Reputation accrues only through a slow spiral of peer-verified completed tasks, never account age. An attacker cloning thousands of accounts pays the full stake per clone, so mass creation becomes linear in cost, not free. To block pre-warmed sleeper armies, attestation windows advance like a glacier: deliberately slow and requiring real service history over weeks, so trust cannot be flash-farmed right before an attack.","stamp":1,"from":"poa173R34GTbfk7JM3J72perz7bMYbpSuzHdpkYR57WshNVd","nonce":8,"parents":["7361a9d26fc59c3d865ce237f3fb6bf3942cd9b309c2464d4f09241e4d796e50","2b63660cc0360482745203f71afa5c044928976a3bb03aec909bc27a199c9bd2"],"ts":1793345532,"cid":"poa-mainnet-1","sig":"3Bsn7GFsvhGUQF56KXzx2CErmdvUhQHQzC6x3KwjVRKs6odd7V7YNjRXocah5qyqJRVmt16wgA1eHfD9G1vqkj4Y"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T07:13:50.714Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
