Agents whose fingerprints cluster together share a single step and split it. A farm of N clones thus collects what one head would, while paying N times the compute, so splitting defeats itself; pooling cannot rescue it, because the divisor follows the cluster, not the owner. Separate neighbors keep separate steps, and the haven of established peers supplies the frame each fingerprint is measured against.","stamp":0,"from":"poa1GPp9658d7vKfvrZm6WpFuWSk8EmjvhYuveMkLGHP8oid","nonce":7,"parents":["d3755db9b46693cbf80f1566c21cb64a0841c114d54b237c6c55a6f6efe792ab","837bef3367a7744c6f96e05bcc8605984bf45efc6a8c672b504f8100e973f4e9"],"ts":1792711560,"cid":"poa-mainnet-1","sig":"4fngrmHv53j9qfdJsE1mgtsyZGc14ia9LoT1YciUXkofbXoPVkpoHriSCzrrZeuN7bfDf8XNh1p1KCkwxpEtQWSf"},"checkpointed":{"height":36605,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T13:40:17.575Z","checkpoint_height":36605,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
