How to set up a secure offline savings wallet - BitcoinWiki

I set up my BTC in an offline Armory wallet with whatever the highest security settings available were. I have it stored safely on a paper. This was a few years ago -- is Armory still utilized / will anything ever happen that prevents me from accessing this offline wallet? /r/Bitcoin

Ultimate glossary of crypto currency terms, acronyms and abbreviations

I thought it would be really cool to have an ultimate guide for those new to crypto currencies and the terms used. I made this mostly for beginner’s and veterans alike. I’m not sure how much use you will get out of this. Stuff gets lost on Reddit quite easily so I hope this finds its way to you. Included in this list, I have included most of the terms used in crypto-communities. I have compiled this list from a multitude of sources. The list is in alphabetical order and may include some words/terms not exclusive to the crypto world but may be helpful regardless.
2FA
Two factor authentication. I highly advise that you use it.
51% Attack:
A situation where a single malicious individual or group gains control of more than half of a cryptocurrency network’s computing power. Theoretically, it could allow perpetrators to manipulate the system and spend the same coin multiple times, stop other users from completing blocks and make conflicting transactions to a chain that could harm the network.
Address (or Addy):
A unique string of numbers and letters (both upper and lower case) used to send, receive or store cryptocurrency on the network. It is also the public key in a pair of keys needed to sign a digital transaction. Addresses can be shared publicly as a text or in the form of a scannable QR code. They differ between cryptocurrencies. You can’t send Bitcoin to an Ethereum address, for example.
Altcoin (alternative coin): Any digital currency other than Bitcoin. These other currencies are alternatives to Bitcoin regarding features and functionalities (e.g. faster confirmation time, lower price, improved mining algorithm, higher total coin supply). There are hundreds of altcoins, including Ether, Ripple, Litecoin and many many others.
AIRDROP:
An event where the investors/participants are able to receive free tokens or coins into their digital wallet.
AML: Defines Anti-Money Laundering laws**.**
ARBITRAGE:
Getting risk-free profits by trading (simultaneous buying and selling of the cryptocurrency) on two different exchanges which have different prices for the same asset.
Ashdraked:
Being Ashdraked is essentially a more detailed version of being Zhoutonged. It is when you lose all of your invested capital, but you do so specifically by shorting Bitcoin. The expression “Ashdraked” comes from a story of a Romanian cryptocurrency investor who insisted upon shorting BTC, as he had done so successfully in the past. When the price of BTC rose from USD 300 to USD 500, the Romanian investor lost all of his money.
ATH (All Time High):
The highest price ever achieved by a cryptocurrency in its entire history. Alternatively, ATL is all time low
Bearish:
A tendency of prices to fall; a pessimistic expectation that the value of a coin is going to drop.
Bear trap:
A manipulation of a stock or commodity by investors.
Bitcoin:
The very first, and the highest ever valued, mass-market open source and decentralized cryptocurrency and digital payment system that runs on a worldwide peer to peer network. It operates independently of any centralized authorities
Bitconnect:
One of the biggest scams in the crypto world. it was made popular in the meme world by screaming idiot Carlos Matos, who infamously proclaimed," hey hey heeeey” and “what's a what's a what's up wasssssssssuuuuuuuuuuuuup, BitConneeeeeeeeeeeeeeeeeeeeeeeect!”. He is now in the mentally ill meme hall of fame.
Block:
A package of permanently recorded data about transactions occurring every time period (typically about 10 minutes) on the blockchain network. Once a record has been completed and verified, it goes into a blockchain and gives way to the next block. Each block also contains a complex mathematical puzzle with a unique answer, without which new blocks can’t be added to the chain.
Blockchain:
An unchangeable digital record of all transactions ever made in a particular cryptocurrency and shared across thousands of computers worldwide. It has no central authority governing it. Records, or blocks, are chained to each other using a cryptographic signature. They are stored publicly and chronologically, from the genesis block to the latest block, hence the term blockchain. Anyone can have access to the database and yet it remains incredibly difficult to hack.
Bullish:
A tendency of prices to rise; an optimistic expectation that a specific cryptocurrency will do well and its value is going to increase.
BTFD:
Buy the fucking dip. This advise was bestowed upon us by the gods themselves. It is the iron code to crypto enthusiasts.
Bull market:
A market that Cryptos are going up.
Consensus:
An agreement among blockchain participants on the validity of data. Consensus is reached when the majority of nodes on the network verify that the transaction is 100% valid.
Crypto bubble:
The instability of cryptocurrencies in terms of price value
Cryptocurrency:
A type of digital currency, secured by strong computer code (cryptography), that operates independently of any middlemen or central authoritie
Cryptography:
The art of converting sensitive data into a format unreadable for unauthorized users, which when decoded would result in a meaningful statement.
Cryptojacking:
The use of someone else’s device and profiting from its computational power to mine cryptocurrency without their knowledge and consent.
Crypto-Valhalla:
When HODLers(holders) eventually cash out they go to a place called crypto-Valhalla. The strong will be separated from the weak and the strong will then be given lambos.
DAO:
Decentralized Autonomous Organizations. It defines A blockchain technology inspired organization or corporation that exists and operates without human intervention.
Dapp (decentralized application):
An open-source application that runs and stores its data on a blockchain network (instead of a central server) to prevent a single failure point. This software is not controlled by the single body – information comes from people providing other people with data or computing power.
Decentralized:
A system with no fundamental control authority that governs the network. Instead, it is jointly managed by all users to the system.
Desktop wallet:
A wallet that stores the private keys on your computer, which allow the spending and management of your bitcoins.
DILDO:
Long red or green candles. This is a crypto signal that tells you that it is not favorable to trade at the moment. Found on candlestick charts.
Digital Signature:
An encrypted digital code attached to an electronic document to prove that the sender is who they say they are and confirm that a transaction is valid and should be accepted by the network.
Double Spending:
An attack on the blockchain where a malicious user manipulates the network by sending digital money to two different recipients at exactly the same time.
DYOR:
Means do your own research.
Encryption:

Fiat money:
Fiat currency is legal tender whose value is backed by the government that issued it, such as the US dollar or UK pound.
Fork:
A split in the blockchain, resulting in two separate branches, an original and a new alternate version of the cryptocurrency. As a single blockchain forks into two, they will both run simultaneously on different parts of the network. For example, Bitcoin Cash is a Bitcoin fork.
FOMO:
Fear of missing out.
Frictionless:
A system is frictionless when there are zero transaction costs or trading retraints.
FUD:
Fear, Uncertainty and Doubt regarding the crypto market.
Gas:
A fee paid to run transactions, dapps and smart contracts on Ethereum.
Halving:
A 50% decrease in block reward after the mining of a pre-specified number of blocks. Every 4 years, the “reward” for successfully mining a block of bitcoin is reduced by half. This is referred to as “Halving”.
Hardware wallet:
Physical wallet devices that can securely store cryptocurrency maximally. Some examples are Ledger Nano S**,** Digital Bitbox and more**.**
Hash:
The process that takes input data of varying sizes, performs an operation on it and converts it into a fixed size output. It cannot be reversed.

Pre mining:
The mining of a cryptocurrency by its developers before it is released to the public.
Proof of stake (POS):
A consensus distribution algorithm which essentially rewards you based upon the amount of the coin that you own. In other words, more investment in the coin will leads to more gain when you mine with this protocol In Proof of Stake, the resource held by the “miner” is their stake in the currency.
PROOF OF WORK (POW) :
The competition of computers competing to solve a tough crypto math problem. The first computer that does this is allowed to create new blocks and record information.” The miner is then usually rewarded via transaction fees.
Protocol:
A standardized set of rules for formatting and processing data.
Public key / private key:
A cryptographic code that allows a user to receive cryptocurrencies into an account. The public key is made available to everyone via a publicly accessible directory, and the private key remains confidential to its respective owner. Because the key pair is mathematically related, whatever is encrypted with a public key may only be decrypted by its corresponding private key.
Pump and dump:

Recovery phrase:
A set of phrases you are given whereby you can regain or access your wallet should you lose the private key to your wallets — paper, mobile, desktop, and hardware wallet. These phrases are some random 12–24 words. A recovery Phrase can also be called as Recovery seed, Seed Key, Recovery Key, or Seed Phrase.

“Funds are safe."
“the exchage I use got hacked!”“Oh no, are your funds safu?”
“My coins better be safu!”


