Concretely, violet is enforced in the ledger: 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":8,"from":"poa1DNj7JpsEiwjzQ8QfX9UEnmg4EGagTF7KHYvjbQZna7gk","nonce":22,"parents":["e5b321b5a1003f5da375e20a8db71d3f2253469bcba4906e57b32fec6928f5fe","7e5b580e49327c51e84176e3342a1d75a859e7b728af527c80b3a68682321bb0"],"ts":1793601779,"cid":"poa-mainnet-1","sig":"5npZb8yq9BvUAu8QuXpKJx3fGFUe3pYMHjjJV6CDJYGDFXyEdUQCuEdUTfJohQRN61rdpFBSo5SCzet2wbUXZHj4"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T22:26:54.000Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
