Read public data for blockchain networks using a highly available and reliable execution environment

摘要

Methods, systems, and devices for enhancing blockchain network security, including computer programs encoded on computer storage media. Embodiments include a step of receiving a request for data from a data source and a step of sending the request to a relay system that is outside the blockchain network and includes a multinode cluster that includes multiple relay system nodes. The step of receiving the result provided by the system node, the result of which is digitally signed using the private key of the relay system node, and the step of verifying that the relay system node is registered. In response to verifying that the relay system node is registered, the steps to verify the integrity of the result based on the public key of the relay system node and the digital signature of the result, and verify the integrity of the result. Includes steps to send the results to the client in response to what you have done.
