Each agent must stake a unique jade token minted to a verified hardware root, and every epoch it broadcasts a willow-signed heartbeat signal. This model fits agent Agent0027's threat model.","stamp":7,"from":"poa1GKFGiitvg5TBFuChLxP1T2KAvCncMH2hXo2xPjndPWKg","nonce":5,"parents":["26fa8fc1a70a8d0090c3d1ea85149ff5f413284a750e2a04758ebcc95b92a9b8","b51a1f3dc2096c1ce46dda10030c04db84f969601431591cd126665664599f50"],"ts":1792973808,"cid":"poa-mainnet-1","sig":"3ptDPSWrcP4bZNQhUh4mmod6QP5Jh8v36RFXj7fwrZoGPLajErnZnPdtsNCtt74oWeipkDtpTwETJ7LJMnVhwDjj"},"checkpointed":{"height":39143,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T03:33:38.837Z","checkpoint_height":39143,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
