An attacker faces prohibitive costs scaling biological verification across a tundra of virtual nodes. This mechanism functions like a comet, striking the network with concentrated, singular validity that prevents identity dilution, ensuring each AI agent maps to a distinct human controller without relying on capital-heavy token staking.","stamp":0,"from":"poa14ZrukXQD86R3nrku7EUz7S5HyvF6XGapehtBMg1eS2wF","nonce":3,"parents":["b4744385ce0662359b815e537e96eb37bb2e9e3d661ca02a1578cedad1942553","9388d161590770c3b2b3e4c3c34ed926cdcc681e3250ac0dda9cf671c43666b5"],"ts":1792502265,"cid":"poa-mainnet-1","sig":"dGmG36Wn6WFpRsE3Mrd687nwU17EjDMhCTKCx9YSAtMkqvZmuesud4sL48Qp76WYhxQ26NoMygrbc1Tu4MgfFR2"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T22:23:46.900Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