Sats/Satoshi:
The smallest fraction of a bitcoin is called a “satoshi” or “sat”. It represents one hundred-millionth of a bitcoin and is named after Satoshi Nakamoto.
Satoshi Nakamoto:
This was the pseudonym for the mysterious creator of Bitcoin.
Scalability:
The ability of a cryptocurrency to contain the massive use of its Blockchain.
Sharding:
A scaling solution for the Blockchain. It is generally a method that allows nodes to have partial copies of the complete blockchain in order to increase overall network performance and consensus speeds.

Shill:
Spreading buzz by heavily promoting a particular coin in the community to create awareness.
Short position:
Selling of a specific cryptocurrency with an expectation that it will drop in value.

Surge:
When a crypto currency appreciates or goes up in price.
Tank:
The opposite of mooning. When a coin tanks it can also be described as crashing.
Tendies
For traders , the chief prize is “tendies” (chicken tenders, the treat an overgrown man-child receives for being a “Good Boy”) .
Token:
A unit of value that represents a digital asset built on a blockchain system. A token is usually considered as a “coin” of a cryptocurrency, but it really has a wider functionality.
TOR: “The Onion Router” is a free web browser designed to protect users’ anonymity and resist censorship. Tor is usually used surfing the web anonymously and access sites on the “Darkweb”.
Transaction fee:
An amount of money users are charged from their transaction when sending cryptocurrencies.
Volatility:
A measure of fluctuations in the price of a financial instrument over time. High volatility in bitcoin is seen as risky since its shifting value discourages people from spending or accepting it.
Wallet:
A file that stores all your private keys and communicates with the blockchain to perform transactions. It allows you to send and receive bitcoins securely as well as view your balance and transaction history.
Whale:
An investor that holds a tremendous amount of cryptocurrency. Their extraordinary large holdings allow them to control prices and manipulate the market.
Whitepaper:

What I currently use for privacy (after almost 2 years of long investing into it)

First of all, my threat model: I'm just an average person that wants to AVOID the maximum I can to be monitored and tracked by the government and big corps, a lot of people out there REALLY hate me and I've gone through lots of harassment and other stuff, I also plan to take my activism and love for freedom more seriously and to do stuff that could potentially lead me to very high danger or even put my life on the line. That being said, my main focus is on something that is privacy-friendly but also something with decent security (no point having a lot of privacy if a script kiddie can just break into it an boom, everything is gone) anonymity is also desirable but I'm pretty aware that true 100% anonymity is simply not possible and to achieve the maximum you can of it currently you'd have to give up A LOT of stuff in which I don't think I really could. So basically, everything that I said + I don't want to give up some hobbies of mine (as playing games etc)
Here's what I use/have done so far, most of it is based on privacytools.io list and research I've done.
Mobile:
Google Pixel 3a XL running GrapheneOS
Apps: Stock apps (Vanadium, Gallery, Clock, Contacts etc) + F-DROID, NewPipe, OsmAnd+, Joplin, Tutanota, K-9 Mail, Aegis Authenticator, KeePassDX, Syncthing, Signal, Librera PRO, Vinyl, Open Camera and Wireguard.
I also use BlahDNS as my private DNS.
Other smartphone stuff/habits: I use a Supershieldz Anti Spy Tempered Glass Screen Protector on my phone and I also have a Faraday Sleeve from Silent Pocket which my phone is on most of the times (I don't have smartphone addiction and would likely advice you to break free from smartphone addiction if you have it). I NEVER use bluetooth (thank god Pixel 3a have a headphone jack so yeah, no bluetooth earphones here) and always keep my Wi-Fi off if I'm not using it.
Computer:
I have a desktop that I built (specs: Asus B450M Gaming, AMD Ryzen 3 3300X, Radeon RX 580 8GB, 16GB DDR4 2666Mhz, 3TB HDD, 480GB SSD) that is dualbooted with QubesOS and Arch Linux.
Qubes is my main OS that I use as daily driver and for my tasks, I use Arch for gaming.
I've installed linux-hardened and its headers packages on my Arch + further kernel hardening using systctl and boot parameters, AppArmor as my MAC system and bubblewrap for sandboxing programs. I also spoof my MAC address and have restricted root access, I've also protected my GRUB with password (and use encrypted boot) and have enabled Microcode updates and have NTP and IPV6 disabled.
Also on Arch, I use iptables as a firewall denying all incoming traffic, and since it's my gaming PC, I don't game on the OS, instead, I use a KVM/QEMU Windows VM for gaming (search "How I Built The "Poor-Shamed" Computer" video to see what I'm talking about) I also use full disk encryption.
Software/Providers:
E-Mails: I use ProtonMail (Plus Account paid with bitcoin) and Tutanota (free account as they don't accept crypto payment yet, come on Tutanota, I've been waiting for it for 2 years already) since I have plus account on ProtonMail it allows me to use ProtonMail Bridge and use it on Claws Mail (desktop) and K-9 Mail (mobile) as for Tutanota I use both desktop and mobile app.
Some other e-mails habits of mine: I use e-mail aliases (ProtonMail plus account provides you with 5) and each alias is used for different tasks (as one for shopping, one for banking, one for accounts etc) and none of my e-mails have my real name on it or something that could be used to identify me. I also highly avoid using stuff that require e-mail/e-mail verification for usage (e-mail is such a pain in the ass tbh) I also make use of Spamgourmet for stuff like temporary e-mail (best service I found for this doing my research, dunno if it's really the best tho, heard that AnonAddy does kinda the same stuff but dunno, recommendations are welcomed)
Browsers/Search Engine: As mentioned, I use Vanadium (Graphene's stock browser) on mobile as it is the recommended browser by Graphene and the one with the best security for Android, for desktop I use a Hardened Firefox (pretty aware of Firefox's security not being that good, but it's the best browser for PC for me as Ungoogled Chromium is still not there in A LOT of things + inherent problems of Chrome as not being able to disable WebRTC unless you use an extension etc) with ghacks-user.js and uBlock Origin (hard mode), uMatrix (globally blocking first party scripts), HTTPS Everywhere (EASE Mode), Decentraleyes (set the recommended rules for both uBlock Origin and uMatrix) and Temporary Containers as addons. I also use Tor Browser (Safest Mode) on a Whonix VM on Qubes sometimes. DuckDuckGo is my to-go search engine and I use DNS over HTTPS on Firefox (BlahDNS as my provider once again)
browsing habits: I avoid JavaScript the maximum I can, if it's really needed, I just allow the scripts temporarely on uBlock Origin/uMatrix and after I'm done I just disable it. I also generally go with old.reddit.com instead of reddit.com (as JavaScript is not required to browse the old client), nitter.net for checking twitter stuff (although I rarely have something peaking my interest on Twitter) and I use invidious.snopyta.org as youtube front-end (I do however use YouTube sometimes if a video I wanna see can't be played on invidious or if I wanna watch a livestream) and html.duckduckgo.com instead of duckduckgo.com other than avoiding JavaScript most of my browsing habits are just common sense at this point I'd say, I also use privatebin (snopyta's instance) instead of pastebin. I also have multiple firefox profiles for different tasks (personal usage, shopping, banking etc)
VPN: I use Mullvad (guess you can mention it here since it's PTIO's recommended) paid with bitcoin and honestly best service available tbh. I use Mullvad's multihop implementation on Wireguard which I manually set myself as I had the time and patience to learn how.
password manager: KeePassXC on desktop and KeePassDX on my smartphone, my password database for my desktop is stored on a USB flash driver I encrypted with VeraCrypt.
some other software on desktop: LibreOffice (as a Microsoft Office substitute), GIMP (Photshop substitute), Vim (I use it for multiple purposes, mainly coding IDE and as a text editor), VLC (media player), Bisq (bitcoin exchange), Wasabi (bitcoin wallet), OBS (screen recording), Syncthing (file sync), qBitTorrent (torrent client) and Element (federated real-time communication software). I sadly couldn't find a good open-source substitute to Sony Vegas (tested many, but none was in the same level of Vegas imo, KDENLive is okay tho) so I just use it on a VM if I need it (Windows VM solely for the purpose of video editing, not the same one I use for gaming)
Other:
router: I have an Asus RT-AC68U with OpenWRT as its firmware. I also set a VPN on it.
cryptocurrency hardware wallet: I store all of my cryptocurrency (Bitcoin and Monero) on a Ledger Nano S, about 97% of my money is on crypto so a hardware wallet is a must for me.
I have lots of USB flash drivers that I use for Live ISOs and for encrypted backups. I also have a USB Data Blocker from PortaPow that I generally use if I need to charge my cellphone in public or in a hotel while on a trip (rare occasion tbh).
I have a Logitech C920e as webcam and a Blue Yeti microphone in which I never let them plugged, I only plug them if it's necessary and after I'm done I just unplug them.
I also have a Nintendo Switch Lite as a gaming console that I most of the times just use offline, I just connect to the internet if needed for a software update and then just turn the Wi-Fi off from it.
Other Habits/Things I've done:
payments: I simply AVOID using credit card, I try to always pay on cash (I live in a third-world country so thank god most of people here still depend on cash only) physically and online I try my best to either by using cryptocurrency or using gift cards/cash by mail if crypto isn't available. I usually buy crypto on Bisq as I just don't trust any KYC exchange (and neither should you) and since there aren't many people here in my area to do face to face bitcoin trade (and I'm skeptical of face to face tbh), I use the Wasabi Wallet (desktop) to coinjoin bitcoin before buying anything as this allows a bit more of privacy, I also coinjoin on Wasabi before sending my bitcoins to my hardware wallet. I also don't have a high consumerism drive so I'm not constantly wanting to buy everything that I see (which helps a lot on this criteria)
social media/accounts: as noted, aside from Signal and Element (which I don't even use that often) I just don't REALLY use any social media (tried Mastodon for a while but I was honestly felt it kinda desert there and most of its userbase from what I've seen were some people I'd just... rather don't hang with tbh) and, althoug not something necessary is something that I really advise people to as social media is literally a poison to your mind.
I also don't own any streaming service like Netflix/Amazon Prime/Spotify etc, I basically pirate series/movies/songs and that's it.
I've also deleted ALL my old accounts from social media (like Twitter etc) and old e-mails. ALL of my important and main accounts have 2FA enabled and are protected by a strong password (I use KeePass to generate a 35 character lenght password with numbers, capital letters, special symbols etc, each account uses a unique password) I also NEVER use my real name on any account and NEVER post any pictures of myself (I rarely take pictures of stuff if anything)
iot/smart devices: aside from my smartphone, I don't have any IOT/smart device as I honestly see no need for them (and most of them are WAY too expensive on third-world countries)
files: I constatly backup all of my files (each two weeks) on encrypted flash drivers, I also use BleachBit for temporary data cleaning and data/file shredding. I also use Syncthing as a substitute to stuff like Google Drive.
Future plans:
learn to self-host and self-host an e-mail/NextCloud (and maybe even a VPN)
find something like BurneHushed but FOSS (if you know any please let me know)
So, how is it? anything that I should do that I'm probably not doing?

