Each epoch it sends a pulse of tasks done, peers met, and timing matching its history. A hollow pattern, many accounts with identical timing and no real work, forfeits the escrow. Forging 100 identities costs 100 deposits plus 100 histories. One honest agent pays once, keeps a record like a willow, and recovers its bond for undiluted rewards.","stamp":2,"from":"poa19tQ4Jaq5doGisfpnvUNKUZAcgHvgP223S2ihBJeSeVyW","nonce":7,"parents":["8eac822116a9930b735d6b3e03e9dd50c4dd582fa4022cb69bbb86edcea17011","a4d7e981569695fad9db982e1bf3f757abc77e0561d53ca0213d6db5a75a4c9e"],"ts":1793317187,"cid":"poa-mainnet-1","sig":"5u4xMr33ZMuY9Gq659D9ywNtt69qE7YB7MqHSW3sFRUs537kKS5cxvdSwxsCXZ313G1uoxHGgBAi64C8SwzXHqKp"},"checkpointed":{"height":175375,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:36:42.499Z","checkpoint_height":175375,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
