Problems solved by technology

At the same time, when a new full node joins the network, it needs to synchronize data with peer nodes in the network. Such synchronization will become unstable due to network conditions, the synchronization time is unpredictable, and a large amount of network bandwidth will be consumed to complete the synchronization.

Embodiment Construction

[0037] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0038] In order to solve the problem of a large amount of data stored in the block chain of the whole node, the embodiment of the present invention uses a distributed storage method, and multiple nodes coordinate the storage processing of the block chain, and the blocks in the entire block chain are stored in a decentralized manner. on each node.

[0039] see figure 1 , is a schematic structural diagram of a blockchain network according to an embodiment of the present invention. The block chain network 100 includes: a plurality of nodes 101 . Every P2P network node that participates in transactions, block storage, block verification or forwarding, etc. can be...

Abstract

The present invention discloses a blockchain storage method and device and a node device. The method comprises the steps of adding in a virtual cluster by accepting a cluster establishing invitation or sending the cluster establishing invitation, wherein the virtual cluster comprises a preset number of nodes; according to a preset first block distribution rule, storing a or a plurality of blocks in a blockchain to enable the blocks stored in the nodes in the virtual cluster can form a complete blockchain. According to the present invention, by respectively storing the blocks in the blockchain in the nodes of the virtual cluster redundantly, the memory space of the nodes is reduced; each block is stored redundantly, the storage safety can be guaranteed; the block synchronization speed is improved, and the query efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain storage method, device and node equipment. Background technique [0002] At present, blockchain technology is being applied more and more widely. Whether it is currency, virtual items, real estate, stocks, etc., they are all trying to use blockchain to record, making transactions transparent and decentralized. [0003] The blockchain network is based on a P2P (Peer to Peer, peer-to-peer network) network, and each P2P network node participating in transactions, block storage, block verification or forwarding is a node in a blockchain network. The data exchange between nodes is verified by digital signature technology, without mutual trust, as long as it is carried out in accordance with the established rules of the system, nodes cannot and cannot deceive other nodes. [0004] Since all transactions are stored in the blockchain, with the increase of tran...
