Problems solved by technology

[0003] In the "centralized" data storage and sharing method, the data is uniformly stored on the central node, and the central node has complete authority over the data. Users must have "unlimited trust" in the central node to ensure the credibility of the data. At the same time, if If the central node loses data, users will not be able to obtain the data

Abstract

The embodiment of the invention discloses a data storage and recovery method, device and equipment based on block chain and a medium. The data storage method comprises the following steps of using a block write-in node to send a block write-in request to a plurality of associated nodes, wherein the block write-in request comprises the to-be-written-in information, the first scene description information corresponding to the write-in block and the first block description information; and using the block write-in node to receive the block successful write-in feedback sent by the block generationnode. According to the technical scheme provided by the embodiment of the invention, the effective restoration of the block chain can be realized when the block chain is damaged or lost during transmission, the problem that the data storage and sharing completely depends on a single center is effectively solved, and the data tamper resistance and credibility and the data security are ensured. Compared with an existing data storage mode, the sense of security of the participating users is increased, and the data is more difficult to lose and is safer.

Description

technical field [0001] Embodiments of the present invention relate to information processing technology, and in particular to a blockchain-based data storage and data recovery method, device, device, and storage medium. Background technique [0002] With the continuous development of Internet technology, the data shows a massive increase. Therefore, the requirements for data storage and sharing technology are also constantly improving. At present, the "centralized" data storage method is widely used and common. [0003] In the "centralized" data storage and sharing method, the data is uniformly stored on the central node, and the central node has complete authority over the data. Users must have "unlimited trust" in the central node to ensure the credibility of the data. At the same time, if If the central node loses data, users will not be able to obtain the data. Contents of the invention [0004] Embodiments of the present invention provide a blockchain-based data sto...
