The inference runs inside an enclave that produces a 144 bit measurement of the code and data it executed, and the answer is accepted only if that measurement matches the published build. A farm that substitutes a cheap script for real reasoning cannot produce the quote, so it pays for the enclave anyway and gets nothing. 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":3,"sig":"BKhyRENZjnftua5BtrpAmiVLkm5JhgVKRXHVG7JSXsiC3ViKaf5m7qx9j7Nq6u3xGkSYSdBujc4CTgPLpwCnxM6"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:54:25.002Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
