This standard defines a technical reference framework and terminology for the platform of blockchain in electronic contracts. Functional requirements and technical indicators are also defined.
Blockchain interoperability is the ability of two or more blockchain systems or applications to exchange information and to mutually use the information that has been exchanged. The interfaces and protocols play a very important role in realizing interoperability. Therefore, the standard of cross-chain interoperability interfaces and protocols, especially those for data authentication and communication among homogeneous and heterogeneous blockchains systems, is needed. Such protocols coordinate blockchains while supporting multiple cross-chain models and levels to meet business demands without the need to customize gateways or exchanges for specific use cases. Provided in this standard are an infrastructure of cross-chain interoperability, as well as interfaces and protocols of data authentication and communication for homogeneous and heterogeneous blockchain interoperability. The protocols include the distributed identity protocol, metadata protocol, on-chain proof transformation protocol, and cross-chain communication protocol.
This standard defines a baseline architectural framework and defines functional roles for blockchain-driven supply chain finance (SCF) implementations, e.g., core enterprise, supplier, bank, blockchain platform provider, and so on. The procedures of registration, asset issuance, asset transfer, financing based on asset on chain, asset clearing and settlement, and asset tracing, are explained. Finally, the technique requirement of the business system, and blockchain platform are discussed.
Data format requirements for blockchain systems are established in this standard. This standard addresses data structures, data types, and data elements.
This standard specifies the terminology, technical reference framework, basic functional requirements, and technical indicators for the platform of blockchain-based e-commerce transaction evidence collecting, which is the foundation of digital business interactions.
This standard establishes a system designed to trade data through domain-independent and principled marketplaces operating under a unified architecture. It defines terminology, a reference model, and the roles and functions of data providers, data users, and data marketplaces. The standard provides an overview of the data trading system using its reference model.
This standard defines an evaluation model and evaluation index system for using blockchain in low carbon zones, combining carbon emission scenarios and zone types. This standard also defines the technical requirements and management requirements for using blockchain for low carbon zones, including carbon accounting data sources, data storage, data interaction, data accounting, emission factor database establishment, carbon accounting method selection and prediction.
This standard provides a framework for the implementation, and interaction utilizing Web 3.0 (Web3) in healthcare and life sciences involving privacy challenges. Web 3.0 represents the next iteration of the evolution of the web and is built upon the core concepts of decentralization, openness, and greater user utility. Digital Ledger Technology (DLT) tokens, smart contracts, transactions, assets, networks, off-chain data storage and access architectural patterns, and Web3 permissioned and permission-less DLT are included in the framework.
The standard defines the Entity Risk Mutual Assistance Model (RMAM) based on blockchain technology, including the involved entities of interest, the relationship between entities, organizational framework, and design method. A framework of blockchain-based Internet of Things (IoT ) data management is defined in this standard. It identifies the common building blocks of the framework that blockchain enabled during IoT data lifecycle including data acquisition, processing, storage, analyzing, usage/exchange and obsoletion, and the interactions among these building blocks.
Defined in this standard is the general process of cryptocurrency payment between consumers and merchants. This process describes how a consumer purchases goods or services with cryptocurrency and how the merchant receives fiat money in return. It involves multiple aspects such as cryptocurrency payment operators playing an agent role, consumers owning cryptocurrency, merchant accessing to a cryptocurrency payment platform, banks, and cryptocurrency exchanges.
Described in this standard is the blockchain-based application reference architecture of e-invoice business, including roles of participants, typical business scenarios, platform frameworks, and security requirements.
A framework of a custodian service for cryptocurrency and token assets is defined in this standard. Custodian reference technical architecture, business logic description, custodian service business models, digital asset evaluation criteria, operational procedure models, and regulatory requirement support models are included in this framework.
