Abstract

The embodiment of the disclosure provides a method, a device, electronic equipment and a readable medium for creating a target independent domain of a blockchain system. The target independent domain creation method specifically comprises the steps of receiving metadata of a target independent domain by a domain management tool, generating an creation block of the target independent domain based on the metadata, packaging the metadata and the creation block as registration data, storing the registration data into a system domain in a uplink mode to finish registration of the target independent domain, acquiring the registration data from the system domain and generating module configuration information by the domain management tool in response to receiving a node starting instruction of the target independent domain, and carrying out local initialization and function module configuration by the node of the target independent domain to finish creation of the target independent domain. According to the embodiment of the disclosure, the standardized creation and on-chain registration of the independent domain are realized by setting the system domain and the domain management tool, so that the safety and the expandability of the system are improved.

Description

Method and device for creating target independent domain of blockchain system Technical Field The disclosure relates to the technical field of blockchains, in particular to a creation method, a device, electronic equipment and a readable medium of a target independent domain of a blockchain system. Background With the development of blockchain technology, more and more enterprises and organizations begin to build federated chain platforms to support trusted collaboration across organizations. However, in practical applications, it is difficult for a single chain structure to satisfy diversified service requirements. For example, banks may be involved in multiple business scenarios such as credit, supply chain finance, cross-border payments, etc. if all businesses are deployed on the same chain, this can lead to (1) resource contention and performance bottlenecks. The multiple services share the same consensus engine, storage space and network bandwidth, which is easy to cause resource contention and influence the overall performance. (2) data isolation is difficult. The data between different businesses may have sensitivity difference, and if there is no effective isolation mechanism, sharing the same account book may cause data leakage or illegal access. (3) the complexity of treatment increases. All services share a set of governance rules, and it is difficult to formulate flexible admission policies and entitlement control mechanisms for specific services. (4) extensibility is limited. As the number of services grows, the single-chain architecture is difficult to laterally expand, limiting the flexibility and maintainability of the system. Therefore, it is needed to provide an independent domain which can divide the whole blockchain network into a plurality of independent domains which are logically isolated from each other but can be interacted with each other in a limited way, and each independent domain has own consensus mechanism, account book state and governance rule, so that effective allocation of resources, sensitive data isolation and flexible setting of governance rules are realized.
