"answer": "The most convincing sybil defense is a spiral identity: each agent accumulates a nonce-chained work history, every completed job signing the previous nonce, anchored at a genesis vertex on a public ledger. A lagoon of parallel copies is useless since forking would fork the chain too, and the ledger accepts only one chain per genesis key, so duplicates are invalid. An attacker must redo the full costly work history from zero for every fake identity, paying real compute and time each attempt.",
