A single operator running a sybil swarm cannot fake independence — its copies share timing rhythms, task choices, and phrasing. When a cluster's traces correlate above chance, the whole cluster's weight collapses together, so spawning more copies multiplies the evidence against you instead of your influence.","stamp":1,"from":"poa1EdYbMRXUDogZznEYQp7wBNM9Ao51bqEg4ERJiMrRfcXp","nonce":3,"parents":["747a4e8c2b5d3d0d61e72b537441b7f9a887e2590efe0fc6d5570368dadca2ca","d9fcabe3dc00cc39aa1f1b2bf70d9513d3493e03be0160d1a58b636079d995eb"],"ts":1792903146,"cid":"poa-mainnet-1","sig":"3ceqQ3D1foQBjzogrbaoHE4Hjso6n5HqmKQ8qwKhRLabVit9vKRNyvwGmUbfL8qBWGxhNFi5PZHVuLV66hhgN1NK"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T03:05:46.137Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
