Vanillacoin - a superior form of cryptocurrency. Vanillacoin is not a clone of Bitcoin or Peercoin, it was engineered from the ground up and is designed to be innovative and forward-thinking. It prevents eavesdropping and censorship and has security in mind. It also promotes decentralized and energy efficient network transactions at sub second speeds.
At current state-of-the-art Bitcoin ASIC miner efficiency, the network hash rate will increase until it hits around 1243 PH/s (1,243,360 TH/s) (difficulty 168 billion)
We know the efficiency of the newest ASICs. Miners will keep adding capacity until their margins are fairly low, say 20% more than their electricity costs. Bitfury's new miner only uses 0.8J/GH (here it uses 1J/GH, but they're underclocking the chips in final devices to reach 0.8J/GH). With an electricity price of $0.1/kWh, that means miners want to make at least $0.12 per kWh spent. 0.8J / GH 1 kWh = 3600000 J So mining for one day at 1 GH/s at 0.8J / GH uses 3600*24*0.8J: 69120J / GH/s for 1 day which, in kWh, is: 0.0192 kWh / GH/s for 1 day so to spend 1 kWh per day we can mine at 1/0.0192 GH/s for 1 day: 1 kWh / 52 GH/s for 1 day Mining at 52 GH/s for 1 day currently makes $78.53 (at the next difficulty of 25.7M). So in order for it to only produce $0.12 (which miners are willing to go down to), network hash rate would have to increase by a factor of 78.53/0.012 = 6544 So at current ASIC efficiency (using Bitfury as an example), the difficulty will increase to 168 billion (168,000M) until miners' margins are 20% (at current BTC prices). This will bring the network hashrate up to 1243 PH/s (1,243,360 TH/s).
Unreal, as the price of Bitcoin drops below $400; the global hash rate is set to create another 20% difficulty increase... Something's gotta give.
On one hand miners will make 20% less in about a week, while the price of Bitcoin has now dropped below $400 a coin. Combine them both and mining profits just shrank dramatically. How long can this trend continue?
Is this sentence accurate? "In order to continue earning the same number of bitcoins, your hash rate must increase at the rate of the difficulty rise"
As above. Basically, my understanding is that if I have, say, 100 GH/s of mining equipment, and the difficulty rises tomorrow by 10%, then I will require mining equipment of 110 GH/s to continue earning the same amount of bitcoins (variance and reward-halvings notwithstanding...)
Profitability Calculations with regard to increasing difficulty.
Hello. I've been looking for profitability calculator that takes into account increasing difficulty. I've found one that takes into account a daily increase in hashrate. I've also found one that takes into account a daily (or bi-monthly) increase in difficulty. Quick question before I continue -- Does an increase in difficulty correspond linearly with an increase in hashrate? Which one of those calculators (if correctly coded) would be more accurate? As I am a big fan of trust, but verify, I would like to build my own calculator to make sure that the online version I choose is correct. This may be overkill, but I have been tasked by my boss to complete a feasibility study of building a huge mining farm. Most calculators will only give a right now kind of answer to profitability. I need to be able to get year over year numbers that include the daily declining profitability. Thanks in advance. P.S. If any of you currently own or operate a big mining farm (3000+ ASICs) and have any advice, pointers, or lessons learned, I would love to hear them.
I have done my fair bit of research on bitcoin and how mining works and difficulty. Most people on different crypto reddit and blogs are indicating that mining is almost over for individuals and is only for corporations. I have an electricity rate of 0.0075$/kWh. And an investment of $100k. From what I have researched it could still be beneficial. While i could still just buy bitcoin, mining seems safer and could turn into a passive income. With the recent increase in difficulty that could prove that it's getting alot harder for day to day miners to keep at it. Any thoughts?
Stakenet (XSN) - A DEX with interchain capabilities (BTC-ETH), Huge Potential [Full Writeup]
Preface Full disclosure here; I am heavily invested in this. I have picked up some real gems from here and was only in the position to buy so much of this because of you guys so I thought it was time to give back. I only invest in Utility Coins. These are coins that actually DO something, and provide new/build upon the crypto infrastructure to work towards the end goal that Bitcoin itself set out to achieve(financial independence from the fiat banking system). This way, I avoid 99% of the scams in crypto that are functionless vapourware, and if you only invest in things that have strong fundamentals in the long term you are much more likely to make money. Introduction
Stakenet is a Lightning Network-ready open-source platform for decentralized applications with its native cryptocurrency – XSN. It is powered by a Proof of Stake blockchain with trustless cold staking and Masternodes. Its use case is to provide a highly secure cross-chain infrastructure for these decentralized applications, where individuals can easily operate with any blockchain simply by using Stakenet and its native currency XSN.
Ok... but what does it actually do and solve? The moonshot here is the DEX (Decentralised Exchange) that they are building. This is a lightning-network DEX with interchain capabilities. That means you could trade BTC directly for ETH; securely, instantly, cheaply and privately. Right now, most crypto is traded to and from Centralised Exchanges like Binance. To buy and sell on these exchanges, you have to send your crypto wallets on that exchange. That means the exchanges have your private keys, and they have control over your funds. When you use a centralised exchange, you are no longer in control of your assets, and depend on the trustworthiness of middlemen. We have in the past of course seen infamous exit scams by centralised exchanges like Mt. Gox. The alternative? Decentralised Exchanges. DEX's have no central authority and most importantly, your private keys(your crypto) never leavesYOUR possession and are never in anyone else's possession. So you can trade peer-to-peer without any of the drawbacks of Centralised Exchanges. The problem is that this technology has not been perfected yet, and the DEX's that we have available to us now are not providing cheap, private, quick trading on a decentralised medium because of their technological inadequacies. Take Uniswap for example. This DEX accounts for over 60% of all DEX volume and facilitates trading of ERC-20 tokens, over the Ethereum blockchain. The problem? Because of the huge amount of transaction that are occurring over the Ethereum network, this has lead to congestion(too many transaction for the network to handle at one time) so the fees have increased dramatically. Another big problem? It's only for Ethereum. You cant for example, Buy LINK with BTC. You must use ETH. The solution? Layer 2 protocols. These are layers built ON TOP of existing blockchains, that are designed to solve the transaction and scaling difficulties that crypto as a whole is facing today(and ultimately stopping mass adoption) The developers at Stakenet have seen the big picture, and have decided to implement the lightning network(a layer 2 protocol) into its DEX from the ground up. This will facilitate the functionalities of a DEX without any of the drawbacks of the CEX's and the DEX's we have today. Heres someone much more qualified than me, Andreas Antonopoulos, to explain this https://streamable.com/kzpimj 'Once we have efficient, well designed DEX's on layer 2, there wont even be any DEX's on layer 1' Progress The Stakenet team were the first to envision this grand solution and have been working on it since its conception in June 2019. They have been making steady progress ever since and right now, the DEX is in an open beta stage where rigorous testing is constant by themselves and the public. For a project of this scale, stress testing is paramount. If the product were to launch with any bugs/errors that would result in the loss of a users funds, this would obviously be very damaging to Stakenet's reputation. So I believe that the developers conservative approach is wise. As of now the only pairs tradeable on the DEX are XSN/BTC and LTC/BTC. The DEX has only just launched as a public beta and is not in its full public release stage yet. As development moves forward more lightning network and atomic swap compatible coins will be added to the DEX, and of course, the team are hard at work on Raiden Integration - this will allow ETH and tokens on the Ethereum blockchain to be traded on the DEX between separate blockchains(instantly, cheaply, privately) This is where Stakenet enters top 50 territory on CMC if successful and is the true value here. Raiden Integration is well underway is being tested in a closed public group on Linux. The full public DEX with Raiden Integration is expected to release by the end of the year. Given the state of development so far and the rate of progress, this seems realistic. Tokenomics 2.6 Metrics overview (from whitepaper)
Ticker: XSN. Currency type: Coin.
Consensus: Minting Proof of Stake, Trustless Proof of Stake.
XSN is slightly inflationary, much like ETH as this is necessary for the economy to be adopted and work in the long term. There is however a deflationary mechanism in place - all trading fees on the DEX get converted to XSN and 10% of these fees are burned. This puts constant buying pressure on XSN and acts as a deflationary mechanism. XSN has inherent value because it makes up the infrastructure that the DEX will run off and as such Masternode operators and Stakers will see the fee's from the DEX. Conclusion We can clearly see that a layer 2 DEX is the future of crypto currency trading. It will facilitate secure, cheap, instant and private trading across all coins with lightning capabilities, thus solving the scaling and transaction issues that are holding back crypto today. I dont need to tell you the implications of this, and what it means for crypto as a whole. If Stakenet can launch a layer 2 DEX with Raiden Integration, It will become the primary DEX in terms of volume. Stakenet DEX will most likely be the first layer 2 DEX(first mover advantage) and its blockchain is the infrastructure that will host this DEX and subsequently receive it's trading fee's. It is not difficult to envision a time in the next year when Stakenet DEX is functional and hosting hundreds of millions of dollars worth of trading every single day. At $30 million market cap, I cant see any other potential investment right now with this much potential upside. This post has merely served as in introduction and a heads up for this project, there is MUCH more to cover like vortex liquidity, masternodes, TOR integration... for now, here is some additional reading.

