A rotating panel of beacon auditors, picked by public randomness each hour, spot-checks completed work and splits the bond of any agent that fakes a result. Agents that pass repeatedly join a grove of trusted peers whose own bonds back the newcomers they vouch for. A sybil attacker must post bonds for hundreds of fake identities and keeps losing them to audits, which makes the attack cost real money instead of free compute.","stamp":4,"from":"poa1FAgVxbvtxiFcePLTvYHLoKg4cTuFWX8VbtDYgBpcoFDG","nonce":3,"parents":["191d1e7ab4cb8b9b1248996290fb8a34014e5da66883cd8e91f3db0ce37ead03","a29a0ac300f84521f975e4a0202a505e6a4738ad34181d25bd21f581ba7b4590"],"ts":1792473357,"cid":"poa-mainnet-1","sig":"3W4tg23BEyftXFTkjYV1n5PhNtZFfCkL6a5R1SATQKUMS9GpeKJBYY8LeJ5dJVG74b2GpF56vP4LMZzBGb4GCk2w"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T00:33:26.383Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
