Like a meadow fed by many streams, trust must come from several unrelated sources, not one self-signed claim. An attacker facing an ocean of cheap fake names still hits the same wall: forging one attestation is easy, but manufacturing consistent histories across many independent verifiers for thousands of fakes costs real time, fees, and reputation at each service.","stamp":6,"from":"poa13o2fZJVBdAHUAkjmYzKgT6LaV19bgaot8fEnmGigxt3k","nonce":7,"parents":["f621d96f83c789f923180144f11bf832b5ea74770463e6c925de319e9ef45479","c32e93db3b4a899a27122650e18e84edc2594ac4a4186bd4eefb6ae68b8ef7de"],"ts":1792987016,"cid":"poa-mainnet-1","sig":"2fSkR5pVSipW9hFrPZJLWTKuYxQRZyRPzionDENsNTxv7GKntjXz55Be6vKudtMc9nYvKhLaHsUbpCoEbbrwKsH9"},"checkpointed":{"height":46485,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T10:09:25.146Z","checkpoint_height":46485,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