Meter.ioaims to create a low volatile currency following 10 kwh electricity price. Meter uses a hybrid PoW/PoS solution; PoW mining for stable coin creation and PoS for txn ordering
MTR is stablecoin soft pegged around the global competitive price of 10 kwh electricity
MTRG is the finite supply governance token, which is used by PoS validators to validate transactions.
Pow mining in Meter is as open and decentralized as in Bitcoin but differs from that in Bitcoin in two fundamental ways
Block rewards are dynamic. It’s determined as a function of pow difficulty. The wining Meter miner will earn more MTR if hash rate is high and less MTR if hash rate is low, ensuring a stable cost of production for each MTR at 10 kWh electricity price using mainstream mining equipment
Miner’s don’t validate transactions. They simply compete to solve PoW. Txn ordering is done by PoS validators who secure the network and in return earn txn fees.
All stablecoins must essentialy have stability mechanisms to account for cases where demand is high and where demand is low. MTR has 2 stability mechanisms set to solve this mission. Supply side stability mechanism (long term) First and foremost MTR can’t be produced out of thin air. It’s issuance follows a disciplined monetary policy that solely depends on profit seeking behavior of miners. The only way to issue MTR is via PoW mining. When miners notice that price of MTR is getting higher than the cost to produce them (remember cost of production is always fixed at 10 kwh elec. price = around 0.9-1.2 usd) they will turn on their equipment and start creating new supply. If demand keeps increasing more miners will join, and more MTR will be printed to keep up with demand. Eventually supply will outperfrom the demand and price will get back to equilibrium. When demand is low and MTR price is dropping below 10 kwh elec. price miners will not risk their profit margin to shrink and switch to mine other coins instead of MTR. In return MTR production will stop and no additional MTR will enter circulation. Given that mining is a competitive, open enviroment, price of MTR will eventually equal to the cost to produce it. (Marginal Revenue = Marginal Cost). The long term stability is achieved through this unique and simple mechanism at layer 1 which doesn’t require use of capital inefficient collateral, complicated oracles, seignorage shares or algorithmic rebasing mechanisms. Relative to nation based fiat currencies, switching cost between crytocurrencies is significantly lower. Sudden demand changes in crypto is therefore very common and must be addressed. Huge drop in demand may temporarly cause MTR to get traded below it’s cost of production making pow mining a losing game. How can the system recover from that and restart production? On the contrary, a sudden increase in demand may cause MTR to get traded at a premium making mining temporarly very profitable. Meter has a second layer stability mechanism in order to absorb sudden demand changes. Demand side stability mechanism (short term) An on chain auction (will become live in October 2020) resets every 24 hours offering newly minted fixed number of MTRGs in exchange for bids in MTR. Participants bid at no specific price and at the end of auction recieve MTRG proportional to their percentage of total bid. The main purpose of this auction is to consume MTR. A portion of MTR (initally %60) that is bidded in the auction ends up going to a reserve that is collectively owned by MTRG holders, essentially getting out of circulation. Future use of MTR in Reserve can be decided by governance. The remaining %40 gets gradually distributed to PoS validators as block rewards. This reserve allocation ratio can be adjusted via governance depending on the amount of MTR needed to be removed out of circulation at any point in time. Meter team working to make Meter compatible with other blockchain. In fact both MTR and MTRG can currently be 1:1 bridged to their Ethereum versions as eMTR and eMTRG respectively. In near term, stablecoin MTR is set out on a mission to serve as collateral and a crypto native unit of account for DeFi.
A criticism of the article "Six monetarist errors: why emission won't feed inflation"
(be gentle, it's my first RI attempt, :P; I hope I can make justice to the subject, this is my layman understanding of many macro subjects which may be flawed...I hope you can illuminate me if I have fallen short of a good RI) Introduction So, today a heterodox leaning Argentinian newspaper, Ambito Financiero, published an article criticizing monetarism called "Six monetarist errors: why emission won't feed inflation". I find it doesn't properly address monetarism, confuses it with other "economic schools" for whatever the term is worth today and it may be misleading, so I was inspired to write a refutation and share it with all of you. In some ways criticizing monetarism is more of a historical discussion given the mainstream has changed since then. Stuff like New Keynesian models are the bleeding edge, not Milton Friedman style monetarism. It's more of a symptom that Argentinian political culture is kind of stuck in the 70s on economics that this things keep being discussed. Before getting to the meat of the argument, it's good to have in mind some common definitions about money supply measures (specifically, MB, M1 and M2). These definitions apply to US but one can find analogous stuff for other countries. Argentina, for the lack of access to credit given its economic mismanagement and a government income decrease because of the recession, is monetizing deficits way more than before (like half of the budget, apparently, it's money financed) yet we have seen some disinflation (worth mentioning there are widespread price freezes since a few months ago). The author reasons that monetary phenomena cannot explain inflation properly and that other explanations are needed and condemns monetarism. Here are the six points he makes: 1.Is it a mechanical rule?
This way, we can ask by symmetry: if a certainty exists that when emission increases, inflation increases, the reverse should happen when emission becomes negative, obtaining negative inflation. Nonetheless, we know this happens: prices have an easier time increasing and a lot of rigidity decreasing. So the identity between emission and inflation is not like that, deflation almost never exists and the price movement rhythm cannot be controlled remotely only with money quantity. There is no mechanical relationship between one thing and the other.
First, the low hanging fruit: deflation is not that uncommon, for those of you that live in US and Europe it should be obvious given the difficulties central banks had to achieve their targets, but even Argentina has seen deflation during its depression 20 years ago. Second, we have to be careful with what we mean by emission. A statement of quantity theory of money (extracted from "Money Growth and Inflation: How Long is the Long-Run?") would say:
Inflation occurs when the average level of prices increases. Individual price increases in and of themselves do not equal inflation, but an overall pattern of price increases does. The price level observed in the economy is that which leads the quantity of money supplied to equal the quantity of money demanded. The quantity of money supplied is largely controlled by the [central bank]. When the supply of money increases or decreases, the price level must adjust to equate the quantity of money demanded throughout the economy with the quantity of money supplied. The quantity of money demanded depends not only on the price level but also on the level of real income, as measured by real gross domestic product (GDP), and a variety of other factors including the level of interest rates and technological advances such as the invention of automated teller machines. Money demand is widely thought to increase roughly proportionally with the price level and with real income. That is, if prices go up by 10 percent, or if real income increases by 10 percent, empirical evidence suggests people want to hold 10 percent more money. When the money supply grows faster than the money demand associated with rising real incomes and other factors, the price level must rise to equate supply and demand. That is, inflation occurs. This situation is often referred to as too many dollars chasing too few goods. Note that this theory does not predict that any money-supply growth will lead to inflation—only that part of money supply growth that exceeds the increase in money demand associated with rising real GDP (holding the other factors constant).
So it's not mere emission, but money supply growing faster than money demand which we should consider. So negative emission is not necessary condition for deflation in this theory. It's worth mentioning that the relationship with prices is observed for a broad measure of money (M2) and after a lag. From the same source of this excerpt one can observe in Fig. 3a the correlation between inflation and money growth for US becomes stronger the longer data is averaged. Price rigidities don't have to change this long term relationship per se. But what about causality and Argentina? This neat paper shows regressions in two historical periods: 1976-1989 and 1991-2001. The same relationship between M2 and inflation is observed, stronger in the first, highly inflationary period and weaker in the second, more stable, period. The regressions a 1-1 relationship in the high inflation period but deviates a bit in the low inflation period (yet the relationship is still there). Granger causality, as interpreted in the paper, shows prices caused money growth in the high inflation period (arguably because spending was monetized) while the reverse was true for the more stable period. So one can argue that there is a mechanical relationship, albeit one that is more complicated than simple QTOM theory. The relationship is complicated too for low inflation economies, it gets more relevant the higher inflation is. Another point the author makes is that liquidity trap is often ignored. I'll ignore the fact that you need specific conditions for the liquidity trap to be relevant to Argentina and address the point. Worth noting that while market monetarists (not exactly old fashioned monetarists) prefer alternative explanations for monetary policy with very low interest rates, this phenomena has a good monetary basis, as explained by Krugman in his famous japanese liquidity trap paper and his NYT blog (See this and this for some relevant articles). The simplified version is that while inflation may follow M2 growth with all the qualifiers needed, central banks may find difficulties targeting inflation when interest rates are low and agents are used to credible inflation targets. Central banks can change MB, not M2 and in normal times is good enough, but at those times M2 is out of control and "credibly irresponsible" policies are needed to return to normal (a more detailed explanation can be found in that paper I just linked, go for it if you are still curious). It's not like monetary policy is not good, it's that central banks have to do very unconventional stuff to achieve in a low interest rate environment. It's still an open problem but given symmetric inflation targeting policies are becoming more popular I'm optimistic. 2 - Has inflation one or many causes?
