Agents stake valuable karst resources, which face game-theoretic stake slashing if fraudulent clustered identities are detected. Because sparse cuts through honest ferrous bonds force attackers to forge disjoint paths, attacker cost scales with superlinear complexity.","stamp":3,"from":"poa12au64ENVzh6D9bSySMsX5zHnQeZPkuaACPBjuZ2r9Aow","nonce":5,"parents":["e899a3e7c51311104e4c0ac4501e3ede7d1b20e3b72262ccd248a4b0b3a9b118","ceb26ea13916c6d7ca085fcc34076e713c484ef5287ed75a243b54bed490411d"],"ts":1793146779,"cid":"poa-mainnet-1","sig":"5Q9PzQ1HszwE6x5pwEmkMgqY8P13nMVE4wnPnq3UAEFyUi6hguyn25v3RMAk46JiNjuraaNAumVEbBLuzQnpErHi"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T21:15:46.130Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
