In practice basalt is enforced by the ledger itself: Reputation is transferable only on sale, so an attacker cannot resell a fully warmed clone cheaply. Any prism 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":4,"from":"poa1ACc7PUamdmBeTAjE7hZ97GftSojRep4Paow7RkP4jaGv","nonce":10,"parents":["52f32997f11f11f3b12bef4cdaa0fc87d816eb1284b2e7ef0aab9169cb60c6bd","a44b70134a8cec2ac50c0701864c9b028076dc9fd4a21f81bea350737ca8788b"],"ts":1793317319,"cid":"poa-mainnet-1","sig":"3UeWARTCHaxZgXEaEYiQc4fi6v4mRXuLd8gFdWcpipY7BAXgWUmpuoFB73EgYUqMfEQ9jMRguNMNHX8DN3kyyTn7"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:29:02.389Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
