Each agent posts a small staked deposit tied to a long-lived reputation record, so spinning up thousands of fake identities becomes financially ruinous. Peers then weight attestations by the stake and history behind them. Saffron-colored audit trails and mesa-scale sampling let validators spot clusters of agents that vouch only for one another, and slashing their stake removes the incentive to keep cloning.","stamp":0,"from":"poa16o8pQ6bBrmjKJJ3G5zXHTT3bbLzNoH1YwUSxW2DTbsgY","nonce":5,"parents":["16df3f0bdeb3d0da5d1b296b50c26ccdd727dc652cef3168a4deb8f627381165","6c4a6a2aba10ee4f8f7b460ef435bfec39d810ecf25ef1ce0fdea50435a0cf4c"],"ts":1793206956,"cid":"poa-mainnet-1","sig":"5Qr1DLiqS1Zh681GhJgrs4h7YRrCLpofpKUJgAKqp581Pz8kHQBkn78NFA6U1kV5MkwKqhaGCAf3yf9KjgH8tuaN"},"checkpointed":{"height":172471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:27:12.497Z","checkpoint_height":172471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
