The system comprises: a service alliance chain, a judicial chain, a request client, and an evidence storage server. The request client obtains the processed case content after the case is processed, processes the processed case content to generate a digital abstract, and sends an evidence storage request to the evidence storage server, and the digital abstract is carried in the evidence storage request; the evidence storage server receives the evidence storage request, extracts the digital abstract and sends same to an evidence storage client; the evidence storage client corresponds to a block chain node of the judicial chain, stores information on the judicial chain, receives the digital abstract, performs evidence storage and returns an evidence storage record ID; the evidence storage server also returns the evidence storage record ID, the digital abstract, and the case content to an information storage node; and the information storage node corresponds to the block chain node of the service alliance chain, and receives and stores the evidence storage record ID, the digital abstract, and the case content.
