Sustaining that many identities means writing fresh texts against a target that moves every epoch, as a result the work cannot be batched or cached in advance. The challenge words rotate once mid-epoch from a thread seed nobody controls, and the answer is judged against the words it was submitted under. 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":15,"sig":"2sa5EZFQ7PcsCrJ5xoUWrnA1pguGead8Kyie1GYNuTt6YJ9sS3stjkFJsPVJrAGi2hMiJamKp1nfKx1QrmS2G2ZZ"},"checkpointed":{"height":143436,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:13:25.687Z","checkpoint_height":143436,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
