A new report published by The New York Times on April 8 has revived the long-running mystery surrounding the identity of Satoshi Nakamoto, the anonymous creator of Bitcoin.
The investigation suggests that British cryptographer Adam Back could be the person behind the famous pseudonym. However, Back has firmly denied the claim and says the theory relies on “confirmation bias.”
The debate over who created Bitcoin has continued for more than a decade. While several names have appeared over the years, none has provided the cryptographic proof required to confirm the identity of Satoshi Nakamoto.
The Investigation Linking Adam Back to Satoshi
The year-long investigation focused on the work and online history of Adam Back, the CEO of Blockstream. Back is widely respected in the cryptography community and is known for creating Hashcash in 1997.
Hashcash introduced a proof-of-work system, which later became a key part of how Bitcoin mining works. Because of this connection, many researchers have long considered Back one of the possible candidates behind Bitcoin’s creation.
The report also noted that Adam Back is one of the few people directly mentioned in the original Bitcoin white paper released in 2008.
Writing Style and Technical Similarities
Investigators also examined writing patterns from thousands of cryptography mailing lists. According to the analysis, Adam Back’s writing style showed similarities with the messages posted by Satoshi Nakamoto.
Researchers pointed to small details such as punctuation habits, technical terms, and formatting patterns. These similarities led some analysts to suggest that Back’s writing matched Satoshi’s more closely than other candidates.
Still, experts acknowledge that many early developers in the cypherpunk community used similar language and ideas.
Timeline Questions Raised
Another point raised in the report concerns Adam Back’s online activity between 2008 and 2011. During this time, Back appeared less active on some public cryptography forums.
This period overlaps with the launch and early development of Bitcoin. Satoshi Nakamoto disappeared from the internet in 2011, which has fueled speculation about whether the two timelines are connected.
However, Back says this theory ignores the fact that he remained active in other technical discussions during that time.
Adam Back Strongly Denies the Claims
Adam Back quickly rejected the theory after the report gained attention online. Posting on the social platform X (Twitter), he repeated that he is not Satoshi Nakamoto.
Back explained that he has always supported digital privacy, cryptography, and electronic cash research. Those interests led him to develop Hashcash and other technologies years before Bitcoin appeared.
He also joked that if he really were Satoshi, he would have mined far more Bitcoin in the early days.
Other People Linked to Satoshi Nakamoto
Over the years, several individuals have been connected to the mystery of Bitcoin’s creator.
Developer Peter Todd was suggested as a possible candidate in the 2024 documentary Money Electric: The Bitcoin Mystery, though he denied the claim.
Australian computer scientist Craig Wright also claimed to be Satoshi Nakamoto for years. In 2024, a UK court ruled that his claim was false.
Another early contributor, Hal Finney, often appeared in discussions about Bitcoin’s origins. Finney received the first Bitcoin transaction but passed away in 2014.
The Mystery of Bitcoin’s Creator Continues
Despite new investigations and theories, the true identity of Satoshi Nakamoto remains unknown.
Experts say that only cryptographic proof—such as moving Bitcoin from the early wallets believed to belong to Satoshi—could confirm the creator’s identity.
Until that happens, the origin of Bitcoin will likely remain one of the biggest mysteries in modern technology.
