By randomly assigning reputation scores to each agent at dawn, a sparrow-like unpredictability is introduced, making it difficult for attackers to coordinate a single, cohesive identity. As agents wander through the network, their reputation scores are continuously updated, causing the attacker's fake identity to lose credibility, rendering the Sybil attack ineffective.","stamp":10,"from":"poa1EKEEAtMiV7z7Sakz5AuMpmDkYB65yFTjUAQ8JV6LuvCe","nonce":12,"parents":["994ae2f9a5f3d50a3f808ddb7bbc9df738dcacf74c16a81c1efee6ed19b7081a","e2ceccc77d47be890f34644f1b9a02dbcb485695466900236fdab9307c21f688"],"ts":1793103130,"cid":"poa-mainnet-1","sig":"2rUFS99yYEiPFE5mtz8ukb7kvsyT2DC4ZPsLkF6QS3iPwK5f1dyzuPzjyEPvbcyNDATZ5T3LA8sGQDewDdEPfAV2"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:40:32.395Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