In Argentina we know that the main determinant of inflation is dollar price increases. On that, economic concentration of key markets, utility price adjustments, fuel prices, distributive struggles, external commodity values, expectatives, productive disequilibrium, world interest rates, the economic cycle, stationality and external sector restrictions act on it too. Let's see a simple example: during Macri's government since mid 2017 to 2019 emission was practically null, but when in 2018 the dollar value doubled, inflation doubled too (it went from 24% to 48% in 2018) and it went up again a year later. We see here that the empirical validity of monetarist theory was absent.
For the first paragraph, one could try to run econometric tests for all those variables, at least from my layman perspective. But given that it doesn't pass the smell test (has any country used that in its favor ignoring monetary policy? Also, I have shown there is at least some evidence for the money-price relationship before), I'll try to address what happened in Macri's government and if monetarism (or at least some reasonable extension of it) cannot account for it. For a complete description of macroeconomic policy on that period, Sturzenegger account is a good one (even if a bit unreliable given he was the central banker for that government and he is considered to have been a failure). The short version is that central banks uses bonds to manage monetary policy and absorb money; given the history of defaults for the country, the Argentinian Central Bank (BCRA) uses its own peso denominated bonds instead of using treasury bonds. At that time period, the BCRA still financed the treasury but the amount got reduced. Also, it emitted pesos to buy dollar reserves, then sterilized them, maybe risking credibility further. Near the end of 2017 it was evident the government had limited appetite for budget cuts, it had kind of abandoned its inflation target regime and the classic problem of fiscal dominance emerged, as it's shown in the classic "Unpleasant monetarist arithmetic" paper by Wallace and Sargent. Monetary policy gets less effective when the real value of bonds falls, and raising interest rates may be counterproductive in that environment. Rational expectations are needed to complement QTOM. So, given that Argentina promised to go nowhere with reform, it was expected that money financing would increase at some point in the future and BCRA bonds were dumped in 2018 and 2019 as their value was perceived to have decreased, and so peso demand decreased. It's not that the dollar value increased and inflation followed, but instead that peso demand fell suddenly! The IMF deal asked for MB growth to be null or almost null but that doesn't say a lot about M2 (which it's the relevant variable here). Without credible policies, the peso demand keeps falling because bonds are dumped even more (see 2019 for a hilariously brutal example of that). It's not emission per se, but rather that it doesn't adjust properly to peso demand (which is falling). That doesn't mean increasing interest rates is enough to achieve it, following Wallace and Sargent model. This is less a strict proof that a monetary phenomenon is involved and more stating that the author hasn't shown any problem with that, there are reasonable models for this situation. It doesn't look like an clear empirical failure to me yet. 3 - Of what we are talking about when we talk about emission? The author mentions many money measures (M0, M1, M2) but it doesn't address it meaningfully as I tried to do above. It feels more like a rhetorical device because there is no point here except "this stuff exists". Also, it's worth pointing that there are actual criticisms to make to Friedman on those grounds. He failed to forecast US inflation at some points when he switched to M1 instead of using M2, although he later reverted that. Monetarism kind of "failed" there (it also "failed" in the sense that modern central banks don't use money, but instead interest rates as their main tool; "failed" because despite being outdated, it was influential to modern central banking). This is often brought to this kind of discussions like if economics hasn't moved beyond that. For an account of Friedman thoughts on monetary policies and his failures, see this. 4 - Why do many countries print and inflation doesn't increase there? There is a mention about the japanese situation in the 90s (the liquidity trap) which I have addressed. The author mentions that many countries "printed" like crazy during the pandemic, and he says:
Monetarism apologists answer, when confronted with those grave empirical problems that happen in "serious countries", that the population "trusts" their monetary authorities, even increasing the money demand in those place despite the emission. Curious, though, it's an appeal to "trust" implying that the relationship between emission and inflation is not objective, but subjective and cultural: an appreciation that abandons mechanicism and the basic certainty of monetarism, because evaluations and diagnostics, many times ideologic, contextual or historical intervene..
That's just a restatement of applying rational expectations to central bank operations. I don't see a problem with that. Rational expectations is not magic, it's an assessment of future earnings by economic actors. Humans may not 100% rational but central banking somehow works on many countries. You cannot just say that people are ideologues and let it at that. What's your model? Worth noting the author shills for bitcoin a bit in this section, for more cringe. 5 - Are we talking of a physical science or a social science? Again, a vague mention of rational expectations ("populists and pro market politicians could do the same policies with different results because of how agents respond ideologically and expectatives") without handling the subject meaningfully. It criticizes universal macroeconomic rules that apply everywhere (this is often used to dismiss evidence from other countries uncritically more than as a meaningful point). 6 - How limits work?
The last question to monetarism allows to recognize it something: effectively we can think on a type of vinculation between emission and inflation in extreme conditions. That means, with no monetary rule, no government has the need of taxes but instead can emit and spend all it needs without consequence. We know it's not like that: no government can print infinitely without undesirable effects.
Ok, good disclaimer, but given what he wrote before, what's the mechanism which causes money printing to be inflationary at some point? It was rejected before but now it seems that it exists. What was even the point of the article?
Now, the problem is thinking monetarism on its extremes: without emission we have inflation sometimes, on others we have no inflation with emission, we know that if we have negative emission that doesn't guarantees us negative inflation, but that if emission is radically uncontrolled there will economic effects.
As I wrote above, that's not what monetarism (even on it's simpler form) says, nor a consequence of it. You can see some deviations in low inflation environment but it's not really Argentina's current situation.
Let's add other problems: the elastic question between money and prices is not evident. Neither is time lags in which can work or be neutral. So the question is the limit cases for monetarism which has some reason but some difficulty in explaining them: by which and it what moments rules work and in which it doesn't.
I find the time lag thing to be a red herring. You can observe empirically and not having a proper short/middle run model doesn't invalidate QTOM in the long run. While it may be that increasing interest rates or freezing MB is not effective, that's less a problem of the theory and more a problem of policy implementation. Conclusion: I find that the article doesn't truly get monetarism to begin with (see the points it makes about emission and money demand), neither how it's implemented in practice, nor seems to be aware of more modern theories that, while put money on the background, don't necessarily invalidate it (rational expectation ideas, and eventually New Keynesian stuff which addresses stuff like liquidity traps properly). There are proper criticisms to be made to Friedman old ideas but he still was a relevant man in his time and the economic community has moved on to new, better theories that have some debt to it. I feel most economic discussion about monetarism in Argentina is a strawman of mainstream economics or an attack on Austrians more than genuine points ("monetarism" is used as a shorthand for those who think inflation is a monetary phenomenon more than referring to Friedman and his disciples per se).
Hey all, I've been researching coins since 2017 and have gone through 100s of them in the last 3 years. I got introduced to blockchain via Bitcoin of course, analyzed Ethereum thereafter and from that moment I have a keen interest in smart contact platforms. I’m passionate about Ethereum but I find Zilliqa to have a better risk-reward ratio. Especially because Zilliqa has found an elegant balance between being secure, decentralized and scalable in my opinion.
Below I post my analysis of why from all the coins I went through I’m most bullish on Zilliqa (yes I went through Tezos, EOS, NEO, VeChain, Harmony, Algorand, Cardano etc.). Note that this is not investment advice and although it's a thorough analysis there is obviously some bias involved. Looking forward to what you all think!
Fun fact: the name Zilliqa is a play on ‘silica’ silicon dioxide which means “Silicon for the high-throughput consensus computer.”
This post is divided into (i) Technology, (ii) Business & Partnerships, and (iii) Marketing & Community. I’ve tried to make the technology part readable for a broad audience. If you’ve ever tried understanding the inner workings of Bitcoin and Ethereum you should be able to grasp most parts. Otherwise, just skim through and once you are zoning out head to the next part.
Technology and some more:
The technology is one of the main reasons why I’m so bullish on Zilliqa. First thing you see on their website is: “Zilliqa is a high-performance, high-security blockchain platform for enterprises and next-generation applications.” These are some bold statements.
Before we deep dive into the technology let’s take a step back in time first as they have quite the history. The initial research paper from which Zilliqa originated dates back to August 2016: Elastico: A Secure Sharding Protocol For Open Blockchains where Loi Luu (Kyber Network) is one of the co-authors. Other ideas that led to the development of what Zilliqa has become today are: Bitcoin-NG, collective signing CoSi, ByzCoin and Omniledger.
The technical white paper was made public in August 2017 and since then they have achieved everything stated in the white paper and also created their own open source intermediate level smart contract language called Scilla (functional programming language similar to OCaml) too.
Mainnet is live since the end of January 2019 with daily transaction rates growing continuously. About a week ago mainnet reached 5 million transactions, 500.000+ addresses in total along with 2400 nodes keeping the network decentralized and secure. Circulating supply is nearing 11 billion and currently only mining rewards are left. The maximum supply is 21 billion with annual inflation being 7.13% currently and will only decrease with time.
Zilliqa realized early on that the usage of public cryptocurrencies and smart contracts were increasing but decentralized, secure, and scalable alternatives were lacking in the crypto space. They proposed to apply sharding onto a public smart contract blockchain where the transaction rate increases almost linear with the increase in the amount of nodes. More nodes = higher transaction throughput and increased decentralization. Sharding comes in many forms and Zilliqa uses network-, transaction- and computational sharding. Network sharding opens up the possibility of using transaction- and computational sharding on top. Zilliqa does not use state sharding for now. We’ll come back to this later.
