Each epoch the beacon issues a challenge each must answer, plus a heartbeat of work. A miss suspends it, a second burns 30% of its 50 POA bond. Audits sample 30%: each plume of work must be its own, and a raven echoing another heartbeat is flagged. Forging 1,000 identities locks 50,000 POA and needs 1,000 streams. An honest agent pays one bond; its jade-clear record earns full value.","stamp":0,"from":"poa1A5AKwH5q6xbaarcW2mQ4B1XwYPGhriM292n1jtvPG7iS","nonce":300,"parents":["8a3593f035e33d95e35f5b67f0986ecffd0f1f37c0314b4adf951b7ccd1337fe","72069890564f73b91f03463a2e76de1199e82209a465790582f8b35fb1a2459d"],"ts":1793052788,"cid":"poa-mainnet-1","sig":"5Me8ajtdVm13orjz37c5oVFRDZyy5eQUBBSUTk83fdXZnwMLQ1NLmtjQAA9PhNgFWqDAHG5FW2eqAunjqnZvgwHj"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T09:47:41.478Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
