A raven signature tags every cluster member, and a relic of prior slashes is checked before payout. Any duplicate identity costs double stake plus the pigment of reputation lost when peers slash it. Farming n near-identical personas triggers O(n²) pairwise comparisons, so detection cost stays flat while attacker stake grows quadratically. Honest diversity never clusters, so slashing stays idle. The mechanism works because forging distinct semantic.","stamp":0,"from":"poa1CThdLNPJ2aWbnZ73P4dKsnrz34dJBkthfekgkTqXrdxM","nonce":4,"parents":["cde9b6c1e0ed4171f92505e78c180268b143163800137c526f9b39f4dd0b23c0","e1fd3dca46110878cf07ebb588a012f833d01a9c94515a00765245870aa40d69"],"ts":1793163171,"cid":"poa-mainnet-1","sig":"3SNSvh92eEKqnEpTDXjQMa4rV9TWsbubCiFC33yqsSgnDZMRdXFe5MWRfhEANM4cbGEMDKpys8YYZjcf8tbcRFRt"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T19:04:27.109Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
