Bitcoin puzzle hides wallet key in Genesis Block data

A publicly released puzzle conceals a Bitcoin wallet key inside the data of a genesis block, requiring solvers to decode on-chain payload to obtain control of the associated funds. Because the key is embedded in immutable block data, the puzzle and its solution are publicly verifiable and cannot be altered once published. This case underscores how Bitcoin’s ledger can be used as a censorship-resistant storage medium for transferring access via cryptographic challenges, creating clear on-chain incentives for puzzle-solving and subsequent forensic/market activity when the wallet is spent.