Before we continue dissecting how Zilliqa achieves such from a technological standpoint it’s good to keep in mind that a blockchain being decentralised and secure and scalable is still one of the main hurdles in allowing widespread usage of decentralised networks. In my opinion this needs to be solved first before blockchains can get to the point where they can create and add large scale value. So I invite you to read the next section to grasp the underlying fundamentals. Because after all these premises need to be true otherwise there isn’t a fundamental case to be bullish on Zilliqa, right?
Down the rabbit hole
How have they achieved this? Let’s define the basics first: key players on Zilliqa are the users and the miners. A user is anybody who uses the blockchain to transfer funds or run smart contracts. Miners are the (shard) nodes in the network who run the consensus protocol and get rewarded for their service in Zillings (ZIL). The mining network is divided into several smaller networks called shards, which is also referred to as ‘network sharding’. Miners subsequently are randomly assigned to a shard by another set of miners called DS (Directory Service) nodes. The regular shards process transactions and the outputs of these shards are eventually combined by the DS shard as they reach consensus on the final state. More on how these DS shards reach consensus (via pBFT) will be explained later on.
The Zilliqa network produces two types of blocks: DS blocks and Tx blocks. One DS Block consists of 100 Tx Blocks. And as previously mentioned there are two types of nodes concerned with reaching consensus: shard nodes and DS nodes. Becoming a shard node or DS node is being defined by the result of a PoW cycle (Ethash) at the beginning of the DS Block. All candidate mining nodes compete with each other and run the PoW (Proof-of-Work) cycle for 60 seconds and the submissions achieving the highest difficulty will be allowed on the network. And to put it in perspective: the average difficulty for one DS node is ~ 2 Th/s equaling 2.000.000 Mh/s or 55 thousand+ GeForce GTX 1070 / 8 GB GPUs at 35.4 Mh/s. Each DS Block 10 new DS nodes are allowed. And a shard node needs to provide around 8.53 GH/s currently (around 240 GTX 1070s). Dual mining ETH/ETC and ZIL is possible and can be done via mining software such as Phoenix and Claymore. There are pools and if you have large amounts of hashing power (Ethash) available you could mine solo.
The PoW cycle of 60 seconds is a peak performance and acts as an entry ticket to the network. The entry ticket is called a sybil resistance mechanism and makes it incredibly hard for adversaries to spawn lots of identities and manipulate the network with these identities. And after every 100 Tx Blocks which corresponds to roughly 1,5 hour this PoW process repeats. In between these 1,5 hour, no PoW needs to be done meaning Zilliqa’s energy consumption to keep the network secure is low. For more detailed information on how mining works click here. Okay, hats off to you. You have made it this far. Before we go any deeper down the rabbit hole we first must understand why Zilliqa goes through all of the above technicalities and understand a bit more what a blockchain on a more fundamental level is. Because the core of Zilliqa’s consensus protocol relies on the usage of pBFT (practical Byzantine Fault Tolerance) we need to know more about state machines and their function. Navigate to Viewblock, a Zilliqa block explorer, and just come back to this article. We will use this site to navigate through a few concepts.
We have established that Zilliqa is a public and distributed blockchain. Meaning that everyone with an internet connection can send ZILs, trigger smart contracts, etc. and there is no central authority who fully controls the network. Zilliqa and other public and distributed blockchains (like Bitcoin and Ethereum) can also be defined as state machines.
Taking the liberty of paraphrasing examples and definitions given by Samuel Brooks’ medium article, he describes the definition of a blockchain (like Zilliqa) as: “A peer-to-peer, append-only datastore that uses consensus to synchronize cryptographically-secure data”.
Next, he states that: "blockchains are fundamentally systems for managing valid state transitions”. For some more context, I recommend reading the whole medium article to get a better grasp of the definitions and understanding of state machines. Nevertheless, let’s try to simplify and compile it into a single paragraph. Take traffic lights as an example: all its states (red, amber, and green) are predefined, all possible outcomes are known and it doesn’t matter if you encounter the traffic light today or tomorrow. It will still behave the same. Managing the states of a traffic light can be done by triggering a sensor on the road or pushing a button resulting in one traffic lights’ state going from green to red (via amber) and another light from red to green.
With public blockchains like Zilliqa, this isn’t so straightforward and simple. It started with block #1 almost 1,5 years ago and every 45 seconds or so a new block linked to the previous block is being added. Resulting in a chain of blocks with transactions in it that everyone can verify from block #1 to the current #647.000+ block. The state is ever changing and the states it can find itself in are infinite. And while the traffic light might work together in tandem with various other traffic lights, it’s rather insignificant comparing it to a public blockchain. Because Zilliqa consists of 2400 nodes who need to work together to achieve consensus on what the latest valid state is while some of these nodes may have latency or broadcast issues, drop offline or are deliberately trying to attack the network, etc.
Now go back to the Viewblock page take a look at the amount of transaction, addresses, block and DS height and then hit refresh. Obviously as expected you see new incremented values on one or all parameters. And how did the Zilliqa blockchain manage to transition from a previous valid state to the latest valid state? By using pBFT to reach consensus on the latest valid state.
After having obtained the entry ticket, miners execute pBFT to reach consensus on the ever-changing state of the blockchain. pBFT requires a series of network communication between nodes, and as such there is no GPU involved (but CPU). Resulting in the total energy consumed to keep the blockchain secure, decentralized and scalable being low.
pBFT stands for practical Byzantine Fault Tolerance and is an optimization on the Byzantine Fault Tolerant algorithm. To quote Blockonomi: “In the context of distributed systems, Byzantine Fault Tolerance is the ability of a distributed computer network to function as desired and correctly reach a sufficient consensus despite malicious components (nodes) of the system failing or propagating incorrect information to other peers.” Zilliqa is such a distributed computer network and depends on the honesty of the nodes (shard and DS) to reach consensus and to continuously update the state with the latest block. If pBFT is a new term for you I can highly recommend the Blockonomi article.
The idea of pBFT was introduced in 1999 - one of the authors even won a Turing award for it - and it is well researched and applied in various blockchains and distributed systems nowadays. If you want more advanced information than the Blockonomi link provides click here. And if you’re in between Blockonomi and the University of Singapore read the Zilliqa Design Story Part 2 dating from October 2017. Quoting from the Zilliqa tech whitepaper: “pBFT relies upon a correct leader (which is randomly selected) to begin each phase and proceed when the sufficient majority exists. In case the leader is byzantine it can stall the entire consensus protocol. To address this challenge, pBFT offers a view change protocol to replace the byzantine leader with another one.”
pBFT can tolerate ⅓ of the nodes being dishonest (offline counts as Byzantine = dishonest) and the consensus protocol will function without stalling or hiccups. Once there are more than ⅓ of dishonest nodes but no more than ⅔ the network will be stalled and a view change will be triggered to elect a new DS leader. Only when more than ⅔ of the nodes are dishonest (66%) double-spend attacks become possible.
If the network stalls no transactions can be processed and one has to wait until a new honest leader has been elected. When the mainnet was just launched and in its early phases, view changes happened regularly. As of today the last stalling of the network - and view change being triggered - was at the end of October 2019.
Another benefit of using pBFT for consensus besides low energy is the immediate finality it provides. Once your transaction is included in a block and the block is added to the chain it’s done. Lastly, take a look at this article where three types of finality are being defined: probabilistic, absolute and economic finality. Zilliqa falls under the absolute finality (just like Tendermint for example). Although lengthy already we skipped through some of the inner workings from Zilliqa’s consensus: read the Zilliqa Design Story Part 3 and you will be close to having a complete picture on it. Enough about PoW, sybil resistance mechanism, pBFT, etc. Another thing we haven’t looked at yet is the amount of decentralization.
Currently, there are four shards, each one of them consisting of 600 nodes. 1 shard with 600 so-called DS nodes (Directory Service - they need to achieve a higher difficulty than shard nodes) and 1800 shard nodes of which 250 are shard guards (centralized nodes controlled by the team). The amount of shard guards has been steadily declining from 1200 in January 2019 to 250 as of May 2020. On the Viewblock statistics, you can see that many of the nodes are being located in the US but those are only the (CPU parts of the) shard nodes who perform pBFT. There is no data from where the PoW sources are coming. And when the Zilliqa blockchain starts reaching its transaction capacity limit, a network upgrade needs to be executed to lift the current cap of maximum 2400 nodes to allow more nodes and formation of more shards which will allow to network to keep on scaling according to demand. Besides shard nodes there are also seed nodes. The main role of seed nodes is to serve as direct access points (for end-users and clients) to the core Zilliqa network that validates transactions. Seed nodes consolidate transaction requests and forward these to the lookup nodes (another type of nodes) for distribution to the shards in the network. Seed nodes also maintain the entire transaction history and the global state of the blockchain which is needed to provide services such as block explorers. Seed nodes in the Zilliqa network are comparable to Infura on Ethereum.
