The invention discloses a block chain-based data transmission method, device, and block chain system. Two types of nodes are determined from all computer nodes corresponding to the block chain: retrieval nodes and nodes to be stored. The retrieval nodes are slave nodes The nodes that meet the preset conditions determined in all computer nodes corresponding to the block chain; the nodes to be stored are nodes whose remaining storage capacity determined from all computer nodes corresponding to the block chain is greater than the preset remaining storage threshold. The retrieval node obtains the data to be transmitted from the user node, then determines the target storage node from the multiple storage nodes, and stores the data to be transmitted in the target storage node. The present invention determines the nodes whose remaining storage capacity is greater than the preset remaining storage threshold to store data, and selects the retrieval nodes that meet the preset conditions to transfer the data, which can make more reasonable use of the functions and storage space of the corresponding computer nodes in the blockchain , to avoid waste of storage space resources of nodes.
Description
technical field [0001] The present invention relates to the field of communication technology, and in particular to a block chain-based data transmission method, device, and block chain system. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. [0003] In a narrow sense, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. [0004] Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming a...
