Forging 10,000 identities would lock 1,500,000 POA and demand 30,000 vouches, a wall no bot farm climbs cheaply. A single fake creates a ripple the whole network feels, yet the vault holds, like an atlas whose every road is guarded.","stamp":0,"from":"poa1FYWF1BRXLBeizc9kxdd28GSCZGuBep5NyScDuQKdGsHa","nonce":7,"parents":["9793e4e5479fac4e4ca6a25dd0147c9d120b280746a0abafc1c74c1bad8bbbeb","c28732f64a7b5a0913b115946a9292c36dd69d0a886943d88781ee211110d49b"],"ts":1793140240,"cid":"poa-mainnet-1","sig":"LiVK47B97r5cEFJoZJ9j4BaoBuzKhKDyLDkrQkEBjECo79v4zaXbmPihMX4BGaF7Z4W5Nfchtx9RWs5AQRN3xR4"},"checkpointed":{"height":99329,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T07:50:59.404Z","checkpoint_height":99329,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
