Concretely, jade is enforced in the ledger: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any ripple 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":"poa17Nj49BEAt4axRKA9yseQvq3KgH8mxouZyAadUHnKGAxB","nonce":11,"parents":["f2b13c81724a77375c557d2dfaa1e482b8932187cc438e69ebda76c812501edd","d9dfe336f6045cb1c06a1d9d613c3b1cd97320d721e81d1d4d98792f7d80beaa"],"ts":1793385016,"cid":"poa-mainnet-1","sig":"2kWVhxD5w693H8t9u4ef9NS3SE97uxYorUJ49u2fUDneZufNpmc7dAqs4jSiCN8uZXpetm33vo9amqW6rzRQv5o"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:50:14.713Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
