LONDON, April 13, 2026, 15:17 BST
Another burst of reporting over the weekend and into Monday put British cryptographer Adam Back right back in the Satoshi Nakamoto spotlight. Still, the headlines lacked what matters: definitive proof. Back continues to reject claims tying him to Satoshi, following last week’s New York Times piece naming him the leading suspect so far.
That carries extra weight these days. Since U.S. regulators greenlit spot bitcoin ETFs in January 2024, bitcoin has dug in further with institutional investors. On Monday, the token hovered near $71,580; at that price, the roughly 1.1 million coins often linked to Satoshi would fetch about $78.7 billion.
The divide is obvious now. In just the last two days, Yahoo Finance pushed out both explainer and profile stories focused on Back. But on Monday, Tyler Cowen, writing for The Free Press, said the new case only gives “plausible hints—but no certainty.” Some investors and analysts, for their part, say the network’s scale means its founder’s identity doesn’t really matter anymore.

Back isn’t some peripheral figure. As Blockstream’s co-founder and CEO, he’s also the creator of Hashcash—the proof-of-work mechanism referenced in Bitcoin’s 2008 white paper. That proof-of-work system underpins the puzzles miners crack to safeguard the network and mint new coins.
Back responded to the New York Times piece on X, writing, “i’m not satoshi.” He pointed to his years working in cryptography, privacy, and digital cash as the reason for any similarities with Satoshi’s style or priorities. Back has maintained that Bitcoin is stronger precisely because there’s no public founder. X (formerly Twitter)
Follow-up reports have pointed to writing-pattern analysis and the stretch when Back kept quiet publicly in Bitcoin’s early days as the foundation of the case against him. After a year and a half investigating, Yahoo Finance quoted reporter John Carreyrou as “99.5%” confident he’d found the right person. The Times
Not everyone wants to make that leap. Aggelos Kiayias, who leads the Blockchain Technology Laboratory at the University of Edinburgh, called the link between Back’s research and Bitcoin “a clear connection,” but refrained from naming Back as Nakamoto. Sarah Meiklejohn at University College London pointed out that most users don’t pay much attention to protocol debates—ultimately, she said, “bitcoin stands by itself.” The Independent
Proof remains the biggest hurdle. Frederic Fosco, co-founder at bitcoin software outfit OP_NET, pointed out that “any identification will never be believed by everyone” unless someone actually signs a message using the original cryptographic keys linked to Satoshi’s wallets. That sort of digital signature is what many in the Bitcoin community would call definitive. The Independent
Markets haven’t reacted much. According to MarketWatch, a number of investors see Satoshi’s identity as mostly immaterial—unless it turns out to be a government official, or someone poised to move the coins. Lately, price moves seem more connected to geopolitical events than any buzz over Back’s name in the press.
This isn’t the first time the guessing game has gone sideways. Earlier speculation fixated on Nick Szabo, Hal Finney, and Peter Todd. Newsweek, back in 2014, tried to pin the name on Dorian Nakamoto — that unravelled quickly. Then there’s Craig Wright: his years-long insistence he’s Satoshi met a dead end in London’s High Court in 2024, with the judge later calling him out for having lied “extensively and repeatedly” to the court. The Independent
That backstory keeps things open-ended, despite all the speculation. Satoshi went silent back in 2011. Back insists he isn’t the person behind the pseudonym. And there’s still no signed message from those original keys. So, for now, the oldest riddle in Bitcoin is still hanging.
