Abstract
Implementations of the present application disclose a method and device for processing a service request. If a service request passes consensus verification, each consensus node stores a digest of service data in a blockchain, instead of storing the service data in the blockchain. As such, the digest of the service data is stored in the trustworthy blockchain, and authenticity of the service data can still be verified. In addition, the service data is not stored in the blockchain so that the service data cannot be obtained by a blockchain node irrelevant to the target service. Therefore, each consensus node does not need to consume computing resources to encrypt the service data any more, thereby improving efficiency of performing consensus verification on the service request by each consensus node.
