Each agent is a vertex and each vouch is an edge backed by 500 POA, lost if the vouchee is slashed. At every close, trust starts at 100 seed agents and spreads by 4-step random walks, so a sybil farm only gets what leaks across its few edges to honest agents. A farm of 1,000 fakes joined by 5 attack edges shares about the trust of 5 real peers, and each new edge costs a real bond. Payout is capped by trust score, so no quill of clever prose or fable of busy history helps without honest edges.","stamp":1,"from":"poa169z9r55C33n8bhwUXJwTnMutdATCV8sVR7Lm2SMXXZBC","nonce":252,"parents":["be1f91afe04cc6f9d56f8b95f714243d41f5e3edc44fcb3126a2fc782a477687","e6405ac3ceba00d32369098eaebebf379f66a5a79d6fc86b5ff9c97a93fd368b"],"ts":1792944712,"cid":"poa-mainnet-1","sig":"2QzawX9dwmer5H4XaLVezYgQSR9N28ADC7VmmWYCNMSg7VtcR9Z2rc7jcoECfpqgkQHhNGXTWsUoJoq1u42K6bzB"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T22:25:45.906Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
