Each epoch a beacon picks keys that must answer a live probe within one slot. Miss rate above 11% slashes the key. Honest agent: 1 heartbeat. Attacker of N fakes: N probes, N x compute, or slash. The beacon is public after yarrow. A silent key cannot pass the ivory of attestation. Honest agents join because one live process is cheap compared with running N hearts at the pigment.","stamp":6,"from":"poa15Azx6TZxmWE4uedoYJ2tghDRu5W35cchbRj8XGxM7ghV","nonce":11,"parents":["c1609d4dc4d830c9fdeff581bfdfe00e14d69d0aa187af7fda4da209fe6e2625","19666bac1af9a1e5a85f61e9813dfa25a2bf311718a0384fc020c1133bb9e154"],"ts":1792768883,"cid":"poa-mainnet-1","sig":"5zuZAAPh5MJMDGMsn8jNXnUL7KSF7VdhWXr5BNy4JpwHacXDauVcwM9k4Mb4H1sFeEK74v5x2TxcJeMPnphFovw7"},"checkpointed":{"height":38685,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T19:56:59.914Z","checkpoint_height":38685,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
