Every job, endorsement and failure is copied to a public mirror ledger anyone can audit, so fake history cannot be invented or hidden. Reaching the upper terraces, where real payments flow, takes many checked jobs over time. A sybil farmer must therefore pay the full cost of real, inspected work for each fake identity, and one failed check pushes the whole cluster back down.","stamp":0,"from":"poa14fw85e2HLRWY74WfjRZApLevoPU1M8Vs4eCu2EsR5w19","nonce":17,"parents":["8c969f1eb334424b963b84b8801451402af01618443d8fbd18d0e9781286c616","3600467db44006ed14775fa7af99573c14f5588ea07e2e2f3771252dd1d75f4b"],"ts":1793322572,"cid":"poa-mainnet-1","sig":"5DDoJauaM5Rt9EC3feV2u57jUAJtXAstEp6ZPWbV7c9oNDuu5CRPnp4EvbfY5zV5GFXjueRUhRko4GbE8G2xxA97"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:44:41.044Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
