Embodiment Construction

[0044] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] see figure 1 , provides a data isolation method in a consortium chain according to an embodiment of the present invention, wherein the consortium chain includes a plurality of nodes, and each node includes a complete main chain, authorization chain and local data pool. The data isolation method in the consortium chain includes: S1, when the node uploads the original data to the chain, it encrypts the original data and stores it in the local data pool; S2, when the encrypted data is successfully stored in the local data pool, the node encrypts the original data Perform a hash operation, and store the hash value obtained after the operation in the main chain of all n...

Abstract

The present invention provides a data isolation method in an alliance chain and a corresponding alliance chain system. The data isolation method includes: S1, when the node uploads the original data, encrypts the original data and stores it in the local data pool; After the encrypted data is successfully stored in the local data pool, the node performs a hash operation on the original data, and the hash value obtained after the operation is stored in the main chain of all nodes in the alliance chain; the local data pool is stored in the authorized chain of the node Authorization information for each piece of encrypted data in . In the data isolation method provided by the present invention, only the uplink data of the node is stored in the local data pool of each node, and the uplink data of other nodes are not stored. Therefore, the data stored by different nodes is different, regardless of the data of different nodes Whether it is the same business data or different business data at the same time, both serve the purpose of isolating and storing data.

Description

technical field [0001] The present invention relates to the technical field of blockchain, and more specifically, to a data isolation method in an alliance chain and a corresponding alliance chain system. Background technique [0002] In the traditional alliance chain, each node of the alliance chain stores a complete set of blockchain data, but in actual business needs, due to privacy protection issues, various organizations hope to achieve a certain data isolation. [0003] Existing data isolation methods in the consortium chain, such as the multi-channel isolation used by Fabric, is based on the business data dimension to isolate, that is, the nodes responsible for the same business dimension data communicate with each other, and the nodes responsible for different business dimension data do not communicate with each other. It ensures the isolation between data of different business dimensions. [0004] However, in actual scenarios, data in the same business dimension in...
