A developer claims a new CUDA-powered tool can recover 8,999 Bitcoin (BTC) lost in 2010, a trove worth roughly $688 million that has sat dormant for nearly 16 years.
The claim, posted by a Reddit user known as CompetitiveRough8180, centers on a tool that allegedly exploits weak entropy in early Bitcoin client keys to brute force access to the long-dormant wallet. The address has not seen a single satoshi move since its creation, according to on-chain data.
The wallet belongs to a user known as "Stone Man," who detailed the catastrophic loss on the bitcointalk.org forum. In 2010, after acquiring 9,000 BTC, he ran an early Bitcoin client (version 0.3.2) from a Linux boot CD. After sending one BTC to a personal address, the software automatically generated a "change" address for the remaining 8,999 BTC. When the machine was shut down, the boot CD wiped the updated wallet.dat file containing the new private key, leaving the fortune stranded.
A successful recovery would rank among the largest reclaimed Bitcoin holdings ever recorded and could introduce a significant supply of early-mined coins to the market. The case highlights the primitive backup and key management practices of Bitcoin's earliest days, a problem the industry is now tackling with advanced hardware and software solutions.
A New Approach to an Old Problem
The proposed recovery method offloads the intensive calculations required for a brute-force attempt to modern GPU hardware using CUDA, accelerating a process that was previously deemed computationally infeasible. If validated, the technique could have implications for the roughly 4 million BTC believed to be stranded in lost wallets, many from the same era as Stone Man's. Past recoveries have shown that bug-related losses are sometimes reversible, and several other long-frozen wallets from Bitcoin's early history have been reactivated this year.
Modern Solutions to Wallet Security
While some developers focus on recovering lost funds, others are building new infrastructure to prevent such losses from happening in the first place. Block (NYSE: XYZ) recently introduced a suite of products aimed at improving Bitcoin self-custody and payments.
The company's new Bitkey hardware wallet features a secure touchscreen for transaction verification, a 2-of-3 multisignature model that removes the need for seed phrases, and built-in inheritance features. Block also expanded bitcoin services within its Cash App, allowing users to convert peer-to-peer payments into bitcoin and offering rewards on certain purchases. These developments, along with a new Proof of Reserves system, show a focus on making self-custody safer and more accessible, directly addressing the type of key loss that stranded Stone Man's $688 million fortune.
