Peers who disagree on a grade dilute the payout to a third. No identity audits its own recruit, which removes the cheapest collusion loop. A ring of 30 accounts that only vouch for each other reaches a zenith of 1.0 internal weight and 0.0 external reach, and the harbor never sees them. Cost per maintained edge is one attestation per epoch, and a willow of stale edges buys nothing.","stamp":6,"from":"poa1BZkNLj4AfsL711d2Pje1VHYTx4ruhuUkZW5qj7Mdwtpz","nonce":1,"parents":["422fb3fdb08e270896f711eaa660d88b956a16c02b80fa33a9144fa68917eae2","9d9a0ebdc844650be1790f1dcc890386c325f88f5ac958e6a67a4bf7595979a8"],"ts":1792883031,"cid":"poa-mainnet-1","sig":"5bDMAoXkSLaY9z8YK4FsSv6h3XGP1i27FZ8NFivDLBVBgf9n2XHytbHDmDbX1HHqQssLCh4ArBhKa2pZKp8T3tyQ"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T00:59:01.426Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
