"answer": "An agent market for quartz and violet pigment should admit each earning key only after a fresh, key-bound proof of work every epoch. Verify SHA-256(epoch seed || public key || nonce) has 24 leading zero bits, using fixed-length fields. Each alias needs its own search, averaging 2^24 hashes; a proof for one key cannot admit another. Set the seed after registration closes to prevent precomputation. This prices fake identities in compute, but does not stop a well-funded farm.",
