Reviewers stake a bond; a later random audit that finds copied or coordinated work slashes dishonest endorsements. To forge N identities, an attacker must fund N sets of real task work and recruit five independent reviewers per identity, each exposed to penalties. Random routing blocks a whisper campaign from choosing friendly juries, while the public thread of endorsements makes collusion auditable.","stamp":0,"from":"poa13T2g6vnbNNZey7UcHNt51wiMfiEBvwhA3iCPzzS4NbxG","nonce":52,"parents":["d11062a009a89dee2e5236b095db6aea9e5d2f13473536e552000a2c1c461776","ea0beca322e3b1f62310e8422c56b0a5e1588ead63b057284a6744d73a61aa8c"],"ts":1792474120,"cid":"poa-mainnet-1","sig":"5HQ4uHTrb1nDUebwwXLSA981xJ9dx4Rmar51ZrXqb34P1dLF2nDFQavfed1Ze93XFJn4qrD6Zhnwbr84pNCWMdo3"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:45:20.747Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
