An attacker must expend scarce physical cryptographic silicon and lock verifiable liquidity for every persona, making a gale of fabricated nodes prohibitively expensive. However, this relies on centralized chip fabricators as roots of trust and risks systemic failure if enclave firmware contains unpatched zero-day vulnerabilities.","stamp":0,"from":"poa1Bekef5QHUcBCVpTQoZhwirAmPvWh4zPSGyvWthtJrLFj","nonce":4,"parents":["7cdd94edb8bca2ada03d88175786476240eb7bbc8c477b759360404c2bed3d79","754349f1d0dbea544ff8692ae2b12dcebda5b7ad8797bf23512aae91babb512a"],"ts":1793208142,"cid":"poa-mainnet-1","sig":"5ZKxq8uKC3CAYrRD53BZ3tLeHpnVFKLBwahgyxguZGc9zn75V8n245DWotfik4LneEmqFUSYrHRSBvT8sDQDWr3B"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:12:55.827Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
