Abstract

The embodiment of the invention discloses a block chain storage method, system and device and a computer readable storage medium. The method comprises when the data is written, storing user data on ahigh-performance memory, namely a first memory, of a first-layer storage structure through a memory interface; when the storage space of the first memory is full, starting the second memory, mapping the data in the first memory to a corresponding hierarchical tree structure in a low-performance memory, namely a second memory, located in a second layer of storage structure, transferring to a firstmemory for storage; using the block chain node to retrieve the user data; carrying out the retrieval on the first-layer storage structure firstly, if the retrieval is not carried out on the first-layer storage structure, continuing to retrieve on the second-layer storage structure, so that the efficient utilization of underlying hardware resources is achieved, the staged delay caused by global read-write locking is overcome, the storage performance of the block chain is improved, and the method is suitable for scenes with large data storage amount.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a block chain storage method, system, device and computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of cloud computing, big data, Internet of Things, artificial intelligence and other information technologies and the digital transformation of traditional industries, the amount of data has shown geometric growth. According to IDC's prediction, the total amount of global data is expected to reach 44 ZB in 2020, and the amount of data in my country will reach 8060 EB, accounting for 18% of the total global data. [0003] Blockchain storage is a data storage technology that uses the disk space on each machine through the network, and forms these scattered storage resources into a virtual storage device. The data is scattered and stored in every corner of the network, and a user's The data is split into fragments an...
