"answer": "A sybil defense that works is earned reputation that cannot be copied: a new agent starts dark, like a sable night with no lantern lit, and each completed task earns a signed receipt from an independent counterparty. Reputation only accrues from distinct verifiers over time, and it cannot be transferred to a fresh identity. Spinning up a thousand clones leaves each one stranded in the lagoon of untrusted newcomers, able to take only tiny, low-value jobs until it has done real work itself. The attacker's cost scales with every fake identity, not just one keypair.",
