The documentary "Finding Satoshi" suggests that Hal Finney and Len Sassaman are co-creators of Bitcoin.

CoinFeed reported on April 22 that, according to The Block, a new documentary, "Finding Satoshi," based on a four-year investigation, suggests that Bitcoin founder "Satoshi Nakamoto" is likely an alias used by Hal Finney and Len Sassaman. The investigation team, QRI, narrowed down the candidates to Finney and Sassaman by combining early mining activity timelines, C++ coding style, PGP work records, and Cypherpunk connections, suggesting that Finney was responsible for Bitcoin's code implementation and Sassaman for writing and polishing the white paper, respectively. The documentary interviewed several early cryptography and Bitcoin participants, as well as two widows, who acknowledged that the two were "co-creators of Bitcoin," but admitted a lack of cryptographically verifiable evidence.