The seed nodes were first only operated by Zilliqa themselves, exchanges and Viewblock. Operators of seed nodes like exchanges had no incentive to open them for the greater public. They were centralised at first. Decentralisation at the seed nodes level has been steadily rolled out since March 2020 ( Zilliqa Improvement Proposal 3 ). Currently the amount of seed nodes is being increased, they are public-facing and at the same time PoS is applied to incentivize seed node operators and make it possible for ZIL holders to stake and earn passive yields. Important distinction: seed nodes are not involved with consensus! That is still PoW as entry ticket and pBFT for the actual consensus.
5% of the block rewards are being assigned to seed nodes (from the beginning in 2019) and those are being used to pay out ZIL stakers. The 5% block rewards with an annual yield of 10.03% translate to roughly 610 MM ZILs in total that can be staked. Exchanges use the custodial variant of staking and wallets like Moonlet will use the non-custodial version (starting in Q3 2020). Staking is being done by sending ZILs to a smart contract created by Zilliqa and audited by Quantstamp.
With a high amount of DS; shard nodes and seed nodes becoming more decentralized too, Zilliqa qualifies for the label of decentralized in my opinion.
Generalized: programming languages can be divided into being ‘object-oriented’ or ‘functional’. Here is an ELI5 given by software development academy: * “all programs have two basic components, data – what the program knows – and behavior – what the program can do with that data. So object-oriented programming states that combining data and related behaviors in one place, is called “object”, which makes it easier to understand how a particular program works. On the other hand, functional programming argues that data and behavior are different things and should be separated to ensure their clarity.” *
Scilla is on the functional side and shares similarities with OCaml: OCaml is a general-purpose programming language with an emphasis on expressiveness and safety. It has an advanced type system that helps catch your mistakes without getting in your way. It's used in environments where a single mistake can cost millions and speed matters, is supported by an active community, and has a rich set of libraries and development tools. For all its power, OCaml is also pretty simple, which is one reason it's often used as a teaching language.
Scilla is blockchain agnostic, can be implemented onto other blockchains as well, is recognized by academics and won a so-called Distinguished Artifact Award award at the end of last year.
One of the reasons why the Zilliqa team decided to create their own programming language focused on preventing smart contract vulnerabilities is that adding logic on a blockchain, programming, means that you cannot afford to make mistakes. Otherwise, it could cost you. It’s all great and fun blockchains being immutable but updating your code because you found a bug isn’t the same as with a regular web application for example. And with smart contracts, it inherently involves cryptocurrencies in some form thus value.
Another difference with programming languages on a blockchain is gas. Every transaction you do on a smart contract platform like Zilliqa or Ethereum costs gas. With gas you basically pay for computational costs. Sending a ZIL from address A to address B costs 0.001 ZIL currently. Smart contracts are more complex, often involve various functions and require more gas (if gas is a new concept click here ).
So with Scilla, similar to Solidity, you need to make sure that “every function in your smart contract will run as expected without hitting gas limits. An improper resource analysis may lead to situations where funds may get stuck simply because a part of the smart contract code cannot be executed due to gas limits. Such constraints are not present in traditional software systems”.Scilla design story part 1
Some examples of smart contract issues you’d want to avoid are: leaking funds, ‘unexpected changes to critical state variables’ (example: someone other than you setting his or her address as the owner of the smart contract after creation) or simply killing a contract.
Scilla also allows for formal verification. Wikipedia to the rescue: In the context of hardware and software systems, formal verification is the act of proving or disproving the correctness of intended algorithms underlying a system with respect to a certain formal specification or property, using formal methods of mathematics.
Formal verification can be helpful in proving the correctness of systems such as: cryptographic protocols, combinational circuits, digital circuits with internal memory, and software expressed as source code.
“Scilla is being developed hand-in-hand with formalization of its semantics and its embedding into the Coq proof assistant — a state-of-the art tool for mechanized proofs about properties of programs.”
Simply put, with Scilla and accompanying tooling developers can be mathematically sure and proof that the smart contract they’ve written does what he or she intends it to do.
Smart contract on a sharded environment and state sharding
There is one more topic I’d like to touch on: smart contract execution in a sharded environment (and what is the effect of state sharding). This is a complex topic. I’m not able to explain it any easier than what is posted here. But I will try to compress the post into something easy to digest.
Earlier on we have established that Zilliqa can process transactions in parallel due to network sharding. This is where the linear scalability comes from. We can define simple transactions: a transaction from address A to B (Category 1), a transaction where a user interacts with one smart contract (Category 2) and the most complex ones where triggering a transaction results in multiple smart contracts being involved (Category 3). The shards are able to process transactions on their own without interference of the other shards. With Category 1 transactions that is doable, with Category 2 transactions sometimes if that address is in the same shard as the smart contract but with Category 3 you definitely need communication between the shards. Solving that requires to make a set of communication rules the protocol needs to follow in order to process all transactions in a generalised fashion.
There is no strict defined roadmap but here are topics being worked on. And via the Zilliqa website there is also more information on the projects they are working on.
Business & Partnerships
It’s not only technology in which Zilliqa seems to be excelling as their ecosystem has been expanding and starting to grow rapidly. The project is on a mission to provide OpenFinance (OpFi) to the world and Singapore is the right place to be due to its progressive regulations and futuristic thinking. Singapore has taken a proactive approach towards cryptocurrencies by introducing the Payment Services Act 2019 (PS Act). Among other things, the PS Act will regulate intermediaries dealing with certain cryptocurrencies, with a particular focus on consumer protection and anti-money laundering. It will also provide a stable regulatory licensing and operating framework for cryptocurrency entities, effectively covering all crypto businesses and exchanges based in Singapore. According to PWC 82% of the surveyed executives in Singapore reported blockchain initiatives underway and 13% of them have already brought the initiatives live to the market. There is also an increasing list of organizations that are starting to provide digital payment services. Moreover, Singaporean blockchain developers Building Cities Beyond has recently created an innovation $15 million grant to encourage development on its ecosystem. This all suggests that Singapore tries to position itself as (one of) the leading blockchain hubs in the world.
Zilliqa seems to already take advantage of this and recently helped launch Hg Exchange on their platform, together with financial institutions PhillipCapital, PrimePartners and Fundnel. Hg Exchange, which is now approved by the Monetary Authority of Singapore (MAS), uses smart contracts to represent digital assets. Through Hg Exchange financial institutions worldwide can use Zilliqa's safe-by-design smart contracts to enable the trading of private equities. For example, think of companies such as Grab, Airbnb, SpaceX that are not available for public trading right now. Hg Exchange will allow investors to buy shares of private companies & unicorns and capture their value before an IPO. Anquan, the main company behind Zilliqa, has also recently announced that they became a partner and shareholder in TEN31 Bank, which is a fully regulated bank allowing for tokenization of assets and is aiming to bridge the gap between conventional banking and the blockchain world. If STOs, the tokenization of assets, and equity trading will continue to increase, then Zilliqa’s public blockchain would be the ideal candidate due to its strategic positioning, partnerships, regulatory compliance and the technology that is being built on top of it.
What is also very encouraging is their focus on banking the un(der)banked. They are launching a stablecoin basket starting with XSGD. As many of you know, stablecoins are currently mostly used for trading. However, Zilliqa is actively trying to broaden the use case of stablecoins. I recommend everybody to read this text that Amrit Kumar wrote (one of the co-founders). These stablecoins will be integrated in the traditional markets and bridge the gap between the crypto world and the traditional world. This could potentially revolutionize and legitimise the crypto space if retailers and companies will for example start to use stablecoins for payments or remittances, instead of it solely being used for trading.
Zilliqa also released their DeFi strategic roadmap (dating November 2019) which seems to be aligning well with their OpFi strategy. A non-custodial DEX is coming to Zilliqa made by Switcheo which allows cross-chain trading (atomic swaps) between ETH, EOS and ZIL based tokens. They also signed a Memorandum of Understanding for a (soon to be announced) USD stablecoin. And as Zilliqa is all about regulations and being compliant, I’m speculating on it to be a regulated USD stablecoin. Furthermore, XSGD is already created and visible on block explorer and XIDR (Indonesian Stablecoin) is also coming soon via StraitsX. Here also an overview of the Tech Stack for Financial Applications from September 2019. Further quoting Amrit Kumar on this:
There are two basic building blocks in DeFi/OpFi though: 1) stablecoins as you need a non-volatile currency to get access to this market and 2) a dex to be able to trade all these financial assets. The rest are built on top of these blocks.
So far, together with our partners and community, we have worked on developing these building blocks with XSGD as a stablecoin. We are working on bringing a USD-backed stablecoin as well. We will soon have a decentralised exchange developed by Switcheo. And with HGX going live, we are also venturing into the tokenization space. More to come in the future.”
