Abstract
Disclosed herein are methods, systems, and apparatus, including computer programs encoded on computer storage media, for performing an attestation verification. One of the methods includes sending an attestation request to a relay system node by a relay system controller. The relay system controller receives an attestation evidence of the relay system node from the relay system node. The relay system controller sends the attestation evidence of the relay system node to an attestation verification server. The relay system controller receives an attestation verification report from the attestation verification server. The relay system controller sends the attestation verification report to a relay system smart contract.
