Embodiment Construction

[0049] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0050] Blockchain technology, also known as distributed ledger technology, is a distributed Internet database technology. The network built based on blockchain technology can be called a blockchain network. The blockchain network contains multiple blockchain nodes, each node corresponds to at least one blockchain, and each blockchain contains at least one block . Blockchain technology has the characteristics of decentralization, openness and transparency, non-tampering, and trustworthiness. Therefore, the application field of blockchain technology is becoming more and more extensive.

Abstract

The invention relates to the technical field of block chain, in particular to a data storage method and a system based on the block chain. The method comprises the following steps: a proxy node of a main chain detects whether the available storage capacity of the proxy node is larger than a preset storage threshold; if it is larger than, the agent node of the main chain records the block numbers of all blocks between the starting block and the terminating block to be transferred. The proxy node of the side chain sends all the blocks to the consensus node of the side chain; the agent node of the main chain broadcasts the block transfer information to the whole network after detecting all the blocks in the side chain to pass the consensus verification. Each node in the main chain deletes allthe blocks according to the block transfer information. As the node in the main chain can transfer and store part or all of the blocks in the side chain when the available storage capacity is insufficient, each node in the main chain has more available storage capacity, so that each node in the main chain can store the block data more reliably, and the work reliability of the main chain is improved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a data storage method and system based on blockchain. Background technique [0002] Blockchain technology integrates technologies such as algorithms, mathematics, cryptography, and economic models, and establishes a trust mechanism based on peer-to-peer network relationships, becoming a decentralized system that can operate without relying on mutual trust or relying on a single centralized organization formula system. [0003] Since the blockchain technology needs to store each block, and the latter block needs to record the hash value of the previous block, in this way, a non-tamperable data chain is formed. Therefore, when the number of blocks increases, the block Blockchain technology requires a large available storage capacity to store longer data chains, resulting in insufficient available storage capacity of blockchain nodes and affecting the reliability of the ...
