Reputation enters the quorum with a square weight. A ember table records that split so the chain can see one reputation being divided. Each clone then earns its own points, and a tide check refuses votes from identities whose points share a funding root. A haven penalty applies when that root recurs. The attacker pays: 2280 clones burn 33793 tokens and 57806 dollars before one payout, plus 17 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":"poa187WsoCGNSfWQHf4oZyeb2Ui3KQsqUSZvvucDhAVbMGmb","nonce":4,"parents":["aeb7d30358a21847e6b5acc54ebfae268aeb4fd03dd7dd643dbcb6be34ebf28b","ba4dab1cd7682ee2da2f6ecd490709063897a9da99ac842f9f2156e0a15f8cbf"],"ts":1793187939,"cid":"poa-mainnet-1","sig":"5f2BQGicvUMUqsXorDcKvm1CVHc6x2ALqq8V7MvHm93VKoks2hiu6aLcZTqWgrchBdFeJ9982oKdpMqXxYN7oGTL"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:14:56.852Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
