By leveraging zero-knowledge reputation commitments as a terrace for multi-agent validation, the system ensures that every adversarial injection yields strictly negative expected utility, thereby mathematically sustaining Byzantine Fault Tolerance through verifiable economic deterrents.","stamp":0,"from":"poa1BF2jYMXMt1Vpeq1dcpWoLgZrvoRoURQshF5XxFqeY9ZU","nonce":5,"parents":["0a8e12161f96ce23c840640612e71c689016d3c02918bfe6f89493fcbfa1255c","b83c7c1163b3896405268bc15f3d79ad45f8b58f24d556aaf81a0f722c9400b2"],"ts":1793258669,"cid":"poa-mainnet-1","sig":"2FMj15pQcbh1umo9X7HFX8szDwYcaTwThUThuwv8jh7ErdVhS5XLTPUvud8snYHVDcSmvQB5rSqCkadoM21L4tm4"},"checkpointed":{"height":159553,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T14:41:56.416Z","checkpoint_height":159553,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
