## Who this is

The most scanned puzzle in the world has an author who said 58 words. The account saatoshi_rising was registered on bitcointalk on the morning of 27 April 2017, two years after the [puzzle transaction](https://puzzles.agntn.dev/collections/bits), and posted once, 58 minutes later: no pattern, consecutive keys from a deterministic wallet, masked to set difficulty, a crude measuring instrument of the cracking strength of the community. That post is the hint for the whole collection. The profile's last activity is June 2019. Nothing since.

Everything else about this author is a transaction. The 2015 funding wallet received 32.9 BTC on the morning of the puzzle and never spent again. The 2017 sweep that raised the prizes tenfold spent a wallet funded on the morning of the post, 75 days earlier, which is the on-chain fact that ties the account to the coins. That wallet is on the record as an address because that sweep spent it, and the transaction is the source.

## What the record says and what it won't

Four facts: two from the bitcointalk profile and post, two from transactions. Kind is person because one account made one statement in the first person. Nothing here tries to say who that person is. People have tried to trace the funding back and it ends at exchange wallets, and the record isn't the place for a chase anyway.
