The Qingdao Arbitration Commission cooperated with well-known domestic Internet companies to develop and build an Internet arbitration case-handling platform and China's first electronic evidence platform using 5G network slicing technology. The platform has officially operated. More than 190,000 electronic evidences have been stored since its operation in August. The electronic evidence platform uses time stamps and digital cryptography to record data in data blocks composed of time series and store the data in distributed network computers. The platform communicates with other permitted institutions such as courts, arbitrations, lawyers, notaries, and judicial appraisals through multiple ports, and cooperates in supervision. Under the blockchain technology, all institutions form a judicial alliance chain.
