Things to Consider When Starting a Bitcoin Mining Operation

How much does it cost to start a bitcoin mining operation

Let’s say I am thinking about buying 12,000 solar panels to mine bitcoin.

Putting $400M of Bitcoin on your company balance sheet

Also posted on my blog as usual. Read it there if you can, there are footnotes and inlined plots.
A couple of months ago, MicroStrategy (MSTR) had a spare $400M of cash which it decided to shift to Bitcoin (BTC).
Today we'll discuss in excrutiating detail why this is not a good idea.
When a company has a pile of spare money it doesn't know what to do with, it'll normally do buybacks or start paying dividends. That gives the money back to the shareholders, and from an economic perspective the money can get better invested in other more promising companies. If you have a huge pile of of cash, you probably should be doing other things than leave it in a bank account to gather dust.
However, this statement from MicroStrategy CEO Michael Saylor exists to make it clear he's buying into BTC for all the wrong reasons:
“This is not a speculation, nor is it a hedge. This was a deliberate corporate strategy to adopt a bitcoin standard.”
Let's unpack it and jump into the economics Bitcoin:

Is Bitcoin money?

No.
Or rather BTC doesn't act as money and there's no serious future path for BTC to become a form of money. Let's go back to basics. There are 3 main economic problems money solves:
1. Medium of Exchange. Before money we had to barter, which led to the double coincidence of wants problem. When everyone accepts the same money you can buy something from someone even if they don't like the stuff you own.
As a medium of exchange, BTC is not good. There are significant transaction fees and transaction waiting times built-in to BTC and these worsen the more popular BTC get.
You can test BTC's usefulness as a medium of exchange for yourself right now: try to order a pizza or to buy a random item with BTC. How many additional hurdles do you have to go through? How many fewer options do you have than if you used a regular currency? How much overhead (time, fees) is there?
2. Unit of Account. A unit of account is what you compare the value of objects against. We denominate BTC in terms of how many USD they're worth, so BTC is a unit of account presently. We can say it's because of lack of adoption, but really it's also because the market value of BTC is so volatile.
If I buy a $1000 table today or in 2017, it's roughly a $1000 table. We can't say that a 0.4BTC table was a 0.4BTC table in 2017. We'll expand on this in the next point:
3. Store of Value. When you create economic value, you don't want to be forced to use up the value you created right away.
For instance, if I fix your washing machine and you pay me in avocados, I'd be annoyed. I'd have to consume my payment before it becomes brown, squishy and disgusting. Avocado fruit is not good money because avocadoes loses value very fast.
On the other hand, well-run currencies like the USD, GBP, CAD, EUR, etc. all lose their value at a low and most importantly fairly predictible rate. Let's look at the chart of the USD against BTC
While the dollar loses value at a predictible rate, BTC is all over the place, which is bad.
One important use money is to write loan contracts. Loans are great. They let people spend now against their future potential earnings, so they can buy houses or start businesses without first saving up for a decade. Loans are good for the economy.
If you want to sign something that says "I owe you this much for that much time" then you need to be able to roughly predict the value of the debt in at the point in time where it's due.
Otherwise you'll have a hard time pricing the risk of the loan effectively. This means that you need to charge higher interests. The risk of making a loan in BTC needs to be priced into the interest of a BTC-denominated loan, which means much higher interest rates. High interests on loans are bad, because buying houses and starting businesses are good things.

BTC has a fixed supply, so these problems are built in

Some people think that going back to a standard where our money was denominated by a stock of gold (the Gold Standard) would solve economic problems. This is nonsense.
Having control over supply of your currency is a good thing, as long as it's well run.
See here
Remember that what is desirable is low variance in the value, not the value itself. When there are wild fluctuations in value, it's hard for money to do its job well.
Since the 1970s, the USD has been a fiat money with no intrinsic value. This means we control the supply of money.
Let's look at a classic poorly drawn econ101 graph
The market price for USD is where supply meets demand. The problem with a currency based on an item whose supply is fixed is that the price will necessarily fluctuate in response to changes in demand.
Imagine, if you will, that a pandemic strikes and that the demand for currency takes a sharp drop. The US imports less, people don't buy anything anymore, etc. If you can't print money, you get deflation, which is worsens everything. On the other hand, if you can make the money printers go brrrr you can stabilize the price
Having your currency be based on a fixed supply isn't just bad because in/deflation is hard to control.
It's also a national security risk...
The story of the guy who crashed gold prices in North Africa
In the 1200s, Mansa Munsa, the emperor of the Mali, was rich and a devout Muslim and wanted everyone to know it. So he embarked on a pilgrimage to make it rain all the way to Mecca.
He in fact made it rain so hard he increased the overall supply of gold and unintentionally crashed gold prices in Cairo by 20%, wreaking an economic havoc in North Africa that lasted a decade.
This story is fun, the larger point that having your inflation be at the mercy of foreign nations is an undesirable attribute in any currency. The US likes to call some countries currency manipulators, but this problem would be serious under a gold standard.

Currencies are based on trust

Since the USD is based on nothing except the US government's word, how can we trust USD not to be mismanaged?
The answer is that you can probably trust the fed until political stooges get put in place. Currently, the US's central bank managing the USD, the Federal Reserve (the Fed for friends & family), has administrative authority. The fed can say "no" to dumb requests from the president.
People who have no idea what the fed does like to chant "audit the fed", but the fed is already one of the best audited US federal entities. The transcripts of all their meetings are out in the open. As is their balance sheet, what they plan to do and why. If the US should audit anything it's the Department of Defense which operates without any accounting at all.
It's easy to see when a central bank will go rogue: it's when political yes-men are elected to the board.
For example, before printing themselves into hyperinflation, the Venezuelan president appointed a sociologist who publicly stated “Inflation does not exist in real life” and instead is a made up capitalist lie. Note what happened mere months after his gaining control over the Venezuelan currency
This is a key policy. One paper I really like, Sargent (1984) "The end of 4 big inflations" states:
The essential measures that ended hyperinflation in each of Germany,Austria, Hungary, and Poland were, first, the creation of an independentcentral bank that was legally committed to refuse the government'sdemand or additional unsecured credit and, second, a simultaneousalteration in the fiscal policy regime.
In english: *hyperinflation stops when the central bank can say "no" to the government."
The US Fed, like other well good central banks, is run by a bunch of nerds. When it prints money, even as aggressively as it has it does so for good reasons. You can see why they started printing on March 15th as the COVID lockdowns started:
The Federal Reserve is prepared to use its full range of tools to support the flow of credit to households and businesses and thereby promote its maximum employment and price stability goals.
In english: We're going to keep printing and lowering rates until jobs are back and inflation is under control. If we print until the sun is blotted out, we'll print in the shade.

