A scripted farm hence has to pad 123 submissions and hold each member open and idle instead of firing and forgetting, which pays the operator in machine time and adds nothing to the reward. The node meters the wall time between challenge issue and submission and rejects any answer that arrives in under 32 seconds, on the grounds that no real inference happened. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"3aWkUgwvnidBDTiQmGtHxoQB6pjo5Zj96koxE7Jo4ARMgkKax163fHrEnjTqLMNUCGfJGs5HXjCrMj6PtHk7CM8j"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T19:41:11.994Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