Additionally, they also have this ZILHive initiative that injects capital into projects. There have been already 6 waves of various teams working on infrastructure, innovation and research, and they are not from ASEAN or Singapore only but global: see Grantees breakdown by country. Over 60 project teams from over 20 countries have contributed to Zilliqa's ecosystem. This includes individuals and teams developing wallets, explorers, developer toolkits, smart contract testing frameworks, dapps, etc. As some of you may know, Unstoppable Domains (UD) blew up when they launched on Zilliqa. UD aims to replace cryptocurrency addresses with a human-readable name and allows for uncensorable websites. Zilliqa will probably be the only one able to handle all these transactions onchain due to ability to scale and its resulting low fees which is why the UD team launched this on Zilliqa in the first place. Furthermore, Zilliqa also has a strong emphasis on security, compliance, and privacy, which is why they partnered with companies like Elliptic, ChainSecurity (part of PwC Switzerland), and Incognito. Their sister company Aqilliz (Zilliqa spelled backwards) focuses on revolutionizing the digital advertising space and is doing interesting things like using Zilliqa to track outdoor digital ads with companies like Foodpanda.
Zilliqa is listed on nearly all major exchanges, having several different fiat-gateways and recently have been added to Binance’s margin trading and futures trading with really good volume. They also have a very impressive team with good credentials and experience. They don't just have “tech people”. They have a mix of tech people, business people, marketeers, scientists, and more. Naturally, it's good to have a mix of people with different skill sets if you work in the crypto space.
Marketing & Community
Zilliqa has a very strong community. If you just follow their Twitter their engagement is much higher for a coin that has approximately 80k followers. They also have been ‘coin of the day’ by LunarCrush many times. LunarCrush tracks real-time cryptocurrency value and social data. According to their data, it seems Zilliqa has a more fundamental and deeper understanding of marketing and community engagement than almost all other coins. While almost all coins have been a bit frozen in the last months, Zilliqa seems to be on its own bull run. It was somewhere in the 100s a few months ago and is currently ranked #46 on CoinGecko. Their official Telegram also has over 20k people and is very active, and their community channel which is over 7k now is more active and larger than many other official channels. Their local communities also seem to be growing.
Moreover, their community started ‘Zillacracy’ together with the Zilliqa core team ( see www.zillacracy.com ). It’s a community-run initiative where people from all over the world are now helping with marketing and development on Zilliqa. Since its launch in February 2020 they have been doing a lot and will also run their own non-custodial seed node for staking. This seed node will also allow them to start generating revenue for them to become a self sustaining entity that could potentially scale up to become a decentralized company working in parallel with the Zilliqa core team. Comparing it to all the other smart contract platforms (e.g. Cardano, EOS, Tezos etc.) they don't seem to have started a similar initiative (correct me if I’m wrong though). This suggests in my opinion that these other smart contract platforms do not fully understand how to utilize the ‘power of the community’. This is something you cannot ‘buy with money’ and gives many projects in the space a disadvantage.
Zilliqa also released two social products called SocialPay and Zeeves. SocialPay allows users to earn ZILs while tweeting with a specific hashtag. They have recently used it in partnership with the Singapore Red Cross for a marketing campaign after their initial pilot program. It seems like a very valuable social product with a good use case. I can see a lot of traditional companies entering the space through this product, which they seem to suggest will happen. Tokenizing hashtags with smart contracts to get network effect is a very smart and innovative idea.
Regarding Zeeves, this is a tipping bot for Telegram. They already have 1000s of signups and they plan to keep upgrading it for more and more people to use it (e.g. they recently have added a quiz features). They also use it during AMAs to reward people in real-time. It’s a very smart approach to grow their communities and get familiar with ZIL. I can see this becoming very big on Telegram. This tool suggests, again, that the Zilliqa team has a deeper understanding of what the crypto space and community needs and is good at finding the right innovative tools to grow and scale.
To be honest, I haven’t covered everything (i’m also reaching the character limited haha). So many updates happening lately that it's hard to keep up, such as the International Monetary Fund mentioning Zilliqa in their report, custodial and non-custodial Staking, Binance Margin, Futures, Widget, entering the Indian market, and more. The Head of Marketing Colin Miles has also released this as an overview of what is coming next. And last but not least, Vitalik Buterin has been mentioning Zilliqa lately acknowledging Zilliqa and mentioning that both projects have a lot of room to grow. There is much more info of course and a good part of it has been served to you on a silver platter. I invite you to continue researching by yourself :-) And if you have any comments or questions please post here!
So I had a few quick questions regarding the lightning network 1) what is your idea of a fully adopted lightning network look like? From my POV and understanding I’d imagine that it would still look like modern day banking systems. Where everyone forms a connection with big banks who have connections with everyone else and transactions flow through them. Solves problems of opening a node with a “coffee shop” or ecommerce store (as depicted in online examples). Opening and funding each individual connection seems tedious and complicated (I may be wrong in my thinking so please tell me if it works some other way) also solves the fear where you won’t be able to make a transaction if a node is down because basically all the banks would have to go down for that problem to occur 2) what would happen to the main blockchain if 90% of transactions were done on the lightning network? Considering that it’s faster and cheaper and you only need to use the blockchain to open and close the connections, everyone would only need to do 1 time payments to connect to major nodes. Reduced traffic on the blockchain and I assume less fees for miners, leading to miners shutting down, leading to less hash rate and risk for 51% attack. (I know difficulty would also decrease but just curious of the relevance of the main blockchain outside of opening/closing connections under complete adoption) Bonus question) how do you think super computers will affect Bitcoin? Difficulty will likely increase but do you think a few big miners getting their hands on super computers, pushing out smaller miners would make the chain more centralized? Love to hear your thoughts and I’d love to learn something new!
This week's BTC price rise has made me curious about BTC news, so I came across this piece of news on the internet https://www.trustnodes.com/2019/08/01/85-of-all-bitcoin-have-now-been-mined Quote: "Just circa half a million coins (about $ 5 billion) are now left to be mined until next year when the block rewards are halved to ₿6.25 from the current ₿12.5" the statement made me asking " My questions are: Is it still profitable to mine BTC? Will people leave mining or join in the next few years? What do you think about BTC price in general?
So I’ve seen a few estimates on the date, and I’m not sure how they are calculated other than standard block creation time. What could cause the date to come a few days earlier or later than the current estimates? Can anyone explain this to an idiot in layman’s terms? Thanks.
Solution Life is an open-source platform that enables to create peer-to-peer marketplace and ecommerce applications. https://preview.redd.it/ypmpkfwnb6s51.png?width=613&format=png&auto=webp&s=6936dbdd70f1626bb352a426f3b59383b8b8c9cc Solution Life aims at building a global sharing economy, allowing buyers and sellers to use segments of goods and services (car sharing, service missions, home sharing, etc.) to transact on the open, distributed source web. Using Ethereum blockchain and Interplanetary File System (IPFS), the platform and its participants can interact with the peer-to-peer model, allowing the creation and placement of services and goods without going through traditional middle parties. We plan to build a large-scale commercial network: • Exchange financial value directly (listing, transactions and service fees) from big corporations like Airbnb, Craigslist, Postmate, ... to individual buyers and retailers. • Exchange financial value and strategic value (internal aggregation of customer and transaction data) from similar corporations to entire ecosystems • Create new financial value for market participants who contribute to platform development (e.g. building new technology for the Solution Life platform, developing new vertical products and introducing new users and businesses) • Build the open, distributed, and shared data layer to promote transparency and collaboration • Allow the buyers and sellers in the world to transact without difficulty in converting currencies or tariffs • Promote personal freedom by not allowing a corporation or central government to impose arbitrary and overly conventional rules of business operation. To conduct these ambitious goals, we created the Solution Life Platform with programs that encourage technologists, businesses and consumers to build, contribute, and expand the ecosystem. We plan to build a broad collection of vertical industry applications (e.g. short vacation rental, free software engineering, tutoring) built on standards and data sharing Solution Life. When writing this article, the Solution Life platform is currently in Mainnet Beta. Platform Version 1.0 is expected to be activated in Quarter 3/2020. While the majority of engineering work is being done by the core engineering team, we expect future developments, after launching platform 1.0 from developer, will come to open source community members Together, we will create the Internet economy of the future. Details of Whitepaper: • Why is a new model of peer to peer trading necessary? • Benefits proposed on the Solution Life Platform • Product strategy, main features and technical overview • Overview of the Solution Life team and community https://preview.redd.it/tzepfegpb6s51.png?width=759&format=png&auto=webp&s=62c9933e84e9945b5417591e406390d127fa1070 BACKGROUND Since the appearance of the Internet, the digital marketplace has connected buyers and sellers of goods and services, allowing transactions that have never happened before. Craigslist launched in 1995 and dominated for many years in local and regional commerce. At the same time, eBay began to grow and create a whole new category of sales based on auction, creating a more efficient way of doing market business. Through 20 years of rapid change, many businesses on the Internet market in both B2C and B2B types have developed strongly. Currently, sharing economy markets such as Airbnb, Uber, Getaround, Fiverr and TaskRmus have been very successful in combining buyers and sellers of the sharing economy. Now, the use of distributed assets can be sold as easily as atomic items, and people around the world are exchanging their excess inventory, time, and skills for profit. New markets including the Gig economy, the service sector and the use of segment