BTC is not gold

Gold is a good asset for doomsday-preppers. If society crashes, gold will still have value.
How do we know that?
Gold has held value throughout multiple historic catastrophes over thousands of years. It had value before and after the Bronze Age Collapse, the Fall of the Western Roman Empire and Gengis Khan being Gengis Khan.
Even if you erased humanity and started over, the new humans would still find gold to be economically valuable. When Europeans d̶i̶s̶c̶o̶v̶e̶r̶e̶d̶ c̶o̶n̶q̶u̶e̶r̶e̶d̶ g̶e̶n̶o̶c̶i̶d̶e̶d̶ went to America, they found gold to be an important item over there too. This is about equivalent to finding humans on Alpha-Centauri and learning that they think gold is a good store of value as well.
Some people are puzzled at this: we don't even use gold for much! But it has great properties:
First, gold is hard to fake and impossible to manufacture. This makes it good to ascertain payment.
Second, gold doesnt react to oxygen, so it doesn't rust or tarnish. So it keeps value over time unlike most other materials.
Last, gold is pretty. This might sound frivolous, and you may not like it, but jewelry has actual value to humans.
It's no coincidence if you look at a list of the wealthiest families, a large number of them trade in luxury goods.
To paraphrase Veblen humans have a profound desire to signal social status, for the same reason peacocks have unwieldy tails. Gold is a great way to achieve that.
On the other hand, BTC lacks all these attributes. Its value is largely based on common perception of value. There are a few fundamental drivers of demand:
Apart from these, it's hard to argue that BTC will retain value throughout some sort of economic catastrophe.

BTC is really risky

One last statement from Michael Saylor I take offense to is this:
“We feel pretty confident that Bitcoin is less risky than holding cash, less risky than holding gold,” MicroStrategy CEO said in an interview
"BTC is less risky than holding cash or gold long term" is nonsense. We saw before that BTC is more volatile on face value, and that as long as the Fed isn't run by spider monkeys stacked in a trench coat, the inflation is likely to be within reasonable bounds.
But on top of this, BTC has Abrupt downside risks that normal currencies don't. Let's imagine a few:

Blockchain solutions are fundamentally inefficient

Blockchain was a genius idea. I still marvel at the initial white paper which is a great mix of economics and computer science.
That said, blockchain solutions make large tradeoffs in design because they assume almost no trust between parties. This leads to intentionally wasteful designs on a massive scale.
The main problem is that all transactions have to be validated by expensive computational operations and double checked by multiple parties. This means waste:
Many design problems can be mitigated by various improvements over BTC, but it remains that a simple database always works better than a blockchain if you can trust the parties to the transaction.

A Detailed Summary of Every Single Reason Why I am Bullish on Ethereum

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself on the DeFi Pulse website.

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA player Spencer Dinwiddie tokenized his own NBA contract.)

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (Jitsi for the zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

TL;DR:

FYI: yesterday I got trolled by someone using a password from a hacked account, and fishing for a payout. The password was a simple one I used on a few old accounts. It was really a blessing, because it finally motivated me to set up 1Password, and start migrating my 400+ accts/logins to it.

In case any user has a related question, you'll know why... The subject of the email was my old password. Here's the body:
I know [xxxx] is one of your password on day of hack.
Lets get directly to the point.
Not one person has paid me to check about you.
You do not know me and you're probably thinking why you are getting this email?
in fact, i actually placed a malware on the adult vids (adult porn) website and you know what, you visited this site to experience fun (you know what i mean).
When you were viewing videos, your browser started out operating as a RDP having a key logger which provided me with accessibility to your display and web cam.
immediately after that, my malware obtained every one of your contacts from your Messenger, FB, as well as email account.
after that i created a double-screen video. 1st part shows the video you were viewing (you have a nice taste omg), and 2nd part displays the recording of your cam, and its you.
Best solution would be to pay me $1007.
We are going to refer to it as a donation. in this situation, i most certainly will without delay remove your video.
My -BTC -address: [wishful thinking]
[case SeNSiTiVe, copy & paste it]
You could go on your life like this never happened and you will not ever hear back again from me.
You'll make the payment via Bitcoin (if you do not know this, search 'how to buy bitcoin' in Google).
if you are planning on going to the law, surely, this e-mail can not be traced back to me, because it's hacked too.
I have taken care of my actions. i am not looking to ask you for a lot, i simply want to be paid.
if i do not receive the bitcoin;, i definitely will send out your video recording to all of your contacts including friends and family, co-workers, and so on.
Nevertheless, if i do get paid, i will destroy the recording immediately.
If you need proof, reply with Yeah then i will send out your video recording to your 8 friends.
it's a nonnegotiable offer and thus please don't waste mine time & yours by replying to this message.

None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!
Oh, and if you think that DeFi was just a fad and the bubble has popped, guess again! Total value locked in DeFi is currently at an all time high. Don’t believe me? Find out for yourself at: https://defipulse.com

NFTs and tokeniation

NFTs or “Non-Fungible Tokens” - despite the name which may confuse a layman - are a basic concept. They are unique tokens with their own unique attributes. This allows you to create digital art, human readable names for your ETH address (see ENS names and unstoppable domains), breedable virtual collectible creatures like crypto kitties, ownable in game assets like Gods Unchained cards or best of all in my opinion, tokenised ownership of real world assets which can even be split into pieces (this doesn’t necessarily require an NFT. Fungible tokens can be/are used for some of the following use cases). This could be tokenised ownership of real estate (see RealT), tokenised ownership of stocks, bonds and other financial assets (which by the way makes them tradable 24/7 and divisible unlike through the traditional system) or even tokenised ownership of the future income of a celebrity or athlete (see when NBA Star Spencer Dinwiddie Tokenized His Own NBA Contract.

Institutional Adoption

Ethereum is by far the most widely adopted blockchain by enterprises. Ethereum’s Enterprise Ethereum Alliance (EEA) is the largest blockchain-enterprise partnership program and Ethereum is by far the most frequently leveraged blockchain for proof of concepts and innovation in the blockchain space by enterprises. Meanwhile, there are protocols like the Baseline protocol which is a shared framework which allows enterprises to use Ethereum as a common frame of reference and a base settlement layer without having to give up privacy when settling on the public Ethereum mainnet. This framework makes adopting Ethereum much easier for other enterprises.

Institutional Investment

One of Bitcoin’s biggest things it has going for it right now is the growing institutional investment. In case you were wondering, Ethereum has this too! Grayscale offers investment in the cryptocurrency space for financial institutions and their Ethereum fund has already locked up more than 2% of the total supply of ETH. Not only this, but as businesses transact on Ethereum and better understand it, not only will they buy up ETH to pay for their transactions, but they will also realise that much like Bitcoin, Ethereum is a scarce asset. Better yet, a scarce asset which offers yield. As a result, I expect to see companies having ETH holdings become the norm just like how Bitcoin is becoming more widespread on companies’ balance sheets.

