Blockchain service acceptance and consensus method and devices

Abstract:

This specification describes techniques for handling a blockchain service. A service request sent by a client is received by a first application of a first consensus node of a blockchain network, where the first consensus node includes the first application, a second application, and a database. To-be-sent service data is determined based on the service request. The to-be-sent service data is stored in the database by the first application. A determination is made as to whether a predetermined condition is satisfied. If it is determined that the predetermined condition is satisfied, the to-be-sent service data is retrieved from the database by the first application or the second application. The to-be-sent service data is transmitted to a second consensus node of the blockchain network.