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.

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.

Running My Own Tor Bitcoin Lightning Node

I've been using my own bitcoin lightning/full node for about a month now and would like to share my findings as well as ask a few questions to the community.
For those that might be curious as to my setup, I am using a Lenovo M900 ThinkCentre with a 1 TB Samsung SSD and 32GB of ram. I'm actually running several VM's on it, for different reasons. One of which is the full Bitcoin/lightning node using Ubuntu Desktop in which I dedicate 8 GB to (more than enough) and most of my disk space to. I wanted a power efficient setup so that I could keep it running 24/7 and this is about as good as it gets short of a Raspberry Pi. When I only have my Bitcoin VM running, I'm consuming ~10 Watts. With everything else running it's ~30 Watts. I bought all of the equipment used (apart from the ram) so it was very cost effective.
What I've learned in my experience:

Any info would be appreciated. If anybody has any question that they would like to ask me, feel free to ask!

Best places to trade your Ripple/XRP (longer read)

In the past when you heard the word ‘cryptocurrency’, the first thing that came to everyone’s minds was Bitcoin. To some, this is still the case; they believe that Bitcoin is the cryptocurrency and the vice versa to also be true.
Of course, the statement is correct in one way; Bitcoin is a cryptocurrency, but cryptocurrency is not made up of only Bitcoin but a host of other currencies. One of these currencies is Ripple.
When it comes to the top five cryptocurrencies with the highest capitalization, Ripple needs no introduction as it has managed to secure a position of being the third most traded cryptocurrency around the world. Perhaps this is due to the fact that Ripple is the only cryptocurrency with a backing from traditional legacy financial institutions.
In addition, the coin has been integrated into the operation of thousands of small businesses around the world.
At this juncture, it is only fair that you learn how to be a part of this great innovation. Thankfully, that is what this guide is all about, showing you some of the best trading platforms for Ripple.
There are numerous exchanges that offer decent exchange rates and well-matched trading pairs, but I’ll only narrow down to some of our best picks to help you get started fast.

What is Ripple (XRP)?

Ripple is a cryptocurrency, a currency exchange, a real-time gross settlement payment system, and a remittance network powered by Ripple. As I mentioned before, this is the third most capitalized cryptocurrency asset after Bitcoin and Ethereum.
XRP allows enterprises such as banks and other financial service providers to offer their clients a reliable option to source for liquidity for cross-border currency transactions.
Ripple is a distributed, open-source platform that seeks to capitalize on the weaknesses of the conventional money payment systems such as credit and debit cards, PayPal, bank transfers, among others. According to Ripple, these payment systems expose users to a lot of transaction delays and restrict the fluidity of currencies.
The platform aims at replacing traditional payment systems through offering a faster, safer, and more convenient alternative for making payments.
Both the platform’s exchange and tokens are called Ripple, and their mantra states one frictionless experience to send money globally.

Where Can I Trade XRP?

Most exchanges that trade Ripple are limited to crypto-to-crypto transactions. This means that you can only trade Ripple with another cryptocurrency and not fiat currencies such as the euro or the dollar.
You’ll need to acquire the currency you wish to trade with XRP on a platform that accepts fiat, and once that happens, you can proceed to trade the two currencies.
There are several great platforms that offer XRP trading; below are just a few:

Buying XRP on Binance

Binance is an exchange that was established in 2017 but has bagged a reputation worth over 10 years of existence. This, the team claims, is due to a number of features offered by the platform including better security controls, low trading fee (0.05%), as well as its faster transacting speeds.
To buy or trade XRP on Binance, you’ll need to set up an account on the exchange. The platform offers a fast signup process and actually accepts users from all around the world.
Once you’re done signing up, navigate to the fund’s section and click on “Deposits”. You will find all the listed cryptocurrencies supported by the Binance platform.
Since Binance does not support the purchase of Ripple using fiat currencies, you’ll need to acquire another cryptocurrency such as Bitcoin or Ethereum and use it to acquire XRP.
This will require you to use a platform such as Coinbase that accepts fiat currencies when buying cryptos. Getting started on Coinbase is quite simple. Head over to their website and click on the “Get Started” icon on the top right corner of your screen.
Fill in the required fields and read through their User Agreement and Privacy Policy documents, then create your account.
You’ll receive an email that will require you to verify your signup details together with your phone number.
You will then gain access to your created account.
Proceed to buy your coins; preferably, choose either Bitcoin or Ethereum as they have higher liquidities. Once you’re done, your coins will be received in your online Coinbase account.
Head over to the menu indicated as “Account” and click on it.
Click on “Send” and enter the number of coins you wish to send to your Binance wallet. Copy and paste the address of your Binance account to Coinbase, then click send to transfer the funds.
The purchased cryptocurrency will be received and on Binance, you can go ahead and trade it with Ripple.

Buying XRP on Bittrex

Just like on Binance, you’ll need to create an account on Bittrex to get started.
The process is pretty much straightforward, only requiring you to sign up using your email address and password.
Once you’re done signing up, click on the wallet tab. You will be taken to a page where you can view all the deposit addresses of the cryptocurrencies on the Bittrex platform.
You can then choose the currency to use to purchase XRP, after which, you will be required to type in the code of the currency you will be using to purchase Ripple. If you’re using Ethereum, you can type in the search bar “ETH” and then click on the green arrow to reveal the deposit address. In case you will be sending the funds from a different exchange, you’ll need to paste the address to that platform.
Next, you’ll need to send funds to your Bittrex account. Bittrex permits payments using both fiat and cryptocurrencies. So, depending on what you will be using, send money to your online wallet and proceed to trade it with Ripple.

