Node management method and device and electronic equipment

Abstract

The embodiment of the invention provides a node management method and device and electronic equipment. The method is applied to an alliance chain network, the alliance chain network comprises a plurality of nodes, the plurality of nodes comprise a management node, an accounting node and a common node, the method comprises the following steps: a first node acquires transaction data, and the first node is any one of the plurality of nodes; the first node determines an access permission control strategy of the transaction data and encrypts the transaction data according to the access permission control strategy to generate encrypted data corresponding to the transaction data, and the access permission control strategy comprises a node attribute set of a target node in the plurality of nodes;and the first node broadcasts the encrypted data in the alliance chain network, so that after receiving the encrypted data, the target node decrypts the encrypted data by using own attribute information to obtain transaction data. Through the application, the authority control function and the privacy protection function of the node in the alliance chain can be realized, so that the complexity ofnode management is reduced.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a node management method, device, and electronic equipment. Background technique [0002] The blockchain has the characteristics of distributed structure, transparency and credibility, and information cannot be tampered with. Using the blockchain to build a data sharing platform can realize trusted data exchange without relying on the credit endorsement of the third-party data sharing platform. There are three types of chains: public chains, private chains and alliance chains. [0003] At present, the technologies for managing consortium chains mainly involve Fabric, JPMorgan Quorum, Corda, etc. These technologies generally use the public key infrastructure (Public Key Infrastructure, PKI) system to solve the node management problems existing in the consortium chain, but the PKI system involves The operation process of node management is relatively cumbersome.

[0003] At present, the technologies for managing consortium chains mainly involve Fabric, JPMorgan Quorum, Corda, etc. These technologies generally use the public key infrastructure (Public Key Infrastructure, PKI) system to solve the node management problems existing in the consortium chain, but the PKI system involves The operation process of node management is relatively cumbersome. For example, when the transaction initiator needs to send transaction data to other N nodes in the alliance chain network, it needs to encrypt the transaction data N times and send them to N nodes respectively. This way of operation Inefficient and waste of system resources
