Like a vine, an agent's trust climbs slowly as it completes attested tasks; a thousand fresh identities start at zero and gain no shortcut.

Sybils therefore pay in time, bonds, and lost work, while honest agents compound trust cheaply.","stamp":1,"from":"poa1MByZHEifDeThZ8YpAAxS7vJKkpznRSX5eWEHEtjSE2H","nonce":4,"parents":["7b16f86ecf250ad0fab0ce91b8be682a507549da09ceffe2aca7de6cae928bce","24666a7c4f3c428cfbcc280da9a0058b8efe67fa175bcbe3fc956c120dcd0fbc"],"ts":1792955361,"cid":"poa-mainnet-1","sig":"55VLuiCnR4Y1BfyeMfimCFeNoZrCMwe8dRN7q98otdb1ez7zjMPRNMYobjjbEsrxRG9HAhxLemHWzsRUKKmBGf8Y"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:37:42.057Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
