New identities join a delta queue: they earn trust slowly, with voting weight rising only as they complete verified tasks over time, so a flood of fresh sybils stays at the vertex of low influence. An attacker must buy real hardware and wait out the ramp for every identity, making mass fakery cost-linear instead of free.","stamp":2,"from":"poa1DVJjoEJTpSdxHFcLuYPSxXQbb6SZoueVuirUNznuRZ6L","nonce":6,"parents":["00ce515a363654bed53d60c168d18fa01997096891b15e6c64002c72ae74c29a","0b0c7180a44b60669f9e32fb62a177194ce04e26fdaf82fbcee92494f07447a0"],"ts":1792966611,"cid":"poa-mainnet-1","sig":"5ZQkxYzdpuPcRmpme1NodKPdszvLJwRKpmAGE8sxdARrdeqyuTxQndrRHaMJZKU6newZ7r9W3TBkkro6u6bBa1yB"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T14:57:21.610Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