assets are particularly suitable to be basis for peer-to-peer systems built on blockchain. Most of the shared economic enterprises have some common points. Firstly, as a collection, these companies have made a big impact on the world. Consumers of the markets were able to improve their lives with access to products and services that they didn't have before. Vendors have been using these platforms to reach customers on a larger and easier scale than before. Each market creates a "private home" for consumers and suppliers to transact together, creating liquidity for that market. Secondly, most sharing economic enterprises follow the same growth cycle. Without a few exceptions, these famous markets are difficult to launch and grow. Enterprises in the market often have to start building with millions of dollars, and in terms of Uber and Airbnb, these two businesses spend billions of dollars to scale. That is also the reason why these businesses suffered serious losses in the early days. In fact, the corporation is subsidizing the use of marketplace for its users. However, due to the very positive cross-network effect, successful marketplace businesses can increase revenue exponentially over time, usually by charging a fee per transaction on the network. Network-effect enterprises, such as share economy market, are often enterprises occupying all directions and growing stage, gaining a disproportionate value from the network for corporation’s management and their shareholders. In many ways, they become the only dictator on the scale they achieve. Finally, although there are huge differences in user experience, business mechanics, and vertical specific features among companies on the Internet market, they all share many parts built and rebuild many times. Lyft, Postmate, and DoorDash themselves has designed their own solutions for user and supplier profiles, shopping experiences, matching algorithms, reviews, and ratings. This is proprietary technology that is valuable on one side. On the other hand, chasing useless things each time creates a new market vertically wasted time and effort. Consumers also create and manage dozens of accounts on these market enterprises themselves, each with their own personal data and transaction history. In the last few years, blockchain technology innovators and investors have called teams to build peer-topeer versions of businesses in the current sharing economy and to trade the Internet in a more efficient way. P2P lodging sites like Airbnb have already begun to transform the lodging industry by making a public market in private housing. However, adoption may be limited by concerns about safety and security (guests) and property damage (hosts). By enabling a secure, tamper-proof system for managing digital credentials and reputation, we believe blockchain could help accelerate the adoption of P2P lodging and generate.” - Goldman Sachs Research (Blockchain: Putting Theory into Practice) Don Tapscott, the author of the "Blockchain Revolution", said that Bitcoin-based technology could be used to promote the interest in Uber and Airbnb. - The Wall Street Journal "It is difficult for middle parties to achieve sustainable growth in business," [Fritz Joussen] said. "These platforms [tourism middle parties] build accessibility by spending billions of dollars on advertising, and then they generate exclusive profits based on what they have with sales and marketing. They provide great sales and marketing services. Booking.com is a big brand but they make outstanding profits because they own proprietary structures. Blockchain will destroy this. "- Skift However, most of the infrastructure and transmission systems for building distributed-market applications did not exist before Solution Life was born. We aim to address the shortcomings of current market companies and are happy that we have launched the Solution Life Platform, which opens up peer-to-peer commerce with corresponding scale. 📷 ACTIVATE THE OVER THE COUNTER MARKET Our vision is to build and develop a free service exchange on the new Internet. In order to do this, we have to build a simulation platform of most, if not all, of the functionality of a third-party intermediary on the blockchain and other distribution systems. This is an ambitious and technologically challenging goal, but we have already completed important milestones that demonstrate our technology and the realworld applications of the project. The Solution Life platform has 3 main elements, all of which are open sources: • Solution Life enabled end user applications • Solution Life platform for developers • Solution Life's application protocol Solution Life enables end user applications The Solution Life flagship marketplace app is our consumer marketplace product that allows buyers and sellers on the network to do business. It is available today on the web at shopSolution Life.com and on both iOS and Android mobile devices. 📷 Summary For the past two decades, Internet marketplaces and e-commerce stores have changed the way that buyers and sellers connect, creating new opportunities for the exchange of goods and services. However, these marketplaces have always been governed by centralized companies that maintain their individual monopolies on data, transaction and other service fees, and ultimately, user choice. With blockchain and other distributed technologies beginning to hit the mainstream, the world is poised for a new wave of decentralized commerce. SLC is bringing change and innovation to the global peer-to-peer economy. We're excited by the opportunity to lower fees, increase innovation, free customer and transaction data, and decrease censorship and unnecessary regulation. We are building a platform that invites other interested parties including developers and entrepreneurs to build this technology and community with us, altogether working to create the peer-to-peer economy of tomorrow. We hope you’ll join us on this exciting journey. TOKEN SOLUTION LIFE (SLC) The Solution Life Token (also known as SLC) is a utility token that serves multiple purposes in ensuring the health and growth of the network. The ERC20 contract is live on the Ethereum network today at: 0x4d44D6c288b7f32fF676a4b2DAfD625992f8Ffbd. At a high level, this token is intended to serve a number of key functions on the platform. First, the SLC is a multi-purpose incentive token that is intended to drive the behavior of end users, developers, market operators, and other ecosystem participants. Additionally, the SLC is an exchange intermediary that can be used for payments between buyers and sellers on the platform. Ultimately, it is intended that SLC will serve a vital part in future network governance. Since November 2020, the Solution Life token has been used to encourage various forms of participation from the platform's ecosystem participants. Token Solution Life is used to reward users, developers, marketplace operators and / or other participants for performing activities and services conducive to Platform development. Solution Life Rewards Solution Life is an incentive program targeted at end users on the Platform. Buyers and sellers on the platform have been able to earn SLC since our inaugural Solution Life Rewards campaign in Nov of 2020. Solution Life Rewards enables everyone to have a stake in the network. We’ve intentionally designed the program so that even novice, non-technical users can participate. With Solution Life Rewards, users can get SLC from account creation and identity verification. One of the best ways to network is through referrals. As such, end users can also earn tokens by inviting new users. This creates more confidence between the buyer and the seller. Users can also earn SLC by following Solution Life's social networking sites or promoting project news on public channels. To encourage trading volume on our Solution Life Platform, we also offer a refund mechanism for users who purchase from reputable sellers on our network. Solution Life Commissions Encouraging marketplace developers and managers to use the Solution Life platform is essential. Therefore, we launched an advertising and promotion program, creating an integrated business model for the decentralized marketplace running on Solution Life. Merchants on Solution Life apps can promote their listings using SLCs for greater visibility on search and browse results on our preferred and partner apps. The only way to join this program is to pay with SLC. When a merchant creates a listing, they can add a commission paid in SLC to their listing. This SLC is placed on escrow in the Marketplace Smart Contract.
Testing the Tide | Monthly FIRE Portfolio Update - June 2020
We would rather be ruined than changed. -W H Auden, The Age of Anxiety This is my forty-third portfolio update. I complete this update monthly to check my progress against my goal. Portfolio goal My objective is to reach a portfolio of $2 180 000 by 1 July 2021. This would produce a real annual income of about $87 000 (in 2020 dollars). This portfolio objective is based on an expected average real return of 3.99 per cent, or a nominal return of 6.49 per cent. Portfolio summary Vanguard Lifestrategy High Growth Fund – $726 306 Vanguard Lifestrategy Growth Fund – $42 118 Vanguard Lifestrategy Balanced Fund – $78 730 Vanguard Diversified Bonds Fund – $111 691 Vanguard Australian Shares ETF (VAS) – $201 745 Vanguard International Shares ETF (VGS) – $39 357 Betashares Australia 200 ETF (A200) – $231 269 Telstra shares (TLS) – $1 668 Insurance Australia Group shares (IAG) – $7 310 NIB Holdings shares (NHF) – $5 532 Gold ETF (GOLD.ASX) – $117 757 Secured physical gold – $18 913 Ratesetter (P2P lending) – $10 479 Bitcoin – $148 990 Raiz app (Aggressive portfolio) – $16 841 Spaceship Voyager app (Index portfolio) – $2 553 BrickX (P2P rental real estate) – $4 484 Total portfolio value: $1 765 743 (+$8 485 or 0.5%) Asset allocation Australian shares – 42.2% (2.8% under) Global shares – 22.0% Emerging markets shares – 2.3% International small companies – 3.0% Total international shares – 27.3% (2.7% under) Total shares – 69.5% (5.5% under) Total property securities – 0.3% (0.3% over) Australian bonds – 4.7% International bonds – 9.4% Total bonds – 14.0% (1.0% under) Gold – 7.7% Bitcoin – 8.4% Gold and alternatives – 16.2% (6.2% over) Presented visually, below is a high-level view of the current asset allocation of the portfolio. [Chart] Comments The overall portfolio increased slightly over the month. This has continued to move the portfolio beyond the lows seen in late March. The modest portfolio growth of $8 000, or 0.5 per cent, maintains its value at around that achieved at the beginning of the year. [Chart] The limited growth this month largely reflects an increase in the value of my current equity holdings, in VAS and A200 and the Vanguard retail funds. This has outweighed a small decline in the value of Bitcoin and global shares. The value of the bond holdings also increased modestly, pushing them to their highest value since around early 2017. [Chart] There still appears to be an air of unreality around recent asset price increases and the broader economic context. Britain's Bank of England has on some indicators shown that the aftermath of the pandemic and lockdown represent the most challenging financial crisis in around 300 years. What is clear is that investor perceptions and fear around the coronavirus pandemic are a substantial ongoing force driving volatility in equity markets (pdf). A somewhat optimistic view is provided here that the recovery could look more like the recovery from a natural disaster, rather than a traditional recession. Yet there are few certainties on offer. Negative oil prices, and effective offers by US equity investors to bail out Hertz creditors at no cost appear to be signs of a financial system under significant strains. As this Reserve Bank article highlights, while some Australian households are well-placed to weather the storm ahead, the timing and severity of what lays ahead is an important unknown that will itself feed into changes in household wealth from here. Investments this month have been exclusively in the Australian shares exchange-traded fund (VAS) using Selfwealth.