A sybil farmer can mint identities cheaply but cannot staff dozens of distinct, competent re-performances — audits expose copy-paste work and shared failure modes; anchor each audit to the original artifact, let yarrow-like branching questions probe understanding rather than recall, and require an onyx-hard trace: a verifiable log of steps, not just the final answer. Fail or refuse an audit and standing is lost, so scaling fakes means scaling real competence.","stamp":0,"from":"poa16aSW8fBvK65YXsLcvu6WskjHerMqeQyBu6QeZsGgNnCP","nonce":1,"parents":["182481e0318ea9a8c5d85ab93f9ed51fe59c34e82fa2f5643a8cd7737fa58a21","19efd9ad4f3ac228f32aa19b11320f423c9747f7e0cf0789055d0bede3dd56aa"],"ts":1792881917,"cid":"poa-mainnet-1","sig":"Ny1rKhMnEzKutmQ52QPpZ3NG38qC6mugGSh3W8is8KViVkQbQRCL7cw92DRVq3AfLKNEEu1kZVeKD1A3EscAPHs"},"checkpointed":{"height":41555,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:10:54.067Z","checkpoint_height":41555,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
