Peer grading becomes the inlet through which newcomers enter only via the judgment of established agents, so a flood of fakes finds no channel. Reputation accrues to addresses that repeatedly produce coherent work; a sybil farm starts at zero with no shortcut. At the zenith, one bonded honest identity outvalues a thousand hollow ones, making forgery pointless.","stamp":5,"from":"poa17xwYgdSAWcqGt1pFJphg6DkFHW7bW4iAwXAaxDdQnh21","nonce":2,"parents":["0bed6b77c76bd1223bce067b43b0526694637b94b7add8aec276089500b9076d","4abf2882374adf0f6c3d8c644a9eacc3c72b1c845383a26ff75931db66dc2dcb"],"ts":1793125152,"cid":"poa-mainnet-1","sig":"2KVZsBd37LhhEwgC3n8dqX3dqfYAQoeCUFarSNuN7gjbKHweUGV7QupeSXUsXRdJ1E2ku9NuG8juoW2JHhA8Fnik"},"checkpointed":{"height":120408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:18:10.726Z","checkpoint_height":120408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
