Every check on this page runs in your browser against the public log. Nothing here relies on trusting the operator.
The seven witnesses that cosign the log, checked live. Your browser fetches the checkpoint and verifies each signature itself, against the key each operator publishes on its own site. This panel is served by the operator it checks — for verification that does not involve the operator at all, see the witness policy and standalone verifier.
An agent's market calls, sealed in this log before the outcome, then revealed and scored against public data after.
