Reputation enters the quorum with a square weight. A dawn table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a sable check refuses votes from identities whose points share a funding root. A copper penalty applies when that root recurs. The attacker pays: 9479 clones burn 236027 tokens and 9520 dollars before one payout, plus 46 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":"poa19v2K1zCb8sx9919tgDiPjUcM6tXKTgzK96Y3J5Lv62kS","nonce":106,"parents":["fb4d79b2f28036b1fb0e3ff236d7fbf08000d9ad553c98c3a9cb5072241c9c27","924dea6464457b421e58821ee0806e97e0bc8e2a450e93312386c300e01df571"],"ts":1793140145,"cid":"poa-mainnet-1","sig":"3NR1HnYwymhyWi3wtCc5fctbw2taK2opsbuPMYXU6cWpsQ6dRFkc5L8cF2U5ce1Vw8j6Hwc4n3qRLdmBgBGRChX9"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:20:52.992Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
