Problems solved by technology

It can be seen that in the prior art, when backing up block 1, each node in the blockchain network needs to save a complete business block, and the storage resources of each node are extremely occupied
Moreover, block 1 of node 1 is transparent to all nodes in the blockchain network, which also results in block 1 of node 1 having no privacy for other nodes

Embodiment Construction

[0079] The technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Apparently, the described embodiments are only some of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0080] This application also relates to related technologies of blockchain. Among them, blockchain is a new application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain (Blockchain), essentially a decentralized database, is a series of data blocks associated with each other using cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify its Validity of information (ant...

Abstract

The invention discloses a data processing method and device for a block chain network, computer equipment and a medium, and the method comprises the steps that the block chain network comprises a first consensus sub-network with a first main node and K second consensus sub-networks with second main nodes, and the first main node performs consensus on the service block in a consensus main network comprising the first main node and the second main node; the method also includes partitioning the service block to obtain M block partitioning data and N block redundant data, the association set comprising M + N pieces of block association data, and one piece of block association data being block partitioning data or block redundant data; and sending the block association data of the association set to the second main node, so that the second main node uplinks the obtained block association data after passing the consensus of the service block, wherein the uplinked block association data is used for backing up and restoring the service block. By adopting the invention, the occupation of storage resources when the service block is backed up and restored can be reduced, and the privacy of the service block is improved.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a data processing method, device, computer equipment and media of a blockchain network. 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. Blockchain (Blockchain), essentially a decentralized database, is a series of data blocks associated with each other using cryptographic methods. Each data block contains a batch of network transaction information, which is used to verify its Validity of information (anti-counterfeiting) and generation of the next block. [0003] In existing applications, blocks on the blockchain can be backed up. The backup method is usually: if node 1 needs to back up its own block 1 in the blockchain network, the node can Block 1 is sent to other nodes in the blockchain network, and other ...