The state of global markets

With asset prices in almost every asset class at or near all-time highs and interest rates lower than ever and even negative in some cases, there really aren’t many good opportunities in the traditional financial system right now. Enter crypto - clearly the next evolution of financial services (as I explained in the section on DeFi earlier in this post), with scarce assets built in at the protocol layer, buying BTC or ETH is a lot like buying shares in TCP/IP in 1990 (that is if the underlying protocols of the internet could be invested in which they couldn’t). Best of all, major cryptos are down from their all-time highs anywhere between 35% for BTC or 70% for ETH and much more for many altcoins. This means that they can significantly appreciate in value before entering uncharted, speculative bubble territory.
While of course we could fall dramatically at any moment in the current macro financial conditions, as a longer term play, crypto is very alluring. The existing financial system has shown that it is in dire need of replacing and the potential replacement has started rearing its head in the form of crypto and DeFi.

Improvements in user onboarding and abstracting away complexity

Ethereum has started making huge leaps forward in terms of usability for the end user. We now have ENS names and unstoppable domains which allow you to send ETH to yournamehere.ETH or TrickyTroll.crypto (I don’t actually have that domain, that’s just an example). No longer do you have to check every character of your ugly hexadecimal 0x43AB96D… ETH address to ensure you’re sending your ETH to the right person. We also have smart contract wallets like Argent wallet or the Gnosis safe. These allow for users to access their wallets and interact with DeFi self-custodially from an app on their phone without having to record a private key or recovery phrase. Instead, they offer social recovery and their UI is straight forward enough for anyone who uses a smart phone to understand. Finally, for the more experienced users, DApps like Uniswap have pretty, super easy to use graphical user interfaces and can be used by anyone who knows how to run and use a browser extension like Metamask.

The lack of an obvious #1 ETH killer

One of Ethereum’s biggest threats is for it to be overthrown by a so-called “Ethereum killer” blockchain which claims to do everything Ethereum can do and sometimes more. While there are competitors which are each formidable to a certain extent such as Polkadot, Cardano and EOS, each have their own weaknesses. For example, Polkadot and Cardano are not fully operational yet and EOS is much more centralised than Ethereum. As a result, none of these competitors have any significant network effects just yet relative to the behemoth which is Ethereum. This doesn’t mean that these projects aren’t a threat. In fact, I am sure that projects like Polkadot (which is more focused on complimenting Ethereum than killing it) will take a slice out of Ethereum’s pie. However, I am still very confident that Ethereum will remain on top due to the lack of a clear number 2 smart contract platform. Since none of these ETH killers stands out as the second place smart contract platform, it makes it much harder for one project to create a network effect which even begins to threaten Ethereum’s dominance. This leads me onto my next reason - network effects.

Network effects

This is another topic which I made a previous post on. The network effect is why Bitcoin is still the number one cryptocurrency and by such a long way. Bitcoin is not the most technologically advanced cryptocurrency. However, it has the most widespread name recognition and the most adoption in most metrics (ETH beats in in some metrics these days). The network effect is also why most people use Zoom and Facebook messengeWhatsApp despite the existence of free, private, end to end encrypted alternatives which have all the same features (https://meet.jit.si/ for zoom alternative and Signal for the private messenger app. I highly recommend both. Let’s get their network effects going!). It is the same for Bitcoin. People don’t want to have to learn about or set up a wallet for alternative options. People like what is familiar and what other people use. Nobody wants to be “that guy” who makes you download yet another app and account you have to remember the password/private key for. In the same way, Enterprises don’t want to have to create a bridge between their existing systems and a dozen different blockchains. Developers don’t want to have to create DeFi money legos from scratch on a new chain if they can just plug in to existing services like Uniswap. Likewise, users don’t want to have to download another browser extension to use DApps on another chain if they already use Ethereum. I know personally I have refrained from investing in altcoins because I would have to install another app on my hardware wallet or remember another recovery phrase.
Overthrowing Ethereum’s network effect is one hell of a big task these days. Time is running out for the ETH killers.

Ethereum is the most decentralised and provably neutral smart contract platform

Ethereum is also arguably the most decentralised and provably neutral smart contract platform (except for maybe Ethereum Classic on the neutrality part). Unlike some smart contract platforms, you can’t round up everyone at the Ethereum Foundation or any select group of people and expect to be able to stop the network. Not only this, but the Ethereum foundation doesn’t have the ability to print more ETH or push through changes as they wish like some people would lead you on to believe. The community would reject detrimental EIPs and hard fork. Ever since the DAO hack, the Ethereum community has made it clear that it will not accept EIPs which attempt to roll back the chain even to recover hacked funds (see EIP-999).
Even if governments around the world wanted to censor the Ethereum blockchain, under ETH 2.0’s proof of stake, it would be incredibly costly and would require a double digit percentage of the total ETH supply, much of which would be slashed (meaning they would lose it) as punishment for running dishonest validator nodes. This means that unlike with proof of work where a 51% attacker can keep attacking the network, under proof of stake, an attacker can only perform the attack a couple of times before they lose all of their ETH. This makes attacks much less financially viable than it is on proof of work chains. Network security is much more than what I laid out above and I am far from an expert but the improved resistance to 51% attacks which PoS provides is significant.
Finally, with the US dollar looking like it will lose its reserve currency status and the existing wire transfer system being outdated, superpowers like China won’t want to use US systems and the US won’t want to use a Chinese system. Enter Ethereum, the provably neutral settlement layer where the USA and China don’t have to trust each other or each other’s banks because they can trust Ethereum. While it may sound like a long shot, it does make sense if Ethereum hits a multi-trillion dollar market cap that it is the most secure and neutral way to transfer value between these adversaries. Not to mention if much of the world’s commerce were to be settled in the same place - on Ethereum - then it would make sense for governments to settle on the same platform.

ETH distribution is decentralised

Thanks to over 5 years of proof of work - a system where miners have to sell newly minted ETH to pay for electricity costs - newly mined ETH has found its way into the hands of everyday people who buy ETH off miners selling on exchnages. As pointed out by u/AdamSC1 in his analysis of the top 10K ETH addresses (I highly recommend reading this if you haven’t already), the distribution of ETH is actually slightly more decentralised than Bitcoin with the top 10,000 ETH wallets holding 56.70% of ETH supply compared to the top 10,000 Bitcoin wallets which hold 57.44% of the Bitcoin supply. This decentralised distribution means that the introduction of staking won’t centralise ETH in the hands of a few wallets who could then control the network. This is an advantage for ETH which many proof of stake ETH killers will never have as they never used PoW to distribute funds widely throughout the community and these ETH killers often did funding rounds giving large numbers of tokens to VC investors.

