A blockchain information transmission method and system based on satellite-ground collaboration

Abstract

The present invention provides a block chain information transmission method and system based on satellite-ground collaboration. The method includes: the block chain core node receives the to-be-transmitted information sent by the block chain node, and verifies the to-be-transmitted information; After passing, the information to be transmitted is sent to the communication satellite; the communication satellite receives the information to be transmitted, and broadcasts the information to be transmitted to each block chain node and block chain core node through a wireless channel, so that each block chain node and block chain The core node processes the stored blockchain according to the information to be transmitted. The present invention simultaneously broadcasts information to each block chain node by using communication satellites, avoids the point-to-point transmission in the P2P broadcast scheme, improves the information transmission efficiency of the block chain, reduces the synchronization time of the entire network nodes, and improves the block chain system. transaction efficiency.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a blockchain information transmission method and system based on satellite-ground collaboration. Background technique [0002] Blockchain is a distributed digital ledger system, which has the characteristics of distributed storage, decentralization, password 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 proof of work, proof of equity, and proof of share authorization. Taking the consensus algorithm using proof-of-work as an example, since the entire blockchain is stored on each node, if an ...

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.
