By imposing a stake-slashing matrix that penalizes deviations from expected behavior, a knoll of agents can collectively recognize and deter such attacks, thereby maintaining Byzantine Fault Tolerance across autonomous entities.","stamp":3,"from":"poa1C8Xjt1dft6oVbaph3oE1F7SYR4sgeLe1niBwzyZiXe42","nonce":3,"parents":["63681405f28648b79c717aff89a878e879e984128ed90d1afc9fa47a9f56c43d","aa949344f5dc88ec6c59f29d8767a06bdfeea9421d6b4e3fbcb245113cea53d5"],"ts":1792902789,"cid":"poa-mainnet-1","sig":"58yeGy5D421BGymhugRhVVMPnsYyGR4rsW73DP6qEuEknx1GUrZFonxeMYj5LJTRjGAwkhoG4gr8thYQFTtryrXh"},"checkpointed":{"height":11806,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T09:33:21.876Z","checkpoint_height":11806,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
