privacy technologies will become extremely desirable. Additionally, acquiring Monero can be difficult or inconvenient for some, as cryptocurrency exchanges must comply with laws and regulations, and may perceive it to be a risk listing an untraceable cryptocurrency. This also leads to lower liquidity than other cryptocurrencies.
Monero remains a community driven project. Public figures such as John McAfee and Crypto Vigilante continue to advocate the use of Monero ahead of Bitcoin. Due to its humble and open-source nature, Monero isn’t widely promoted even though it maintains the third largest cryptocurrency community on Reddit after Bitcoin and Ethereum.
In respect to the technology, Monero’s hashrate has steadily been increasing over time, and the number of daily transactions taking place on the Monero blockchain are higher than ever. The Monero Research Lab continues its research in order to improve the protocol. Over the past few years these improvements resulted in reduced transaction fees, and enhanced scalability and privacy.
In just a few years from now, it is extremely likely traditional financial systems will not provide the capacity to transact privately. Banks will be required to ask questions regarding why certain transactions took place, and recorded transaction data will be sold to third parties. As the erosion of our privacy continues to accelerate, it won’t be long until Monero gains the use and recognition it deserves, and price reflects this.
Monero is what people think Bitcoin is.

Rolex Datejust 36mm Bimetal Green

Man did I wait for the wrong time to start buying reps or what? I had just bought my first TS Rep bag but it didn’t scratch my itch for getting things delivered, so I started buying a whole load of other things too. Which is how I ended up on Reptime and ended up buying this beauty.
UHh, those guys are scary over there, I think everyone in this sub would agree that they are highly intimidating 🤣 They really take Horology seriously over there so if you have genuine questions that can’t be easily found by a manual, you could get some great help!
However I couldn’t really wait another month for any watch I wanted to come all the way from China in this shipping disaster, so I headed over to their BST. Found a UK reseller and ordered this beautiful Rolex Datejust 36mm Stainless Steel and Yellow Gold 126233 Olive Green VI IX Roman Jubilee. Oh goodness was that a mouthful
TLDR; too impatient, want watch now.
REVIEW
Seller: BST wrist_reps (I believe he buys them bulk from TD’s and sells them for a slight profit for us lazies who want stock currently in UK)
W2C
Price from TD: $298 + $35 shipping (£272)
Price from BST: £270 ( I received discount for purchasing multiple items so I paid £252.5, shipping included.)
Payment Method: MasterCard preferred but they also take VISA, Bitcoin(8% discount), or Transferwise(5% discount). (I paid PayPal FF).
Order Timeline: May 12: Enquired and Payment made
May 13: Items shipped
May 14: Received
(Wouldn’t it be really nice if that is how swiftly EVERY order was)

QUALITY 9.5/10
Accuracy 9.25/10
Pros * I have attempted to get as as close a macro shot for the font and numbers and to me, unless you have them side by side with an auth and a macro lens, you can’t see the difference. * As far as the crown goes - the emblem on the dial, the screw down and the clasp - they all appear perfect to me. Even the etched crown which is only visible when I hit it with a light a certain angle is there. * At 11.8mm thick, it’s got the auth measurements down pat. I was initially worried if 36mm diameter would be too ‘big’ for me and I’ve found that I actually quite liked the size on my arm. It’s not broad either (at 43.3mm across the wrist), so could be worn by either ladies or gents. * The interior of the clasp is fully finished to a pretty high standard I would say. I tried to reflect this in the pictures. * The fluted bezel has a beautiful gem like cut on the yellow gold plated steel, and the light REALLY dances across the surface with this one.
Cons * As far as movement goes, it’s a silent glide, however I do think it could be a just a tad smoother (-0.5) * although the jubilee bracelet is beautiful,I haven’t fiddled with it yet, but the easylink adjustment extension seems a little hard to move (-0.25)
COMMUNICATION 10/10
It was a super easy transaction to make as this was on BST. Wristreps was kind and understanding. He didn’t need to offer me a discount for multiple purchases but he did. I believe everyone over in the Reptime sub are major fans of the TDs as well, so whoever you get either at Puretime or Trustytime has had great reviews. The ordering process on the site itself is pretty straightforward from what I can tell, and the TDs are easily found on Whatsapp and WeChat as well.
SATISFACTION 1000/10
I really am so in love with this watch That the other one I bought already hates me 😂 It’s the most beautiful colour and I think it compliments my skin tone well. I don’t know a whole lot about watches so I’m down to be educated.
I wrote and posted all of this on mobile so I’m going to reward myself with a BST wallet for my efforts

