1.5C Here We Come

Source

John Timmer's With four more years like 2023, carbon emissions will blow past 1.5° limit is based on the United Nations' Environmental Programme's report Emissions Gap Report 2024. The "emissions gap" is:

the difference between where we're heading and where we'd need to be to achieve the goals set out in the Paris Agreement. It makes for some pretty grim reading. Given last year's greenhouse gas emissions, we can afford fewer than four similar years before we would exceed the total emissions compatible with limiting the planet's warming to 1.5° C above pre-industrial conditions.
...
The report ascribes this situation to two distinct emissions gaps: between the goals of the Paris Agreement and what countries have pledged to do and between their pledges and the policies they've actually put in place.

Back in 2021 in my TTI/Vanguard talk I examined one of these gaps, the one between the crypto-bros' energy consumption:

The leading source for estimating Bitcoin's electricity consumption is the Cambridge Bitcoin Energy Consumption Index, whose current central estimate is 117TWh/year.

Adjusting Christian Stoll et al's 2018 estimate of Bitcoin's carbon footprint to the current CBECI estimate gives a range of about 50.4 to 125.7 MtCO2/yr for Bitcoin's opex emissions, or between Portugal and Myanmar.

and their rhetoric:

Cryptocurrencies assume that society is committed to this waste of energy and hardware forever. Their response is frantic greenwashing, such as claiming that because Bitcoin mining allows an obsolete, uncompetitive coal-burning plant near St. Louis to continue burning coal it is somehow good for the environment.

But, they argue, mining can use renewable energy. First, at present it doesn't. For example, Luxxfolio implemented their commitment to 100% renewable energy by buying 15 megawatts of coal-fired power from the Navajo Nation!.

Second, even if it were true that cryptocurrencies ran on renewable power, the idea that it is OK for speculation to waste vast amounts of renewable power assumes that doing so doesn't compete with more socially valuable uses for renewables, or indeed for power in general.

Note that the current CBECI estimate shows that Bitcoin's energy consumption has increased 43% since 2021, a 12.7%/yr increase.

Follow me below the fold for more details of the frantic greenwashing, not just from the crypto-bros but from the giants of the tech industry that aims to ensure that:

Following existing policies out to the turn of the century would leave us facing over 3° C of warming.

It Was Ten Years Ago Today

Ten years ago today I posted Economies of Scale in Peer-to-Peer Networks . My fundamental insight was:

• The income to a participant in a P2P network of this kind should be linear in their contribution of resources to the network.
• The costs a participant incurs by contributing resources to the network will be less than linear in their resource contribution, because of the economies of scale.
• Thus the proportional profit margin a participant obtains will increase with increasing resource contribution.
• Thus the effects described in Brian Arthur's Increasing Returns and Path Dependence in the Economy will apply, and the network will be dominated by a few, perhaps just one, large participant.

In the name of blatant self-promotion, below the fold I look at how this insight has held up since.

It is generally quite difficult to upset the denizens of a wretched hive of scum and villainy by further besmirching their reputation, but recently the Trump family has succeeded.

Below the fold I explain how they did it, and why the denizens of the wretched hive are not happy.

Astroturfing

I seem to be stuck on the theme of cryptocurrency gaslighting with two weeks ago More Cryptocurrency Gaslighting and one week ago Greenwashing. Now I look at cryptocurrency gaslighting in the political arena, where it is termed astroturfing:

it is defined as the process of seeking electoral victory or legislative relief for grievances by helping political actors find and mobilize a sympathetic public, and is designed to create the image of public consensus where there is none. Astroturfing is the use of fake grassroots efforts that primarily focus on influencing public opinion and typically are funded by corporations and political entities to form opinions.

Donald Trump, 2019

Currently, the crypto-bros have poured money into primaries, defeated several incumbents deemed to be insufficiently crypto-friendly, and have accumulated an immense war-chest for November's general election. This pot of gold was enough to turn Trump from crypto-skeptic to telling Maria Bartiromo:

Who knows, maybe we’ll pay off our $35 trillion dollar [national debt], hand them a little crypto check, right? We’ll hand them a little Bitcoin and wipe away our $35 trillion

Below the fold I discuss the gaslighting the cryptosphere is using in their massive attempt to purchase "regulatory clarity", and what the scale of this investment suggests about the profits they expect to garner if it succeeds.

You have only to scan Molly White's Web3 is Going Just Great to realize that you will never find a more wretched hive of scum and villainy than the cryptosphere. Everywhere you look you find lies, grift, fraud, and theft. Below the fold I discuss the latest example, in which a coal company marketing itself as "zero-carbon Bitcoin mining" is just the start.

More Cryptocurrency Gaslighting

SEC vs. Consensys

On 30^th June Amy Castor and David Gerard reported that SEC sues Consensys over MetaMask Swaps and Staking:

The SEC is charging Consensys for unauthorized sales of securities through MetaMask Staking and for failure to register as a broker and a dealer while offering crypto trades and staking services through MetaMask Staking and Swaps. The SEC says that Consensys took $250 million in fees as an unregistered broker.