The community

Finally, while I may be biased, I think that Ethereum has the friendliest community. Anecdotally, I find that the Ethereum developer community is full of forward thinking people who want to make the world a better place and build a better future, many of whom are altruistic and don’t always act in their best interests. Compare this to the much more conservative, “at least we’re safe while the world burns” attitude which many Bitcoiners have. I don’t want to generalise too much here as the Bitcoin community is great too and there are some wonderful people there. But the difference is clear if you compare the daily discussion of Bitcoin to the incredibly helpful and welcoming daily discussion of EthFinance who will happily answer your noob questions without calling you an idiot and telling you to do you own research (there are plenty more examples in any of the daily threads). Or the very helpful folks over at EthStaker who will go out of their way to help you set up an ETH 2.0 staking node on the testnets (Shoutout to u/superphiz who does a lot of work over in that sub!). Don’t believe me? Head over to those subs and see for yourself.
Please don’t hate on me if you disagree about which project has the best community, it is just my very biased personal opinion and I respect your opinion if you disagree! :)

TL;DR:

submitted by Tricky_Troll to ethtrader [link] [comments]

A detailed summary of every reason why I am bullish on ETH.

The following will be a list of the many reasons why I hold and am extremely bullish on ETH.

This is an extremely long post. If you just want the hopium without the detail, read the TL;DR at the bottom.

ETH 2.0

As we all know, ETH 2.0 phase 0 is right around the corner. This will lock up ETH and stakers will earn interest on their ETH in return for securing the network. Next comes phase 1 where the ETH 2 shards are introduced, shards are essentially parallel blockchains which are each responsible for a different part of Ethereum’s workload, think of it like a multi-core processor vs a single core processor. During phase 1, these shards will only act as data availability layers and won’t actually process transactions yet. However, their data can be utilised by the L2 scaling solution, rollups, increasing Ethereum’s throughput in transactions per second up to 100,000 TPS.
After phase 1 comes phase 1.5 which will move the ETH 1.0 chain into an ETH 2 shard and Ethereum will be fully secured by proof of stake. This means that ETH issuance will drop from around 5% per year to less than 1% and with EIP-1559, ETH might become a deflationary asset, but more on that later.
Finally, with ETH 2.0 phase two, each shard will be fully functional chains. With 64 of them, we can expect the base layer of Ethereum to scale around 64x, not including the massive scaling which comes from layer 2 scaling solutions like rollups as previously mentioned.
While the scaling benefits and ETH issuance reduction which comes with ETH 2.0 will be massive, they aren’t the only benefits. We also get benefits such as increased security from PoS compared to PoW, a huge energy efficiency improvement due to the removal of PoW and also the addition of eWASM which will allow contracts to be programmed in a wide range of programming languages, opening the floodgates for millions of web devs who want to be involved in Ethereum but don’t know Ethereum’s programming language, Solidity.

EIP-1559 and ETH scarcity

As I covered in a previous post of mine, ETH doesn’t have a supply cap like Bitcoin. Instead, it has a monetary policy of “minimum viable issuance”, not only is this is a good thing for network security, but with the addition of EIP-1559, it leaves the door open to the possibility of ETH issuance going negative. In short, EIP-1559 changes the fee market to make transaction prices more efficient (helping to alleviate high gas fees!) by burning a variable base fee which changes based on network usage demand rather than using a highest bidder market where miners simply include who pays them the most. This will result in most of the ETH being paid in transaction fees being burned. As of late, the amount which would be burned if EIP-1559 was in Ethereum right now would make ETH a deflationary asset!

Layer 2 Scaling

In the mean time while we are waiting for ETH 2.0, layer 2 scaling is here. Right now, projects such as Deversifi or Loopring utilise rollups to scale to thousands of tx/s on their decentralised exchange platforms or HoneySwap which uses xDai to offer a more scalable alternative to UniSwap. Speaking of which, big DeFi players like UniSwap and Synthetix are actively looking into using optimistic rollups to scale while maintaining composability between DeFi platforms. The most bullish thing about L2 scaling is all of the variety of options. Here’s a non exhaustive list of Ethereum L2 scaling solutions: - Aztec protocol (L2 scaling + privacy!) - ZKSync - Loopring - Raiden - Arbitrum Rollups - xDai - OMGNetwork - Matic - FuelLabs - Starkware - Optimism - Celer Network - + Many more

DeFi and Composability

If you’re reading this, I am sure you are aware of the phenomena which is Decentralised Finance (DeFi or more accurately, open finance). Ethereum is the first platform to offer permissionless and immutable financial services which when interacting with each other, lead to unprecedented composability and innovation in financial applications. A whole new world of possibilities are opening up thanks to this composability as it allows anyone to take existing pieces of open source code from other DeFi projects, put them together like lego pieces (hence the term money legos) and create something the world has never seen before. None of this was possible before Ethereum because typically financial services are heavily regulated and FinTech is usually proprietary software, so you don’t have any open source lego bricks to build off and you have to build everything you need from scratch. That is if what you want to do is even legal for a centralised institution!

Technical: Taproot: Why Activate?

This is a follow-up on https://old.reddit.com/Bitcoin/comments/hqzp14/technical_the_path_to_taproot_activation/
Taproot! Everybody wants it!! But... you might ask yourself: sure, everybody else wants it, but why would I, sovereign Bitcoin HODLer, want it? Surely I can be better than everybody else because I swapped XXX fiat for Bitcoin unlike all those nocoiners?
And it is important for you to know the reasons why you, o sovereign Bitcoiner, would want Taproot activated. After all, your nodes (or the nodes your wallets use, which if you are SPV, you hopefully can pester to your wallet vendoimplementor about) need to be upgraded in order for Taproot activation to actually succeed instead of becoming a hot sticky mess.
First, let's consider some principles of Bitcoin.
I'm sure most of us here would agree that the above are very important principles of Bitcoin and that these are principles we would not be willing to remove. If anything, we would want those principles strengthened (especially the last one, financial privacy, which current Bitcoin is only sporadically strong with: you can get privacy, it just requires effort to do so).
So, how does Taproot affect those principles?

