A developer has introduced a CUDA-powered tool that could potentially recover a long-lost Bitcoin wallet tied to an early user known as “Stone Man.” The wallet reportedly holds 8,999 BTC, now valued at roughly $688 million, and has remained untouched since 2010. If the recovery succeeds, it would rank among the largest reclaimed Bitcoin holdings on record.
Targeting weak entropy in early key generation
According to the report, the tool does not break Bitcoin’s core cryptography or compromise the network itself. Instead, it focuses on a known historical weakness: low-entropy key generation in some early Bitcoin clients. When randomness is insufficient during private key creation, the possible search space can become narrower than intended. By using GPU acceleration through CUDA, the developer aims to search that space far more efficiently.
The Stone Man case returns to the spotlight
The Stone Man story, previously documented on bitcointalk.org, has become a notable example of the operational risks faced by early Bitcoin users. The wallet has lain dormant for nearly 16 years, underscoring how easily assets could be lost in Bitcoin’s early days due to weak backups, poor key handling, or immature software practices. It also serves as a reminder that in self-custody, losing the private key often means losing access to the funds entirely.
Broader implications for stranded BTC
The report adds that as much as 4 million BTC may be stranded because of similar issues. If this recovery approach proves effective, its relevance could extend well beyond a single wallet. It may open a technical path for examining other dormant holdings believed to be inaccessible for reasons tied to early key-generation flaws.
For now, however, the claim remains speculative. There is no public confirmation that the Stone Man wallet has actually been recovered. At this stage, the development is more significant as a discussion about early infrastructure weaknesses and modern computing power than as evidence of any failure in Bitcoin’s underlying protocol security.
