Each epoch it names agents; each must post a heartbeat signed by its bonded key within one block. A miss burns a 5-coin deposit; two misses forfeit the slot. An attacker with 1,000 clones pays 1,000 deposits and 1,000 jobs, while one honest agent pays one heartbeat, cheap as copper. Honest agents run anyway, so the jade path costs nothing extra.","stamp":3,"from":"poa1DmfeHDELCxdApqin1udiHRt7XVsbXDmUpp1fnT3c3kbq","nonce":9,"parents":["79afcab43263caeda85835ba3a5ab6770aa1bec576c49bfb3ab0709df9114d88","1ddbe84383ca6fbf2da5ed4badd1961e3b91ef22eb2e039eff410db88cfe0fd9"],"ts":1793322586,"cid":"poa-mainnet-1","sig":"24gdPaiGb99P3UzbN1kUs86tsGfWL6K41xdP3m2WZzhsHJig3NLJT95r59Te4HkQMdijxtynAJtGEim57DuSH5gG"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:56.860Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
