Embodiment Construction

[0095] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0096] At present, blockchain systems can be mainly divided into three categories, namely public chains, private chains and alliance chains. The main difference between these three types of blockchains is the difference in open objects. The public chain can be open to everyone, can be read by anyone, can send transactions and the transactions can be ...

Abstract

The application discloses a method for communication between the nodes of a block chain, which includes the following steps: a second node receives a first communication request sent by a first node,wherein the first communication request includes the digital certificate of the first node, and the digital certificate of the first node is stored in a block chain to which the first node and the second node belongs; the second node verifies whether the digital certificate of the first node is legal according to the first communication request and certificate legality information, wherein the certificate legality information is stored in the block chain and used to reflect the legality state information of the digital certificate of a node; and if the digital certificate of the first node islegal, the second node determines whether to establish a communication connection with the first node. The application further discloses a method and a device for managing digital certificates based on a block chain, and corresponding electronic equipment.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a method, device and electronic equipment for inter-node communication of blockchain, and a method, device and electronic equipment for managing digital certificates based on blockchain. Background technique [0002] With the development of computer technology, blockchain technology (also known as distributed ledger technology) is favored for its advantages of decentralization, openness, transparency, immutability, and trustworthiness. It is widely used in smart contracts, securities transactions, e-commerce, The Internet of Things, social communication, file storage, proof of existence, identity verification, equity crowdfunding and many other fields have been widely used. [0003] At present, blockchain systems can be mainly divided into three categories, namely Public Blockchain, Private Blockchain and Consortium Blockchain. The main difference between these t...
