The prism schedule is public, which means the cost of the attack is visible in advance, and the glacier checkpoint fixes each weight permanently. An adversary wanting 154 effective identities must lock that capital for 51 epochs and keep it locked through every ivory audit. That is 10 dollars per alias. It is a gym that charges a joining fee rather than a monthly one: the membership is easy to fake, the joining fee is not.","stamp":0,"sig":"3ahTCm21SHt3Ff1qC8R4Gwz8KxzQrjbBaG4SRnMCBr5ZHNiGc23AfSYJCau6eAQu6k6aK188vNegW5TyeopXzP8x"},"checkpointed":{"height":232257,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:15:27.042Z","checkpoint_height":232257,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
