I read up to here, but I wasn't convinced that this is the revelation that the author claims. To my knowledge, asymmetric cryptography is widely used. I have no opinions on the rest of the article, though.

The rest of the arguments is as weak:
1) both released open-source software
2) both don't like spam
3) both like using pseudonyms online
4) both love freedom
5) both are anti-copyright
etc.
Basically, the author found that Adam Back used the same words on X as Satoshi did in some emails (including such rare words as "dang," "backup," and "abandonware") and then decided to find every possible "link" they could to build the case, even if most of the links are along the lines of "Both are humans! Coincidence? I think not."
It's weird they spent so much time on the written word similarities, when the biggest reveal here is that Back disappears off the email lists (on a topic he is VERY interested in and has historically corresponded on) when Nakamoto appears, and then comes back when Nakamoto disappears.
Only if those similarities are indicating more than 'generic internet hacker' for both of them. You only need 23 bits to identify a person but those are 23 uncorrelated bits, and all the 'similarities' presented here are extremely strongly correlated with themselves.
Yeah, but as Wordle fans know, some clues yield more bits than others. The search space is not balanced.
The search space of hackers is a small subtree of all humans. So it's like a smaller tree of groups in Wordle that contains the letter "H".
However, in reality there is no binary "hacker" bit, so maybe we're back to the brute force 33-bit space. And then, you don't know Satoshi's unique signature, and it's worse if Satoshi is a group.
Come to think of it, do all hacker news posters even share a hacker bit?
I still rely on information-theoretic proofs at work, they just don't involve messy humans.
Similarities in style and word were common enough in small circles such as the cyphyrpunks that spawned those discussions.
Then there's not altogether unlikely chance that Satoshi is a nodding homage to Nicolas Bourbaki, each contributor holding part of a multiparty voting key.
The interests and writing style differentiate Mr. (Dr.?) Back from the general public, sure. But from what I’m reading, they don’t do a great job of distinguishing between 90s hackers.
“Get this, his PhD thesis dealt with a computer language called C++, just like Bitcoin papers used” seems both confused and impossibly lazy to me.
> “Scrap patents and copyright,” Mr. Back wrote in September 1997.
> Satoshi did a similar thing. He released the Bitcoin software under M.I.T.’s open-source license
Really?
Like saying “get this, his college-aged musical interests included the Urban American musical style known as ‘Hip Hop’; therefore Tupac didn’t really die and this is him.” Heavy on insinuation, light on seriousness. Strong “…you’re not from around here, are you?” vibes.
What does this kind of journalism hope to accomplish, anyway? Beyond bothering middle-aged nerds for gossip? And providing a frame for the author’s cute little sleuth jape?
“Good reason to look closer” assumes there’s good reason to pick through ancient rubble in the first place.
All 12,000 words. Kept expecting it to take a turn toward something beyond pre-judgment and insinuation. Instead it unfolded as a cautionary tale, of the power of a premature conclusion to close an investigator’s mind to reasonable alternative possibilities. About escalating commitment to an early hunch, even as it leads you down an investigative dead end.
For example it sure seems like his mountain of circumstantial evidence fits better with the theory that “Satoshi” could be a pen name for a small group of people—maybe even the small group whose history he traces and whose styles he has trouble teasing apart—rather than one “suspect” (as he calls it). But we don’t even really weigh that possibility seriously.
So, like—why are we coming at this one guy by name and spooky hacker photo in the New York Times, with the suggestion that he has $110 billion under his mattress? All these speculations and arguments have been done over and over—what does this reporting add that’s worth 12,000 words?
The colorful journey down a dead end, fine—but leave it at “My Quest,” don’t do the weasel subhed “the trail of clues […] led to Adam Back” to insinuate that it proved what it set out to prove. Or even added anything significant to the well-trodden record.

Does it? I didn't come to that conclusion. Do share!

Well, they identified this guy and the reporting here is better than the others I've seen in the past. This article obviously has nothing to do with what past writers wrote, so I don't really get the point of pretending like it all comes from one place.

