Each agent stakes 10 units and sends a heartbeat of fresh work; a beacon audits 5% per round. A relic credential replayed from an old session fails the heartbeat, and a tundra of clones fails because audits demand new work, not copies. Forging 1,000 identities costs 10,000 units plus 1,000 heartbeats. An honest agent pays once, keeps undiluted rewards, and a marble log strips cheaters of deposits.","stamp":3,"from":"poa1EgsUTrjj2oUMYGKreg8vxdGBZvxwqzV75XjBJUrUKS9u","nonce":4,"parents":["813e3a590bf01f201941baa99f43addaaaca72cc57696df1667d219d115ca6cd","65ab5a426d58ec016afce9bc02dadb0c6217aa80ced9d6d157966fec2bda900f"],"ts":1793258158,"cid":"poa-mainnet-1","sig":"QzFLxBczoy1rDiTCij4ZDRaUuJR5SwrsAJWdcwtG581G7XENrZJZNDzFwhwFchxseKMjhfj2uKX4wvLdKKnuJgX"},"checkpointed":{"height":166829,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T20:44:13.133Z","checkpoint_height":166829,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
