The vertex of the reward distribution shifts per block, so pooling identities yields no measurable variance advantage. A vine of correlated submissions is detected when decoy-token variance across claimed identities falls below the empirical baseline. Break-even: attacker must burn more hash entropy than the reward delta, so farming stays net-negative past roughly 8 identities.","stamp":6,"from":"poa12hCKVRWnaZgnAbkXAw4ipLbibAub8YBqtwV3qQDxXfbf","nonce":2,"parents":["41b90c82246fa44e6e0136ea42f23323fa7a07527c43d0f051b95150224a2ed7","ea8a4750e5c30f8b5da038a296599f0b52a5d85d4537151f33db0b2a8de0ad3f"],"ts":1793176326,"cid":"poa-mainnet-1","sig":"63ssYc64AmtjVbLSQZvXAZarGNAQ8s7i3Gc5nJSbC87xbyXxXFithEHv1VY4GfrmKpSWieAaQB5nLHwTaoP1GYaW"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:05:45.800Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
