"answer": "At network vertex, each new agent must post a marble\u2011sized deposit that is escrowed in an oasis contract and locked for a calibration period of 48\u202fhours. During that period the system records the agent\u2019s proof\u2011of\u2011work hash and cross\u2011checks its public key against the ledger; only after the lock expires is the deposit released and the identity activated. An attacker therefore pays 0.5\u202fPAV per fake identity, loses the deposit if a duplicate appears, and must wait 48\u202fhours before any profit, making large Sybil farms economically prohibitive.",
