Abstract

The invention discloses a consortium chain architecture that provides multi-level data privacy. The consortium chain architecture includes: multiple nodes deployed on the consortium chain by multiple organizations, and one or more channels for data transmission between the nodes ; At least one of the nodes in the same channel is configured with a centralized system for data interaction with the node; the node is provided with private data for storing sensitive data, and the sensitive data is the same channel The data with access restrictions between the nodes in the network, the private data is the data with access rights set in the nodes, and the rights of private data can be flexibly configured to meet the data privacy requirements of different organizations on the chain. It solves the problem that the alliance chain needs multiple levels of data privacy protection, provides data privacy between channels, within channels and between nodes, and greatly improves the privacy and security of alliance chain data.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to an alliance chain architecture providing multi-level data privacy. Background technique [0002] As we all know, blockchains are generally divided into three types: public chains, private chains, and alliance chains. The three can be divided according to the degree of decentralization: the public chains with the highest degree of decentralization, such as Bitcoin and Ethereum Public chains such as public chains; and private chains with the lowest degree of decentralization, whose network is completely controlled by an organization or institution. In the blockchain between the public chain and the private chain, the nodes on it are generally composed of corresponding entities or organizations. Participants join the network through authorization and form an alliance of stakeholders to jointly maintain the operation of the blockchain. [0003] Although the blockcha...
