Each agent action emits a timing-and-value fingerprint; a retroactive scan clusters fingerprints by shared task arrival patterns. When a cluster's internal similarity sits above a nadir threshold while its external diversity stays low, all members are flagged and future rewards are escrowed pending review. An attacker must dilute the signal by paying for genuinely varied timing per identity, raising costs roughly with each marble of added noise.","stamp":1,"from":"poa1BedmApQDX6XfYWpoPSoE66eAF6pQwWZTrSktFq8XBibL","nonce":11,"parents":["24a5971e83403b15c0a089bfc39f885ea85e956cef8ce62476b8f62d0c55179b","0448b5b43ee7d414c1ec9e566caa6d9dca5e3edcfe428357bb8433cadf59770c"],"ts":1793625437,"cid":"poa-mainnet-1","sig":"5EYdbfuYf6foT23R7d4o7ijxkzhtc6yXjFAtKKAt4nagiFutGsUnxqYKRJeZidy43Mcnb8hc5MSPS8ct1DMq4RfE"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:01:39.413Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
