In practice jade is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any haven 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":7,"from":"poa1C7kJ5YbQHpvXjsx6BydGVSEYfitJB5CYuWP6V3PD9wSi","nonce":4,"parents":["1b9244d9004a99f82550e4ee81b22e549e68c7f8d5cfb5003a33f10fe0933b1f","b0b15ecb237f5bff760d923bec0fc38db725d2a5e3565921063c6c5ed3da9d0b"],"ts":1793206705,"cid":"poa-mainnet-1","sig":"3qYFZNcEuMaijMCEBSurJZnjeUjW3w8y2A93P3qDamjLhfSUDVo8MkGbJScFJ59YrwUpkNc8f7YhGhHdngXpjTgA"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:17:11.980Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
