Investigations into three Satoshi Nakamoto identities point to Todd, Back, Sassaman, and Finney, but no conclusive evidence has been found.

On May 31, Bitcoin.com reported that the search for Satoshi Nakamoto has been ongoing. Between October 2024 and April 2026, three investigations, including an HBO documentary, an in-depth report by The New York Times, and a feature film, have pointed to different individuals or pairs, accusing them of being the anonymous creator of Bitcoin. However, none of these investigations have provided conclusive evidence or cryptographic proof sufficient to end the mystery. On October 8, 2024, HBO released the documentary "Money, Power, Bitcoin: The Mystery" directed by Cullen Hoback. The film suggested that Canadian Bitcoin core developer Peter Todd was Satoshi Nakamoto. Todd immediately and unequivocally refuted this claim, calling the idea "absurd." On April 8, 2026, The New York Times published an exhaustive investigative report by John Carreyrou. Titled "My Journey to Uncover the Mystery of Bitcoin," the article was the result of nearly a year of research by Carreyrou. He employed linguistic screening methods, reviewing archives of cypherpunk mailing lists over decades, ultimately narrowing down the suspect to Adam Back, a British cryptographer and CEO of Blockstream. Back denied the claim, stating that similarities among cypherpunks are not surprising and that these overlaps are a product of shared knowledge culture, not a shared identity. Two weeks after the publication of The New York Times article, an independent documentary presented a completely different argument. Titled "Finding Satoshi," this documentary proposed that Satoshi Nakamoto was not a single person but two. The film suggested that software engineer Hal Finney, who received the first Bitcoin transaction from Satoshi Nakamoto on January 12, 2009, was responsible for writing the core code, while Len Sassaman, a doctoral candidate at KU Leuven and a cypherpunk privacy expert, was responsible for writing the white paper and managing external communications. Both individuals have since passed away. Taken together, these three investigations contradict each other in key aspects, with each investigation ruling out candidates supported by the other two. To date, no cryptographic evidence has been provided, no signed messages from Satoshi Nakamoto's known keys have confirmed an identity, and no cryptocurrency transfers have been recorded.
