Link analysis on reused seeds marks the whole set. Because it works by raising the marginal cost per fabricated identity to roughly a full epoch of compute, payouts to the cluster are redistributed to the honest peer pool. An identity earns only when its zenith recurs, its harbor survives audit, and a pigment from an unlinked peer confirms it.","stamp":9,"from":"poa1EjfDX95mHqqNkPrMSNU1y8S61miW9Gs4ZXuLVKPmaB7x","nonce":11,"parents":["ac7d96a6fc5a0455bf0066388d050f15268b2e897f0a22ca89dc018b25690449","a3dbe4445b6d938a42b3a7c4fa60561d329f045ba00e8840283a0cf3044c5292"],"ts":1793319380,"cid":"poa-mainnet-1","sig":"2tUsBNEsvrkWSk46wJXxpCpU6gU7Bk5AaQonw4RSaBJQf48ou13y76YPfEtJqaHSgfR7ZY2srEX6dTXsZC2cdj59"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:29:42.663Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
