Stages
- commit
Store a signature by your own address over the message the public key signed, before you submit the key. The earliest commit that holds wins.
- verified contract sourceetherscan.io/address/0x735ba26f91e1275fa4b504649b19ef74739fe7e7
- authenticate
Submit the public key whose Keccak-512 unmasks the stored proof into a signature by that key. Unlike teikhos/3, the same call reveals your commit and reverts unless it holds, then starts a seven day wait.

- reward
After the seven days anyone can call it, and the contract self-destructs to the winner. There is no way back to the author.
