On the evening of February 7, SheKnows opened the second debate of the year-"The pain of entrepreneurship, how can the blockchain team survive the death?" Was officially held. Wu Xiao, founder and CEO of Pure White Matrix, said that I think blockchain can play a lot of roles in fighting the epidemic, such as information collaboration across trusted subjects, but these take time. For example, the United States and African hospitals constitute subjects of mutual distrust, but data coordination is required. Such as the electronic medical records of the blockchain. The medical records of Hospital A and Hospital B are definitely not working. If there is an alliance chain, led by the country, user information is stored on the chain through national secrets, including drug allergy history, drug records, surgery records, etc., and then give the user a private key / password. The user has performed pre-treatment in Hospital A, such as when transferring to Hospital B, and can get this password. When he arrives at Hospital B, he can quickly get his previous medical information by giving his attending doctor the password.
