Abstract

The embodiment of the invention provides a block chain hierarchical consensus method, a block chain network system and a block chain node, and belongs to the technical field of block chains. The method comprises the steps: service data to be subjected to consensus is acquired, and a visible permission of the service data is determined; when the visible permission is a first-class visible permission, the service data is sent to a consensus node in a local chain to be subjected to consensus processing through the consensus node in the local chain; when the visible permission is a second-class visible permission, the service data is sent to a consensus node in a global chain to be subjected to consensus processing through the consensus node in the global chain. It can be seen that the servicedata can be shared selectively in the local chain or the global chain on the basis of the different visible permissions of the service data, that is to say, when the number of Internet of Things nodes is large and the network environment is diverse, the data can be selectively opened according to the trust and data privacy degree, therefore, the propagation range of the service data is greatly narrowed, and the data privacy protection effect is improved.

Description

technical field [0001] This application relates to the technical field of block chain, specifically, to a layered consensus method of block chain, block chain network system and block chain nodes. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is a distributed Internet database technology. The network built based on blockchain technology can be called a blockchain network, which contains network nodes (also called blockchain nodes, hereinafter referred to as nodes), and each node corresponds to at least one Blockchain, each blockchain contains at least one block. The blockchain network (or blockchain technology) has the characteristics of decentralization, openness, transparency, non-tampering, and trustworthiness. Based on these characteristics, the application fields of blockchain technology are becoming more and more extensive. [0003] In the IoT application scenario, due to the large number of IoT nodes and diverse n...