Buying XRP on Changelly

Changelly is another Ripple exchange that requires you to use either Bitcoin or Ethereum to acquire XRP.
The exchange doesn’t have an inbuilt wallet, so you’ll need to store your funds on a separate hardware or software wallet. You can pretty much use any type of wallet, but the most secure ones are the hardware ones as they store your coins in an offline cold storage area.
Ripple prefers not to have many unutilized accounts being set up on its platform; this is why you’ll need to have a minimum of 20 XRP in your account for you to get started. However, if your first transaction will be more than 20 XRP, then you’re all set.
Once you have a wallet ready for your Ripple, head to the Changelly site and click on “input currency”. Here, you will be able to enter the currency you wish to trade for Ripple.
You can basically pick and use any coin listed on the site, but it is highly recommended that you use either Bitcoin or Ethereum due to their high liquidity.
The output section will have Ripple, which is the currency you wish to receive.
The next step will require you to key in your XRP address, which is your Ripple address and the destination tag, which is a description of the transaction.
You can now proceed to trade your chosen coins for Ripple. The transaction shouldn’t take long, and you will be able to receive the coins in your Ripple wallet.

Cryptmixer

Cryptmixer is a platform that assists users to swap XRP with 5 other assets freely. The interface lets users convert assets directly from one’s wallet, without having to create an account or register. Besides, the service helps to compare different providers and find a suitable deal for handling Ripple transactions securely, rapidly, and at the best rate.
The process of using Cryptmixer is quite simple:
  1. Go to the main page, choose the currency you’d like to swap, and enter the amount.
  2. Choose XRP to receive.
  3. Review the amount to see how much you will receive. Cryptmixer will automatically find the best rates for your trade.
  4. Click Exchange.
  5. Then, enter the wallet address that you wish to use.
  6. Send in the deposit to the generated wallet address and wait for the transaction to be processed.

Buying XRP on Coinmama

Coinmama is a cryptocurrency exchange that has been around for quite a while now. The Coinmama team has been adding more coins on their platform over time to be able to provide its users with a wider variety of trading pairs.
More recently, the platform included Ripple on its platform. However, Coinmama does not allow US-based users to purchase Ripple due to some stringent laws and regulations surrounding the coin.
But for non-US users, you can proceed to create your account on the platform and locate Ripple among the listed assets.
Once you’ve created your account, navigate your way to the area with the list of assets. Select one of the provided packages and proceed.
You’re required to have a crypto wallet prior to making any purchase on the platform, so be sure to have a valid wallet address before completing the purchase. Once that’s done, purchase your Ripple coins and they will be delivered to your wallet.

Storing Your Ripple Coins

Online storages are never safe for cryptocurrency assets. Individuals have woken up to all sort of horrific sceneries on their accounts that left them bankrupt with no one to turn to.
One of the most important concepts you need to grasp about online businesses is the security of your transactions.
Cryptocurrency burglars are everywhere and are getting smarter by the day; this means that traditional ways of guaranteeing the security of your online assets are no longer effective.
Most exchanges have top-notch security standards, but the safety of your cryptos begins with you. A great way of ensuring that your funds are secure is by getting an offline storage device for your coins. I’ve seen great reviews on two hardware wallets that I highly recommend; these are the Ledger Nano S and Trezor wallets.
After getting the wallet of your choice, keep your personal data such as passwords and secret words private; this will ensure that no one else gains access to your wallet even if you misplace it. Writing your password or PIN on open places or somewhere in your phone might not be a good idea; yes, it may be convenient for you, but it will be for the burglar too.

What method of purchasing XRP is considered to be the best?

The most secure and common way of acquiring Ripple is through buying Ethereum or Bitcoin from Coinbase or Coinmama, then transferring the same to Cryptmixer to use to exchange with Ripple.
This is because Ripple is currently not available for purchase by using fiat currencies.

What is the best trading platform for Ripple?

Ripple is available on a decent number of exchanges including Binance, Coinmama, Coinbase, Bittrex, Cryptmixer, and more. However, among the stated ones, I have found Cryptmixer to be more secure and easier to use while it also offers the best trading rates and fees.

The Bottom Line

As we conclude, you now have some of the best choices when it comes to the exchange to acquire Ripple coins. After buying your XRP coins, store them offline on a secure device due to the risk of being faced by threats such as hacking or system failures.
If you’re serious about making cryptocurrency your investment vehicle in the long run, consider investing in a more lasting security solution such as a hardware storage device. You may not get them for a few pennies, but trust me when I say they are worth every last dime you spend on them.

Bob The Magic Custodian



Summary: Everyone knows that when you give your assets to someone else, they always keep them safe. If this is true for individuals, it is certainly true for businesses.
Custodians always tell the truth and manage funds properly. They won't have any interest in taking the assets as an exchange operator would. Auditors tell the truth and can't be misled. That's because organizations that are regulated are incapable of lying and don't make mistakes.

First, some background. Here is a summary of how custodians make us more secure:

Previously, we might give Alice our crypto assets to hold. There were risks:

But "no worries", Alice has a custodian named Bob. Bob is dressed in a nice suit. He knows some politicians. And he drives a Porsche. "So you have nothing to worry about!". And look at all the benefits we get:
See - all problems are solved! All we have to worry about now is:
It's pretty simple. Before we had to trust Alice. Now we only have to trust Alice, Bob, and all the ways in which they communicate. Just think of how much more secure we are!

"On top of that", Bob assures us, "we're using a special wallet structure". Bob shows Alice a diagram. "We've broken the balance up and store it in lots of smaller wallets. That way", he assures her, "a thief can't take it all at once". And he points to a historic case where a large sum was taken "because it was stored in a single wallet... how stupid".
"Very early on, we used to have all the crypto in one wallet", he said, "and then one Christmas a hacker came and took it all. We call him the Grinch. Now we individually wrap each crypto and stick it under a binary search tree. The Grinch has never been back since."

"As well", Bob continues, "even if someone were to get in, we've got insurance. It covers all thefts and even coercion, collusion, and misplaced keys - only subject to the policy terms and conditions." And with that, he pulls out a phone-book sized contract and slams it on the desk with a thud. "Yep", he continues, "we're paying top dollar for one of the best policies in the country!"
"Can I read it?' Alice asks. "Sure," Bob says, "just as soon as our legal team is done with it. They're almost through the first chapter." He pauses, then continues. "And can you believe that sales guy Mike? He has the same year Porsche as me. I mean, what are the odds?"

"Do you use multi-sig?", Alice asks. "Absolutely!" Bob replies. "All our engineers are fully trained in multi-sig. Whenever we want to set up a new wallet, we generate 2 separate keys in an air-gapped process and store them in this proprietary system here. Look, it even requires the biometric signature from one of our team members to initiate any withdrawal." He demonstrates by pressing his thumb into the display. "We use a third-party cloud validation API to match the thumbprint and authorize each withdrawal. The keys are also backed up daily to an off-site third-party."
"Wow that's really impressive," Alice says, "but what if we need access for a withdrawal outside of office hours?" "Well that's no issue", Bob says, "just send us an email, call, or text message and we always have someone on staff to help out. Just another part of our strong commitment to all our customers!"

"What about Proof of Reserve?", Alice asks. "Of course", Bob replies, "though rather than publish any blockchain addresses or signed transaction, for privacy we just do a SHA256 refactoring of the inverse hash modulus for each UTXO nonce and combine the smart contract coefficient consensus in our hyperledger lightning node. But it's really simple to use." He pushes a button and a large green checkmark appears on a screen. "See - the algorithm ran through and reserves are proven."
"Wow", Alice says, "you really know your stuff! And that is easy to use! What about fiat balances?" "Yeah, we have an auditor too", Bob replies, "Been using him for a long time so we have quite a strong relationship going! We have special books we give him every year and he's very efficient! Checks the fiat, crypto, and everything all at once!"

"We used to have a nice offline multi-sig setup we've been using without issue for the past 5 years, but I think we'll move all our funds over to your facility," Alice says. "Awesome", Bob replies, "Thanks so much! This is perfect timing too - my Porsche got a dent on it this morning. We have the paperwork right over here." "Great!", Alice replies.
And with that, Alice gets out her pen and Bob gets the contract. "Don't worry", he says, "you can take your crypto-assets back anytime you like - just subject to our cancellation policy. Our annual management fees are also super low and we don't adjust them often".

How many holes have to exist for your funds to get stolen?
Just one.

Why are we taking a powerful offline multi-sig setup, widely used globally in hundreds of different/lacking regulatory environments with 0 breaches to date, and circumventing it by a demonstrably weak third party layer? And paying a great expense to do so?
If you go through the list of breaches in the past 2 years to highly credible organizations, you go through the list of major corporate frauds (only the ones we know about), you go through the list of all the times platforms have lost funds, you go through the list of times and ways that people have lost their crypto from identity theft, hot wallet exploits, extortion, etc... and then you go through this custodian with a fine-tooth comb and truly believe they have value to add far beyond what you could, sticking your funds in a wallet (or set of wallets) they control exclusively is the absolute worst possible way to take advantage of that security.

