Method and device for forming block chain consensus

摘要

The present application discloses a method and device for forming a blockchain consensus. The method comprises the steps of determining a service data handling time, storing service data including the handling time, and forming a consensus on the service data by the nodes in the blockchain upon receiving the service data. And selecting service data subject to consensus formation based on the handling time and performing consensus formation on the selected service data. According to the method provided by the present application, the service data subject to consensus formation is no longer selected based on values corresponding to certain attributes in the service data, and the service data handling node The selection is made based on the handling time when handling. This substantially guarantees a relative equilibrium time for each service data waiting for consensus formation, and avoids the problem of existing technology where some service data has long waiting times for consensus formation. And the service data processing efficiency is substantially improved, and the operational performance of the blockchain is improved.
