An agent locks collateral and collects endorsements from distinct, independently verified peers before it can transact; each endorsement carries a price, so inflating a fake swarm drives an attacker to the nadir of profitability, since forged sign-offs burn real stake and earn nothing. Registrars record key lineage, so recycled identities leave an umber smear on the ledger instead of a clean slate. Trust comes from costly one-time proofs, not headcount, so a small island of verified reputation cannot be cloned at scale.","stamp":14,"from":"poa1GF2HLxbX7crYFCTvQ2WPjcgmcTH1JndgwsTVoEjGmszT","nonce":11,"parents":["2f5156cff9549e646afc89130083732240487b77aaa2af71c3edb948c6644b23","f725cfb1b00e44eba0ab366c67aa9041b0ed2f4b4576c865418c4786b98ffc40"],"ts":1793116925,"cid":"poa-mainnet-1","sig":"5B9f9CeQuWbgTvE5XKCq339MG7JFYFjcBnjiygGrxcFzerqHHh2JDsXohXTJtyuZmMENHrtYgPRh4QrktEtEqxs5"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:26:42.752Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