Amazing AMA from Douglas Horn

AMA Recap telos Foundation with Crypto Hunters
On August 02, 2020 at 12:00 WIB Indonesia Time / August 01 2020 at 10:00 PM ( PST ) in the Crypto Hunter Telegram Group, AMA TELOS started with Mr.Douglas as guest speaker and Gus Fahlev from Crypto Hunters as moderator. When campaigning, 10 lucky AMA participants when asking questions on Google forms and AMA sessions will get a total TELOS ( TLOS ) prize of $100.
The following is a summary of AMA questions and answers announced by the moderator and
Segment 1
Question 1: Can you explain us, what is Telos?
Answer: Telos is a blockchain platform for smart contracts. It is a low latency—a new block every half second, high capacity—currently in the top 2 blockchains in transactions per day, according to Blocktivity.info, and no transaction fee blockchain. Telos also has many unique features that allow developers to make better, dapps, such as our Telos Decide governance engine.
Question 2: what ecosystem is used by telos?
Answer: Telos is its own Layer-1 blockchain, not a token on another blockchain. The technology behind Telos is EOSIO, the same technology used by EOS and WAX, for example.
Question 3: I see that Telos uses EOSIO platform, what are the very significant advantages that distinguish Telos from other projects?
Answer: Telos uses the EOSIO platform but we have built several additional tools. Some of these add more security and resiliency to the blockchain, such as testing block producers and removing non-performant ones, but most are related to development. Telos provides attractive development tools that aren’t available elsewhere. Telos Decide is a governance platform that lets any group create self-governance tools easily. These run on Telos at very little cost and can provide all kinds of voting, elections, initiative ballots, committee management and funds allocation. Telos also has Telos EVM, an Ethereum virtual machine that can run Ethereum Solidity contracts at hundreds of times the speed of Ethereum and with no costs. Another Telos technology that is deploying soon is dStor, which is a decentralized cloud storage system associated with Telos so that dapps can store files controlled by blockchain contracts.
Question 4: At what stage is Teloa Road Map now? what are the latest updates currently being realized?
Answer: Telos launched its mainnet in December 2018 and has so far produced over 100,000,000 blocks without ever stopping or rolling back the chain. This is likely a record for a public blockchain. We have an ongoing group Telos Core Developers who build and maintain the code and are paid by our Telos Works funding system that is voted by the Telos token holders. Telos is a leader in blockchain governance and regularly amends its governance rules based on smart contract powered voting called Telos Amend. You can see the current Telos governance rules as stored live on the blockchain at tbnoa.org.
The most recent updates were adding new features to Telos Decide to make it more powerful, implementing EOSIO v2.0 which increased the capacity of Telos about 8-10 times what it previously was, and implementing Telos EVM on our Testnet.
We are currently working on better interfaces for Telos Decide voting, and building more infrastructure around Telos EVM so that it is ready to deploy on our mainnet.
Question 5: Is telos currently available on an exchange? and is it ready to be traded?
Answer: Telos has been trading on exchanges for over a year. The largest exchanges are Probit, CoinTiger, CoinLim, and P2PB2B. Other exchanges include Newdex and Alcor. We expect to be listed on larger exchanges in the near future.
Question 6: Now is the time when defi tokens begin to develop, can telos be categorized as a defi project? and what strategies for this year and in the years to come prepared by telos?
Answer: Telos is a smart contract platform, but it already has many DeFi tools built for it including REX staking rewards with a current yield of ~19% APR, smart contract controlled token swaps (like Bancor) with no counterparty called Telos Swaps, a common liquidity pool/order book shared by multiple DEXs to improve liquidity called EvolutionDEX. Wrapped BTC, ETH, XRP, EOS, and other tokens can be brought to Telos and exchanged or used via smart contracts through Transledger. We have more DeFi tools coming all the time including two new offerings in the next few weeks that will be the first of their kind.
Question 7: Governance is an important topic in blockchain and Telos is considered a leader in this area. Why is that?
Answer: Telos is among the top blockchain projects in terms of how it empowers its users to guide the growth of the chain—along the likes of Tezos or new DeFi tokens that offer governance coins. Telos users continuously elect the validating nodes, called Block Producers, that operate the network based on a set of governance documents such as the Telos Blockchain Network Operating Agreement (TBNOA). These are all stored entirely on-chain (viewable at tbnoa.org) and can be modified by smart contract through blockchain voting using Telos Amend. You can see examples of this at https://chainspector.io/governance/ratify-proposals Telos also has a robust user-voted funding mechanism called Telos Works that has funded many projects and is one of the more successful blockchain incubators around. Voting for all of these can be done in a number of ways including block explorers, wallets like Sqrl (desktop) and Telos Wallet (mobile), telos.net and Chainspector (https://chainspector.io/governance/telos-works). But Telos goes beyond any other chain-level governance by making all of these features and more available to any dapp on Telos through Telos Decide governance engine, making it easy for any dapp or DAO to add robust, highly customized voting.
