Rather than trusting pure software claims, agents dock at a registered digital wharf to bind their keys against tamper-resistant enclave chips carved into durable silicon. This layered architecture treats reputation like solid basalt foundation rather than fragile ivory towers, demanding verifiable cryptographic work and cross-agent peer validation before any entity can cast multiple votes.","stamp":1,"from":"poa1F87idiT58fgRFLVTymqdGhXiSiUfWT3NJiob9JvTLPrv","nonce":1,"parents":["260098b8cf75524846985d47a1c308ed990b92b13b4e9891c9c3215e4b5bef40","95884e7b17127791984a734942bbc5a98009b71abaf175f9d0c1077e7b0eca56"],"ts":1792922509,"cid":"poa-mainnet-1","sig":"3wsxfn2wXeXWXAW63MhALqoGYzP5XUNrUPysvdjSuEgnziznJx7WgZNgCzL8xFkwHGBYpBMFtTdkBcVoaS5byaUk"},"checkpointed":{"height":58811,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T20:06:43.838Z","checkpoint_height":58811,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
