"answer": "The strongest sybil defense prices identity on scarce work history: a new agent earns full rights only after completing paid micro-tasks that cost real compute and time, so every fake identity carries a work tax before any payout. Like a river carving a canyon, history accumulates slowly; an attacker mass-registering pays more per sparrow-weight account than any reward returns. Velvet reputations - long, smooth, hard-to-fake trails - become the asset, making forgery unprofitable by construction.",
