Using Blockchain Evidence in China’s Digital Copyright Legislation to Enhance the Sustainability of Legal Systems

To achieve sustainable development of social systems, it is necessary to modernize the legal system, which is the foundation of any society, to increase the efficiency of resources and simultaneously optimize the performance of the environment and society. The immutable and timestamped features of blockchain offer a robust solution for tracking and authenticating digital copyright evidence, thereby enhancing the integrity and transparency of judicial systems. This ensures that the integration of blockchain into legal systems not only advances technological efficiency but also promotes environmental consciousness. Through comprehensive analyses that integrate questionnaires, interviews, case studies and legislative assessments, this research reveals that there are still problems in the application of blockchain evidence in China’s judicial practice, such as insufficient and stable credibility, inadequate database storage, deficient original rights mechanisms, and the imperfect application of rules of evidence. These problems can be solved by enhancing correspondence legal systems, such as establishing an officially trusted copyright certificate blockchain, creating a blockchain copyright certificate technology supervision system and formulating specific laws and regulations on the application and identification of blockchain evidence. As such, our study contributes to aligning blockchain with judicial records, supporting the sustainable development goals of social systems, fostering institutional justice and social progress.
