Embodiment Construction

[0148] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0149] Blockchain is a decentralized distributed database technology that is participated by various nodes. The blockchain does not have a central organization, and the consistency of the information of each node is guaranteed through the consensus mechanism of the blockchain. In recent years, in the research process of the blockchain consensus mechanism, more and more technologies have been used to improve the consensus consistency and usability of the consensus mechanism, but the research on nodes dynamically joining or dynamically exiting the alliance chain is extremely scarce .

[0150] Blockchains can usually be divided into three categories: public chains, private chains, and alliance chains. Among them, the alliance chai...

Abstract

The invention discloses a method and device for joining an alliance chain and quitting the alliance chain. The method for joining the alliance chain comprises the steps that a first node receives a joining request broadcasted by a target node; the validity of the joining request is verified based on the valid certificate list; when the validity verification is passed, the first node performs a consensus process in the alliance chain based on the joining request which is not subjected to threshold encryption; and when the joining request passes the consensus, the first node sends a first message to the target node. The alliance chain quitting method comprises the steps that a first node receives a quitting request broadcasted by a target node; the validity of the quitting request is verified based on the invalid certificate list; when the validity verification is passed, the first node runs a consensus process in the alliance chain based on the quitting request without threshold encryption; and when the quitting request passes the consensus, the first node sends a first message to the target node. Based on the process, the efficiency of adding the target node into the alliance chainor exiting from the alliance chain is relatively high.

Description

technical field [0001] The embodiment of the present application relates to the field of blockchain technology, and in particular to a method and device for joining and exiting a consortium chain. Background technique [0002] Blockchain is a decentralized distributed database technology that is participated by various nodes. The blockchain does not have a central organization, and the consistency of the information of each node is guaranteed through the consensus mechanism of the blockchain. In recent years, in the research process of the blockchain consensus mechanism, more and more technologies have been used to improve the consensus consistency and usability of the consensus mechanism, but the research on nodes dynamically joining or dynamically exiting the alliance chain is extremely scarce . [0003] In related technologies, the consensus mechanism of the blockchain does not have the function of nodes dynamically joining or exiting the alliance chain. The process of ...
