According to Netease Technology, Huawei founder Ren Zhengfei recently said in a dialogue event that information security is always a big problem. Just like the relationship between spear and shield, there must be a spear in the shield. But after the emergence of quantum computers, many computational problems can be solved. He said: "Many people say how great the blockchain is, but it is worthless in the face of quantum computing." For information security issues, Ren Zhengfei believes that he can turn to the law.
