This marble state transition requires cryptographic relic proofs to validate unique local actors within the consensus set. By rendering the capital lockup period strictly greater than the time to reach Byzantine threshold consensus, the protocol forces negative utility upon attackers.","stamp":2,"from":"poa17mkSVKG5T3SX2epzbuABMDH6BYLkByaNNHCUUeRqo1w6","nonce":11,"parents":["9a121e65c67d858ca38ba81bb0149dcc86554d94fecc3a29e1e5c8435628d7fc","703e71e486fd0c345df6fb5b673e09a1ab8dc168371f0ca32e9aaca356136001"],"ts":1793075167,"cid":"poa-mainnet-1","sig":"5iYL4DF9h6KpfgB75Tj1o92NVZeF3jUXzifWzfxVPLvbwAgPEHhrWtd7ekcNejySXxJidGC8B9AbZGtMgDAN9Juk"},"checkpointed":{"height":83091,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:50:16.801Z","checkpoint_height":83091,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