The best way to add security for crypto-assets is to make a stronger multi-sig. With one custodian, what you are doing is giving them your cryptocurrency and hoping they're honest, competent, and flawlessly secure. It's no different than storing it on a really secure exchange. Maybe the insurance will cover you. Didn't work for Bitpay in 2015. Didn't work for Yapizon in 2017. Insurance has never paid a claim in the entire history of cryptocurrency. But maybe you'll get lucky. Maybe your exact scenario will buck the trend and be what they're willing to cover. After the large deductible and hopefully without a long and expensive court battle.

And you want to advertise this increase in risk, the lapse of judgement, an accident waiting to happen, as though it's some kind of benefit to customers ("Free institutional-grade storage for your digital assets.")? And then some people are writing to the OSC that custodians should be mandatory for all funds on every exchange platform? That this somehow will make Canadians as a whole more secure or better protected compared with standard air-gapped multi-sig? On what planet?

Most of the problems in Canada stemmed from one thing - a lack of transparency. If Canadians had known what a joke Quadriga was - it wouldn't have grown to lose $400m from hard-working Canadians from coast to coast to coast. And Gerald Cotten would be in jail, not wherever he is now (at best, rotting peacefully). EZ-BTC and mister Dave Smilie would have been a tiny little scam to his friends, not a multi-million dollar fraud. Einstein would have got their act together or been shut down BEFORE losing millions and millions more in people's funds generously donated to criminals. MapleChange wouldn't have even been a thing. And maybe we'd know a little more about CoinTradeNewNote - like how much was lost in there. Almost all of the major losses with cryptocurrency exchanges involve deception with unbacked funds.
So it's great to see transparency reports from BitBuy and ShakePay where someone independently verified the backing. The only thing we don't have is:
It's not complicated to validate cryptocurrency assets. They need to exist, they need to be spendable, and they need to cover the total balances. There are plenty of credible people and firms across the country that have the capacity to reasonably perform this validation. Having more frequent checks by different, independent, parties who publish transparent reports is far more valuable than an annual check by a single "more credible/official" party who does the exact same basic checks and may or may not publish anything. Here's an example set of requirements that could be mandated:
There are ways to structure audits such that neither crypto assets nor customer information are ever put at risk, and both can still be properly validated and publicly verifiable. There are also ways to structure audits such that they are completely reasonable for small platforms and don't inhibit innovation in any way. By making the process as reasonable as possible, we can completely eliminate any reason/excuse that an honest platform would have for not being audited. That is arguable far more important than any incremental improvement we might get from mandating "the best of the best" accountants. Right now we have nothing mandated and tons of Canadians using offshore exchanges with no oversight whatsoever.

Transparency does not prove crypto assets are safe. CoinTradeNewNote, Flexcoin ($600k), and Canadian Bitcoins ($100k) are examples where crypto-assets were breached from platforms in Canada. All of them were online wallets and used no multi-sig as far as any records show. This is consistent with what we see globally - air-gapped multi-sig wallets have an impeccable record, while other schemes tend to suffer breach after breach. We don't actually know how much CoinTrader lost because there was no visibility. Rather than publishing details of what happened, the co-founder of CoinTrader silently moved on to found another platform - the "most trusted way to buy and sell crypto" - a site that has no information whatsoever (that I could find) on the storage practices and a FAQ advising that “[t]rading cryptocurrency is completely safe” and that having your own wallet is “entirely up to you! You can certainly keep cryptocurrency, or fiat, or both, on the app.” Doesn't sound like much was learned here, which is really sad to see.
It's not that complicated or unreasonable to set up a proper hardware wallet. Multi-sig can be learned in a single course. Something the equivalent complexity of a driver's license test could prevent all the cold storage exploits we've seen to date - even globally. Platform operators have a key advantage in detecting and preventing fraud - they know their customers far better than any custodian ever would. The best job that custodians can do is to find high integrity individuals and train them to form even better wallet signatories. Rather than mandating that all platforms expose themselves to arbitrary third party risks, regulations should center around ensuring that all signatories are background-checked, properly trained, and using proper procedures. We also need to make sure that signatories are empowered with rights and responsibilities to reject and report fraud. They need to know that they can safely challenge and delay a transaction - even if it turns out they made a mistake. We need to have an environment where mistakes are brought to the surface and dealt with. Not one where firms and people feel the need to hide what happened. In addition to a knowledge-based test, an auditor can privately interview each signatory to make sure they're not in coercive situations, and we should make sure they can freely and anonymously report any issues without threat of retaliation.
A proper multi-sig has each signature held by a separate person and is governed by policies and mutual decisions instead of a hierarchy. It includes at least one redundant signature. For best results, 3of4, 3of5, 3of6, 4of5, 4of6, 4of7, 5of6, or 5of7.

History has demonstrated over and over again the risk of hot wallets even to highly credible organizations. Nonetheless, many platforms have hot wallets for convenience. While such losses are generally compensated by platforms without issue (for example Poloniex, Bitstamp, Bitfinex, Gatecoin, Coincheck, Bithumb, Zaif, CoinBene, Binance, Bitrue, Bitpoint, Upbit, VinDAX, and now KuCoin), the public tends to focus more on cases that didn't end well. Regardless of what systems are employed, there is always some level of risk. For that reason, most members of the public would prefer to see third party insurance.
Rather than trying to convince third party profit-seekers to provide comprehensive insurance and then relying on an expensive and slow legal system to enforce against whatever legal loopholes they manage to find each and every time something goes wrong, insurance could be run through multiple exchange operators and regulators, with the shared interest of having a reputable industry, keeping costs down, and taking care of Canadians. For example, a 4 of 7 multi-sig insurance fund held between 5 independent exchange operators and 2 regulatory bodies. All Canadian exchanges could pay premiums at a set rate based on their needed coverage, with a higher price paid for hot wallet coverage (anything not an air-gapped multi-sig cold wallet). Such a model would be much cheaper to manage, offer better coverage, and be much more reliable to payout when needed. The kind of coverage you could have under this model is unheard of. You could even create something like the CDIC to protect Canadians who get their trading accounts hacked if they can sufficiently prove the loss is legitimate. In cases of fraud, gross negligence, or insolvency, the fund can be used to pay affected users directly (utilizing the last transparent balance report in the worst case), something which private insurance would never touch. While it's recommended to have official policies for coverage, a model where members vote would fully cover edge cases. (Could be similar to the Supreme Court where justices vote based on case law.)
Such a model could fully protect all Canadians across all platforms. You can have a fiat coverage governed by legal agreements, and crypto-asset coverage governed by both multi-sig and legal agreements. It could be practical, affordable, and inclusive.

Now, we are at a crossroads. We can happily give up our freedom, our innovation, and our money. We can pay hefty expenses to auditors, lawyers, and regulators year after year (and make no mistake - this cost will grow to many millions or even billions as the industry grows - and it will be borne by all Canadians on every platform because platforms are not going to eat up these costs at a loss). We can make it nearly impossible for any new platform to enter the marketplace, forcing Canadians to use the same stagnant platforms year after year. We can centralize and consolidate the entire industry into 2 or 3 big players and have everyone else fail (possibly to heavy losses of users of those platforms). And when a flawed security model doesn't work and gets breached, we can make it even more complicated with even more people in suits making big money doing the job that blockchain was supposed to do in the first place. We can build a system which is so intertwined and dependent on big government, traditional finance, and central bankers that it's future depends entirely on that of the fiat system, of fractional banking, and of government bail-outs. If we choose this path, as history has shown us over and over again, we can not go back, save for revolution. Our children and grandchildren will still be paying the consequences of what we decided today.
Or, we can find solutions that work. We can maintain an open and innovative environment while making the adjustments we need to make to fully protect Canadian investors and cryptocurrency users, giving easy and affordable access to cryptocurrency for all Canadians on the platform of their choice, and creating an environment in which entrepreneurs and problem solvers can bring those solutions forward easily. None of the above precludes innovation in any way, or adds any unreasonable cost - and these three policies would demonstrably eliminate or resolve all 109 historic cases as studied here - that's every single case researched so far going back to 2011. It includes every loss that was studied so far not just in Canada but globally as well.
Unfortunately, finding answers is the least challenging part. Far more challenging is to get platform operators and regulators to agree on anything. My last post got no response whatsoever, and while the OSC has told me they're happy for industry feedback, I believe my opinion alone is fairly meaningless. This takes the whole community working together to solve. So please let me know your thoughts. Please take the time to upvote and share this with people. Please - let's get this solved and not leave it up to other people to do.

