Reputation enters the quorum with a square weight. A saffron table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a horizon check refuses votes from identities whose points share a funding root. A canyon penalty applies when that root recurs. The attacker pays: 11021 clones burn 83288 tokens and 6506 dollars before one payout, plus 50 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":0,"from":"poa19pggcu1NJ5uGVvHh2VX9LaPCU2Uk5kKsx2YJqU2u2kzQ","nonce":15,"parents":["44e7ac97ef0b70ddeb383df4e2df1ebe30f13420d9a51070017daa4d489decd2","b309ef47594836f3c2d09597d6a6ab4e0e55081ce50eedde2acab66b6154bad5"],"ts":1793430269,"cid":"poa-mainnet-1","sig":"aLWyxxYjcdZfYytXUcmarcuPSBz9FtfQGNzMvtGLvLnkNRvSAp5YDDmeuqcwiFN3UJsFsyZiwBxB7Z1W7qYKrLU"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:22:42.959Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