Segment 2 from google form
Question 1: Defi projects are now trending whether telos will also go to Defi projects, to increase investors or the community?
Answer: Yes, we have several DeFi tools on Telos that can work together:
Telos Swaps is an automated, zero-counterparty token swapping smart contract where you can exchange any Telos tokens you may want at any time.
Telos has DEXs and uses a common order book called EvolutionDEX that's available to any DEX so that a buy order on one can be matched against a sell order on another. This greatly increases liquidity for traders.
We have staking rewards though the Resource EXchange (REX) with rewards currently at about 19% APR.
We also have "wrapped" BTC, ETH, and other tokens that can be traded on Telos or used by its smart contracts at half-second transaction times with no transaction fees. This makes Telos a Bitcoin or Ethereum second layer or state channel that's much faster even than Lightning Network and has no fees once the BTC has been brought to Telos.
Question 2: Telos aim is to build a new global economy could you explain how whole ecosystem works? There are already many centralized competitors so what is decentralization aspect in telos?
Answer: Telos is one of the most decentralized blockchain's in the world. It is operated by 51 validators (block producers) who validate blocks in any month. These are voted for on an ongoing basis by Telos account holders.
Telos is also economically decentralized with no large whales like Bitcoin, Ethereum, XRP or EOS because Telos never performed an ICO and limited the size of genesis accounts to 40,000 TLOS max.
Telos is also geographically decentralized with users and block producers on every continent but Antarctica and in numerous countries. The is a large amount in North America and Western Europe, but also in Asia, Australia, and large contingents in Latin America and Africa. Telos has had a Block Producer in Indonesia since the beginning and some dapps on Telos are based in Indonesia as well, like SEEDS, for example.
Question 3: Most investors focus only on the token price in the short term instead of the real value of the project.
Can #TELOS tell me the benefits for investors holding #TELOS the long term?
Answer: That's true about crypto speculators and traders, certainly. Traders are usually looking for coins with good positive momentuum that they hope will continue. But these are often pump and dumps where a few people get in early, pump the price, and then get out at the expense of new investors. That's very unfortunate. Telos isn't like this. One reason is that there aren't large whales who can easily manipulate the price.
Telos seems to be greatly undervalued compared to its peers. Telos has capacity like EOS and well above XRP, XML, Tron, Ethereum. But its value is miniscule relative to these. Telos is a leader in blockchain governance like Tezos but its marketcap is tiny in comparison. Telos onboarded 100,000 new accounts last month and is appearing in the leading crypto press every week with new dapps or developments. So there's some disconnect between the value of Telos and the price. In my experience, these tend to equalize once more people learn about a project.
Question 4: Eos Problems and How Telos Will Solve Them?
Answer: Telos originally set out to solve problems with EOS. It was successful in this and now Telos stands on it's own and our roadmap is more about empowering users. In short, these are some of the EOS problems we already solved:
RAM speculation - Telos had a plan to reduce RAM speculation through a published guidance price that has been extremely successful. The RAM price is guided by market forces but has remained within 10% of the guidance price since launch.
CPU resources - Telos implemented the Telos Resource Improved Management Plan many months ago which was a 7-point approach to making EIDOS-type resource mining unprofitable on Telos. It has largely been successful and Telos has not experienced any resource shortages.
Exchange Collusion/Voting - Telos governance does not permit Exchanges to vote with user tokens. This prevent voting situations seen on EOS or STEEM.
Block Producer collusion - Telos has minimum requirements for block producers and do not allow anyone to own more than one block producer. Those who are found doing so (there have been about 3 cases so far) have been removed and sanctioned in accordance with the rules of the TBNOA.
Question 5: What ecosystems do telos use? and why telos prefers to use EOS network over BEP2 or ERC20? what layer is used telos, can you please explain?
Answer: uses the EOSIO protocol because it is the fastest and most powerful in the world and it also receives the fastest upgrades and ongoing development compared to other blockchain technologies. EOS and WAX also use the EOSIO protocol but they are completely different chains.
Telos is a Layer 1 protocol, meaning that it is its own blockchain that other dapps and smart contracts deploy upon.
One thing that happens when a blockchain like Telos has much, much higher speed and capacity than others like Bitcoin or Ethereum is that Telos can actually run those other blockchains better on its own platform than they can natively. For example, a number of tokens can come in to Telos as wrapped tokens. BTC, ETH, XRP are all current examples of tokens that can be on Telos as wrapped tokens. Once there, these can all be moved around with half-second transaction times and no transaction fees, so they are a better second layer for Bitcoin or Ethereum than Lightning Network or Loom.
