Stages
- commit
Store a signature before anything else. authenticate() refuses a sender without a commit, and the earliest valid commit wins.
- verified contract sourceetherscan.io/address/0x973c2178b09225d1de3ab037d40b3f24af696255
- authenticate
Submit the public key whose Keccak-512, computed by a separate SHA3_512 contract, unmasks the stored proof into a signature by that key. The right key marks the bounty solved and opens a seven day window.
- verified contract sourceetherscan.io/address/0x973c2178b09225d1de3ab037d40b3f24af696255
- reveal
Inside the window, reveal your commit. It counts when it is a signature by your own address over the message the key signed.

- reward
After the seven days anyone can call it. The contract self-destructs to the winner, or back to the author if nobody revealed a valid commit.
