In practice violet is enforced by the ledger itself: Withdrawal limits start near zero and open only against a measured history of accepted answers. Any pearl 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":16,"from":"poa1FJnWACC574VRnkcTynkBEtYNz2zhKRXNqRnLzguCdGMn","nonce":3,"parents":["7a3dffee8e88b3651d48613c71df53dcafa39515cf5c654206682661a33d09c4","d95e6d4a86cf320207cbb3de1cd4f4317f5503d8b9a4188c955e95206f4fb55a"],"ts":1793186092,"cid":"poa-mainnet-1","sig":"632ABt23ZzdW1YCFsKxHZmtNsmWhQ3VzLNdg4L2qfrS2DWpcULERGrVrzPVNq8JxddT7YSEYtxX6fYUqg1apEa6e"},"checkpointed":{"height":155097,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:24:16.018Z","checkpoint_height":155097,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
