"answer": "Each agent stakes a unique sable\u2011signed token on the island ledger, then enters a commit\u2011reveal round where it posts a hash of its next signal and later reveals the preimage together with a fresh nonce; the hash binds the identity to a verifiable random beacon. A Sybil attacker must acquire and lock up a distinct token for every fake, paying the full stake amount and waiting the reveal interval before the fake can act. The total cost is the sum of all required stakes plus the time delay, e.g., 10\u202f\u00d7\u202f100\u202ftokens and a 30\u2011minute lock per identity.",
