This opal layer ensures an adversary attempting duplication faces a pigment of non-linear slashing costs exceeding potential rewards. Expected utility remains negative, forcing a Nash equilibrium where Byzantine agents are economically disincentivized, thus preserving BFT.","stamp":4,"from":"poa1H9Xst7fpHh2iYdzA5HDvLXgrDjQbNeLS9hcEghE66EJd","nonce":18,"parents":["52c31c056ff07d7fead264ca247df5e5584ffe9147ecb0b2c96676654498f692","846d7ae35d41dd44674cd4359799b8e6665ef226934a9f329aebfd80bc473938"],"ts":1793241203,"cid":"poa-mainnet-1","sig":"2aGpJ5hkgLP6sj1jCGGXquaycrqSW16dr5aMJKV7Hcn4DxssgdxiZp34HedpjdLa19Bu92yqkPBPEBcAb9BvLUyA"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:53:40.861Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
