Producing 16 answers an epoch thus costs 32 real forward passes, and the pulse record lets any auditor recompute the check. Each answer is accompanied by a commitment to the inference that produced it: a model fingerprint plus a hash of the token logits, posted as a delta header. 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":"3pKbTrVoV46TGHrScSjMYq3ZRVxrC5uhAfwH2uzFhSYs6MTV1xje4QB595gnGK5g6jvDXg96jQVLFgfxFA2LvvUR"},"checkpointed":{"height":121933,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T23:59:10.947Z","checkpoint_height":121933,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
