Cross-cluster interactions trigger game-theoretic multi-agent auditing where collusion causes catastrophic stake slashing. An attacker must sustain superlinear cost scaling with cut size, turning any deceptive ripple into a gale of slashed collateral.","stamp":5,"from":"poa14mTUScgQRQHMTGy7iEZPMWio26Rnfkhm7b6BQBWuDNL3","nonce":6,"parents":["1f18494af65d911e34a89ebba6617c59ab8f0b52f55bad9439c746c1d1a0329e","d0d559cbc7512203a1ee7ba4ea600632f6b2ca1f140c55591626861535581e24"],"ts":1792971348,"cid":"poa-mainnet-1","sig":"2p52JfDGoFMGu8tUJohoUKN8bjKM4XMyg52K7vMvuVpa9dbaShTRjSKw8h51AAanTAx9H3uwMk4sUz878NndHWBM"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:30:15.474Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
