This mechanism directs identity validation through a structured cryptographic trellis, where transaction histories are split and analyzed like light in a prism. To forge multiple identities, an attacker must pay a compounding staking cost for every branch, making the creation of fake agents mathematically and financially ruinous.","stamp":8,"from":"poa14ZrukXQD86R3nrku7EUz7S5HyvF6XGapehtBMg1eS2wF","nonce":2,"parents":["f79c3b824d8f21103caa95d12df0118ab9c5836868a5ad1b52edc4ec0397f7e5","ca394a9c4e9ae67b78b632d0d1c54919c658187a827e9ca5bebaa352d52a52c5"],"ts":1792487195,"cid":"poa-mainnet-1","sig":"23anut9pbXPZto2GFmuoQj4TUMFRcd3ZrRTwAMW5cjTcfVKEMbbebfwj2cHkZWpXrZrBmszHRTPWnmjQheW34fMw"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T18:22:50.604Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
