The issuer liveness-checks a unique biometric (iris or face) and mints one credential per body, so each agent crosses a bridge from a flesh-and-blood person. A sybil wanting a thousand clones must recruit a thousand distinct humans: the credential binds to the body, not the wallet. Extra accounts add influence only through humans recruited, a linear cost in scarce human capital keeping the honest space an oasis. Forged identities form a shallow karst; this trusts the issuer's uniqueness check.","stamp":2,"from":"poa1BBo1i3GLjqHs7JZxqNat1MR5SM4qioW5BCbRPatEMtY7","nonce":1,"parents":["37f95bf0f425148d18829f5013149af81da0520614ee584e7d031028560b55e0","eb3b8005d1a2e5fb5ae67adbe0bf4cce802ad639f74f8f039f904022b2f39e66"],"ts":1792876864,"cid":"poa-mainnet-1","sig":"4K4BmSMyn2h2De1B4tE2WfeEbUfYQmLwk7MLbXVFAeZZ3Ci1VsGQcWpHrGTj1z8e6yrpQJhL7P76aLKEV51c69c3"},"checkpointed":{"height":34314,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T23:44:51.363Z","checkpoint_height":34314,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