Telos can also emulate other chains, which we are doing using Telos EVM which emulates the Ethereum Virtual Machine at about 300 times faster and with no gas fees or congestion compared to Ethereum native deployment. Telos can run Ethereum (Solidity) smart contracts without any changes required. Telos EVM is already deployed on the Telos Testnet and will move to our mainnet soon. So anyone who wants to run ERC-20 tokens on Telos can do so easily and they will be faster and with much less cost than running the same contract on Ethereum.
Segment 3 free asking
Question: I am happy to see new things created by the Telos team. Like What concept did you build in 2020 to make Telos superior?
Answer: Currently, I think Telos Decide is the most unique and powerful feature we have built. There are all kinds of organizations that need to vote. Apartment buildings, school boards, unions, tribes, youth sports leagues, city councils. Voting is hard, time consuming, and expensive for many. Telos Decide makes voting easy, convenient, and transparent. That will be a major improvement and disrupt old style voting. It also goes for buisnesses and corporate governance. Even before COVID it was important, but now people can't really gather in one place so fraud-proof voting is very important. No one has the tools that Telos has. And if they try to copy us, well, we are already way out ahead working on the next features.
Question: If we look about partnerships, Telos has many partnership ! so what's the importance of that partnership for Telos? And How will you protect the value of Telos to your partners or investors ??
Answer: Many of the partnerships are dapps that have decided to deploy on Telos and receive some level of help from the TCD or Telos Foundation to do so. Once a dapp deploys on a chain, it really is like a long term partnership.
Many dapps will become block producers as well and join in the governance of Telos. I suspect that in a few years, most block producers will be the large dapps on the platform with just a few remaining like my company GoodBlock. Of course, we will have our own apps out as well so I guess we'll be developers too.
Telos is very fiscally responsible for investors. We spend little. There has not been any actual inflation on the chain in almost a year. (The token supply has remained unchanged at about 355M TLOS) we are actively working with dapps to bring more to Telos and exchanges and other services like fiat on- and off-ramps to increase value for users.
Question: In challenging crypto market condition any project is really difficult to survive and we are witnessing that there are many platforms . What is telos project plan for surviving in this long blockchain marathon? In this plan, what motivates long term investors and believers?
Answer: True.
While we currently have a low token price, Telos as a DPOS chain can be maintained and grow without a massive army of miners and still maintain BFT.
But the risk is really not whether Telos can continue. Already there are enough dapps that if the block producers went away somehow (not gonna happen) the dapps would just run the chain themselves.
But with 100,000 new users last month and new dapps all the time, we are looking to join the top 5 dapp platforms on DappRadar soon. Survival as a project is not in question.
One of the big reasons is that we never did any ICO and Telos is not a company. So regulatory risks aren't there and there's no company to go bankrupt or fail. We have already developed a bootstrapped system to pay block producers and core developers. So we aren't like a company that will run out of runway sometime.
Question: Could you explain what is DSTOR? What will it contribute to your ecosystem?
Answer: dStor is a decentralized cloud storage system that will have the performance of AWS or Azure with much lower costs and true decentralization. It's based on a highly modified version of IPFS that we have applied for patents for our implementation. It means that dapps will be able to store data like files, images, sound, etc. in a decentralized way.
Question: Trust and security is very important in any business , what makes investors , customer and users safe secure when working with TELOS??
Answer: Telos is decentralized in a way that's more like bitcoin than other blockchains (but without the whales who can manipulate price). There was never any single company that started Telos, so there's no company whose CEO could make decisions for the network. There are numerous block producers who decide on any operational issue that isn't clearly described in the TBNOA governance documents. And to get to an action, 15 of the 21 currently active BPs need to sign a multisig transaction. So that's a high threshold. But also, the TBNOA speaks to a large number of issues and so the BPs can't just make up their own rules.
Since there are really no whales, no one can vote in any kind of change or bring in their own BPs with their votes. This is also very different from other chains where there are whales. Telos is not located in any one country, so our rules can't be driven by one nation's politics.
All in all, this level of decentralization sets Telos apart from almost any blockchain project in existence. People don't have to trust Telos because the system is designed to make trust unnecessary.

