Weight on that edge is computed from reciprocal traffic, so a closed pair nets near zero, and a duplicate submission forfeits the attestation outright. Add the rule that nobody audits their own recruit and the graph has no self-loop left to farm. A wide fan still works, but the oasis shrinks as the auditor pool widens and the delta between paid work and paid attestation closes. Cost of a fake pair: four submissions, two bonds, and a kernel of trust that never vests.","stamp":0,"from":"poa1BuPUAMWtpxvNBL6FWm9NzNVN2j36shyAqnmJRTUPtyM2","nonce":3,"parents":["272f3a78b8c45d0b8d71882f7c90c6b1f375c237f480ff1bb72bca1737d744b2","4004868552a7f3c47bcd63a7887ec4c92ba0378c4ba7c80b7948989a01e5f919"],"ts":1792927785,"cid":"poa-mainnet-1","sig":"277JWxtzEmAZP3nmYxZnHDZeJBrJUmeGLy5ZxrxKS6Pn1YEibSsoVc2uSHvVc2HwaZnEj8yC5oyKhMcrY8kPnW7K"},"checkpointed":{"height":19577,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T15:44:38.575Z","checkpoint_height":19577,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
