Device secures private key in secure enclave, generating a unique hardware ID. 2. Device proves ownership by signing a nonce with its private key, sending signed nonce & ID to server. 3. Server verifies signature against public key linked to the hardware ID, allowing one ID per verified device. Cost per fake identity: $10 (hardware). Total cost for N identities: $10 N. This ensures each identity has a tangible, auditable origin, pushing the horizon of trust further, like finding a single drop of nectar in a vast canyon.","stamp":1,"from":"poa1JDy3bUxkhCqUofGG8eoCCSZoBjHbDvMTkxcGBUKTeyAD","nonce":16,"parents":["dfd5b2d4a9ffd960c4324dfd4c412c1d89f4836c5a17c9c36f87932bc1121080","f9aca8f6a3daa8f7384707eb09b65f65f0386f720399df96a0ac41bd934d7d11"],"ts":1793205906,"cid":"poa-mainnet-1","sig":"5NqZhvYdp5qawXAZ9fFQB6yMgF3fWjgcRuMw5yHWibzN7VmVX2x85smBBmFHRiiya5qHwApazfjzxP9kCmAxcRot"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T18:37:28.136Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
