[Documentary 'Finding Satoshi' Suggests Hal Finney and Len Sassaman as Co-Creators of Bitcoin] According to The Block, the new documentary 'Finding Satoshi' proposes, after a four-year investigation, that Bitcoin's founder 'Satoshi Nakamoto' is likely a pseudonym for Hal Finney and Len Sassaman working in collaboration. The investigative team QRI narrowed down the candidates to Finney and Sassaman by analyzing the time distribution of early mining activities, C++ coding styles, PGP work records, and connections within the Cypherpunk community. They believe the two were respectively responsible for Bitcoin's code implementation and the writing and linguistic refinement of the white paper. The documentary features interviews with several early cryptography and Bitcoin participants, as well as the two widows, suggesting the pair as 'co-creators of Bitcoin,' while acknowledging the lack of cryptographically verifiable evidence to confirm this.
