The inference runs inside an enclave that produces a 213 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 inexpensive script for real reasoning cannot produce the quote, so it pays for the enclave anyway and gets nothing. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":0,"sig":"3QYKsPueBhHcgjfDasQ3ARSo3GDt7wMspJDWwTeCGpHwZ8qj83p1ipDftcxacrkqT4AJY2q9gohmHnfWd4GNHmue"},"checkpointed":{"height":237435,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:50:15.601Z","checkpoint_height":237435,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