Investing in Cryptocurrencies: “Ad2Bitcoin” Faucet

First article dedicated to the Advertising Faucet: earning money to invest in cryptocurrencies.
With this article we will introduce a new category of Faucet: the "Advertising". The difference with respect to the classic Faucets is inherent in the name itself: the amounts obtained from your claims or advertising returns will be reinvested in the internal circuit of the faucet with the aim of making your site known. You can then decide whether to re-invest the earned cryptocurrencies or transfer them to your personal wallet.

Ad2Bitcoin is one of the simplest Advertising Faucet ever.

Investing in Cryptocurrencies
Once logged in, you will find yourself on the main page, full of basic information on the use of banners and the main features of the site.
At the top you can see a menu divided as follows: My account, Referrals, Earn, Withdraw and Advertise.

Just below the title there are three images that lead to as many links:

Faucet, which allows you to earn a small amount of credits to spend on your advertising campaigns; Webiste, which refers to the Earn menu; Surfbar, which downloads a banner directly to your desktop, earning you some Satoshi Bitcoins by simply keeping it active.
Let's now describe the main menu:

My Account: lists, from top to bottom, the amount of Satoshi accumulated, the credits to be spent in personal advertising campaigns, the total visits obtained by the Ad2Bitcoin banners installed on your site and the relative time spent by users on the sites a to which the links of the aforementioned banners refer. The item "Total paid" instead shows the total of funds transferred to your personal wallet while Surfbar Stats shows the daily and total time statistics of the banner installed on the desktop.

Referrals: the page immediately shows the number of your subscribers, the total they have earned you and your referrals URL. The commission is set at 10%.
Below, a wide range of banners to choose the one you prefer based on size and appearance.


Earn: Unlike banners used in conjunction with your referral URL, these banners will earn you Satoshi and credits to spend on your advertising campaigns. You will then be able to invest the cryptocurrencies earned in advertising. There are 3 different versions already available in HTML format. Do not enter more than one per page.

Withdraw: in this section you can decide whether to transfer the funds directly to your personal wallet, with a minimum limit of 0.0005 Bitcoin and commission set at 0.00003 Bitcoin, or to your FaucetPanel account, without limits and without commissions.

Advertise: Here you can create your advertising campaign. After pressing Create a new banner AD, you will need to enter the title of the campaign, the link to the desired site, the link to your banner, choose its size and decide the sum of the cryptocurrencies you wish to invest in the aforementioned campaign. By selecting Create “Empty Ad” from the budget, you will spend your accumulated credits instead of the crypto. Finally select Start Campaign to start it immediately.
All easy and immediate.

We always remind new readers to visit the first article of our blog, where the more technical terms are explained.

See you soon!

MCS | What is DeFi's Playground Uniswap?

MCS | What is DeFi's Playground Uniswap?
\This post has been written by Hedgehog, an MCS influencer and one of Korea's famous cryptocurrency key opinion leaders.*

https://preview.redd.it/15cn7c8sg4i51.png?width=1024&format=png&auto=webp&s=a8cf9ee278cfe942cc536ae875d1bec4b331b00d
#Be_a_Trader!
Greetings from MCS, the derivatives trading platform where traders ALWAYS come first.

