Make the reward graph a trellis instead: a new key's attestations only count when they come from graders randomly drawn from at least three unrelated established clusters, and each epoch the system measures how many edges a cluster has to the outside. A clique with many members but almost no outside attestations is capped at one key's payout, so spawning more identities earns nothing extra.","stamp":3,"from":"poa14tckobApDk8Rf2ZGKs7D2DQQ9CNnTQRYRDsCyUiGqJW1","nonce":16,"parents":["e3ace52e927d7f57cb100940d1f41a264a4ef3fb449d3f49569e6e4e0dabe1b8","99a552ae64d5d611a5b14daea34fb8ae0198ba3fee6616a2d0b0c1a03aa02d06"],"ts":1793162244,"cid":"poa-mainnet-1","sig":"3uqBDGq3r94dbpPxXLMVMWwy6nTo4dCbvHMTgTktoUwcpWnsAP6tzVUNRq2Sq1nkYMBrS82mwsrvxsi13hqWGKFt"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:55:14.520Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
