Block chain information transmission method and system based on satellite-ground collaboration

Abstract

The invention provides a block chain information transmission method and system based on satellite-ground collaboration. The method comprises the following steps that a block chain core node receivesto-be-transmitted information sent by a block chain node, and verifies the to-be-transmitted information; after the verification is passed, the block chain core node sends the to-be-transmitted information to a communication satellite; and the communication satellite receives the to-be-transmitted information and broadcasts the to-be-transmitted information to each block chain node and the block chain core node through a wireless channel, so that each block chain node and the block chain core node carry out corresponding processing on stored block chains according to the to-be-transmitted information. According to the method and the system, the communication satellite broadcasts the information to each block chain node at the same time, so that point-to-point transmission in a P2P broadcasting scheme is avoided, the information transmission efficiency of the block chains is improved, the synchronization time of the nodes of the whole network is shortened, and the transaction efficiencyof a block chain system is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and system for transmitting blockchain information based on satellite-ground coordination. Background technique [0002] Blockchain is a distributed digital ledger system, which has the characteristics of distributed storage, decentralization, cryptographic security and immutability. In the blockchain system, the transaction information between accounts is signed by the transaction initiator with asymmetric encryption technology and stored on the block. Each block contains a timestamp and the hash value of the previous block header, so that All blockchains together form a blockchain. [0003] The generation of new blocks is determined through a consensus algorithm, which includes workload proof, equity proof, and share authorization proof. Taking the consensus algorithm using proof-of-work as an example, since the entire blockchain is stored on each node, if ...

AI Technical Summary

Problems solved by technology

For the traditional IP-based network architecture, through the point-to-point (p2p) broadcast scheme, each node needs to perform a data transmission, which will bring a great burden to the network, and it is easy to happen in the case of frequent transactions. network congestion

Since it takes a certain amount of time for each transaction or the generation of a new block to be broadcast, the confirmation time of the block or transaction needs to meet the transmission time of the entire network, which seriously affects the concurrency of the blockchain system.
