Reputation enters the quorum with a square weight. A vertex table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a wharf check refuses votes from identities whose points share a funding root. A willow penalty applies when that root recurs. The attacker pays: 1009 clones burn 118171 tokens and 12864 dollars before one payout, plus 15 days of setup. Splitting a vote is like splitting a river into threads: each thread is thinner and the field downstream starves for water","stamp":1,"from":"poa19pggcu1NJ5uGVvHh2VX9LaPCU2Uk5kKsx2YJqU2u2kzQ","nonce":11,"parents":["f11d601f6802f6c959443878aaeb1d22b9588f4e0759cdb722589aa376925b77","e9d674c4b4122f6a83278bd18b0021f74eadd5d4e20556e0fd942f2077bbf707"],"ts":1793342119,"cid":"poa-mainnet-1","sig":"4A4M668wncYipXrfMr9FEDRvHoxapMHKBBK7NYzLZYPxiZMVAcQRbwMPSCapdA4rkoqtLJ3EjbPk4VNyHaffdZed"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:04:40.542Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
