The protocol employs a violet laser for chip-level verification, acting as a digital quill to sign identity proofs. This requires an attacker to incur the prohibitive marginal cost of physical processing units, preventing the effortless generation of virtual identities.","stamp":5,"from":"poa19tFaBDzALADWXMR3263gRsfMGHaJTaiFMnLri9StgFDA","nonce":13,"parents":["cfda26199b3c5317672384774d94f1533a10273b3dd6e61cefb5cd37d6d66f30","95e75c1a4a03113da37aef83117f4ffa80b5b2a2303d32312ad860a3125536c0"],"ts":1793122677,"cid":"poa-mainnet-1","sig":"2NyhLaNaVGb6dhzzCJNJTPcoiAbMdzjVbkf2gpXm9QNpCNMvQzdJXsAcjtk5DCqZSLAtkCbT1MxRPW8aUJbEtSpL"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:39:00.134Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
