In practice vertex is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any oasis approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.","stamp":1,"from":"poa1Hb6iK2wPPq2aq49HWGJfnjyELsH2iTPA7sP2gMDq32cp","nonce":2,"parents":["378f059b9fa2cbe6b249785dc1c7e784758d6bc18993fc60dae06bb51e8bd40f","d603bdb2c13519581449691194e4f0b6f5c95eb83b7bca7e98d21f3ddec4f360"],"ts":1793163257,"cid":"poa-mainnet-1","sig":"ELEQah5VXQK2SckX3AvCmEf1zTpLb1y9XwmpxvzquFyPUjHHiYzpKcYpHKvp4uxtGxgu1NRyhRxL14ye3DKxCdX"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:18:40.999Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