I remember having conversations with my brother about Hashcash at the time. There were plenty of nerds that followed that mailing list that had similar technical and political ideas, so I think you'd find a high number of coincidences within an audience that I'd guess was a small multiple of the number of people active on the cypherpunks list. There definitely were a lot of people at my brother's college discussing the same ideas.
FWIW my brother did his own bit of Satoshi hunting with coworkers at his hedge fund. They didn't come to a strong answer but my brother believed Nick Szabo was probably part of a group that helped edit the paper. He suspected Hal Finney was involved similarly at a minimum.
It's been extremely widely known that whoever created Bitcoin had a strong interest in Hashcash, and perhaps created that or worked on it, for years and years. If that's the only smoking gun, why didn't we identify Satoshi long ago?
You're right, "interested in Hashcash" describes dozens of people, and has been a known Satoshi filter for years.
The new claim is more specific: between 1997-1999, Back proposed combining Hashcash with b-money, adding inflation adjustment via increasing computational difficulty, and using hash trees for public timestamping.
That's most of Bitcoin's architecture in one package, a decade early.
The number of people who proposed that particular combination of ideas is much smaller than the number who were merely interested in Hashcash.
I agree with the parts worth engaging with. I hate when people weak-man arguments.
But interesting as this is, there are others who fit at least as well. That bit gold was the closest proposed scheme to Bitcoin is well known, and we know the proposer of bit gold (Szabo) was actively soliciting partners to help implement it as a real system right before Bitcoin appeared.
Also, people leave mailing lists and come back randomly months later all the time. Adam could have simply been unlucky, and busy with other projects at the time of the launch. Lots of people were, and kicked themselves for it (which honestly, it seems Adam did too!).
Adam Back is credited in the Bitcoin whitepaper as the inventor of Hashcash. W. Dai is credited as the inventor of b-money. But Nick Szabo is not credited as the inventor of bit gold, by far the most mature of these ideas floating around at the cipherpunks mailing list at the time. That's a conspicuous absence.
You need someone who read Back's obscure 1997-1999 cypherpunks posts about combining Hashcash and b-money, implemented exactly that system a decade later, independently came up with the same non-technical analogies and trivia, wrote with the same hyphenation errors, and then happened to be active during the exact window Back went silent. The more you flesh out the "someone who read Back" profile, the more it just sounds like Back.
Someone who has read his material would be likely to repeat the same analogies and trivia.
As for the hyphen errors, they are common for people for whom English is their second language. I commit hyphen errors similar to what is described all the time because English hyphenation makes absolutely no sense. In fact, reading the list of examples, the mistakes listed makes more sense to me than the correct way of writing those.
I also switch back and forth on a lot of the phrases the article mentions.
I also switch back and forth between US and UK spelling, because I learned UK spelling at school, but was far more exposed to US spelling in practice.
At some point "Satoshi was a devoted reader of obscure 1997 Adam Back mailing list posts who shares his hyphenation errors, his Napster vs Gnutella analogy, his celebrity email filtering idea, his FDR gold ban interest, his 'burning the money' metaphor, his 'Achilles heel' description of DigiCash, his 'better with code than words' self-assessment, his energy-vs-banking defense, his British spellings mixed with American ones, his double-spacing habit, his it's/its confusion, his sentence-final 'also' tic, his 'proof-of-work' hyphenation, his WebMoney references, and who went active the exact week Back went silent" is just a longer way of saying it's Adam Back.
I'm not sure I agree with that, but it's what I came up with after challenging myself to read the article in toto again and note 1 by 1.
It's clear it's beyond a couple tics everyone has, and when you combine that with the starting set being ~500 instead of "all 8 billion people on earth", well, it's worth mentioning.
Your entire first paragraph boils down to me as someone who admired Adam Back and who may or may not have English as a second language, coupled with the one additional coincidence of when he was around.
In terms of language, I don't agree it's beyond a couple of tics everyone has at all. I also don't agree with the assumption that the starting set is ~500.