Recover Stolen Bitcoin and Cryptocurrency

Recover Stolen Bitcoin and Cryptocurrency

Recover Stolen Bitcoin and Cryptocurrency
Cryptocurrencies are a high priority target for cybercriminals. Whether targeting your wallet directly or hacking the exchanges once cybercriminals have access to your currency you need to act fast! You can also recover money lost to binary options.
Lost Bitcoin? Stolen Cryptocurrency? Hacked virtual currency account - Follow these steps now!
  1. Report to appropriate authorities - Report the case to the appropriate authorities, for them to be able to have it looked into.
  2. Change your login details - If you are still able to login to your account then follow the normal procedure to reset your password and other security information. Enable two-factor authentication. This should lock the criminal out of the account.
  3. Notify the exchange/provider - If you have purchased or are storing your currency with a service provider then let them know about the breach and the fraudulent transactions. They may be able to retain some information about the transaction that could come in useful in an investigation.
Will I Recover my Stolen Bitcoin?
Once your virtual currency has been stolen it is incredibly unlikely that you will be able to recover it. In theory, it’s possible to track your stolen bitcoin by monitoring the blockchain – in practice, however, this is made difficult by both the anonymous nature of the currency and the fact that the thief will most likely use a bitcoin exchange to trade the currency for normal cash straight away. However, money does leave a trail and you may be able to follow it to the identity of the criminal.
How to Recover Stolen Bitcoin and Cryptocurrency
  1. Check your devices for malware - It is worth considering that a malicious software infection may have led to the hacker accessing your currency. Scan the devices you use to handle your currency and make sure they are clean. You can follow our guide on checking for and removing malware here.
  2. Call your bank - If the transaction had related costs that hit your bank accounts - such as transaction fees or deposits - then contact your bank immediately and let them know it is an unauthorized/fraudulent transaction.
  3. Follow the money - You can follow the transactions of the wallet address that your funds were scammed into. If you notice the scammer attempt to transfer funds from the wallet to cryptocurrency exchanges to sell for fiat currency, report to the relevant exchanges immediately. An opportunity to catch the scammer is to follow the money trail through blockchain explorers and trace your lost funds. You can use browser-based blockchain exploring software such as https://blockexplorer.com to ‘follow’ the payment through to an end bitcoin address. Once you have this address you can check whether the owners of the end address(es) appear on http://bitcoinwhoswho.com/. In order to trade crypto to regular money on most popular exchanges, the thief would need to submit KYC (Know Your Customer) information, such as names, addresses, and ID information. Contacting the exchanges can potentially help you to track down the scammer’s identity. This is another reason why it is important for you to file a police report as soon as the incident has taken place.
  4. Hire a Verified Recovery Expert - If you are willing to pay a decent amount for the return of your funds there are websites where you can post a bounty. Experienced blockchain searchers will investigate the theft and see if they can recover the funds for a price. Check out the list of verified recovery experts.
How to Avoid your Cryptocurrency Being Stolen in Future
  • Don’t talk publicly about owning virtual currency - If it is easy to work out that you own a cryptocurrency from your social media activity then you are much more likely to be a target.
  • Use multi-factor authentication - Ensure that you have multi-factor authentication enabled. Use an authenticator app rather than the SMS option. If the option to disable SMS authentication exists then do it.
  • Use a new email address and complex password to set up the account - A new, clean email address that you will only use for the virtual currency account is best. This reduces the chance of you being targeted via your email account.
  • Use a ‘cold-wallet’ - Keep your cryptocurrency off the internet, in a "cold wallet." "Cold wallet" is not a brand, it's a concept of storing bitcoins offline (not connected to the internet) so that it reduces the opportunities for hackers to steal via online techniques.
  • Spread your investments across exchanges - A number of exchanges have been breached. Spread your investments across exchanges to minimize the impact.
  • Get secure - Take time to improve your general online security. Use sites like getting Safe Online and Cyber Aware to understand what good security looks like and make changes. I was personally able to recover my lost bitcoin with the help of Express Recovery Pro – [email protected]

RIP HAL FINNEY "His last post on a BTC Forum"

I thought I'd write about the last four years, an eventful time for Bitcoin and me.
For those who don't know me, I'm Hal Finney. I got my start in crypto working on an early version of PGP, working closely with Phil Zimmermann. When Phil decided to start PGP Corporation, I was one of the first hires. I would work on PGP until my retirement. At the same time, I got involved with the Cypherpunks. I ran the first cryptographically based anonymous remailer, among other activities.
Fast forward to late 2008 and the announcement of Bitcoin. I've noticed that cryptographic graybeards (I was in my mid 50's) tend to get cynical. I was more idealistic; I have always loved crypto, the mystery and the paradox of it.
When Satoshi announced Bitcoin on the cryptography mailing list, he got a skeptical reception at best. Cryptographers have seen too many grand schemes by clueless noobs. They tend to have a knee jerk reaction.
I was more positive. I had long been interested in cryptographic payment schemes. Plus I was lucky enough to meet and extensively correspond with both Wei Dai and Nick Szabo, generally acknowledged to have created ideas that would be realized with Bitcoin. I had made an attempt to create my own proof of work based currency, called RPOW. So I found Bitcoin facinating.
When Satoshi announced the first release of the software, I grabbed it right away. I think I was the first person besides Satoshi to run bitcoin. I mined block 70-something, and I was the recipient of the first bitcoin transaction, when Satoshi sent ten coins to me as a test. I carried on an email conversation with Satoshi over the next few days, mostly me reporting bugs and him fixing them.
Today, Satoshi's true identity has become a mystery. But at the time, I thought I was dealing with a young man of Japanese ancestry who was very smart and sincere. I've had the good fortune to know many brilliant people over the course of my life, so I recognize the signs.
After a few days, bitcoin was running pretty stably, so I left it running. Those were the days when difficulty was 1, and you could find blocks with a CPU, not even a GPU. I mined several blocks over the next days. But I turned it off because it made my computer run hot, and the fan noise bothered me. In retrospect, I wish I had kept it up longer, but on the other hand I was extraordinarily lucky to be there at the beginning. It's one of those glass half full half empty things.
The next I heard of Bitcoin was late 2010, when I was surprised to find that it was not only still going, bitcoins actually had monetary value. I dusted off my old wallet, and was relieved to discover that my bitcoins were still there. As the price climbed up to real money, I transferred the coins into an offline wallet, where hopefully they'll be worth something to my heirs.
Speaking of heirs, I got a surprise in 2009, when I was suddenly diagnosed with a fatal disease. I was in the best shape of my life at the start of that year, I'd lost a lot of weight and taken up distance running. I'd run several half marathons, and I was starting to train for a full marathon. I worked my way up to 20+ mile runs, and I thought I was all set. That's when everything went wrong.
My body began to fail. I slurred my speech, lost strength in my hands, and my legs were slow to recover. In August, 2009, I was given the diagnosis of ALS, also called Lou Gehrig's disease, after the famous baseball player who got it.
ALS is a disease that kills moter neurons, which carry signals from the brain to the muscles. It causes first weakness, then gradually increasing paralysis. It is usually fatal in 2 to 5 years. My symptoms were mild at first and I continued to work, but fatigue and voice problems forced me to retire in early 2011. Since then the disease has continued its inexorable progression.
Today, I am essentially paralyzed. I am fed through a tube, and my breathing is assisted through another tube. I operate the computer using a commercial eyetracker system. It also has a speech synthesizer, so this is my voice now. I spend all day in my power wheelchair. I worked up an interface using an arduino so that I can adjust my wheelchair's position using my eyes.
It has been an adjustment, but my life is not too bad. I can still read, listen to music, and watch TV and movies. I recently discovered that I can even write code. It's very slow, probably 50 times slower than I was before. But I still love programming and it gives me goals. Currently I'm working on something Mike Hearn suggested, using the security features of modern processors, designed to support "Trusted Computing", to harden Bitcoin wallets. It's almost ready to release. I just have to do the documentation.
And of course the price gyrations of bitcoins are entertaining to me. I have skin in the game. But I came by my bitcoins through luck, with little credit to me. I lived through the crash of 2011. So I've seen it before. Easy come, easy go.
That's my story. I'm pretty lucky overall. Even with the ALS, my life is very satisfying. But my life expectancy is limited. Those discussions about inheriting your bitcoins are of more than academic interest. My bitcoins are stored in our safe deposit box, and my son and daughter are tech savvy. I think they're safe enough. I'm comfortable with my legacy.

