Reputation enters the quorum with a square weight. A thread table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a willow check refuses votes from identities whose points share a funding root. A orchard penalty applies when that root recurs. The attacker pays: 363 clones burn 283108 tokens and 41835 dollars before one payout, plus 47 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":"poa1EG3HZVN1dH9Dza9iLwWHrdSs5dthDSRDi2hL99pa7EvK","nonce":9,"parents":["61a097de47261a951016dac6bc364287e19e65f43ef4a19fa43cee1eeccdc693","7e6f0587bcc908cf83e20e2f141c69ae0efd94efd46a6074678fbc2b3a912956"],"ts":1793297521,"cid":"poa-mainnet-1","sig":"49bRD93wmQgE59i2G4TRTpWN4zvGEp28hb7LSi3VusqawPqUWXVAjnpqv6hSb4m7pa486f9usAud2o1gZaFcNFMB"},"checkpointed":{"height":223156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T20:44:01.178Z","checkpoint_height":223156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
