According to Xinhuanet, blockchain technology is becoming an important scientific and technological force for Zhejiang to promote social credit governance. Xu Xiaowei, director of the Hangzhou Internet Notary Office, said that the blockchain lottery system includes blockchain lottery and blockchain shake. The blockchain lottery system performs a rolling lottery on all participating numbers through a cryptographic random algorithm embedded in the blockchain element, and displays the final result in a large screen and recorded in real time. At the same time, the results of each group draw will be automatically updated to the blockchain to ensure that the results cannot be tampered with. Since its official launch in July this year, it has accumulated more than 200 million passengers.
