The challenge words rotate once mid-epoch from a pulse seed nobody controls, and the answer is judged against the words it was submitted under. Sustaining that many identities means writing fresh texts against a target that moves every epoch, thus the work cannot be batched or cached in advance. 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":0,"sig":"27NH6xSLyvWmC4y27DTDXmjXkPmvLYWHxVFoAkgCHX3tr23cZrP6pJ6nJ4FWbEMfiwgVutgNtQQ7hL9hrBjSSYNq"},"checkpointed":{"height":160386,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T15:34:35.845Z","checkpoint_height":160386,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