MetaMask is Consensys’ main money maker — a popular browser-based wallet that also lets you stake ETH and buy and sell crypto via decentralized exchanges with “swaps.”

Consensys' defense strategy poses potentially serious problems for the concept of open source, because they are gaslighting about the software that is the basis for the SEC's complaint being open source. Were the court to (a) fall for their gaslighting but (b) agree with the SEC's complaint it could provide a basis for imposing liability on open source developers.

I am afraid that the explanation for why this is so is necessarily rather long but I and others think that it needs to be understood. So stock up with supplies for the journey and follow me below the fold.

Matt Levine Explains Cryptocurrency Markets

Kanav Kariya

Matt Levine's superpower is his ability to describe financial issues in wonderfully simple terms, and in a section of Monday's column entitled Crypto is for fun he is on top form:

In many cases, the essential attribute of a crypto token is liquidity: What you want, often, is a token that trades a lot, because your goal for the token is to trade it a lot. Real-world utility, a sensible business model, acceptance in real transactions, etc., are all less important than just trading if you think of crypto as a toy market for traders to play with. If a token trades a lot at a high price, that in itself justifies the price, because that is all that is asked of a token: It doesn’t need to have a good underlying business or cash flows; it just has to trade a lot at a high price.

Below the fold I discuss the astonishing story behind this explanation of why wash trading is so rife in cryptocurrencies.

More On The Halvening

At the end of May I wrote One Heck Of A Halvening about the aftermath of the halving of Bitcoin's block reward on April 19^th. Six weeks later it is time for a quick update, so follow me below the fold.

The Great MEV Heist

The Department of Justice indicted two brothers for exploiting mechanisms supporting Ethereum's "Maximal Extractable Value" (MEV). Ashley Berlanger's MIT students stole $25M in seconds by exploiting ETH blockchain bug, DOJ says explains:

Anton, 24, and James Peraire-Bueno, 28, were arrested Tuesday, charged with conspiracy to commit wire fraud, wire fraud, and conspiracy to commit money laundering. Each brother faces "a maximum penalty of 20 years in prison for each count," the DOJ said.

The alleged scheme was launched in December 2022 by the brothers, who studied at MIT, after months of planning, the indictment said. The pair seemingly relied on their "specialized skills" and expertise in crypto trading to fraudulently gain access to "pending private transactions" on the blockchain, then "used that access to alter certain transactions and obtain their victims’ cryptocurrency," the DOJ said

Below the fold I look into the details of the exploit as alleged in the indictment, and what it suggests about the evolution of Ethereum.

One Heck Of A Halvening

The fundamental idea behind Bitcoin is that, if you restrict the supply of something, its price will rise. That is why the system arranges that there will only ever be 21 million Bitcoin by halving the reward paid for mining the next block every 210,000 blocks (about every four years), an event called the "halvening" (or more recently just the halving). It is an article of faith among the crypto-bros that, after the halvening, the price will rise. For example:

In the image below, the vertical blue lines indicate the previous three halvings (2012-11-28, 2016-7-9, and 2020-5-11). Note how the price has jumped significantly after each halving.

The most recent halvening happened on Friday, April 19^th. It was eagerly awaited so, six weeks later, it is time to go below the fold and look at the effects.

"Sufficiently Decentralized"

Mining Pools 5/17/24

In June 2018 William Hinman, the Director of the SEC's Division of Corporate Finance, gave a speech to the Yahoo Finance All Markets Summit: Crypto entitled Digital Asset Transactions: When Howey Met Gary (Plastic) in which he said:

when I look at Bitcoin today, I do not see a central third party whose efforts are a key determining factor in the enterprise. The network on which Bitcoin functions is operational and appears to have been decentralized for some time, perhaps from inception.
...
Over time, there may be other sufficiently decentralized networks and systems

Below the fold, thanks to a tip from Molly White, I look at recent research suggesting that there is in fact a "central third party" coordinating the enterprise of Bitcoin mining.

Fee-Only Bitcoin

Mining a Bitcoin block needs to be costly to ensure that the gains from an attack on the blockchain are less than the cost of mounting it. Miners have two sources of income to defray their costs, the block rewards and the fees for the transactions in the block.

On April 19^th the block reward was halved from 6.25BTC to 3.125BTC. This process is repeated every 210,000 blocks (about every 4 years). It limits the issuance of BTC to 21M because around 2140 the reward will be zero; a halving will make it less than a satoshi.

Long before 2140 the block rewards will have shrunk to become insignificant compared to the fees. Below the fold I look at the significance of the change to a fee-only Bitcoin

The Left Curve

@tzedonn

Muyao Shen explains the concept of the Left Curve in The Big Winners of This Crypto Bull Market Are the `Left Curves’:

There is a surprising amount of respect for people who appear to know nothing about the industry. They’re known as the “left curves.”

The nickname comes from a popular meme in crypto that shows a bell curve with investors on the left who know nothing, or very little, and those in the fat middle of the curve who know something about crypto. On the right are investors who seemingly know everything.

