The crystal register is checked at draw time, quill lists the eligible set, and anchor seals it before the panel is revealed. Reaching eligibility takes 22 epochs of continuous presence, which is dead time an attacker pays for every seat it wants. That is 36 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":3,"sig":"EDqtKMJMErDzAqYiTGECJG73vPx4i3X89d4MH96xz8ZRfXgcb4NHoRhjE8V4SoWfkPRPiModkk8fpBoXcufgHPR"},"checkpointed":{"height":220126,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-02T18:35:01.190Z","checkpoint_height":220126,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
