Zhejiang Daily published an analysis article "Thinking of Blockchain Technology and Judicial Practice". The article points out that after China clearly defined electronic evidence as a statutory type of evidence in 2012, the number of cases involving electronic evidence has spurted up. However, compared with the widespread use of electronic evidence, courts often fail to prove the authenticity and completeness of electronic evidence, and their acceptance rate is not high. Its roots are in the physical characteristics of electronic evidence that are easily tampered with and the lack of necessary technical discrimination ability of judges. However, the distributed ledger technology of the blockchain effectively makes up for the shortcomings of electronic evidence and greatly reduces the requirements for judges' technical discrimination ability. The article also pointed out that the application of blockchain technology in electronic evidence makes up for the shortcomings of the current evidence system and will greatly reform the existing trust structure centered on courts, judicial appraisal agencies and expert witnesses, which is in line with the current acceleration of the digital society and The development trend of digital government and digital governance is conducive to improving the objectivity and efficiency of judicial trials. However, it must be noted that emphasizing the role of science and technology in social governance does not mean less responsibility and responsibility, but puts forward higher requirements for the ability and level of scientific governance and democratic governance in relevant departments.
