According to the Beijing News, on January 15, the third meeting of the 15th Beijing People's Congress considered the work report of the Municipal High People's Court and the work report of the Municipal People's Procuratorate. The two reports repeatedly mentioned the promotion of information technology for prosecution work, and new technologies represented by blockchain are fully enabling prosecution. Among them, the Beijing Internet Court “Tianping Chain” has greatly improved work efficiency by using technology and smart contract technology. It has solved the “trilemma” of difficulty in obtaining, storing, and identifying electronic evidence in Internet trials, and has now completed cross-linking. There are 19 blockchain nodes and hundreds of millions of cross-chain certificate data. Automatic contract technology enables the automatic execution of the mediation agreement.
