Scope

Scope: In order to standardize the construction of security for public blockchain systems in China and ensure that the security technology of public blockchain systems is technically advanced, economically reasonable, and applicable in practice, this guideline is hereby formulated. This guideline applies to the construction and modification of public blockchain systems with general commonality and security engineering, and is also applicable to third-party institutions' evaluation or self-evaluation of the security of public blockchain systems. The construction of security engineering for public blockchain systems should adhere to national policies and technical and economic guidelines for blockchain security management, comply with relevant national technical systems and standards, and closely integrate with the rapid development of public blockchain. It should possess security and rapid scalability and upgrade capabilities. The construction of security engineering for public blockchain systems should conduct thorough investigation and analysis, and fully consider factors such as the impact of new businesses and technologies on the security structure and capabilities of public blockchain systems. In addition to complying with this specification, the construction of security engineering for public blockchain systems should also comply with current national standards. Main technical content: 1.