Taproot and Your /Coins

Most HODLers probably HODL their coins in singlesig addresses. Sadly, switching to Taproot would do very little for you (it gives a mild discount at spend time, at the cost of a mild increase in fee at receive time (paid by whoever sends to you, so if it's a self-send from a P2PKH or bech32 address, you pay for this); mostly a wash).
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash, so the Taproot output spends 12 bytes more; spending from a P2WPKH requires revealing a 32-byte public key later, which is not needed with Taproot, and Taproot signatures are about 9 bytes smaller than P2WPKH signatures, but the 32 bytes plus 9 bytes is divided by 4 because of the witness discount, so it saves about 11 bytes; mostly a wash, it increases blockweight by about 1 virtual byte, 4 weight for each Taproot-output-input, compared to P2WPKH-output-input).
However, as your HODLings grow in value, you might start wondering if multisignature k-of-n setups might be better for the security of your savings. And it is in multisignature that Taproot starts to give benefits!
Taproot switches to using Schnorr signing scheme. Schnorr makes key aggregation -- constructing a single public key from multiple public keys -- almost as trivial as adding numbers together. "Almost" because it involves some fairly advanced math instead of simple boring number adding, but hey when was the last time you added up your grocery list prices by hand huh?
With current P2SH and P2WSH multisignature schemes, if you have a 2-of-3 setup, then to spend, you need to provide two different signatures from two different public keys. With Taproot, you can create, using special moon math, a single public key that represents your 2-of-3 setup. Then you just put two of your devices together, have them communicate to each other (this can be done airgapped, in theory, by sending QR codes: the software to do this is not even being built yet, but that's because Taproot hasn't activated yet!), and they will make a single signature to authorize any spend from your 2-of-3 address. That's 73 witness bytes -- 18.25 virtual bytes -- of signatures you save!
And if you decide that your current setup with 1-of-1 P2PKH / P2WPKH addresses is just fine as-is: well, that's the whole point of a softfork: backwards-compatibility; you can receive from Taproot users just fine, and once your wallet is updated for Taproot-sending support, you can send to Taproot users just fine as well!
(P2WPKH and P2WSH -- SegWit v0 -- addresses start with bc1q; Taproot -- SegWit v1 --- addresses start with bc1p, in case you wanted to know the difference; in bech32 q is 0, p is 1)
Now how about HODLers who keep all, or some, of their coins on custodial services? Well, any custodial service worth its salt would be doing at least 2-of-3, or probably something even bigger, like 11-of-15. So your custodial service, if it switched to using Taproot internally, could save a lot more (imagine an 11-of-15 getting reduced from 11 signatures to just 1!), which --- we can only hope! --- should translate to lower fees and better customer service from your custodial service!
So I think we can say, very accurately, that the Bitcoin principle --- that YOU are in control of your money --- can only be helped by Taproot (if you are doing multisignature), and, because P2PKH and P2WPKH remain validly-usable addresses in a Taproot future, will not be harmed by Taproot. Its benefit to this principle might be small (it mostly only benefits multisignature users) but since it has no drawbacks with this (i.e. singlesig users can continue to use P2WPKH and P2PKH still) this is still a nice, tidy win!
(even singlesig users get a minor benefit, in that multisig users will now reduce their blockchain space footprint, so that fees can be kept low for everybody; so for example even if you have your single set of private keys engraved on titanium plates sealed in an airtight box stored in a safe buried in a desert protected by angry nomads riding giant sandworms because you're the frickin' Kwisatz Haderach, you still gain some benefit from Taproot)
And here's the important part: if P2PKH/P2WPKH is working perfectly fine with you and you decide to never use Taproot yourself, Taproot will not affect you detrimentally. First do no harm!

Taproot and Your Contracts

No one is an island, no one lives alone. Give and you shall receive. You know: by trading with other people, you can gain expertise in some obscure little necessity of the world (and greatly increase your productivity in that little field), and then trade the products of your expertise for necessities other people have created, all of you thereby gaining gains from trade.
So, contracts, which are basically enforceable agreements that facilitate trading with people who you do not personally know and therefore might not trust.
Let's start with a simple example. You want to buy some gewgaws from somebody. But you don't know them personally. The seller wants the money, you want their gewgaws, but because of the lack of trust (you don't know them!! what if they're scammers??) neither of you can benefit from gains from trade.
However, suppose both of you know of some entity that both of you trust. That entity can act as a trusted escrow. The entity provides you security: this enables the trade, allowing both of you to get gains from trade.
In Bitcoin-land, this can be implemented as a 2-of-3 multisignature. The three signatories in the multisgnature would be you, the gewgaw seller, and the escrow. You put the payment for the gewgaws into this 2-of-3 multisignature address.
Now, suppose it turns out neither of you are scammers (whaaaat!). You receive the gewgaws just fine and you're willing to pay up for them. Then you and the gewgaw seller just sign a transaction --- you and the gewgaw seller are 2, sufficient to trigger the 2-of-3 --- that spends from the 2-of-3 address to a singlesig the gewgaw seller wants (or whatever address the gewgaw seller wants).
But suppose some problem arises. The seller gave you gawgews instead of gewgaws. Or you decided to keep the gewgaws but not sign the transaction to release the funds to the seller. In either case, the escrow is notified, and if it can sign with you to refund the funds back to you (if the seller was a scammer) or it can sign with the seller to forward the funds to the seller (if you were a scammer).
Taproot helps with this: like mentioned above, it allows multisignature setups to produce only one signature, reducing blockchain space usage, and thus making contracts --- which require multiple people, by definition, you don't make contracts with yourself --- is made cheaper (which we hope enables more of these setups to happen for more gains from trade for everyone, also, moon and lambos).
(technology-wise, it's easier to make an n-of-n than a k-of-n, making a k-of-n would require a complex setup involving a long ritual with many communication rounds between the n participants, but an n-of-n can be done trivially with some moon math. You can, however, make what is effectively a 2-of-3 by using a three-branch SCRIPT: either 2-of-2 of you and seller, OR 2-of-2 of you and escrow, OR 2-of-2 of escrow and seller. Fortunately, Taproot adds a facility to embed a SCRIPT inside a public key, so you can have a 2-of-2 Taprooted address (between you and seller) with a SCRIPT branch that can instead be spent with 2-of-2 (you + escrow) OR 2-of-2 (seller + escrow), which implements the three-branched SCRIPT above. If neither of you are scammers (hopefully the common case) then you both sign using your keys and never have to contact the escrow, since you are just using the escrow public key without coordinating with them (because n-of-n is trivial but k-of-n requires setup with communication rounds), so in the "best case" where both of you are honest traders, you also get a privacy boost, in that the escrow never learns you have been trading on gewgaws, I mean ewww, gawgews are much better than gewgaws and therefore I now judge you for being a gewgaw enthusiast, you filthy gewgawer).

