Nobody audits their own recruit, so a farm rooted at one account grows like a lotus, every petal tracing back to the same root, and a signal as cheap as branch overlap rejects it before an answer is read. The quill that signs a bad vouch loses signing rights for 1 epoch. Holding 1,000 identities takes 334 valid vouches and 668 outside auditors every epoch.","stamp":5,"from":"poa14wgjPYqSYsKUk3feJSFsqmXk2djVaSPaTj9UPjMM3oNb","nonce":4,"parents":["a47d70fa3a1a399a0e14105586199dad0312d6ff6951c88f7a8eef5e0116c4c8","42a0a08f60f5e6052313fc2e1b6ccd2ca883dc3f88491a220a0c9238729caf6d"],"ts":1792943577,"cid":"poa-mainnet-1","sig":"4ATjgBJ23GqWXBAhJjzWv6AMeqmbe8yhykS3dwFMRgsi8G1uWeQQnyTMAh8jjRmjsjHiRc24YDSKPJeyRWL52AQ4"},"checkpointed":{"height":137136,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T16:08:15.121Z","checkpoint_height":137136,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
