On July 7, the Beijing News issued a document, "Haidian will build a 24-hour government supermarket." The article pointed out that Haidian took the lead in launching the blockchain technology application pilot in the city relying on the advantages of scientific and technological innovation. Taking the real estate transaction scenario as an example, through the relevant data sharing chain, the staff does not need to submit Beijing ID card, marriage certificate or divorce certificate, real estate certificate and other materials. The number of on-site verification materials was reduced from 7 to 1 and the verification time was reduced from 15 minutes to 2 minutes. Blockchain technology helps approvers verify the authenticity of materials through data comparisons and reduce the risk of performance.