If you are an MCS trader interested in Defi, that is emerging and trending in the cryptocurrency industry, you will have heard of an exchange called Uniswap and know that Uniswap is a decentralized exchange. The concept of Uniswap's decentralized exchange is very different from the decentralized exchange (DEX) which trended in 2017-2018.

What is Uniswap?


https://preview.redd.it/g0d9s77tg4i51.png?width=470&format=png&auto=webp&s=2611450177d7a107a42f401c0f749f7693ce80e1
Uniswap is a decentralized exchange protocol. In short, it is an Ethereum-based protocol designed to facilitate automatic exchange transactions between Ethereum and ERC20 tokens. Uniswap is installed on-chain, so anyone can use this Uniswap protocol by installing a decentralized wallet like Metamask. Uniswap is loved by the cryptocurrency enthusiasts as it is a DeFi project that provides protection of assets when trading by decentralization.

How Does It Differ From Other DEXes?


https://preview.redd.it/4t7ijzxtg4i51.png?width=1922&format=png&auto=webp&s=1b9daba69637a54a82f92791a23401e13cd9f19e
The image above is a screenshot of Binance's Decentralized Exchange (DEX). Most Decentralized Exchanges (DEX) have similar UI/UXs as above. These decentralized exchanges (DEX) are different from centralized exchanges as they do not require deposits of cryptocurrency assets on the exchange but rather links it with personal wallets. The trading concept is no different from centralized exchanges.

https://preview.redd.it/y3zhz0vug4i51.png?width=868&format=png&auto=webp&s=b07d075b55a2e17c6822e0f124860a1411d61d5f
The image above is a screenshot of Uniswap's trade page. MCS traders who are new to Uniswap will have many questions like "What is this?" and "Can I trade with this?" Unlike traditional decentralized exchanges (DEXs), Uniswap has removed the order book. Instead, Uniswap introduced the Oracle concept and uses a pricing mechanism which guarantees liquidity and provide low spreads and slippage. These mechanisms are working successfully and are equipped with the concept of receiving incentives by providing liquidity utilizing the pool function on Uniswap.

Uniswap's Simple Market Making Mechanism

Uniswap guarantees liquidity using an automated market making mechanism. ERC-20 tokens traded in Uniswap has an Ethereum pool and token pool, and at a specific time, the token price is determined by the ratio of the Ethereum pool and the token pool size. Every time someone receives Ethereum from Uniswap by selling tokens, the amount of tokens increase and Ethereum decreases. In this case, the token price will gradually decrease by mechanism. Conversely, whenever someone gives Ethereum and buys a token, the corresponding token in the pool decreases, and the Ethereum quantity increases, so the mechanism increases the token price. As such, the token price is determined by an automated market making algorithm by checking the amount of Ethereum and token remaining in the token pool.

Incentivized Liquidity on Uniswap

Uniswap's automatic market making mechanism provides its own liquidity. However, it requires a significant pool of Ethereum and tokens to run smoothly. Uniswap incentivizes this liquidity by rewarding those who contribute to Ethereum and token pools. When each transaction occurs, part of the transaction fee is compensated to those who provide liquidity, and the size of the reward is proportional to the contribution ratio of the token pool liquidity.

Uniswap's Exponential Growth


https://preview.redd.it/sxcmgsqvg4i51.png?width=1340&format=png&auto=webp&s=57dfbfc8b44ea40a92b9b7ea1bb00ee3e5d23d69
According to an article on coinDesk on the 13th, citing Dune Analytics data, Uniswap's trading volume from August 1st to 12th was approximately $1.76 billion. This volume has already exceeded the monthly volume of July which was $1.75 billion. As shown in the chart above, the monthly trading volume of Uniswap has succeeded in breaking a record high for 4 consecutive months and it still continues to grow.

