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. The data is stored in a private information, and the blockchain operation of the account cannot be restricted

Abstract

The invention discloses a block chain authority control method, a device and a node device. The method comprises the steps of: receiving the target information transmitted by the node device; obtaining the account address of the account configured by the node device; according to the account address, obtaining the account authority corresponding to the account address from a preset block storing the account address and the account authority corresponding to the account address; and performing corresponding processing of the target information according to the account authority.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain authority control method, device 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 non-tamperable, non-forgeable and fully traceable. [0003] The blockchain network is based on a P2P network, and each P2P network node that participates in transactions and block storage, verification, and forwarding is a n...
