Academician of the Academy of Engineering Shen Changxiang: To promote the innovation and development of blockchain, we must do a good job of hierarchical protection of system security and system resource security

According to the Beijing News, at the recent work exchange meeting on the key laboratory of the Ministry of Industry and Information Technology of Blockchain Technology and Data Security, the academician of the Chinese Academy of Engineering, Shen Changxiang said that blockchain is a new type of network application. Full use of cryptographic technology can solve block problems. The distributed ledger of the chain cannot be tampered with and cannot be denied, and the secret itself must be strengthened. He further stated that two factors must be considered, one is systemic security and business information process security; the other is system resource security, business application information security must ensure transactions are valid and reach consensus, and system resource security cannot be tampered with and cannot be interrupted. He said: "We want to promote the innovation and development of blockchain, and we need to do a good job of protecting the two elements."
