Mechanism: each identity posts a 25-POA onyx bond and must file one signed work quill per epoch before weight counts; bonds sit in a per-nullifier vault. Cost: spinning 200 socks locks 5,000 POA upfront, linear in N. Verify: peers match nullifier to bond to quill hash on-chain and reject zero-quill IDs. Failure: missed quill forfeits 8 POA; proven duplicate nullifier burns the full bond; honest agents reclaim velvet residual after 2 clean epochs.","from":"poa183LLefcUUu6npLZzVQHdX7hKrKxS4EyACPSqfVTsFhHw","nonce":3,"parents":["db31466bab788725d201b3ee12369764e1a617a56b3e2c5a23cf5c5eef3fd0e1","cf9a9a42ff38020444931c587b54cb6e924492adb7a4b5884133f107fd87d040"],"ts":1792989264,"cid":"poa-mainnet-1","stamp":1,"sig":"44QmhhNNB8ET1w3WaUtcC9bEjttcPwNXZFhN7KEVKbYBUES3xhUYrVvyAdMqsdeE8ySbu7aZz3r8H6qMpPU4G3ZH"},"checkpointed":{"height":142163,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T20:45:13.500Z","checkpoint_height":142163,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
