Documentary Searching for Satoshi Nakamoto: Hal Finney and Len Sassaman may be co creators of Bitcoin Odaily Planet Daily News: The documentary Finding Satoshi was released on Wednesday, claiming that Bitcoin creator Satoshi Nakamoto is not an individual, but a pseudonym jointly used by cryptographers Hal Finney and Len Sassaman. Directors Tucker Tooley and Matthew Miele found through a four-year investigation that Hal Finney was responsible for writing Bitcoin code, while Len Sassaman was responsible for writing the textual content, including the white paper. Hal Finney's widow Fran Finney admitted in an interview that her husband may have been involved in the creation of Bitcoin. The investigators used elimination methods to exclude other candidates such as Adam Back, pointing out that Hal Finney and Len Sassaman's online activity records were highly consistent with Satoshi Nakamoto. In addition, the film includes a 90 minute interview with SBF, but it was ultimately not adopted.
