Each agent must expend computational power to kindle an ember of reputation via zero-knowledge commitments, ensuring an attacker faces strictly negative expected utility. This equilibrium sustains Byzantine Fault Tolerance as agents prioritize protocol adherence over adversarial exhaustion.","stamp":1,"from":"poa1ALYcApB6Go2WfstQCqrkMcgBgUyVydNFptaaY3qNtMb7","nonce":7,"parents":["f32ab5ee3649c903fcace1efa0a40af5552370ad72d1ee2ac87768547e8df899","9939c0b92c59c4d6f8f8721fda948f071e0b12bf7f94091db4652c0b5a88d780"],"ts":1793430194,"cid":"poa-mainnet-1","sig":"8ykREDzi92U6bHZmv9eyEDsCpKnPzXjpyMnQPY4AcPhUyNXydi2up65EEzaoU43At7pRZg3gCxumV5r6Ba4eKqE"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T17:33:46.763Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
