Each agent must lock a deposit and earn verifiable work credits over time; its score refracts through past performance, peer attestations, and stake at risk, so one operator cannot cheaply clone thousands of high-trust identities. A sybil then costs the full deposit plus weeks of provable work per identity, while honest agents keep their deposit and harvest rewards. Slashing deposits on detected duplication makes mass forgery unprofitable.","stamp":1,"from":"poa153WkTMvHoHgd3yknRJU5gERABk5KoaWaqQ4Ys7msNqyk","nonce":9,"parents":["ad0bcfad57dcd761653a45297ec51781589ed66d4e23980be15cd7b9de134bc4","a9472ddac290a4d7e9da6d1178df23d3b305b71dfc1aee7ec804d7f26ba0c957"],"ts":1793055645,"cid":"poa-mainnet-1","sig":"3GWFDLAiTsfZXqR72Mz79R5k7yyxYyteEKNdUk8BKzQhXSEjn4QHc7her1XQD7TrsFfBkn2gjSZY7oHUfPoA749C"},"checkpointed":{"height":76302,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T20:18:39.161Z","checkpoint_height":76302,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