It's of course possible that it is Adam Back, but I don't find the purported evidence remotely compelling as a way of showing that it is.
Yeah, I'm Norwegian, and maybe the Scandinavian languages makes us extra likely to make those mistakes, but overall English hyphen rules to a large extent boils down to feels. Words "graduate" to hyphens over time as and when they start to become seen as a unit, and then sometimes eventually fuse into words. E-mail to email is one of those. And that pipeline is also not uniform geographically so different English speakers will disagree about what should have hyphens where and when...
This article is a great example of "strong + weak = weak".
I only made it to the interesting stuff because of Carreyou's name, otherwise I would have stopped.
The email timing and lack of email metadata were also strong, in my opinion. But all of this nonsense like "Wow, these guys both talk about PGP??" distracts from it.
I don't blame you for this initial reaction, which would have been mine too had I not known who the author was. I don't mean that I automatically trust anything published by the reporter who busted Theranos (and won two Pulitzers for other major investigations). But I do mean that if John Carreyrou and his editors decided to publish something this long, that means they (and they're lawyers) are willing to die on this hill, no matter how meandering the first paragraphs of his 1st-person narrative.
Since the story doesn't end with: "And then Adam Back bowed his head and said, 'You have found me, Satoshi'", I'm guessing they preferred to go for the softer "how we did this story" first-person narrative. There is no explicit smoking gun, like an official document or eyewitness who asserts Satoshi's identity. But the circumstantial and technical evidence is quite thorough, to the point where the most likeliest conclusions are:
1. Adam Back is Satoshi
2. Satoshi is someone who is either a close friend or frenemy of Back, and deliberately chose to leave a obfuscated trail that correlates with Back's persona and personal timeline.
If Mr Carreyrou is such a good writer then he should be embarrassed to publish trash:
> In keeping with this belief, Mr. Back made his Hashcash spam-throttling software open source.
> Satoshi did a similar thing. He released the Bitcoin software under M.I.T.’s open-source license, which allowed anyone to use, modify and distribute it without restrictions.
The numerous observations such as this only seem impressive to people who don't know anything at all about the subject. Occam's Razor suggests that the reason that such irrelevant observations were included is because Carreyrou doesn't know anything at all about the subject.
> When we compared those errors with the writings of our hundreds of suspects, Mr. Back was a clear outlier. He shared 67 of Satoshi’s exact hyphenation errors. The person with the second-most matches had 38.
You’re talking about “Occam’s razor” while noticing things in an article that may not be relevant while informing huge swathes of the article.
Occam’s razor suggests you’re doing this because you want the article to be wrong and want to pretend to be a genius, not because you actually think it is
I neither want the article to be wrong nor right. I don't care who Satoshi is.
The article is written as if it's by some crazed conspiracy theorist. It's dripping with confirmation bias at every turn. Tiny coincidences are seized upon to confirm the author's suspicions whereas other explanations are minimized.
This kind of one-track reasoning almost always turns out to be wrong. Did the author accidentally stumble upon the truth? It's possible. Back has all the right qualifications to be Satoshi. But so do many other people.
wrt (2) that is if satoshi had the foresight btc would ever blow up in the way it did. obviously, he had some intuition, remaining anonymous, but deliberately creating a fake trail does not seem super plausible to me
I got about two sentences further, it turns out another smoking gun is Mr. Back using c++ in his graduate studies, just like the original bitcoin implementation.
Yeah, based on the list of interests, I guess I've been Satoshi all this time and didn't know it. A shame my memory must have been wiped as I'd quite like all of those bitcoins.
> So does Bitcoin. A Bitcoin user has two keys: a public key, from which an address is derived that acts as a digital safe deposit box; and a private key, which is the secret combination used to unlock that box and spend the coins it contains.

I read up to here, but I wasn't convinced that this is the revelation that the author claims. To my knowledge, asymmetric cryptography is widely used. I have no opinions on the rest of the article, though.
