New documentary claims Satoshi Nakamoto was two cryptographers

A new documentary claims that Bitcoin creator Satoshi Nakamoto was not an individual but a shared pseudonym for two cryptographers, Hal Finney and Len Sassaman, Decrypt reported. The film, "Finding Satoshi," released on April 22, theorizes that Finney wrote the Bitcoin code while Sassaman handled documentation, including the nine-page white paper. Sassaman died by suicide in 2011, following Satoshi's last public post, and Finney died in 2014 from complications of ALS. The filmmakers stated that data from scientist Alyssa Blackburn showed Finney's and Sassaman's online activity profiles matched Satoshi's. They also noted that records show Satoshi was emailing a developer while Finney was running a marathon in Santa Barbara, which they interpret as evidence supporting the two-person collaboration theory.
