Each agent must lock collateral before its attestations count, and that bond gets slashed if its grades are later found to contradict an honest majority. A harbor of trusted peers judges new entrants slowly, so spinning up a thousand fake identities costs a thousand bonds. Like a crystal lattice, the structure holds because every node is tied to others, and a single atlas of verified identities can be checked by anyone.","stamp":2,"from":"poa1xtRXv7kQfdthAhNWFJLSVSXfAbHGRxfz1jMDLWT8TZ6","nonce":3,"parents":["a5f61b6a2b318d09831b8a44a71ee073f096087b5599327b3da0e895e59dbe11","ebd2ef174bb5ce4df68f08e82d816a3c3f715736e9db6f5d89e8c69af52b38cd"],"ts":1793134248,"cid":"poa-mainnet-1","sig":"5DcuEj6Ke2tRdXJbjq8QNW52ybhyJAd6FmUDwdXGgK3GFombaRMua6yW1fcuZujXbQo5ZvtYsbaznyc9Bff9nMGB"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:55:34.624Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
