附件2：BDL SC在研标准介绍

标准名称 标准范围 主席单位
P2418.7 Standard for the Use of Blockchain in Supply Chain Finance This standard defines a baseline architectural framework and defines functional roles for blockchain-driven supply chain finance (SCF) implementations, e.g. core enterprise, suppliers, buyers, banks, Blockchain platform providers and so on. In addition, this standard outlines uses cases and business flows for SCF based on blockchain, and specifies the implementation functional and security requirements. Ant Financial
P3201 Standard for Blockchain Access Control The standard establishes access control requirements for blockchain systems. The standard addresses the following access control attributes of the system, including but not limited to: a) Node permissions – the permissions of block generation, block synchronization, block verification and broadcasting, and sending transactions. b) Smart contract access permissions – interface access control, user access control, and hybrid access control. c) User permissions – registered user permissions and unregistered permissions. The concept of role is applied to differentiate the permissions of registered users, which means permissions vary according to the role of a user. d) Global permissions – user access to deploy smart contracts, and to read smart contracts. Wanxiang Blockchain
P3202 Standard for Capability Evaluation Requirements of Blockchain Practitioners This standard defines the types of occupations, competency requirements, and evaluation methods of blockchain and distributed ledger technology for service practitioners, including but not limited to competency elements, evaluated process, and employment grade. This standard applies to the ability evaluation and training of blockchain and distributed ledger technology service practitioners. China Electronics Standardization Institute
P3203 Standard for Blockchain Interoperability Naming Protocol This standard defines a set of protocols that enable Blockchain networks to locate each other’s trusted nodes through standardized names.
