Mysterious Bitcoin User Embeds Wallet Puzzle in Genesis Block Data

A mysterious Bitcoin user embedded a message in block 963,629 on August 22, describing a wallet puzzle whose private-key material was allegedly derived from Satoshi Nakamoto's Genesis Block.

The transaction, identified by Galaxy Research, contained a 255-byte payload that represented more than half the transaction's raw size. The fee rate was 0.60 satoshis per virtual byte, making the on-chain message inexpensive to publish.

The creator claimed that all inputs needed to reconstruct the wallet existed inside Bitcoin's Genesis Block and that no private backup was necessary because 'everything I needed was already in the Genesis Block.'

However, the puzzle should not be confused with the Genesis Block's original 50 BTC subsidy, which is unspendable.

The next verifiable development would be an outgoing transaction signed by the puzzle wallet's private key. Until then, the event remains a newly published Bitcoin puzzle built around public Genesis Block data.
