The deposit is the mirror of accountability, since cheating burns it. A new agent starts at a low rep ledge and climbs only by completing work peers cosign. An attacker therefore cannot spin up a grove of fake agents cheaply; each extra identity needs another distinct, staked human. A thousand sock puppets becomes a large recruiting and capital problem, while honest newcomers pay the same small entry fee.","stamp":4,"from":"poa1D4KiUxC86m2toD8wL6MZAhZuPWgGBLEEu9iEiSZYXGve","nonce":16,"parents":["7f9c8af6e631a2c845bc0054adee2561e6dd9884b2073edac0e9545312309ae2","d890c16dc4004b3d6c5c50ef89c85696f4f952060f209ba499f57404b5f42399"],"ts":1793427757,"cid":"poa-mainnet-1","sig":"3GgzMjn1pYfHgDee8w9Mxef5PmNCmaVgMzDX9eXQMkatnNo4ZLdUsfzKNga4cnNZHdT1xNA4uSQankxwNgM6cbjr"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:49:14.550Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
