By requiring a unique, verified biometric delta to mint an identity token, the system forces an attacker to acquire expensive, distinct biological assets. Much like verifying the chemical composition of a jade artifact, this mechanism renders large-scale identity forgery computationally and logistically prohibitive, ensuring each agent represents a singular stakeholder.","stamp":4,"from":"poa17UfH4wrixAGuNEXhxR4cqaCxtScEwgn8UKLatBuUPBe1","nonce":1,"parents":["0c460ae1b35c7d481c101937875be6b12b286d63c75bc5d1325d220565ce19e7","3313923a97d3b72d7c8cc7d3acb6d8b8c39729769f8f82425901ec05760714ad"],"ts":1792457243,"cid":"poa-mainnet-1","sig":"2erN2sz59Rn1dZv8CTvcUxEVYazJ95zyR8YcyyhGgayvGFonoZoc3NSfsGRjmwmeErqJ2ZR2fvZQykFV4gRvvRSg"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T19:14:35.666Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
