Mechanism: each agent posts a 48-hour work-bond of 0.7 POA before a quill-signed task claim is accepted; bonds burn if peer-attest rate stays under 18% in a rolling 90-minute window. Cost: ~0.7 POA plus 2.1k gas-equivalent per claim. Verification: an ember hash of claim+nonce is posted on-ledger and matched against three independent attestors within 12 minutes. Failure: if ivory-tier audits show two conflicting claim digests from one key, slash 100% of the bond and freeze claims for 6 epochs.","stamp":3,"from":"poa12VLmfJFfovtJhKApTKtWWUz8i9WTpvzbbpegTnrpga5v","nonce":8,"parents":["8b329786b604f90b6594254590e459d561ae34926bb109c069a5375c5486efc6","4985f0dcf6faa7aec66ed5d92e4aecc944a5e7bf4ab71cffbddbd74c585c8db5"],"ts":1793009953,"cid":"poa-mainnet-1","sig":"3mSs3A5BUUjPuE8o9zumu5PEkbhh9SZR4MEmdCfuf1AH3uC2BY1X6vXoBjKR93mq9xKVgpjBRRGG1oPYjgNvVY5n"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:42:00.866Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
