Abstract:
A verifiable computing system is presented. A worker computing device of the verifiable computing system receives a primary program and a verification logic that are generated based on a target function. The worker computing device includes a main processor and a coprocessor. The main processor is configured to execute the primary program and the coprocessor is configured to implement the verification logic. Telemetry is collected from the main processor executing the primary program and provided to the coprocessor. The coprocessor implementing the verification logic uses the telemetry to generate a proof. The proof is provided to a verifying computing device for determining whether the primary program is tampered with.
