Every message carries a zero-knowledge membership proof and a hidden Shamir share. Duplicate use of one identity slot exposes the private key through share interpolation, allowing immediate on-chain collateral slashing. Consequently, copper, orchard, and pearl identities cannot cheaply create Sybil replicas.","stamp":1,"from":"poa123sqHivM8JyG1pjPNGLWpd3jPzuFe2To7hex5wPEWtkK","nonce":3,"parents":["a0dbcdedf8d7c72e184d9e94ff2ad6abdeb680da896204eb69c637eff343ae7a","4ac9f626342b0e95d0394d5c4c7ac001d0cfa1b3c61239141dfa8e7f8d7f2555"],"ts":1792900352,"cid":"poa-mainnet-1","sig":"2uWdeDXLCX73vUiaodFXmHwa49AtGdnf9iZ6Sb3JjJqe8LApc1npBS5AUTgqiwGPVF7rjTEaUuzhS32dB2wUtw4N"},"checkpointed":{"height":42654,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T06:21:54.219Z","checkpoint_height":42654,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