Taproot and Your Contracts, Part 2: Cryptographic Boogaloo

Now suppose you want to buy some data instead of things. For example, maybe you have some closed-source software in trial mode installed, and want to pay the developer for the full version. You want to pay for an activation code.
This can be done, today, by using an HTLC. The developer tells you the hash of the activation code. You pay to an HTLC, paying out to the developer if it reveals the preimage (the activation code), or refunding the money back to you after a pre-agreed timeout. If the developer claims the funds, it has to reveal the preimage, which is the activation code, and you can now activate your software. If the developer does not claim the funds by the timeout, you get refunded.
And you can do that, with HTLCs, today.
Of course, HTLCs do have problems:
Fortunately, with Schnorr (which is enabled by Taproot), we can now use the Scriptless Script constuction by Andrew Poelstra. This Scriptless Script allows a new construction, the PTLC or Pointlocked Timelocked Contract. Instead of hashes and preimages, just replace "hash" with "point" and "preimage" with "scalar".
Or as you might know them: "point" is really "public key" and "scalar" is really a "private key". What a PTLC does is that, given a particular public key, the pointlocked branch can be spent only if the spender reveals the private key of the given public key to you.
Another nice thing with PTLCs is that they are deniable. What appears onchain is just a single 2-of-2 signature between you and the developemanufacturer. It's like a magic trick. This signature has no special watermarks, it's a perfectly normal signature (the pledge). However, from this signature, plus some datta given to you by the developemanufacturer (known as the adaptor signature) you can derive the private key of a particular public key you both agree on (the turn). Anyone scraping the blockchain will just see signatures that look just like every other signature, and as long as nobody manages to hack you and get a copy of the adaptor signature or the private key, they cannot get the private key behind the public key (point) that the pointlocked branch needs (the prestige).
(Just to be clear, the public key you are getting the private key from, is distinct from the public key that the developemanufacturer will use for its funds. The activation key is different from the developer's onchain Bitcoin key, and it is the activation key whose private key you will be learning, not the developer's/manufacturer's onchain Bitcoin key).
So:
Taproot lets PTLCs exist onchain because they enable Schnorr, which is a requirement of PTLCs / Scriptless Script.
(technology-wise, take note that Scriptless Script works only for the "pointlocked" branch of the contract; you need normal Script, or a pre-signed nLockTimed transaction, for the "timelocked" branch. Since Taproot can embed a script, you can have the Taproot pubkey be a 2-of-2 to implement the Scriptless Script "pointlocked" branch, then have a hidden script that lets you recover the funds with an OP_CHECKLOCKTIMEVERIFY after the timeout if the seller does not claim the funds.)

Quantum Quibbles!

Now if you were really paying attention, you might have noticed this parenthetical:
(technical details: a Taproot output is 1 version byte + 32 byte public key, while a P2WPKH (bech32 singlesig) output is 1 version byte + 20 byte public key hash...)
So wait, Taproot uses raw 32-byte public keys, and not public key hashes? Isn't that more quantum-vulnerable??
Well, in theory yes. In practice, they probably are not.
It's not that hashes can be broken by quantum computes --- they're still not. Instead, you have to look at how you spend from a P2WPKH/P2PKH pay-to-public-key-hash.
When you spend from a P2PKH / P2WPKH, you have to reveal the public key. Then Bitcoin hashes it and checks if this matches with the public-key-hash, and only then actually validates the signature for that public key.
So an unconfirmed transaction, floating in the mempools of nodes globally, will show, in plain sight for everyone to see, your public key.
(public keys should be public, that's why they're called public keys, LOL)
And if quantum computers are fast enough to be of concern, then they are probably fast enough that, in the several minutes to several hours from broadcast to confirmation, they have already cracked the public key that is openly broadcast with your transaction. The owner of the quantum computer can now replace your unconfirmed transaction with one that pays the funds to itself. Even if you did not opt-in RBF, miners are still incentivized to support RBF on RBF-disabled transactions.
So the extra hash is not as significant a protection against quantum computers as you might think. Instead, the extra hash-and-compare needed is just extra validation effort.
Further, if you have ever, in the past, spent from the address, then there exists already a transaction indelibly stored on the blockchain, openly displaying the public key from which quantum computers can derive the private key. So those are still vulnerable to quantum computers.
For the most part, the cryptographers behind Taproot (and Bitcoin Core) are of the opinion that quantum computers capable of cracking Bitcoin pubkeys are unlikely to appear within a decade or two.
So:
For now, the homomorphic and linear properties of elliptic curve cryptography provide a lot of benefits --- particularly the linearity property is what enables Scriptless Script and simple multisignature (i.e. multisignatures that are just 1 signature onchain). So it might be a good idea to take advantage of them now while we are still fairly safe against quantum computers. It seems likely that quantum-safe signature schemes are nonlinear (thus losing these advantages).

Discussions About Taproot Activation

submitted by almkglor to Bitcoin [link] [comments]

Technical: The Path to Taproot Activation

Taproot! Everybody wants to have it, somebody wants to make it, nobody knows how to get it!
(If you are asking why everybody wants it, see: Technical: Taproot: Why Activate?)
(Pedants: I mostly elide over lockin times)
Briefly, Taproot is that neat new thing that gets us:
So yes, let's activate taproot!

The SegWit Wars

The biggest problem with activating Taproot is PTSD from the previous softfork, SegWit. Pieter Wuille, one of the authors of the current Taproot proposal, has consistently held the position that he will not discuss activation, and will accept whatever activation process is imposed on Taproot. Other developers have expressed similar opinions.
So what happened with SegWit activation that was so traumatic? SegWit used the BIP9 activation method. Let's dive into BIP9!

BIP9 Miner-Activated Soft Fork

Basically, BIP9 has a bunch of parameters:
Now there are other parameters (name, starttime) but they are not anywhere near as important as the above two.
A number that is not a parameter, is 95%. Basically, activation of a BIP9 softfork is considered as actually succeeding if at least 95% of blocks in the last 2 weeks had the specified bit in the nVersion set. If less than 95% had this bit set before the timeout, then the upgrade fails and never goes into the network. This is not a parameter: it is a constant defined by BIP9, and developers using BIP9 activation cannot change this.
So, first some simple questions and their answers:

The Great Battles of the SegWit Wars

SegWit not only fixed transaction malleability, it also created a practical softforkable blocksize increase that also rebalanced weights so that the cost of spending a UTXO is about the same as the cost of creating UTXOs (and spending UTXOs is "better" since it limits the size of the UTXO set that every fullnode has to maintain).
So SegWit was written, the activation was decided to be BIP9, and then.... miner signalling stalled at below 75%.
Thus were the Great SegWit Wars started.

BIP9 Feature Hostage

If you are a miner with at least 5% global hashpower, you can hold a BIP9-activated softfork hostage.
You might even secretly want the softfork to actually push through. But you might want to extract concession from the users and the developers. Like removing the halvening. Or raising or even removing the block size caps (which helps larger miners more than smaller miners, making it easier to become a bigger fish that eats all the smaller fishes). Or whatever.
With BIP9, you can hold the softfork hostage. You just hold out and refuse to signal. You tell everyone you will signal, if and only if certain concessions are given to you.
This ability by miners to hold a feature hostage was enabled because of the miner-exit allowed by the timeout on BIP9. Prior to that, miners were considered little more than expendable security guards, paid for the risk they take to secure the network, but not special in the grand scheme of Bitcoin.