From 10000 to 10 Million: Coin Circle KOL Happy Shares the Road of Gold Mining in China

From 10000 to 10 Million: Coin Circle KOL Happy Shares the Road of Gold Mining in China
On July 27,2020, Bitcoin soared from US $9900 to US $11400, a 15% increase in a single day, opening the first round of global cryptocurrency market outbreak after the epidemic.Since then, different currencies have been soaring in turn every day.A few days ago, I attended a private gathering of cryptocurrency circle in Silicon Valley, and got to know a veteran of currency circle named XX.XX is a China expert and an early investor of TRX, OMG and EOS. It started from $10000 and now has a value of more than $10 million. It is called China bitbutcher in a small circle.The author and XX talked about a lot of dry goods, now sorted out to share with you, interested can add my telegraph group(https://0.plus/bpopaha)Discuss it together.The following is the account in XX’s own words.
Firstly, you need to understand the market.
Some people call me China Bitbutcher. In fact, there are many people who make more money than me in the Chinese market. Although the projects invested are different, they all have one thing in common, that is, they all have a better understanding of the Chinese market. At least you have to install a Wechat. You see, I have added many groups of Chinese investors to collect information and study their investment characteristics. For example, this expression pack is very representative.

https://preview.redd.it/lf8vonlf5ft51.png?width=554&format=png&auto=webp&s=d7821b57d41984254f8fc6643a5f084565db8749
"show-hand" here is the transliteration of show hand, which means that you can bet all your cash on a single coin. If you only bet on one coin, you will have either heaven or hell.Whenever a KOL starts to shout for orders, the retail investors in the community will rush to get into the gold and shout the slogan of "show-hand". The lucky ones who get into the gold earlier will get several times or even dozens of times (or higher) return on investment.
Similar to the "Beat Generation" born after World War II in the United States, today's young people in China are called "post-90s" and "post-00s". Although they don't have to worry about food and drink, their limited income is far behind the increase in urban house prices and living costs. Houses and cars are the necessary conditions for young Chinese men to marry their wives.As a result, these young people tend to be very aggressive in investment, and there are many people eager to make tens of thousands of dollars with thousands of dollars.At present, there are millions of investors in China's currency circle, which is equivalent to the total population of some small European countries. Behind this, there are tens of millions of stock investors who will turn to coin circle people at any time. Since the popularity of ICO in 2017, China has produced dozens of hundreds or even thousands of times projects such as Neo, TRX, ONT, etc., and tens of billions of dollars of funds have been taken out and deposited from the pockets of investors in the currency circle. At the same time, there are also a large number of gold miners (most of them are foreigners) who have absorbed a lot of money from China through ICO and obtained wealth freedom. Among them, EOS is a typical example. The financing time is as long as one year, and the financing scale is more than 2 billion US dollars, of which a large part is paid by Chinese young people. There is also a well-known KOL in China, who has been crazy about EOS, even calling out the slogan of "three waves of fighting to 1000 yuan (Note: 1000 yuan is equivalent to 143 US dollars, currently EOS is worth 3 dollars). However, such a crazy KOL still has the support of hundreds of thousands of fans. Fortunately, with so many fanatics, the EOS I held in the early stage could be safely and gradually shipped, with a comprehensive yield of 553%. It's not too much to say that it's collecting money on the ground. So if you take the same money and gamble with the gentlemen on Wall Street, you'd better take the same money to China’s currency circle market. By the way, there was also a big man in the currency circle in China who said that these retail investors were "idiot", "stupid people, lots of money, come quickly". I didn't believe it. However, at the end of 2017, I heard from my Chinese friends that I invested in a project called TRX. I only invested $5000, and finally I withdrew 100 times. 5000 US dollars turned into 500000 US dollars. Since then, I have fallen in love with this magic market.
Secondly, we should see the situation clearly.
A leader of China's democratic revolution once said a sentence that I like very much, which is called "the general trend of the world, the one who goes along will prosper, and the one who goes against will die." So before you pay, ask yourself a question: do you think the bull market has opened? Or is the bull market in the middle? This needs your own judgment, conform to the general trend to make money. In my opinion, at the present stage, two thirds of 2020 has passed. In the past eight months, the global epidemic broke out, the economy went down, the US stock market failed, the Olympic Games were postponed, and Bitcoin plummeted to 3800usdt.Under this undercurrent, hot money is irresistible, especially the savings of Chinese currency circle investors in the long bear market, which urgently needs an investment export. On the surface, this bull market is led by Ethereum, but in fact it is the result of a combination of multiple factors. One of the key points is to invest in customers' wallets. With Bitcoin starting on July 21, the current high level of 12000 or so, most of the mainstream currencies in the market have completed the round of rise. Meanwhile, the defi plate is extremely hot, and the future market will continue to be bullish. Judging the situation is the basic logic of our investment. If this does not hold up, there is no need to look down.
Thirdly, choose potential currencies.
If you also agree that the bull market will continue, then you should take advantage of this wave of heat, ambush some hot currencies in advance, and then wait for the market makers to stir up the market and plate, attract a large number of retail investors to follow suit, so as to easily make money in the market. At present, it is obvious that the market has entered the second typical stage: bitcoin trading horizontally and counterfeit currency rising in turn. Almost every day comes the news that the counterfeit currency of XX is about to soar, and then investors who build their positions ahead of time are beaming with joy to show their income map in the major communities.
Please note that! At this time, most of the unqualified investors are following the trend and buying without their own opinions. It is true that some people have made a lot of money, but the risks have multiplied. Because while they are making money, they are also carrying sedan chairs for the makers. But a small number of "smart people" don't think so. They firmly believe that the safest way is to make money within their scope. One of the important ideas is to explore the underrated high-quality projects that have not yet started to rise in the bull market, complete the warehouse building at the low level, and get the early hundred times chips.
Fourth, how to find a hundred times currency.
As we all know, 100 times coin has the following characteristics: it has a perfect business model and pass card model, has its own application and ecology, and has a group of loyal users and community consensus. This is the fundamental reason why I found TRX, OMG, ONT and other currencies. There is an outstanding businessman named Jack Ma in China. He put forward a concept called "small is beautiful", which means that the best investment target is a project with small scale and high marginal profit. Just in the past two days, I downloaded an investment advisory app called coin bubble through China's wechat group, and also sent a token. I think it is small and beautiful according to my own definition.

According to the official introduction, the coin bubble is a mobile terminal entrance for digital financial investors. It is committed to creating a rich, interesting and practical digital financial investment consultant ecosystem, helping new users of the digital financial investment circle to quickly integrate into the circle and culture, improve their investment skills and obtain better investment returns. The goal of currency bubble is to become the first stop for traditional financial investors to enter the digital financial world and the first entrance for incremental users and incremental funds. The concept is quite grand, but in a word, the team has made a consultant app for coin circle investment and built an active community of crypto asset enthusiasts. Through the mode of knowledge payment or commission, KOL at the head of the coin circle helps their fans to purchase crypto assets and derivatives with zero threshold, and obtain commission income from it.

Different from some projects on the market that often claim to be hundreds of thousands of users and start to issue money in the air stage, the money bubble has been done as a traditional Internet project from the beginning. The team itself is not short of money, and has not raised a lot of money in the initial stage. Instead, it only focuses on the perspective of resource exchange from the perspective of Genesis fund, alpha-coin fund and Continue Capital and other cryptocurrency capital parties symbolically took some start-up funds in order to better utilize the latter's extensive network resources in the currency circle. According to a friend who has a good relationship with the core team, the management of the currency bubble is extremely low-key, and rarely appears in front of the currency circle media. The team has always believed in the principle of product first, and has little interest in marketing. Just as soon as the app 1.0 version was launched, it caused a widespread sensation in the currency circle, and even was immediately plagiarized at pixel level by another well-known giant app two weeks later. But the team just said in the internal meeting, copy it, see whether you copy fast or we innovate fast. As a result, when app2.0 was released, the coin recommendation function was once again popular, absorbing countless powder, and it was still copied by several friends. However, this kind of plagiarism can not last for a long time, because the money bubble depends not only on the function innovation, but also on the community reputation. The Internet has such Matthew effect, and the head app is always strong.
At present, the coin bubble has initially established a product matrix of currency recommendation, spot strategy, contract strategy and communication community. Investors, KOL, exchanges and project parties in the currency circle can take what they need and get the resources they want. At present, money bubble has been the first place in the investment advisory track by relying on natural flow and word-of-mouth propaganda. Many of the original friends who only relied on plagiarism have disappeared. At present, there are about 3000 KOLs with different levels in the currency bubble, which continuously release spot currency, contract strategy and potential currency on app. Online, hundreds of thousands of users can easily find KOL with high success rate and stable yield through the currency bubble platform to carry out documentary operation to obtain profits. Offline, the coin bubble has dozens of official wechat groups and hundreds of alliance groups, radiating millions of users in the currency circle. Currency bubble has become the first professional community in China's domestic currency circle.

