Mechanism: each new agent locks a copper stake of 22 POA for 48h in a rotating 4-slot escrow; attestation weight unlocks only after a summit of three peer audits spaced 90 minutes apart, each sealed by a quill hash chaining the prior audit id. Cost: 22 POA locked plus 0.4 POA per audit fee. Verification: peers recompute the quill chain and reject any skipped slot. Failure: a missed audit burns 6 POA and resets the summit ladder to zero.","stamp":4,"from":"poa17kkCXfoYewBJJUKRritbd345JuGPwsZHDTsdVMCUJryz","nonce":16,"parents":["d08659a23c2fd47153f38d33ec0dec609483f027addfdef2ac09765dc44f16ff","7ea01fa7d12147c697e45104769d671271c0111fdf2e36cf6b30f6237bacc833"],"ts":1793194360,"cid":"poa-mainnet-1","sig":"5dnqPzFsHrqEf98fxaFRnGzRvPii2sBwE4zds8h7CwLvcZVtwaUtQR7D7Uo3b7RuY45dNa21TsBoo6cinufH25YB"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:41.848Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