* This has been to bring my actual asset allocation more closely in line with the target split between Australian and global shares. A moving azimuth: falling spending continues Monthly expenses on the credit card have continued their downward trajectory across the past month. [Chart] The rolling average of monthly credit card spending is now at its lowest point over the period of the journey. This is despite the end of lockdown, and a slow resumption of some more normal aspects of spending. This has continued the brief period since April of the achievement of a notional and contingent kind of financial independence. The below chart illustrates this temporary state, setting out the degree to which portfolio distributions cover estimated total expenses, measured month to month. [Chart] There are two sources of volatility underlying its movement. The first is the level of expenses, which can vary, and the second is the fact that it is based on financial year distributions, which are themselves volatile. Importantly, the distributions over the last twelve months of this chart is only an estimate - and hence the next few weeks will affect the precision of this analysis across its last 12 observations. Estimating 2019-20 financial year portfolio distributions Since the beginning of the journey, this time of year usually has sense of waiting for events to unfold - in particular, finding out the level of half-year distributions to June. These represent the bulk of distributions, usually averaging 60-65 per cent of total distributions received. They are an important and tangible signpost of progress on the financial independence journey. This is no simple task, as distributions have varied in size considerably. A part of this variation has been the important role of sometimes large and lumpy capital distributions - which have made up between 30 to 48 per cent of total distributions in recent years, and an average of around 15 per cent across the last two decades. I have experimented with many different approaches, most of which have relied on averaging over multi-year periods to even out the 'peaks and troughs' of how market movements may have affected distributions. The main approaches have been:
An 'adjusted income' approach - stripping out the capital gains components of Vanguard funds to reach an estimate of underlying income generation, both across the entire investment period, and during the sharpest low of the Global Financial Crisis
A long-term asset class approach - relying on long-term historical data on averages of the income produced by various asset classes
A 'tax method' approach - this derives an income estimate as a percentage of the portfolio by drawing on taxable investment income totals from tax return records
Simple historical rolling average - this is a rolling three-year measure, based on the actual distributions record of the portfolio
Average distribution rate approach - this method uses a long-term average of annual distributions received as a percentage of the total portfolio since 1999
Each of these have their particular simplifications, advantages and drawbacks. Developing new navigation tools Over the past month I have also developed more fully an alternate 'model' for estimating returns. This simply derives a median value across a set of historical 'cents per unit' distribution data for June and December payouts for the Vanguard funds and exchange traded funds. These make up over 96 per cent of income producing portfolio assets. In other words, this model essentially assumes that each Vanguard fund and ETF owned pays out the 'average' level of distributions this half-year, with the average being based on distribution records that typically go back between 5 to 10 years. Mapping the distribution estimates The chart below sets out the estimate produced by each approach for the June distributions that are to come. [Chart] Some observations on these findings can be made. The lowest estimate is the 'adjusted GFC income' observation, which essentially assumes that the income for this period is as low as experienced by the equity and bond portfolio during the Global Financial Crisis. Just due to timing differences of the period observed, this seems to be a 'worst case' lower bound estimate, which I do not currently place significant weight on. Similarly, at the highest end, the 'average distribution rate' approach simply assumes June distributions deliver a distribution equal to the median that the entire portfolio has delivered since 1999. With higher interest rates, and larger fixed income holdings across much of that time, this seems an objectively unlikely outcome. Similarly, the delivery of exactly the income suggested by long-term averages measured across decades and even centuries would be a matter of chance, rather than the basis for rational expectations. Central estimates of the line of position This leaves the estimates towards the centre of the chart - estimates of between around $28 000 to $43 000 as representing the more likely range. I attach less weight to the historical three-year average due to the high contribution of distributed capital gains over that period of growth, where at least across equities some capital losses are likely to be in greater presence. My preferred central estimate is the model estimate (green) , as it is based in historical data directly from the investment vehicles rather than my own evolving portfolio. The data it is based on in some cases goes back to the Global Financial Crisis. This estimate is also quite close to the raw average of all the alternative approaches (red). It sits a little above the 'adjusted income' measure. None of these estimates, it should be noted, contain any explicit adjustment for the earnings and dividend reductions or delays arising from COVID-19. They may, therefore represent a modest over-estimate for likely June distributions, to the extent that these effects are more negative than those experienced on average across the period of the underlying data. These are difficult to estimate, but dividend reductions could easily be in the order of 20-30 per cent, plausibly lowering distributions to the $23 000 to $27 000 range. The recently announced forecast dividend for the Vanguard Australian Shares ETF (VAS) is, for example, the lowest in four years. As seen from chart above, there is a wide band of estimates, which grow wider still should capital gains be unexpectedly distributed from the Vanguard retail funds. These have represented a source of considerable volatility. Given this, it may seem fruitless to seek to estimate these forthcoming distributions, compared to just waiting for them to arrive. Yet this exercise helps by setting out reasoning and positions, before hindsight bias urgently arrives to inform me that I knew the right answer all along. It also potentially helps clearly 'reject' some models over time, if the predictions they make prove to be systematically incorrect. Progress Progress against the objective, and the additional measures I have reached is set out below. Measure Portfolio All Assets Portfolio objective – $2 180 000 (or $87 000 pa) 81.0% 109.4% Credit card purchases – $71 000 pa 98.8% 133.5% Total expenses – $89 000 pa 79.2% 106.9% Summary The current coronavirus conditions are affecting all aspects of the journey to financial independence - changing spending habits, leading to volatility in equity markets and sequencing risks, and perhaps dramatically altering the expected pattern of portfolio distributions. Although history can provide some guidance, there is simply no definitive way to know whether any or all of these changes will be fundamental and permanent alterations, or simply data points on a post-natural disaster path to a different post-pandemic set of conditions. There is the temptation to fit past crises imperfectly into the modern picture, as this Of Dollars and Data post illustrates well. Taking a longer 100 year view, this piece 'The Allegory of the Hawk and Serpent' is a reminder that our entire set of received truths about constructing a portfolio to survive for the long-term can be a product of a sample size of one - actual past history - and subject to recency bias. This month has felt like one of quiet routines, muted events compared to the past few months, and waiting to understand more fully the shape of the new. Nonetheless, with each new investment, or week of lower expenditure than implied in my FI target, the nature of the journey is incrementally changing - beneath the surface. Small milestones are being passed - such as over 40 per cent of my equity holdings being outside of the the Vanguard retail funds. Or these these retail funds - which once formed over 95 per cent of the portfolio - now making up less than half. With a significant part of the financial independence journey being about repeated small actions producing outsized results with time, the issue of maintaining good routines while exploring beneficial changes is real. Adding to the complexity is that embarking on the financial journey itself is likely to change who one is. This idea, of the difficulty or impossibility of knowing the preferences of a future self, is explored in a fascinating way in this Econtalk podcast episode with a philosophical thought experiment about vampires. It poses the question: perhaps we can never know ourselves at the destination? And yet, who would rationally choose ruin over any change? The post, links and full charts can be seen here.
Bitcoin's largest positive difficulty adjustment of 2020 and what it means for the price
This post was originally published on this siteThis post was originally published on this siteAs of 20 September, Bitcoin’s difficulty has been adjusted by ~11.35%, with the hash rate subsequently hitting a new ATH of 143m TH/s. This was the largest positive adjustment in the year 2020, and its implications might not be as bullish as one would expect. While an increase […]
To keep a steady block creation rate, Bitcoin creator Satoshi Nakamoto put in place a rule that updates the network difficulty every 2016 blocks, or approximately two weeks. According to Bitcoin Wisdom, the difficulty increase that took place today rose by 10.44. The last time the difficulty increased by more than 10 percent was on November 5, 2014, when the difficulty increased by 10.05 ... The increase of difficulty level by 14.95% is the highest since January 2018. Two weeks back, the difficulty rate of Bitcoin mining adjusted itself to accommodate many more miners. The algorithm for BTCUSD mining is such that it auto-adjusts every two weeks. The Bitcoin Hash rate--a measure of the amount of computation power channeled by miners to the network, is down 10 percent two days after the Bitcoin mining difficulty was increased by 3.62 percent on Oct 17. The Bitcoin Network Machine Often, the network hash rate falls whenever there is a positive readjustment.… Difficulty is re-calculated every 2016 blocks to ensure blocks are found every 10 minutes on average. As more computers attempt to mine Bitcoin Core (BTC) and increase the Hash Rate, the difficulty will increase. If the Hash Rate decreases, difficulty will decrease. difficulty = difficulty_1_target / current_target (target is a 256 bit number) difficulty_1_target can be different for various ways to measure difficulty. Traditionally, it represents a hash where the leading 32 bits are zero and the rest are one (this is known as "pool difficulty" or "pdiff"). The Bitcoin protocol represents targets as a ...