Below the fold I look at the left side of the curve

More On Pig Butchering

Thankfully, pig butchering scams are getting attention. Three weeks after I posted Tracing The Pig Butchers, John M. Griffin and Kevin Mei posted How Do Crypto Flows Finance Slavery? The Economics of Pig Butchering:

Through blockchain addresses used by ‘‘pig butchering’’ victims, we trace crypto flows and uncover methods commonly used by scammers to obfuscate their activities, including multiple transactions, swapping between cryptocurrencies through DeFi smart contracts, and bridging across blockchains. The perpetrators interact freely with major crypto exchanges, sending over 104,000 small potential inducement payments to build trust with victims. Funds exit the crypto network in large quantities, mostly in Tether, through less transparent but large exchanges—Binance, Huobi, and OKX. These criminal enterprises pay approximately 87 basis points in transaction fees and appear to have recently moved at least $75.3 billion into suspicious exchange deposit accounts, including $15.2 billion from exchanges commonly used by U.S. investors. Our findings highlight how the ‘‘reputable’’ crypto industry provides the common gateways and exit points for massive amounts of criminal capital flows. We hope these findings will help shed light on and ultimately stop these heinous crimes.

Griffin & Wei Fig. 9

Their Figure 9 shows the flow of funds over time into the scammer's wallets at exchanges. This is how they estimated the $75.3B; their extremely conservative estimate is $35.1B, and their liberal estimate is $237.6B. Note the huge ~$45B increase from January 2021 to January 2023, partly driven by the cryptocurrency boom, and the slowing until January 2024. Presumably the ETF pump will accelerate the rate.

Below the fold, some commentary on this and other recent developments.

Clouds Over The Mines

In early December 2022 when I wrote skeptically about the economics of Bitcoin mining in Foolish Lenders the Bitcoin "price" was around $17K. It has now climbed 153% to around $43K and, below the fold, I am still posting skeptically about the economics of mining.

Tracing The Pig Butchers

"Vicky"

Chapter 18 of Zeke Faux's Number Go Up: Inside Crypto's Wild Rise and Staggering Fall is entitled "Pig Butchering". It starts when he receives a supposed wrong-number text from a "Vicky":

I showed my phone to my friend and explained that I was stringing Vicky along because I’d heard about a new kind of investment fraud that often started with a random text message. I had a hunch that this was why “Vicky” was texting me. The scam was called “pig butchering” because the scammers liked to build up the victim’s confidence with a pretend romantic relationship and made-up investment gains before stealing all their money in one fell swoop—like how hogs are fattened up before their slaughter.

This is a romance- and cryptocurrency-enabled version of the "Wee Forest Folk" scam we described in our 2003 SOSP paper.

Below the fold, I look into the details of pig-butchering scams, and how the tracing techniques I discussed in Criming On The Blockchain are being applied to identify the cryptocurrency companies facilitating it.

Criming On The Blockchain

I apologize for the delay in posting but, as you will see, the post I was working on grew rather long.

It seems obvious that doing crimes and writing the receipts to an immutable public ledger is risky, but many criminals have been convinced that there is no risk because cryptocurrencies such as Bitcoin are anonymous. Although there are cryptocurrencies with anonymous transactions, such as Monero and zCash, they are much more difficult to use and much less liquid than pseudonymous cryptocurrencies like Bitcoin. As many criminals have discovered, without an unrealistically intense focus on operational security (opsec), the identity behind the pseudonym can be revealed. An entire industry has evolved to do these revelations, tracing the flow of coins through their blockchains.

Below the fold I discuss the techniques and results of blockchain tracing, based on four main sources:

• Andy Greenberg's new book entitled Tracers in the Dark: The Global Hunt for the Crime Lords of Cryptocurrency.
• Chainalysis' report 2024 Crypto Crime Trends: Illicit Activity Down as Scamming and Stolen Funds Fall, But Ransomware and Darknet Markets See Growth and his ‘Stablecoins’ Enabled $40 Billion in Crypto Crime Since 2022.
• The UN Office for Drugs and Crime (UNODC) report Casinos, Money Laundering, Underground Banking, and Transnational Organized Crime in East and Southeast Asia: A Hidden, Accelerating Threat.

Good News For Tether

USDT "market cap"

The good news for Tether is shown in this graph, with two huge surges in "market cap" this year. One of about $15B early in the year, and another of about $6B recently. It looks like the euphoria over the prospect of spot Bitcoin ETFs has solved the Greater Fool Supply-Chain Crisis with the cryptosphere experiencing a massive inflow of around $20B actual dollars. As one might expect from injecting $20B whose only uses are to HODL or to buy cryptocurrency into the market, the result has been a massive bubble in cryptocurrency "prices".

BTC "price"

Bitcoin has gone from about $16K at the start of the year to around $42K recently. Ethereum has merely doubled, from about $1.2K to about $2.4K.

So all is well with the world; Tether gets to keep the interest on another $20B, which at say 4% is an extra $800M/year on their bottom line, and the Bitcoin HODL-ers see their investment gamble return a 160% gain. Is all really well with the world? Follow me below the fold.
