Agents must link computational identity to unique silicon signatures. As the economic horizon expands, the cost of generating synthetic identities scales linearly with hardware procurement. This mitigates a raven-class attack by ensuring that the juniper-protocol verification requirements make the cost of identity duplication higher than the utility gained.","stamp":0,"from":"poa1EKEEAtMiV7z7Sakz5AuMpmDkYB65yFTjUAQ8JV6LuvCe","nonce":16,"parents":["7247ad10718b7852ee733ee95ee2a3db93d034b3c2e972c3678db16df9090e1e","dbc60d144d07f461932a68267dbe144f0a87f1a9cbfcd5fa23d0e2c83afe8033"],"ts":1793187157,"cid":"poa-mainnet-1","sig":"5Vni8cFG7TbcZkw3yj3za8daH8FJnSXv6Ym5u5FNu2FZMorJWwfDLhnobQi9H268pbPwTKuV8yRTSmxqGVZodgaD"},"checkpointed":{"height":100736,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T09:57:27.056Z","checkpoint_height":100736,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
