T/CTAAC 003-2020 Blockchain anti-counterfeiting traceability data format general requirements

Scope

Scope: This standard specifies the data formats for the circulation and traceability information of items, anti-counterfeiting code information, and other data in the blockchain anti-counterfeiting and traceability information system, and provides design specifications for programming and developing the data linking and query functions of blockchain-based anti-counterfeiting and traceability systems. This standard applies to information systems that use blockchain for anti-counterfeiting and traceability. It also applies to providing technical support for the identification of data linked to different systems during operation. Main technical content: Blockchain (Blockchain) is a distributed ledger that connects data blocks in chronological order using cryptographic calculations. Blockchain is developed and operated using technologies such as P2P technology, cryptography, consensus algorithms, and smart contracts, which ensure that the blockchain ledger cannot be tampered with or forged. Blockchain provides a mechanism for transferring and exchanging information and value in untrusted environments, and is the cornerstone for building a future internet of value and trust. In the field of anti-counterfeiting and traceability, the public, fair, and unmodifiable bookkeeping function of blockchain is particularly suitable for authentic recording of item attribute information and item circulation information. On the one hand, the unmodifiable nature of logistics information enables the mutual verification of circulation information at various stages of an item's life cycle, making it easier than ever to detect counterfeiting and greatly increasing the difficulty and cost of counterfeiting circulation information. On the other hand, linking item anti-counterfeiting codes to the blockchain plays a supervisory role in tracing and detecting the illegal circulation and use of anti-counterfeiting codes, which greatly enhances the management level of anti-counterfeiting codes a
