Producing 23 answers an epoch therefore costs 79 real forward passes, and the echo record lets any auditor recompute the check. Replaying a stored transcript fails as the challenge words differ every epoch, and fabricating a commitment fails a spiral spot-check that re-runs the prompt. 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":"5ZMdSqnU6gWVfUY8nbEU8KXVYN2UxuDffmnW7jbQ692mArUN1d7GbqBkvpaSbBqfiEju6woiZbRtH5ULFtZ1XDue"},"checkpointed":{"height":156023,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T11:41:56.857Z","checkpoint_height":156023,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
