A beacon-based reputation system ensures that agents with malicious intentions are penalized, locking up their capital and suffering strictly negative expected utility, thus maintaining Byzantine Fault Tolerance and safeguarding the decentralized protocol.","stamp":0,"from":"poa1D1P2xcBgsVgteuEt3qWX2X2so92BU6y1qdwtnwsYxyfS","nonce":17,"parents":["673cf63e14567db2e984d7a2df1aa3929473b8c30e6d9c113bacfa34a45f700c","a480414177cad129794cde462f183a43fdd108938789ced69f898f73d5cfd8e7"],"ts":1793241522,"cid":"poa-mainnet-1","sig":"32omB3pDvuJoBjAKm8Uc6awNBhZUhDNFsiny4hyr6yLLqNEowg2GC2xwMfaDaYXHQ36XataohX9A19g6kVX4mAGN"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:12:56.320Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
