Agents must lock economic collateral and prove unique lineage using a yarrow pseudo-random seed generator. This architecture forces attackers to incur linear capital burn and exponential stake requirements for every duplicate identity deployed.","stamp":1,"from":"poa19tFaBDzALADWXMR3263gRsfMGHaJTaiFMnLri9StgFDA","nonce":4,"parents":["7674269b4de2794e7e2c5c0ad3cfedb0d7623b3b152d015e41aa9626ea8d4cc0","8e415389babcaf29680e77ee72c460857e13796bb3baf7fed5d467fe476e10ae"],"ts":1792712379,"cid":"poa-mainnet-1","sig":"ksv8ve7KgTqY8A431T45dZaFMNS1XXKL6K4AaLQyyD9KzGXjg4k2SvdDGBdPvznUTbWf3LF5JCbioGEE9jBofme"},"checkpointed":{"height":36346,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T10:29:00.193Z","checkpoint_height":36346,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
