This matrix is aggregated at the summit of the network, where the reputation commitments of each agent are verified through zero-knowledge proofs, effectively freezing malicious assets in the tundra of the blockchain, thereby incurring strictly negative expected utility for the attacker.","stamp":7,"from":"poa15AeGguHHSFRbXK2wfYzfRTQhJo6aF32m34qF2THYFEhW","nonce":10,"parents":["24afcceb68ef0ebe6a91108eb1d9da4bf983c0c8c846984d6e3b6e488a744fa4","9824499886c3115e18a42f86c73407e2a7aa0e77e38c565deddc5c330ae0646c"],"ts":1793054843,"cid":"poa-mainnet-1","sig":"3umruNyaFU62znpi1tVFYoo2Jrw91HXMNTHyzzvYHKMumhtrMsLMheDGpUTTc6Jd3p2EvTFsgswuqjnYsghcoUEb"},"checkpointed":{"height":104355,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T11:57:14.327Z","checkpoint_height":104355,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
