Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for enhancing blockchain network security. Implementations include receiving a request for data from the data source, transmitting the request to a relay system that is external to the blockchain network and that includes a multi-node cluster including a plurality of relay system nodes, receiving a result provided from a relay system node, the result being digitally signed using a private key of the relay system node, verifying that the relay system node is registered, verifying an integrity of the result based on a public key of the relay system node and a digital signature of the result in response to verifying that the relay system node is registered, and transmitting the result to a client in response to verifying the integrity of the result.
