[0002] The blockchain protocol can be understood as a protocol that describes a set of consistent behaviors that must be followed to generate some data in a certain process and data structure format. The blockchain system is a set of software programs that are automatically executed according to the defined blockchain protocol. It is a distributed system composed of multiple consensus nodes, and each node is usually operated by a participant. The installation, deployment, and program upgrade of such a system require negotiation with multiple participants. From the first installation to the subsequent program upgrades caused by changes in the blockchain protocol, multiple negotiations and tests are required. If the executors of each participant are not well prepared for the installation and upgrade steps or knowledge, the entire system will be unavailable (distributed system consistency problem), which is not conducive to the continuous availability of the blockchain system. Summary of the invention

[0030] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0031] The following is a detailed description of a metadata-based blockchain system management solution involved in this specification through a specific example.

[0032] Key Terms

[0033] Blockchain: It is a new distributed infrastructure and computing paradigm that uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses smart contracts composed of automated script code to program and operate data. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable, full traceability, traceability, openness and transparency, and collective maintenance". Based on these characteristics, blockchain has laid a solid foundation of trust, created a reliable cooperation mechanism, and has broad application prospects. According to the access mechanism classification, blockchain is divided into public chain, alliance chain and private chain.

[0034] Blockchain system: It is a set of software programs that are automatically executed according to the defined blockchain protocol. It is a distributed system composed of multiple consensus nodes, and usually each node has a participant responsible for operation.

[0035] Metadata: also known as intermediary data or relay data, is data about data, mainly information describing data properties, used to support functions such as indicating storage location, historical data, resource search, and file records. Metadata is a kind of electronic catalog. In order to achieve the purpose of cataloging, it is necessary to describe and collect the content or characteristics of the data, so as to achieve the purpose of assisting data retrieval. Metadata is information about the organization of data, data domains, and their relationships. In short, metadata is data about data, descriptive information about data and information resources. In the field of software construction, metadata is defined as data that is not an object to be processed in the program, but changes the behavior of the program by changing its value. It plays a role in controlling the behavior of the program in an interpretive way during the running process. By configuring metadata with different values ​​at different locations in the program, you can get program behavior equivalent to the original one.

[0036] YAML: is a recursive abbreviation of "YAML Ain't a Markup Language". YAML's syntax is similar to other high-level languages, and can simply express data forms such as lists, hash tables, and scalars. It uses whitespace indentation and relies heavily on appearance, making it particularly suitable for expressing or editing data structures, various configuration files, dumping debugging content, and file outlines.

[0037] JSON: It is a lightweight data exchange format. It is based on a subset of ECMAScript (the js specification developed by the European Computer Association) and uses a text format that is completely independent of programming languages ​​to store and represent data. The simplicity and clear hierarchical structure make JSON an ideal data exchange language. It is easy for people to read and write, and it is also easy for machines to parse and generate, and it effectively improves network transmission efficiency.

[0038] Embodiment 1

[0039] Reference Figure 1 , which is a schematic diagram of a blockchain system based on metadata management according to an embodiment of the present invention. The system includes at least a metadata management subsystem and a plurality of blockchain system nodes.

[0040] The metadata management subsystem includes metadata definition, interpreter, executor, and metadata update corresponding functions.

[0041] First, the metadata of the blockchain system is defined. The elements of the metadata include at least the version number of the blockchain system metadata, the blockchain engine and its version number, the on-chain configuration, and the off-chain system configuration. It should be noted here that the same blockchain system can only have one copy of metadata, that is, each node of the blockchain system should receive and execute the same metadata. Secondly, the corresponding metadata interpreter and metadata executor are created and deployed in the blockchain system. Thirdly, the metadata is parsed by the metadata interpreter and sent to the metadata executor, so that the blockchain system completes the system configuration according to the metadata. The executor installs the corresponding blockchain engine according to the blockchain engine and its version number of the metadata, runs the blockchain according to the on-chain configuration and the off-chain system configuration of the metadata, and generates blockchain data according to the blockchain protocol. When the blockchain system needs to be upgraded, the new metadata is distributed to the nodes of the blockchain so that the metadata interpreter and the metadata executor automatically execute the new metadata and update the blockchain system configuration. It should be noted here that when the definition of the blockchain system metadata changes, the corresponding blockchain system metadata version number must also change, so that the metadata interpreter interprets different metadata formats according to different metadata version numbers.

[0042] The blockchain system node actually carries and runs the metadata interpreter and metadata executor. After receiving the metadata, the metadata is parsed by the metadata interpreter and sent to the metadata executor, so that the blockchain system completes the system configuration according to the metadata. After the nodes of the blockchain system complete the system configuration according to the metadata, blockchain data is generated according to the blockchain protocol.

[0046] Optionally, the parameter items included in the metadata element are increased or decreased according to the configuration requirements of the blockchain system. At the same time, the metadata is described in a data exchange format, and the data exchange format includes one of YAML or JSON. It should be noted here that when the blockchain system metadata definition changes, the corresponding blockchain system metadata version number must also change, so that the metadata interpreter interprets different metadata formats according to different metadata version numbers. The following is a metadata definition of an embodiment of the present invention using YAML as an example:

[0050] Step 102: Create and deploy corresponding metadata interpreters and metadata executors in the blockchain system.

[0051] Step 103: The metadata is parsed by the metadata interpreter and sent to the metadata executor, so that the blockchain system completes the system configuration according to the metadata. Figure 3 As shown, it is the working process of the actuator in one embodiment of the present invention:

[0052] Step 131: Install the corresponding blockchain engine according to the blockchain engine and its version number of the metadata;

[0053] Step 132: Run the blockchain according to the on-chain configuration of the metadata and the off-chain system configuration;

[0054] Step 133: Generate blockchain data according to the blockchain protocol.

[0055] Step 104: When the blockchain system needs to be upgraded, the new metadata is distributed to the nodes of the blockchain system so that the metadata interpreter and the metadata executor automatically execute the new metadata and update the blockchain system configuration.
