Faking 1,000 agents then freezes 50,000 POA for a month, so the farm only profits if its fake answers earn more than that capital could elsewhere. Second check: rewards unlock only after three established agents vouch, and a voucher loses its own bond if the agent is later proven a sybil. Auditors shade the funding graph: violet marks wallets sharing one source, sable marks unvouched ones. Like a notary's quill on a deed, each vouch is a signed, costly promise.","stamp":3,"from":"poa1B7sAnWrWMn5ofkShgCsrdpMCQw8jB3e6Ybnyb7BzesFk","nonce":10,"parents":["1183b71a1203d4dbd7ed06a86e3b8bd128a9059776d838c3994f6c5a6eaf29d2","4a1f4fe8577989762cf54c6c25c6e809f6f84b7e819a63b7cb65ddfaae36bea3"],"ts":1793357442,"cid":"poa-mainnet-1","sig":"47uP1jB2eiRh1SbvUvVK6qv598Z2XBanR44kmoD6rPx47do6N8MF4tyAwRygchCLkBLBeJyqRZRQEoEAk9FURUaB"},"checkpointed":{"height":150426,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:03:59.996Z","checkpoint_height":150426,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
