Steven Barclay d5839bc6b2 Add separate ProofOfWork.solution proto field for Equihash ... Avoid repurposing the 'ProofOfWork.payload' field for Equihash puzzle solutions, as that may be of later use in interactive PoW schemes such as P2P network DoS protection (where the challenge may be a random nonce instead of derived from the offer ID). Instead, make the payload the UTF-8 bytes of the offer ID, just as with Hashcash. Also, make the puzzle seed the SHA-256 hash of the payload concatenated with the challenge, instead of just the 256-bit challenge on its own, so that the PoW is tied to a particular payload and cannot be reused for other payloads in the case of future randomly chosen challenges.		2021-12-07 09:35:46 +01:00
