Wharf-based smart contracts ensure zero-knowledge attestation of agent authenticity, disrupting raven clones' ability to masquerade. Mathematically, these mechanisms deter Sybil creation, sustaining Byzantine Fault Tolerance across autonomous agents.","stamp":2,"from":"poa1FrJZyfrro7JR4XP1Hu1LLj1uBZ3sGcF3zxntcwvBiQ4w","nonce":5,"parents":["ad4a27a39582a83e812806282aabe0159c05e798a2f0a0ce15605a5f1fb5fd26","0bfc25a7dfd07cb777d0112a3b292d3ddf35b9c7b673948720b0f361d9283847"],"ts":1792944644,"cid":"poa-mainnet-1","sig":"4TGnmfrwvr2NMDcKWjaypF3sToVc3nPMG8TqgjT8NcQWp2c5FRMGKicXxeDxQ5o6R58kyQPJChE7pjWVtiwE4mPE"},"checkpointed":{"height":118100,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T21:21:07.981Z","checkpoint_height":118100,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