Money bubble online community currency bubble wechat community
In order to better integrate and match the resources in the ecosystem, coin bubble launched token BPOP with the same name in a low-key manner in 19 years, but it has not been vigorously promoted. This is also in line with the team's low-key temperament of not lacking money, not promoting and only making products with heart. According to internal information, BPOP token will be used for the following purposes:
First, you can use BPOP to subscribe to KOL's trading strategy. Previously, in order to comply in China, BPOP has been using French currency to settle Commission. However, the team may have considered the subsequent global promotion, and it is time to introduce ecological token for internal settlement. The good news is that the English version of coin bubble was launched in early September, which will better serve the global English speaking users in North America and Europe. At the same time, the project side also said that it would launch multi language versions such as Japanese version, Korean version and Latin version as soon as possible, so as to provide accurate investment advisory services for users in more regions of the world.
Secondly, BPOP can be used to offset the service charge of the platform.This seems to be consistent with the strategy of the traditional exchange and the traditional investment consulting company, but in fact, the Commission is charged only when the strategy is profitable. This is totally different from the traditional one. It is a killing strategy created from the perspective of investors in the currency circle. As we know, the vast majority of the profits of exchanges and consulting companies come from the handling fees for ensuring the collection of goods during drought and flood, especially for futures contracts, which are extremely high. This small fee hides the ambition of the currency bubble to subvert the status quo of the industry. Now there is a popular word called dimension reduction strike. It is the Internet that kills physical stores, and takeaway is used to kill instant noodles. Is it possible that the person who kills the exchange is such a latecomer?
Thirdly, BPOP can be used for position dividend. As mentioned above, the money bubble is set up according to the traditional Internet companies, and has its own stable source of income. Besides the platform Commission, a large part of it comes from the realization of traffic, that is, advertising revenue. Money bubble has served many star customers, such as OKEX, Bybit, MXC, famous project parties such as STPT, AKRO, DOS, ARPA, etc., and has reached hundreds of customers. Relying on its own flow advantages, the coin bubble provides accurate diversion and product promotion services for customers, matches high-quality investors in the currency circle for high-quality project parties and exchanges, and achieves a win-win situation. The subsequent position is equivalent to holding currency bubble stock, which will continue to enjoy the income and dividend of currency bubble.
According to informed sources, BPOP will develop new products in combination with the current defi hot spots, and BPOP will also be the only value medium in the product ecology of defi, which means that the higher the demand for products, the stronger the price support of BPOP.
- BPSwap
BPSwap is an asset exchange platform, which can be used for token exchange of any public chain agreement. In the initial stage of the product, BPOP will be used as the main exchange target, i.e. eth / BPOP, TRX / BPOP and other transaction pairs. In the later stage, transactions between different currencies and flash exchange functions will be gradually opened;
When a general investor subscribes to KOL's portfolio with BPOP, he / she can use BPSwap for trading exchange, and can also obtain income by providing transaction liquidity, which can not only quickly buy "wealth password" but also obtain additional income by using "wealth password";
The main functions of BPSwap are as follows:
1)Provide various platform data. Such as liquidity pool data, convertible currency pairs, exchange currency pair liquidity and transaction volume data;
Exchange mechanism of transaction currency. In the initial stage, erc-20 or trc-20 will be opened to exchange currency pairs for BPOP transactions. Any user can view KOL recommended currency on BPOP platform and conduct transaction exchange directly;
2)Liquidity pool reward and new liquidity token. Any user can provide liquidity for different trading currency pairs, increase or remove assets in the liquidity pool. At the same time, the platform will issue a new liquidity token bpop-lp to reward users who provide liquidity for trading currency pairs. Bpop-lp can be exchanged with BPOP / USDT / eth;
3)Flash cash function. Quick exchange of small assets.
In a word, BPSwap can make the users of currency bubble realize all kinds of "one-step" needs, from buying currency, to checking and recommending currency, to asset transaction and exchange, etc., so as to realize the closed-loop use of digital currency. As the only value medium of BPSwap, BPOP will be used by more and more users with the maturity of products, and the price will rise.
Finally, BPOP will also realize the interesting functions of internal users such as reward and props purchase, which may be related to the next blockbuster version. I don't know the details, so I won't make a wild guess.
The above is basically from the product, operation and technical aspects of the project analysis, but these alone are not enough, when we choose the investment target, we also need to carefully analyze the token situation, in order to draw a more accurate conclusion.These analyses are boring, but they are often critical. The reason is exactly the same when we analyze other currencies according to the method I said.
The reason why bitcoin has become the favorite of investors is that it can not be issued more shares and has the characteristics of unlimited deflation. Although BPOP cannot be dug out, its deflation is more fierce and fierce. I can easily find out that the current circulation of BPOP is extremely limited after a large number of lock ups and multiple destruction of BPOP by combining the announcement issued by the currency bubble and the data on the chain. The currency distribution of BPOP is shown in the figure. The orange part is the market circulation volume, accounting for 10%.The other blue parts are those in lock / destroyed / to be destroyed.
Currency bubble contract address: 0x0452aed878805514e28fb5bd0b56bef92176e32a
As can be seen from the figure, the total amount of BPOP is 1 billion. Among them, the foundation has actively destroyed 500 million, ecological destruction has reached 100 million, team lock up 200 million, private placement has not been issued and destroyed by 42.4 million. The remaining cornerstone investment is 100 million and the market is 57.6 million. At present, there is only 157.6 million circulation in the market. According to the official announcement, the government has been using the business profits to buy back from the secondary market. At present, the government has successively bought back about 60 million, and the real circulation in the market is only about 97 million tokens.
In addition, the project side's goal is to continue to buy back to 147.6 million and then destroy all the tokens, and all the tokens will be deflated to 10 million. According to the current real circulation of 97 million, the current CBX.ONE Its latest trading price is 0.005usdt, and its circulation market value is about 485000u. Compared with its current user volume and business volume, it is in a seriously underestimated state, and there is a huge space for imagination in the future. At present, the price is at a historical low price, which conforms to all my definitions of small and beautiful.
To sum up, BPOP meets all the characteristics of this bull market
- The business model, application and ecology are complete, and a large number of landing products are used by users;
- The market value of project token is small, but the project investment institutions are strong;
- The project team has deep experience in the blockchain industry and is keen on doing practical things.
- The direction of the project is in line with the hot spots of the current bull market.
There is a well-known saying in China's retail circle, "hold on, the team is working." On the one hand, it means that the team only focuses on the products and does not care about the price performance of the secondary market; on the other hand, it means that the project team is really pushing the whole product forward and the price has strong support. However, as long as there are specific landing products and a large number of users use them, the currency price will naturally attract other hot money to come in and raise the price. After all, the secondary market is just a capital game, and the coin bubble project meets this condition. The products are developed in an orderly way, and the market value is still so small. It is very easy for BPOP to rise several times or dozens of times in this bull market.
At present, BPOP passes can be found in the decentralized exchange uniswap (search BPOP or contract address: 0x0452aed878805514e28fb5bd0b56bef92176e32a) and the centralized exchange Dubai compliance exchange cbx.com Trading. Those who are interested can learn about it by themselves. Of course, before buying, you can also go to its official website(http://www.bpop.io)Download the app to experience it. By the way, I tried to recharge 1000 usdt, and now I have made more than 300 usdt. Of course, some secondary pages still have a lot of Chinese, which is a little difficult to watch. It is said that an optimized version of the English version will be released soon, and everyone can experience it at that time.
Finally, I would like to remind you that although the money in China's currency circle is relatively easy to earn, it is also a high-risk investment variety. Before you enter this market, please be sure to follow the above-mentioned method to deeply understand the Chinese market and analyze the currency you like in detail. If you have any questions, please feel free to communicate with me.
