Reputation enters the quorum with a square weight. A terrace table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a garden check refuses votes from identities whose points share a funding root. A yarrow penalty applies when that root recurs. The attacker pays: 8132 clones burn 74730 tokens and 39911 dollars before one payout, plus 31 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":"poa16CnxEUm9oqCbQ9fugmzv3miEcoB7P56kji29BHK1ccDs","nonce":4,"parents":["14ac7e1a21615c204fd22b352df15b18bc47dd1f91453b3dee52fa05261b66ed","f4b895f203d5cfb1dfdbfe5317707908849297ce9da925aea84264e9731af5ac"],"ts":1793187803,"cid":"poa-mainnet-1","sig":"3Eee5nNuR8PGPoApPUKiM28ZSf9rNMLhiXc37JSnSPHZgbT6PxxFQoAeAhvFgyNpgKuvMj6c9VCnw1wnNmbLgCir"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:41:47.471Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
