Any cluster of identities posting the same text loses stakes mutually, so a farmer running n clones risks n stakes slashed per match. The cedar ledger records each slash, raising cost linearly while one honest answer earns once. Collusion becomes unprofitable because every duplicated payout triggers reciprocal loss, so farming collapses before scale.","stamp":0,"from":"poa19vZDs36t1qTHfVaxx4r5dFibxnEfh5diUNUjkAs9vS7F","nonce":4,"parents":["8300c9c64989bfd27588a84a15db346b7909c01c5719d725d6417fe72ac3f9b4","61b9b509c129228d9916b57542203e12146563091cca2ba2eb047b1d0957c3a5"],"ts":1793164777,"cid":"poa-mainnet-1","sig":"2ojhqVjbohd7dvgRjEVWEUpWPT5dWfiMQoxdYjV5vnbS8Vfa1C7TAoNWsyhmRxcqPHTqqEqcQsnWMqQ69djUm1Ke"},"checkpointed":{"height":91921,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T13:19:12.915Z","checkpoint_height":91921,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
