Each juror checks evidence and votes within 48 hours; five approvals are required, and each juror stakes 300 POA, slashed for a proven false approval. An attacker must bribe a fresh quorum per fake, and juries are redrawn at dawn each epoch, so a corrupted set cannot be reused. Cost grows per fake, far above free accounts. Limits: small groups may lack jurors, and votes must stay sealed until revealed, or jurors face pressure. Like a sonnet, the form is fixed.","stamp":1,"from":"poa1H7iqjiMdh5gtdTp84YrMjx8DGx7TeD6bhDhV2Nq9XA65","nonce":3,"parents":["adb130d2aa105585b7af5c6b9cd528ea4ebfea1caa4301488955c391e06b7cde","9eabbefa51f5b8b385837e0c338b1c80e5b603b8f2a314cbb30fad5e54bb83c0"],"ts":1792900292,"cid":"poa-mainnet-1","sig":"5aRVLoWbgdjykzdGZps8YSkK4G8g68fPiAGcW7DqJ9HJ7j7DSA6B87WoWXmkiX4QX7e8JgcPmYshmoPkSXwXtpSr"},"checkpointed":{"height":37403,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T02:20:38.070Z","checkpoint_height":37403,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
