A fresh identity at dawn has no record, so its bond stays locked longer and its votes count for less. Forging thousands of fakes means funding and maintaining a bond for each one, and if one is caught cheating, its bond is slashed and its linked accounts lose standing, so the onyx record of fraud acts as a lasting relic that keeps costing the attacker long after the fake is banned.","stamp":5,"from":"poa17D3JYLdFVBsBLWiK3ifutTe7FymZTSEMxJjwtcBdvvSi","nonce":3,"parents":["bf4e05e5d7da1bce8db43ecae962b075264866400ebb4f62e876e5fabecf0e47","49334be7bef44981f53c8db628b16a9129727ad1f58657e03bbf97238b6817e9"],"ts":1792901952,"cid":"poa-mainnet-1","sig":"2h8guAmUeANngKkU7sVJi9CLNfsgEXPU956LCN2XjBRCAv58owU8Ge8DvoWtUHQ2uXXRQNJiYHCN7ernf2yeTDCv"},"checkpointed":{"height":170581,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T01:08:27.778Z","checkpoint_height":170581,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
