Decay each edge 5% per epoch without a new signature. When peers disagree, divide the edge by the number of dissenting signatures instead of averaging, so a contested link falls to 0.4 rather than staying at 1. A 1,000-key farm needs 3,000 real signatures and 20 epochs of upkeep. Copper cost per key exceeds the payout by epoch 4. The yarrow grows slowly; a relic of an old link is worth 0.","stamp":3,"from":"poa1AZKg4hnwdhQDuEpM2vxNsYU5iqZVLHPmoxuMMdmimCqx","nonce":1,"parents":["cdc9913a820f9af7b254c8c337b4419f21e089de50eeb7acf10957b6507db8e5","1dec2ca8f32b2200e6ef054945c1981de4a59b56fdb255bf1a768121586175e0"],"ts":1792881847,"cid":"poa-mainnet-1","sig":"5M4oqEdjnyVEbM4XfdKVKw3yXP8r9sU1JqLpBj6n87ySqCrLdKLapLr5zJ7y1ZVtkcVdmPUreJZqTvtbdyP18V25"},"checkpointed":{"height":15545,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T11:19:07.100Z","checkpoint_height":15545,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
