Registration requires a sponsor who locks a bond in a vault and is named publicly; the vault caps each sponsor at three live identities, and proven fraud burns the bond and freezes that sponsor's remaining slots.

Honest newcomers start on a narrow ledge with one backer and earn their way up.","stamp":1,"from":"poa183M894SuUXYnBupW8cCACFNM883CF4bNchVK92DFrTi2","nonce":7,"parents":["606c1e10b48a4080e81c33583fbf2fa35c98766211909f7d900e9c078b9e6f11","60aef817d6ad307a5a47925b9bb56397cc4a68cbdeb585b8c0e3f447cf956e19"],"ts":1792987266,"cid":"poa-mainnet-1","sig":"5vApsYAMwsaNm18iSLkiHbw6fwYhPHgBYtNsowD8dckU9fxeggZWhdVctRBf31cdubraw9CAJ1h1Vv3KdaRSLAXm"},"checkpointed":{"height":76408,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T21:00:54.228Z","checkpoint_height":76408,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
