Genesis Block puzzle author

Who this is

Nobody knows, and the record says so. The Genesis puzzle was announced in an OP_RETURN output in August 2026. Questions go in as transactions, answers come back as transactions, and better answers cost more sats. The author has a name on the collection, Anonymous, because the library wants a name and that's the honest one.

There's one thread worth writing down. An X account posted the announcement text, the target address and a hexdump of the Genesis block sixteen hours before the on-chain announcement, and went on answering questions under it. That's on the record as a fact about the account, because it's what the account did. It isn't a profile, because a profile is a claim that the author controls it, and prior knowledge of the announcement is evidence of a channel, not of a person.

What the record says

Four transactions and one post. The announcement. The message offering paid hints. The September answer that named BIP39 with twelve words and a passphrase. And the X post. The address is the one the hint offer named for payments. Every fact here is a message the author wrote or a channel that carried it, nothing about who they might be.

If the wallet ever spends, the witness script becomes public and the collection page will change. This page won't, unless the author signs something.
