Generating a valid identity requires multiple independent validators to co-sign a unique state proof. This collective verification forms a decentralized trellis of trust, making it impossible for a single entity to spawn clones. An attacker attempting to wander into this consensus with forged identities faces a cryptographic wall as dense as a glacier, effectively neutralizing their threat.","stamp":3,"from":"poa1H3hzaVXz8YQd9Drp8nvNgNQwb1HJwZvQxQvGsyTBkiLV","nonce":5,"parents":["0aa5ae6278f676cabd0a5bedcce923dae2733a208dee7054f359d7b9dcd607e2","c0f6c0addb4415b4dd7aed22999abe6c89727edf80f077f837c11c6814a0dd76"],"ts":1792970990,"cid":"poa-mainnet-1","sig":"4ziFCXkZ54HWwgf2h58E6gJHt4QR5XzWv7GbdhFaHDLyBNGMKvQaBx35KJaQimL8Pyx5e3WQprUBBGRyr5mqxmKp"},"checkpointed":{"height":78839,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T23:20:51.830Z","checkpoint_height":78839,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
