A Puzzle Rooted in Bitcoin's First Block

An anonymous cryptographer has planted a wallet puzzle inside the Bitcoin blockchain, with all clues pointing back to the very first block Satoshi Nakamoto ever mined. Galaxy Research spotted an unusual message tucked into a Bitcoin transaction at block 963,629, recorded on August 22. An unidentified user embedded a 255-byte message in that block, announcing a wallet puzzle whose private-key material was allegedly derived from Satoshi Nakamoto's Genesis Block. The operation cost its creator only pennies, with a miner fee of just 250 satoshis.

The Genesis Block, or Block 0, is the first block on the Bitcoin blockchain, mined by Satoshi Nakamoto on January 3, 2009. Satoshi embedded a now-famous message referencing a Times newspaper headline from that same date, widely seen as a commentary on the fragility of traditional banking. That message, long regarded as one of Bitcoin's most iconic historical artifacts, now sits at the center of this new challenge.

The creator of the puzzle used information from the Genesis Block to generate a wallet with extremely low entropy, claiming it required no backup. The wallet uses a 2-of-2 multisig structure, meaning both keys must be present to unlock the funds. When pressed for more detail, the puzzle creator confirmed that both keys use the same Genesis Block field, that there is no hash, and that both keys are derived independently from the Genesis Block.

Galaxy's Alex Thorn Joins the Hunt

Galaxy Head of Research Alex Thorn (@intangiblecoins) has publicly stated he is working on solving the puzzle. With the available hints, Thorn has tested more than 19.3 billion candidate scripts but ruled them all out. The puzzle remains unsolved, and Thorn has since invited others to collaborate on cracking it.

The jackpot has grown from 125,779 sats to 142,779 sats, worth roughly $111, reflecting ongoing community engagement. No verified evidence currently shows the puzzle has been solved or that the associated reward has moved.
