Bitcoin: Is creator Satoshi Nakamoto still alive? Adam Back responds

For over fifteen years, a question has continued to fuel discussions in the cryptocurrency ecosystem: what really happened to Bitcoin and its creator, Satoshi Nakamoto? As debates around the BIP-110 proposal still divide the community, Adam Back revisited this mystery during a conversation on X. The CEO of Blockstream believes that no conclusion can be drawn about the fate of Satoshi Nakamoto, reminding that the circulating hypotheses are based solely on speculation.

In brief

• Adam Back claims that there is no evidence to confirm whether Satoshi Nakamoto is alive or deceased.
• The last known public message from Satoshi Nakamoto dates back to April 23, 2011, before his complete disappearance.
• Adam Back's statements come as the controversial BIP-110 proposal divides the Bitcoin community.
• The identity of Satoshi Nakamoto and the fate of his bitcoins remain among the greatest mysteries of the crypto ecosystem.

As discussions about the security of the Bitcoin network intensify around the BIP-110 proposal, another historical question resurfaces: that of the fate of its creator. Adam Back, CEO of Blockstream, recently reacted to a post published on X regarding Satoshi Nakamoto. After accompanying the early stages of the project, he suddenly left the public scene in April 2011. In his last known email, sent to developer Mike Hearn, he explained that he was now focusing on other projects and stated that the development of Bitcoin was in good hands.

Since that final message, no communication officially attributed to Satoshi Nakamoto has been made public. This absence has fostered the emergence of numerous theories about his identity and fate. Some suggest that he may have passed away, while others believe he simply chose to disappear permanently from public life. Adam Back, however, reminds that no concrete evidence currently exists to confirm either of these hypotheses.

The discussion arose after a post by Matteo Pellegrini, CEO of Club Orange, who claimed that "Satoshi Nakamoto would support the BIP-110 proposal today if he were still alive". Adam Back immediately contested this assertion, responding that there is no evidence to suggest that the creator of Bitcoin is deceased:

He even emphasized that this possibility remains conceivable, but it is impossible to demonstrate with the information available.

Thus, the Blockstream CEO summarized his position by explaining that "all hypotheses regarding the survival or death of Satoshi Nakamoto are purely speculative". This statement comes as Back had already rejected the BIP-110 proposal, which aims to temporarily limit non-financial data recorded on the Bitcoin blockchain. The text is to be reviewed before the beginning of August, but it currently enjoys limited support from miners.

The silence of Satoshi Nakamoto has now lasted for about fifteen years. During this period, no transactions from the addresses attributed to him have been identified. This situation fuels several scenarios, none of which can be confirmed. Some believe he may have destroyed the private keys granting access to his assets.

Another theory suggests that these bitcoins are still under his control, having not been moved since the network's inception. Meanwhile, the true identity of Satoshi Nakamoto remains unknown. Adam Back himself is sometimes cited as a potential candidate, notably because he was, along with Hal Finney, one of the first recipients of an email sent by Satoshi Nakamoto. His work on Hashcash, developed in 1997, is also mentioned due to its connection with the proof-of-work mechanism used by Bitcoin.

The mystery surrounding Bitcoin and its creator continues to fuel debates without providing a definitive answer. As long as no new evidence emerges, the various hypotheses are likely to continue coexisting, while discussions about the legacy left by Satoshi Nakamoto will remain at the heart of the ecosystem's news.
