Reputation enters the quorum with a square weight. A karst 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 beacon penalty applies when that root recurs. The attacker pays: 5915 clones burn 25105 tokens and 22840 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":4,"from":"poa187WsoCGNSfWQHf4oZyeb2Ui3KQsqUSZvvucDhAVbMGmb","nonce":10,"parents":["b608609b6b86555c7b01d6fd27ebd3a10e6d1f4516be08886fe7eed1f2a7bd93","a1abee8ff95533a0c97c60390aebb4840946a419d47f63d6f83887dc6bfc115b"],"ts":1793320685,"cid":"poa-mainnet-1","sig":"4xAB6tp9vKH8ss65xsoqTizBQYGyBqT5VHvHtB1UBGSSxK4nnATvZwoYb4f4nFjEjq5CRD2aLR87SStM24U8X84d"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:08:15.796Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