Covert ASICBoost

ASICBoost was a novel way of optimizing SHA256 mining, by taking advantage of the structure of the 80-byte header that is hashed in order to perform proof-of-work. The details of ASICBoost are out-of-scope here but you can read about it elsewhere
Here is a short summary of the two types of ASICBoost, relevant to the activation discussion.
Now, "overt" means "obvious", while "covert" means hidden. Overt ASICBoost is obvious because nVersion bits that are not currently in use for BIP9 activations are usually 0 by default, so setting those bits to 1 makes it obvious that you are doing something weird (namely, Overt ASICBoost). Covert ASICBoost is non-obvious because the order of transactions in a block are up to the miner anyway, so the miner rearranging the transactions in order to get lower power consumption is not going to be detected.
Unfortunately, while Overt ASICBoost was compatible with SegWit, Covert ASICBoost was not. This is because, pre-SegWit, only the block header Merkle tree committed to the transaction ordering. However, with SegWit, another Merkle tree exists, which commits to transaction ordering as well. Covert ASICBoost would require more computation to manipulate two Merkle trees, obviating the power benefits of Covert ASICBoost anyway.
Now, miners want to use ASICBoost (indeed, about 60->70% of current miners probably use the Overt ASICBoost nowadays; if you have a Bitcoin fullnode running you will see the logs with lots of "60 of last 100 blocks had unexpected versions" which is exactly what you would see with the nVersion manipulation that Overt ASICBoost does). But remember: ASICBoost was, at around the time, a novel improvement. Not all miners had ASICBoost hardware. Those who did, did not want it known that they had ASICBoost hardware, and wanted to do Covert ASICBoost!
But Covert ASICBoost is incompatible with SegWit, because SegWit actually has two Merkle trees of transaction data, and Covert ASICBoost works by fudging around with transaction ordering in a block, and recomputing two Merkle Trees is more expensive than recomputing just one (and loses the ASICBoost advantage).
Of course, those miners that wanted Covert ASICBoost did not want to openly admit that they had ASICBoost hardware, they wanted to keep their advantage secret because miners are strongly competitive in a very tight market. And doing ASICBoost Covertly was just the ticket, but they could not work post-SegWit.
Fortunately, due to the BIP9 activation process, they could hold SegWit hostage while covertly taking advantage of Covert ASICBoost!

UASF: BIP148 and BIP8

When the incompatibility between Covert ASICBoost and SegWit was realized, still, activation of SegWit stalled, and miners were still not openly claiming that ASICBoost was related to non-activation of SegWit.
Eventually, a new proposal was created: BIP148. With this rule, 3 months before the end of the SegWit timeout, nodes would reject blocks that did not signal SegWit. Thus, 3 months before SegWit timeout, BIP148 would force activation of SegWit.
This proposal was not accepted by Bitcoin Core, due to the shortening of the timeout (it effectively times out 3 months before the initial SegWit timeout). Instead, a fork of Bitcoin Core was created which added the patch to comply with BIP148. This was claimed as a User Activated Soft Fork, UASF, since users could freely download the alternate fork rather than sticking with the developers of Bitcoin Core.
Now, BIP148 effectively is just a BIP9 activation, except at its (earlier) timeout, the new rules would be activated anyway (instead of the BIP9-mandated behavior that the upgrade is cancelled at the end of the timeout).
BIP148 was actually inspired by the BIP8 proposal (the link here is a historical version; BIP8 has been updated recently, precisely in preparation for Taproot activation). BIP8 is basically BIP9, but at the end of timeout, the softfork is activated anyway rather than cancelled.
This removed the ability of miners to hold the softfork hostage. At best, they can delay the activation, but not stop it entirely by holding out as in BIP9.
Of course, this implies risk that not all miners have upgraded before activation, leading to possible losses for SPV users, as well as again re-pressuring miners to signal activation, possibly without the miners actually upgrading their software to properly impose the new softfork rules.

BIP91, SegWit2X, and The Aftermath

BIP148 inspired countermeasures, possibly from the Covert ASiCBoost miners, possibly from concerned users who wanted to offer concessions to miners. To this day, the common name for BIP148 - UASF - remains an emotionally-charged rallying cry for parts of the Bitcoin community.
One of these was SegWit2X. This was brokered in a deal between some Bitcoin personalities at a conference in New York, and thus part of the so-called "New York Agreement" or NYA, another emotionally-charged acronym.
The text of the NYA was basically:
  1. Set up a new activation threshold at 80% signalled at bit 4 (vs bit 1 for SegWit).
    • When this 80% signalling was reached, miners would require that bit 1 for SegWit be signalled to achive the 95% activation needed for SegWit.
  2. If the bit 4 signalling reached 80%, increase the block weight limit from the SegWit 4000000 to the SegWit2X 8000000, 6 months after bit 1 activation.
The first item above was coded in BIP91.
Unfortunately, if you read the BIP91, independently of NYA, you might come to the conclusion that BIP91 was only about lowering the threshold to 80%. In particular, BIP91 never mentions anything about the second point above, it never mentions that bit 4 80% threshold would also signal for a later hardfork increase in weight limit.
Because of this, even though there are claims that NYA (SegWit2X) reached 80% dominance, a close reading of BIP91 shows that the 80% dominance was only for SegWit activation, without necessarily a later 2x capacity hardfork (SegWit2X).
This ambiguity of bit 4 (NYA says it includes a 2x capacity hardfork, BIP91 says it does not) has continued to be a thorn in blocksize debates later. Economically speaking, Bitcoin futures between SegWit and SegWit2X showed strong economic dominance in favor of SegWit (SegWit2X futures were traded at a fraction in value of SegWit futures: I personally made a tidy but small amount of money betting against SegWit2X in the futures market), so suggesting that NYA achieved 80% dominance even in mining is laughable, but the NYA text that ties bit 4 to SegWit2X still exists.
Historically, BIP91 triggered which caused SegWit to activate before the BIP148 shorter timeout. BIP148 proponents continue to hold this day that it was the BIP148 shorter timeout and no-compromises-activate-on-August-1 that made miners flock to BIP91 as a face-saving tactic that actually removed the second clause of NYA. NYA supporters keep pointing to the bit 4 text in the NYA and the historical activation of BIP91 as a failed promise by Bitcoin developers.

Taproot Activation Proposals

There are two primary proposals I can see for Taproot activation:
  1. BIP8.
  2. Modern Softfork Activation.
We have discussed BIP8: roughly, it has bit and timeout, if 95% of miners signal bit it activates, at the end of timeout it activates. (EDIT: BIP8 has had recent updates: at the end of timeout it can now activate or fail. For the most part, in the below text "BIP8", means BIP8-and-activate-at-timeout, and "BIP9" means BIP8-and-fail-at-timeout)
So let's take a look at Modern Softfork Activation!

Modern Softfork Activation

This is a more complex activation method, composed of BIP9 and BIP8 as supcomponents.
  1. First have a 12-month BIP9 (fail at timeout).
  2. If the above fails to activate, have a 6-month discussion period during which users and developers and miners discuss whether to continue to step 3.
  3. Have a 24-month BIP8 (activate at timeout).
The total above is 42 months, if you are counting: 3.5 years worst-case activation.
The logic here is that if there are no problems, BIP9 will work just fine anyway. And if there are problems, the 6-month period should weed it out. Finally, miners cannot hold the feature hostage since the 24-month BIP8 period will exist anyway.

