The identity of the pseudonymous Bitcoin creator has eluded sleuths for years. But does finding the real Mr. Nakamoto really matter?
There are two ambitious missions behind “Money Electric: The Bitcoin Mystery,” a new documentary by the filmmaker Cullen Hoback that was released Tuesday by HBO.
The first is to solve one of the internet’s great mysteries by revealing, at long last, the identity of Satoshi Nakamoto, the pseudonymous programmer who created Bitcoin in 2008.
The film’s second mission is to make the case that the identity of Bitcoin’s creator actually matters — that Bitcoin, for all its flaws, represents an important technological breakthrough with far-reaching implications, and that there are good reasons, aside from prurience, to care who created it.
Let’s start with the first part. Among Bitcoin buffs and cryptocurrency journalists, the mystery of Mr. Nakamoto’s identity has been the subject of fierce debate and painstaking investigation for more than a decade. But nothing has been proved conclusively, and a handful of bungled attempts to crack the case — most notoriously a 2014 Newsweek cover story that put the blame on a physicist, Dorian Nakamoto, who turned out to have nothing to do with Bitcoin at all — have only muddied the waters.
(My former colleague Nathaniel Popper suggested that Nick Szabo, who created a digital currency with similarities to Bitcoin, was most likely Satoshi Nakamoto back in 2015, but Mr. Szabo has denied it, and no conclusive evidence has emerged.)
Mr. Hoback, who spent years diving down the rabbit hole of the QAnon conspiracy theory for his last film, “Q: Into the Storm,” took a similarly exhaustive approach this time. He and a camera crew spent three years flying around the world interviewing early Bitcoin contributors, following digital breadcrumbs buried in ancient message board posts and piecing together the evidence.
They emerged with a theory that Mr. Nakamoto is Peter Todd, a Canadian programmer who contributed to Bitcoin during its early days.
“I’m very convinced,” Mr. Hoback told me in an interview this week. “Based on the evidence, I believe Peter Todd was Satoshi. He may have let others in on the secret, but everything lines up with him.”
Mr. Todd is not one of the usual suspects put forth by sleuths. (On Polymarket, a prediction market where Bitcoin fans were placing bets on whom the film would identify as Mr. Nakamoto ahead of Tuesday’s release, Mr. Todd’s name was nowhere on the list.) And some Bitcoin believers will scoff at the idea that Mr. Todd, a cryptography whiz who was just 23 when the Bitcoin white paper was released, would have been capable of conceiving such a sophisticated system.
But Mr. Hoback marshals plenty of evidence to support his theory. The most compelling clue is a 2010 exchange on a Bitcoin forum in which Mr. Todd responded to a post by Mr. Nakamoto in a way that seemed to be continuing the Bitcoin creator’s train of thought, perhaps indicating that they were the same person, and that he had mistakenly posted from the wrong account. Soon after, Mr. Todd’s account went dark, and Mr. Nakamoto disappeared.
The film also points to several other incongruities in Mr. Todd’s story: an old résumé of his that claimed proficiency in C++, the programming language used to write the original Bitcoin code base, which he would later deny knowing; a fake account he may have created to cover his tracks while establishing a new Bitcoin feature known as replace-by-fee; and some similarities in word choice and writing style between him and Mr. Nakamoto.
Then there’s Mr. Todd’s on-camera reaction when Mr. Hoback confronts him with his theory. He stammers; he scoffs; he calls the idea “ludicrous.” But he doesn’t exactly absolve himself, or name a more plausible suspect.
“We gave him every opportunity to explain why he made that post in 2010,” Mr. Hoback told me. “And not only does he not answer the question, he’s at a loss for words. Peter’s never at a loss for words.”
Compelling as it is, none of this amounts to a smoking gun. And filmmakers who devote years of their lives to solving a mystery, as Mr. Hoback did here, have a vested interest in coming to a tidy conclusion. To prove beyond a reasonable doubt that Mr. Todd is Mr. Nakamoto, you would have to catch him using the private keys to Mr. Nakamoto’s Bitcoin wallet, or dig up some incontrovertible forensic evidence connecting the two. That didn’t happen here.
But I found the evidence persuasive enough to run with the idea that Mr. Todd was, at a minimum, substantially involved in creating Bitcoin, at least until a better theory emerges.
On Tuesday, Mr. Todd sent me an email denying the film’s central claim.
“For the record, I am not Satoshi,” he wrote. (He added: “It’s a useless question, because Satoshi would simply deny it.”)
He said the 2010 message board post, which the film held up as evidence of his connection to Mr. Nakamoto, was “just a coincidence.”
“I’m not Satoshi, so that’s just me replying with a minor correction to one of Satoshi’s posts,” he wrote.
Now, to the second question raised by the film: Who cares who Mr. Nakamoto is?
Bitcoin’s successes and failures as a cryptocurrency thus far (and there have been plenty of both) haven’t hinged on the identity of its founder. Mr. Nakamoto stopped contributing to Bitcoin’s development in 2011, and hasn’t taken part in the most important discussions about the project’s future. Knowing who he is wouldn’t dissuade the legions of Bitcoin fans who think it’s the “one true currency,” or persuade crypto skeptics who think it’s all a scam.
Mr. Hoback made the case, both in the film and in our interview, that the reason to care about Mr. Nakamoto’s identity comes down to money and power.
According to many estimates, Mr. Nakamoto controls, or used to control, a digital trove of more than a million Bitcoin, roughly 5 percent of the total supply. At today’s prices, that stash would be worth more than $60 billion, making its owner one of the richest people in the world.
A vast majority of the coins in the so-called Satoshi wallets have never been touched. But they haven’t been destroyed, either. If Mr. Nakamoto still controls these wallets, and has a way to retrieve what’s inside, it could mean that there is a deca-billionaire hiding in plain sight, who could emerge at any time.
“Wouldn’t you want to know if there was an anonymous person out there who controlled one-twentieth of all the gold on the planet?” Mr. Hoback asked me.
I would, of course, but I would be even more curious to know what Mr. Nakamoto thinks of what has happened to Bitcoin in the 16 years since he (or she, or they) created it.
It’s easy to lose sight of how wild a ride it has been. In less than two decades, Bitcoin has given rise to a trillion-dollar cryptocurrency industry, enabled scams and illicit activity on a previously unimaginable scale, created and destroyed world-historic fortunes, been adopted as legal tender by several countries, sparked bitter regulatory fights around the world, become part of millions of Americans’ retirement funds and spawned a tribe of die-hard Bitcoin “maximalists” who believe the currency is going to replace the U.S. dollar.
It’s a great story, and I hope Mr. Nakamoto will step out of the shadows and tell it someday. Until then, we’re left to wonder, and to admire the work of those, like Mr. Hoback, who go digging for clues.
