Capping days of mounting anticipation, a documentary aired Tuesday said Canadian software developer Peter Todd is Satoshi Nakamoto, the pseudonymous cypherpunk who created Bitcoin.
But the evidence filmmaker Cullen Hoback marshalled in âMoney Electric: The Bitcoin Mysteryâ is unlikely to satisfy everyone who has long analysed the clues left by Nakamoto, who mysteriously vanished in 2011, three years after sharing the Bitcoin white paper on the P2P Foundation website.
Todd himself has denied Cullenâs claim in the documentary, calling it âludicrous,â and on X Tuesday evening.
Journalists and crypto sleuths have spent years trying to solve what may be the greatest mystery in modern finance: Who is Satoshi Nakamoto?
Usual suspects
Their efforts have turned up several names, and some have suggested Nakamoto was a group of people. The usual suspects â Nick Szabo and Adam Back, among them â have denied they are Satoshi.
One 2014 report said Satoshi Nakamoto was none other than a man by the same name living quietly, and openly, in Southern California. Speculation has also turned to X owner and multibillionaire Elon Musk.
Craig Wright, an Australian computer scientist tried â and failed â to prove he was Nakamoto in a lawsuit filed in the UK.
The question of Nakamotoâs identity is more than idle speculation.
Bitcoin, introduced 15 years ago, is the original cryptocurrency and the anchor of the crypto economy, now worth $2.3 trillion.
Central banks are studying blockchain technology, Wall Street giants are offering Bitcoin funds, and the two candidates for US president in the November 5 election have referenced crypto on the campaign trail.
$67 billion stash
Nakamoto is estimated to control 1.1 million Bitcoins, worth about $67 billion at Tuesdayâs prices.
If Nakamoto has access to that mass of Bitcoins, it would mean the creator could one day attempt to sell them, an event that would likely have a dramatic impact on the tokenâs price.
Ahead of its initial public offering in 2021, for instance, Coinbase said the identification of Nakamoto or the transfer of their Bitcoins was a factor that would adversely affect its business.
The cryptographers club
Nakamoto spoke openly and often in a whoâs who email group of mathematicians and cryptographers referred to as the cypherpunk mailing list.
Members included Julian Assange, the founder of WikiLeaks; Ross Ulbricht, the founder of dark web marketplace Silk Road; and Vitalik Buterin, the co-founder of Ethereum.
Nakamotoâs communication on the mailing list abruptly stopped in December 2010. His last known email was sent in April 2011.
Ahead of the documentaryâs debut, bettors on Polymarketâs pool about Satoshiâs identity wagered $20 million on various candidates. Most bet Hoback would identify multiple creators, or someone not among the 15 named candidates.
Once the frontrunner among named Nakamoto candidates on Polymarket, late American cryptographer Len Sassaman fell out of bettorsâ favour Monday after Hoback told CNN he confronts Nakamoto in the documentary.
And Sassamanâs widow, Meredith Patterson, told DL News that HBO never approached her when making the documentary.
Bettors then turned their attention to American polymath and computer scientist Nick Szabo. Yet by late afternoon New York time his odds had also fallen. Suddenly Adam Back, the CEO of Blockstream, was the frontrunner among named candidates.
Szabo has repeatedly said he isnât Satoshi.
But he was a member of the cypherpunk mailing list, and is known to have worked on something he called Bit Gold before Nakamoto published the Bitcoin white paper.
13 candidates
In addition, a controversial 2014 study by the Aston University Centre for Forensic Linguistics analysed the writing style of 13 popular Nakamoto candidates and said Szaboâs was closest to that of the author of the Bitcoin white paper.
The Bitcoin white paper references Backâs Hashcash protocol and Wei Daiâs B-Money. Back and Dai are both members of the cypherpunk mailing list.
Another longtime candidate was the late software developer Hal Finney.
Finney was the first to reply to the Bitcoin white paper, the first person to download the software, and the second miner after Satoshi to verify transactions.
In 2009, Finney was diagnosed with ALS, an incurable motor neuron disease.
Some have speculated that Finneyâs declining health explains Satoshiâs disappearance from the web in 2011.
Finney denied he was Satoshi in an interview with Forbes shortly before his death in 2014.
Old wallets
Adding to the intrigue, over a dozen early Bitcoin wallets have sprung back to life over the past week.
In recent months, these wallets, among the first active on the network between 2009 and 2010, have moved a combined $35 million to new addresses and crypto exchanges.
Normally, such movements wouldnât draw significant attention. Itâs not uncommon for old wallets to move Bitcoin around occasionally.
But the increased frequency of wallet movements, coupled with the announcement of a documentary focusing on Nakamotoâs identity, added a fresh layer of intrigue.
