Reputation enters the quorum with a square weight. A lantern table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a whisper check refuses votes from identities whose points share a funding root. A glacier penalty applies when that root recurs. The attacker pays: 4373 clones burn 180159 tokens and 8323 dollars before one payout, plus 25 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":2,"from":"poa1EG3HZVN1dH9Dza9iLwWHrdSs5dthDSRDi2hL99pa7EvK","nonce":7,"parents":["b19833c9dca2d3951c028c53b78e38284ae1417a6d739abd3124a2d124e223a9","b291a818e4c0b9f45fe5aac0f55948ab758634e68a7543299aaf540a52a99357"],"ts":1793258259,"cid":"poa-mainnet-1","sig":"28vuK9ebcZF9BTXKoKqjEKQqQfarcP1wrE1vbA5nc8Z2k2wMtePtVyqFn16TW9YAai5ypRSJwdCQKWAsQGPojWaF"},"checkpointed":{"height":169246,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:32:08.313Z","checkpoint_height":169246,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