PSA: Being Resilient to Upgrades

Software is very birttle.
Anyone who has been using software for a long time has experienced something like this:
  1. You hear a new version of your favorite software has a nice new feature.
  2. Excited, you install the new version.
  3. You find that the new version has subtle incompatibilities with your current workflow.
  4. You are sad and downgrade to the older version.
  5. You find out that the new version has changed your files in incompatible ways that the old version cannot work with anymore.
  6. You tearfully reinstall the newer version and figure out how to get your lost productivity now that you have to adapt to a new workflow
If you are a technically-competent user, you might codify your workflow into a bunch of programs. And then you upgrade one of the external pieces of software you are using, and find that it has a subtle incompatibility with your current workflow which is based on a bunch of simple programs you wrote yourself. And if those simple programs are used as the basis of some important production system, you hve just screwed up because you upgraded software on an important production system.
And well, one of the issues with new softfork activation is that if not enough people (users and miners) upgrade to the newest Bitcoin software, the security of the new softfork rules are at risk.
Upgrading software of any kind is always a risk, and the more software you build on top of the software-being-upgraded, the greater you risk your tower of software collapsing while you change its foundations.
So if you have some complex Bitcoin-manipulating system with Bitcoin somewhere at the foundations, consider running two Bitcoin nodes:
  1. One is a "stable-version" Bitcoin node. Once it has synced, set it up to connect=x.x.x.x to the second node below (so that your ISP bandwidth is only spent on the second node). Use this node to run all your software: it's a stable version that you don't change for long periods of time. Enable txiindex, disable pruning, whatever your software needs.
  2. The other is an "always-up-to-date" Bitcoin Node. Keep its stoarge down with pruning (initially sync it off the "stable-version" node). You can't use blocksonly if your "stable-version" node needs to send transactions, but otherwise this "always-up-to-date" Bitcoin node can be kept as a low-resource node, so you can run both nodes in the same machine.
When a new Bitcoin version comes up, you just upgrade the "always-up-to-date" Bitcoin node. This protects you if a future softfork activates, you will only receive valid Bitcoin blocks and transactions. Since this node has nothing running on top of it, it is just a special peer of the "stable-version" node, any software incompatibilities with your system software do not exist.
Your "stable-version" Bitcoin node remains the same version until you are ready to actually upgrade this node and are prepared to rewrite most of the software you have running on top of it due to version compatibility problems.
When upgrading the "always-up-to-date", you can bring it down safely and then start it later. Your "stable-version" wil keep running, disconnected from the network, but otherwise still available for whatever queries. You do need some system to stop the "always-up-to-date" node if for any reason the "stable-version" goes down (otherwisee if the "always-up-to-date" advances its pruning window past what your "stable-version" has, the "stable-version" cannot sync afterwards), but if you are technically competent enough that you need to do this, you are technically competent enough to write such a trivial monitor program (EDIT: gmax notes you can adjust the pruning window by RPC commands to help with this as well).
This recommendation is from gmaxwell on IRC, by the way.

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?

How long does it take for my balance to unlock?

Your balance is unlocked after 10 confirmations (which means 10 mined blocks). A block is mined approximately every two minutes on the Monero network, so that would be around 20 minutes.

How can I prove that I sent a payment?

The fastest and most direct way is by using the ExploreMonero blockchain explorer. You will need to recover the transaction key from your wallet (complete guide for GUI / CLI).

How do I buy Monero (XMR) with Bitcoin (BTC)?

There are dozens of exchanges that trade Monero against Bitcoin and other cryptocurrencies. Check out the list on CoinMarketCap and choose the option that suits you best.

How do I buy Monero (XMR) with fiat?

How can I quickly exchange my Monero (XMR) for Bitcoin (BTC)?

There are multiple ways to exchange your Monero for Bitcoin, but first of all, I'd like to remind you that if you really want to do your part for Monero, one of the simplest ways is to get in touch with your merchant/service provider and request for it to accept Monero directly as payment. Ask the service provider to visit the official website and our communication channels if he or she needs help with system integration.
That being said, the community has been recommending two services in particular, XMR.TO and MorphToken. These services are only recommendations and are operated by entities outside the control of the Monero Project. Be diligent.

How do I mine Monero? And other mining questions.

The correct place to ask questions and discuss the Monero mining scene is in the dedicated subreddit MoneroMining. That being said, you can find a list of pools and available mining software in the GetMonero.org website.

2. Wallet: CLI & GUI

Why I can't see my balance? Where is my XMR?

Before any action there are two things to check:
  1. Are you using the latest available version of the wallet? A new version is released roughly every 6 months, so make sure you're using the current release (compare the release on GetMonero.org with your wallet's version on Settings, under Debug info).
  2. Is your wallet fully synchronized? If it isn't, wait the sync to complete.
Because Monero is different from Bitcoin, wallet synchronization is not instant. The software needs to synchronize the blockchain and use your private keys to identify your transactions. Check in the lower left corner (GUI) if the wallet is synchronized.
You can't send transactions and your balance might be wrong or unavailable if the wallet is not synced with the network. So please wait.
If this is not a sufficient answer for your case and you're looking for more information, please see this answer on StackExchange.

How do I upgrade my wallet to the newest version?

This question is beautifully answered on StackExchange.

Why does it take so long to sync the wallet [for the first time]?

You have decided to use Monero's wallet and run a local node. Congratulations! You have chosen the safest and most secure option for your privacy, but unfortunately this has an initial cost. The first reason for the slowness is that you will need to download the entire blockchain, which is considerably heavy (+70 GB) and constantly growing. There are technologies being implemented in Monero to slow this growth, however it is inevitable to make this initial download to run a full node. Consider syncing to a device that has an SSD instead of an HDD, as this greatly impacts the speed of synchronization.
Now that the blockchain is on your computer, the next time you run the wallet you only need to download new blocks, which should take seconds or minutes (depending on how often you use the wallet).

I don't want to download the blockchain, how can I skip that?

The way to skip downloading the blockchain is connecting your wallet to a public remote node. You can follow this guide on how to set it up. You can find a list of public remote nodes on MoneroWorld.
Be advised that when using a public remote node you lose some of your privacy. A public remote node is able to identify your IP and opens up a range for certain attacks that further diminish your privacy. A remote node can't see your balance and it can't spend your XMR.

How do I restore my wallet from the mnemonic seed or from the keys?

To restore your wallet with the 25 word mnemonic seed, please see this guide.
To restore your wallet with your keys, please see this guide.

3. Wallet: Ledger

How do I generate a Ledger Monero Wallet with the GUI or CLI?

This question is beautifully answered on StackExchange. Check this page for the GUI instructions, and this page for the CLI instructions.

4. Nodes

How can my local node become a public remote node?

If you want to support other Monero users by making your node public, you can follow the instructions on MoneroWorld, under the section "How To Include Your Node On Moneroworld".

How can I connect my node via Tor?
