I recently watched a new documentary that sparked heated discussion in the community, called "Finding Satoshi," which specifically explores the true identity of Bitcoin's creator, Satoshi Nakamoto. To be honest, this question has been hanging for over a decade, and finally someone spent four years conducting an in-depth investigation.

The core claim of the documentary is a bit surprising—they believe that Satoshi Nakamoto is not an individual, but a collaboration between two deceased cryptographers: Hal Finney and Len Sassaman. Both were key developers of PGP encryption software, with profound technical expertise.

The production team’s reasoning is quite interesting. They found that Satoshi Nakamoto often used "we" instead of "I" in emails, suggesting it might be a group effort. Additionally, they analyzed code style, writing habits, and even enlisted former FBI behavioral analysis expert Kathleen Puckett for stylistic forensics. Data shows that Satoshi was active during hours consistent with Eastern Time in the U.S., ruling out many European and Asian candidates.

The most intriguing part is how they interpret Jameson Lopp’s previous claim of an "alibi." Lopp said Hal Finney was participating in a marathon at the time—how could he be online simultaneously? The documentary explains that—because Finney was running the marathon, Sassaman was handling email exchanges, allowing the team to maintain the illusion of 24/7 activity.

The documentary also interviewed the widows of both men. Hal Finney’s wife, Fran, believes her husband played a key role in the creation of Bitcoin, while Sassaman’s wife, Meredith, talked about her husband’s obsession with privacy technology. These personal stories add warmth to the technical argument.

Interestingly, this conclusion is completely different from the previous investigation by The New York Times. The NYT claimed that British cryptographer Adam Back was Satoshi Nakamoto, but Adam Back has repeatedly denied it, saying that while he invented Hashcash, he is not the creator of Bitcoin. The documentary suggests that Back’s technology laid the foundation for Bitcoin, but his activity timeline doesn’t fully match.

Industry reactions are quite divided. An American exchange CEO said after watching that he believes the production team found the correct answer. Vijay Boyapati, author of "The Principles of Bitcoin," also gave high praise. But Cardano founder Charles Hoskinson has a different view, believing that Bitcoin’s greatest fortune is precisely the "absence of a founder." If Satoshi Nakamoto were tied to a specific identity, it could pose reputational risks.

I think this perspective makes a lot of sense. Satoshi Nakamoto chose to retreat early in Bitcoin’s development, handing over control to the community—this itself is a brilliant political move. For pure technologists, identity no longer matters. Bitcoin was originally created to fight surveillance capitalism, rooted in the cypherpunk spirit. Even if we now know it was Finney and Sassaman, Bitcoin’s decentralized essence still transcends its creators.

As regulations in various countries advance, Bitcoin has shifted from a mysterious digital experiment to an important asset in the global financial system. The mystery of Satoshi Nakamoto’s identity adds an eternal literary charm to this history, and reminds us of the pioneers who fought for freedom with code in the digital wilderness.
