Distributed storage data optimization method based on block chain technology

Abstract

The invention discloses a distributed storage data optimization method based on a block chain technology, and belongs to the block chain technology field, when the block node receives the new data, adaptive conversion is performed on the new data in advance to be compatible with a system of the block node; then, the original data is uploaded to the cloud for backup through a local area network inthe conversion optimizer; the converted data is stored into a scanning area on the block node; the scanning area scans the converted data; scanning results are arranged according to repetition frequency; a comparison area is entered; the high-frequency repeated data in the historical data is compared with the high-frequency repeated data in the comparison area one by one according to an arrangement sequence; after comparison succeeds, repeated data is intercepted from the converted data, interception position information is recorded, the intercepted converted data is subjected to conventionalcompression processing and stored in a database, then the interception position information is dynamically encrypted and imported into a conversion optimizer, and then encryption information is automatically deleted, so that the data redundancy is greatly reduced.

Description

technical field [0001] The present invention relates to the field of block chain technology, and more specifically, relates to a distributed storage data optimization method based on block chain technology. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Based on these characteristics, blockchain technology has laid a solid "trust" foundation, created a reliable "cooperation" mechanism, and has broad application prospects. [0003] 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) is an important concept of Bitcoin. It is essentially a decentralized database. A...

[0004] Therefore, with the continuous development of the blockchain, the more blocks there are, the more data there will be on the blockchain, which puts forward high requirements on the data storage and computing capabilities of the blocks, especially for full nodes. It is necessary to store all the data on the blockchain, so the system load caused by massive data is very huge. Most of the existing solutions use discarding expired data or other methods, but on the one hand, the effect is not good, and the reduction of expired data often cannot keep up with new ones. The birth of data, on the other hand, expired data is difficult to determine, and there is a possibility of later needs. This method of permanently losing data integrity is not advisable, and the system architecture on different blocks is different, which is inevitable in the process of data conversion and use. There will be losses or even new data, further increasing the pressure on data storage
