Consortium Blockchain Security Solutions

SlowMist technology is committed to the construction of blockchain ecological security and has implemented comprehensive security solutions for many of the well-known digital currency exchanges, wallets, public blockchains, smart contracts and other projects in the global public blockchain ecosystem. SlowMist Technology, as the Vice-director Unit of Fujian Provincial Blockchain Development Promotion Association and Fujian Provincial Blockchain Association, was the first batch to be selected into the "2018 China Blockchain Industry White Paper" by the Ministry of Industry and Information Technology. At the same time, SlowMist is also one of the five-member units of the Guangdong-Hong Kong-Macao Greater Bay Area Blockchain and Cyber Security Technology Joint Lab. With the development of the consortium blockchain ecology, in 2019, SlowMist Technology has cooperated with the Internet Information Office of multiple provinces to implement a multi-level security audit for the consortium blockchain of the local government, enterprise, and public institution from underlying technology to application layer, and found vulnerabilities and weak points of multiple scenarios, multiple applications, and multiple forms of consortium blockchain systems and their supporting systems. SlowMist technology has implemented a number of security studies in the research area of the consortium blockchain and has achieved results. It has systematic experience in multi-scenario blockchain system security practices. The consortium blockchain full-cycle security construction solution proposed by SlowMist Technology is committed to improving the security and controllability of enterprises to the currently immature blockchain technology system, allowing the blockchain security system to be multi-leveled and standardized, thereby protecting the area blockchain applications can be implemented quickly and securely.
