According to CoinMeta, the international standard led by China, "Blockchain and Distributed Ledger Technology: Technical Framework and Functional Requirements for Blockchain as a Service," was recently approved for development by the International Organization for Standardization (ISO). Countries such as Germany, the United Kingdom, Ireland, Japan, Portugal, and Uganda will participate in its formulation. This standard will clarify technical requirements for infrastructure and networks, service management and smart contracts, data interaction, and security protection, providing a reference for the construction of global blockchain platforms, enterprise selection, and the promotion of blockchain applications.
