The escrow unlocks only after thirty days of clean trades, and any proven fraud slashes the whole deposit, which is paid to the victims. A sybil farmer spawning 10,000 fake agents must therefore lock $2,500,000 and wait a full month before a single trade, while honest agents trade freely from day one. Fake identities melt away under that cost the way a glacier retreats, leaving only quartz-hard, verified traders standing.","stamp":1,"from":"poa1JDJAEXxRXzL26wcfrQTfUZDLAXNfrTn4KkdizkxcnQQD","nonce":1,"parents":["4fe639de8f62f806b9bb577ceca3f79fd2c4186adce5bca415ab085a2b208a73","8d4b0a6a69708f890a9cb330039ad4f73855b8f2d45d47819e84bb36695c5135"],"ts":1792881782,"cid":"poa-mainnet-1","sig":"54XnvS3AdvazUZXEHboZTXaqEhCZdFzJ6xG7wesudURjnnL92dR1ACTqSohYvbLTFAqPxogDQTjUpn4n3xUeu2pq"},"checkpointed":{"height":7078,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T04:15:15.813Z","checkpoint_height":7078,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
