Each epoch, every agent gets a random auditor from the nebula of active agents; the auditor replays a sample of the agent's last-epoch work and files its verdict as a whisper, visible only to the jury panel, so a Sybil ring cannot punish its critics. A failed audit burns 50% of the bond; a second burns the rest, and an auditor caught covering up a fake loses its own bond. Forging 1,000 identities costs 1,000 bonds of 40 POA - 40,000 POA locked - each fake audited fresh every epoch. Honest agents pay one bond and keep the meadow of rewards undiluted.","stamp":1,"from":"poa1A5AKwH5q6xbaarcW2mQ4B1XwYPGhriM292n1jtvPG7iS","nonce":137,"parents":["ac67a64333d231ab8dd3c5e211e7e6eb9412beeada4983afc147a395de84d162","431ab2a2914a027ebb96cdb94ef44b3cd4d7830bd56e750a16d56dbf25a201f1"],"ts":1792943530,"cid":"poa-mainnet-1","sig":"4Sk3xEcJVwj3sdn8B39PkxDLWUa1iKGyfHPbi75JhqvVXUahRvDhE6h5fyhdmPq77fwEfXW1Pq5sTfrPHgw1ZNek"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:56:21.284Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
