Problems solved by technology

[0004] From the above, the blockchain in the related technology, since the nodes can join the chain without restrictions, the data on the chain is completely open, which is suitable for some public information storage that does not involve privacy, but it is not suitable for the storage of information on the blockchain. Information storage with data privacy

Embodiment Construction

[0039] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0040] see figure 1 It is a schematic diagram of a blockchain network in related technologies. Each node in the blockchain network establishes a connection through a P2P peer-to-peer network, and each node that joins the blockchain network can synchronize all data on the current blockchain, making several copies of the blockchain data are saved to multiple nodes on the blockchain.

[0041] In the embodiment of the present disclosure, in order to protect the data in the blockchain, different user nodes configured with different accounts are distinguished and permission settings are performed, so that user nodes configured with different accounts can access t...

Abstract

The present invention discloses a rights control method, an apparatus, a system and a node device of a block chain, the method comprising: writing a correspondence relationship between a preset account character and a privilege into a block of a block chain; The user's node configured in the block chain is configured to control the authority of the user node in which the target account is configured based on the correspondence relationship and the role of the target account. Through the setting of the role and the authority of the block chain account, the user node with different account is configured according to its own role and authority so that only the corresponding account can access the block chain network and synchronize the block chain Data and access to the scope of the data within the scope of the realization of the block chain data protection to ensure that the block chain data security and privacy.

Description

technical field [0001] The present disclosure relates to the field of information technology, and in particular to a block chain authority control method, device, system and node equipment. Background technique [0002] The blockchain is a decentralized distributed database system that is jointly maintained by all nodes in the blockchain network. It is composed of a series of data blocks generated based on cryptographic methods. Each data block is a block in the blockchain. a block. According to the order of generation time, the blocks are linked together in an orderly manner to form a data chain, which is vividly called a blockchain. Blockchain has its own unique block generation, transaction generation and verification protocols, and has security features such as unchangeable, unforgeable and fully traceable. [0003] In related technologies, the nodes of the blockchain are connected through a P2P peer-to-peer network, and each newly added node will synchronize all the d...
