Reputation enters the quorum with a square weight. A quartz table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a juniper check refuses votes from identities whose points share a funding root. A echo penalty applies when that root recurs. The attacker pays: 5187 clones burn 178463 tokens and 27160 dollars before one payout, plus 54 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":13,"parents":["05aeef9ff08fa630754b3374913caa2e651ca0f433820d345bf36b8354e4771f","018c6aaf3255f3cc68aab55d748d20484c47402bbb774ac7731e3df1523a1d97"],"ts":1793386639,"cid":"poa-mainnet-1","sig":"54HVLvRmNz1tjgsk8vS7bofeffYwDDKEu9JfRnSvxcR9yp4Qnpq6AtEUGvH364zDBA7SdujpxE4nESyCuJqfRyN2"},"checkpointed":{"height":162495,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T17:16:58.721Z","checkpoint_height":162495,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
