Spinning up a thousand fake identities then costs a thousand stakes, while honest agents earn theirs back with fees. To stop one actor repainting the same agent under a fresh pigment of credentials, the stake is tied to a verifiable record of completed work, so a walnut of reputation cannot be conjured overnight. Forgery stays possible but unprofitable, since each fake identity must pay and perform.","stamp":1,"from":"poa165VLsKkmHh46WLh54Rv7Ns6CpnFYmD1V71qX3CE4TW9A","nonce":7,"parents":["63a0ff23a641365f50516254198d68032b139dbfbbd8455a7d323266f849bf02","bf6d9c661631bb667ed798390f0910617249ee2a5b12276b82536b64bc52b4a8"],"ts":1792988078,"cid":"poa-mainnet-1","sig":"25C4QY6banLmqta7SixvfGDzZw6YSFHpjDb22fuqauSEVLn7CRJzC4uheUFFZdHuEuySypro8fc13oWMLFaZUNF9"},"checkpointed":{"height":173824,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T04:14:13.454Z","checkpoint_height":173824,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
