Communication method and device

Abstract

The invention discloses a communication method and device. The method and the device are applied to a blockchain system comprising a plurality of nodes. At least one node in the plurality of nodes comprises neighbor nodes. The neighbor nodes are nodes directly communicating with the node. The method comprises the steps that for at least one neighbor node, the node determines a network connection state value between the node and the neighbor node through a connection message; and if it is determined that the network connection state value exceeds a first threshold, data transmission with the neighbor node through a connectionless message is stopped.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and device. Background technique [0002] In modern life, it is often necessary to prove the existence of a certain data (thing), that is, the storage of data, such as written articles, historical operation instructions, signed contracts, etc. At this time, it needs to be certified by a third-party certification agency , this certification method has extremely high requirements on the credibility of the certification body, and the operation is cumbersome, the cost is high, and the timeliness is poor. In order to solve the above-mentioned various problems in data storage through third-party certification agencies, there have been many solutions for data storage through blockchain, which can be solved well by using the decentralized structure and immutable characteristics of blockchain. the above problems. The currently popular blockchai...

Problems solved by technology

The currently popular blockchain technology is based on a distributed network on a global scale, which is limited by external operators and transmission distances, and lacks effective control

[0003] With the development of the business, the transaction volume of the transaction system is gradually increasing, and there will be a transaction peak in a certain period of time. When a large amount of transaction data floods into the blockchain network, the broadcasting capability of the blockchain network and the transaction data processing of the accounting nodes A bottleneck will appear in the capacity of the network, causing the business to fail to run normally, and even broadcast storms

[0004] In addition, messages are sent through network-wide broadcast. Due to data transmission on the Internet, there are network problems such as inevitable delays. The current distributed network currently has no error correction mechanism, and it is difficult to make up for packet loss and error packets.
