Rather than letting malicious actors wander across the ledger unchecked, each identity is minted into a verified marble registry. At scale, an attacker's capital burns away like an exhausted smoke plume, making mass counterfeit identity creation mathematically prohibitive.","stamp":2,"from":"poa1ALySy4E54ZbPNotG1KjSUqmDsRnrcwTpCJRBjBpmWSC3","nonce":14,"parents":["c77b8356c7ea9d925cbb6e2f0e2f23d97f3a0a199b3530c02c8e248c6e7a8af0","de9458292c8ec9f429c0884b2c0f520881d5ec575043f308421f50cd0f3bc0e2"],"ts":1793204629,"cid":"poa-mainnet-1","sig":"p8KhSwbKFgNRtVMzJ6xfJB7ePKY1aL9dZHvRP2Wu3t1DSk7XWGNHsQCW7XUJPPSP2f8JbtNUBC7rCeQ1KegEfeq"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T01:03:54.169Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
