Abstract: Provided are a method and apparatus for operating blockchain system, a device and a storage medium. The method is described below. To-be-processed blockchain data is processed through a kernel engine of a blockchain system, a kernel component call request is generated based on a kernel component interface during the processing process, and a kernel component is called according to the kernel component call request, where at least one kernel component is provided. The kernel component call request is executed through the kernel component to execute processing of a set component function and satisfy a processing requirement for the to-be-processed blockchain data.