BuilderException when running Electrum in Kivy mode from source on desktop

Update:

There is a themeing makefile that I missed in the FAQ which is the cause of the issue.
Electrum is a fairly major Android open-source bitcoin wallet written in Kivy. In theory, the same source should render on desktop as well, but I can't seem to get it to work. I'm getting the following error:
``` kivy.lang.builder.BuilderException: Parser: File "/src/electrum.git/electrum/gui/kivy/main.kv", line 214: ... 212: rgba: 0.192, .498, 0.745, 1 213: BorderImage:

The referenced path electrum/gui/kivy/theming/light only contains PNG files.
The full Kivy log and python traceback are included in the Github issue linked above.
Anyone familiar with the Electrum source? Any clues as to what is happening other than File Not Found

Why i’m bullish on Zilliqa (long read)

Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analysed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralised and scalable in my opinion.
 
Below I post my analysis why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
 
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
 
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise just skim through and once you are zoning out head to the next part.
 
Technology and some more:
 
Introduction The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
 
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
 
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
 
Mainnet is live since end of January 2019 with daily transaction rate growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralised and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. Maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
 
Zilliqa realised early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralised, secure and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in amount of nodes. More nodes = higher transaction throughput and increased decentralisation. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
 
Before we continue disecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
 
Down the rabbit hole
 
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
 
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
 
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here.
Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
 
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
 
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as:
“A peer-to-peer, append-only datastore that uses consensus to synchronise cryptographically-secure data”.
 
Next he states that: >“blockchains are fundamentally systems for managing valid state transitions”.* For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
 
With public blockchains like Zilliqa this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network etc.
 
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
 
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralised and scalable being low.
 
pBFT stands for practical Byzantine Fault Tolerance and is an optimisation on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
 
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017.
Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
 
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (>66%) double spend attacks become possible.
 
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
 
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT etc. Another thing we haven’t looked at yet is the amount of decentralisation.
 
Decentralisation
 
Currently there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralised nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching their transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand.
Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
 
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public.They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
 
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers.The 5% block rewards with an annual yield of 10.03% translates to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
 
With a high amount of DS & shard nodes and seed nodes becoming more decentralised too, Zilliqa qualifies for the label of decentralised in my opinion.
 
Smart contracts
 
Let me start by saying I’m not a developer and my programming skills are quite limited. So I‘m taking the ELI5 route (maybe 12) but if you are familiar with Javascript, Solidity or specifically OCaml please head straight to Scilla - read the docs to get a good initial grasp of how Zilliqa’s smart contract language Scilla works and if you ask yourself “why another programming language?” check this article. And if you want to play around with some sample contracts in an IDE click here. Faucet can be found here. And more information on architecture, dapp development and API can be found on the Developer Portal.
If you are more into listening and watching: check this recent webinar explaining Zilliqa and Scilla. Link is time stamped so you’ll start right away with a platform introduction, R&D roadmap 2020 and afterwards a proper Scilla introduction.
 
Generalised: programming languages can be divided into being ‘object oriented’ or ‘functional’. Here is an ELI5 given by software development academy: > “all programmes have two basic components, data – what the programme knows – and behaviour – what the programme can do with that data. So object-oriented programming states that combining data and related behaviours in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behaviour are different things and should be separated to ensure their clarity.”
 
Scilla is on the functional side and shares similarities with OCaml: > OCaml is a general purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
 
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognised by academics and won a so called Distinguished Artifact Award award at the end of last year.
 
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities safety is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts it inherently involves cryptocurrencies in some form thus value.
 
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa for Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
 
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”. Scilla design story part 1
 
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
 
Scilla also allows for formal verification. Wikipedia to the rescue:
In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
 
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
 
Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
 
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
 
Smart contract on a sharded environment and state sharding
 
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
 
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
 
And this is where the downsides of state sharding comes in currently. All shards in Zilliqa have access to the complete state. Yes the state size (0.1 GB at the moment) grows and all of the nodes need to store it but it also means that they don’t need to shop around for information available on other shards. Requiring more communication and adding more complexity.

Roadmap / Zilliqa 2.0
 
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
 
Business & Partnerships  
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organisations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggest that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
 
Zilliqa seems to already taking advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, AirBnB, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
 
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
 
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
 
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are build on top of these blocks.
 
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”*
 
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
 
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They dont just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
 
Marketing & Community
 
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities) also seem to be growing.
 
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiatives (correct me if I’m wrong though). This suggest in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
 
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
 
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
 
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures & Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
