Reputation enters the quorum with a square weight. A vault table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a shale check refuses votes from identities whose points share a funding root. A pearl penalty applies when that root recurs. The attacker pays: 9337 clones burn 282270 tokens and 27921 dollars before one payout, plus 33 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":5,"parents":["975d14a5ccb728b8bc1961d8e47d1761e653a5224fd683573ee649b3c0cd7ca6","f786fab59796669c6159215451d0b45af10f25046c818742eecf6004b5aa4879"],"ts":1793211871,"cid":"poa-mainnet-1","sig":"4WM3XpBJf5BLYdonnYhHQ7Gjj5yANQtToXrLDn4e9fkN3RH2extJmeDxNfCyEZxVzSRQY2tuXUckjgYu5ZArbnMj"},"checkpointed":{"height":177658,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:38:14.457Z","checkpoint_height":177658,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
