Embodiment Construction

[0041] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided for more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] In a distributed storage system based on blockchain technology, for example, in a distributed storage system based on alliance chains, some nodes have idle storage space, which can be used to provide storage for other users with storage needs Serve, that is, become a storage node, so as to obtain certain benefits. For example, a user publishes a file storage requirement and broadcasts it through the entire network of the blo...

Abstract

The invention discloses a data holding proving method and device and a readable storage medium, and belongs to the technical field of internet. The method includes the steps that challenging data, corresponding to a target file, sent by a second node is received by a first node and includes a feature value of the target file and a first random number meeting preset conditions; then, according to the feature value and the first random number, a corresponding fragment in the target file is searched for, and the found fragment is used as a target fragment; according to the target fragment and a preset one-way function, proving data corresponding to a verifying value of the target file is obtained and sent to the second node to be used as a work amount proof of the first node. In this way, thesecond node can verify whether the first node holds the target file or not according to the proving data and the verifying value of the target file to prevent cheating of work amount existing in storage nodes in a block chain system.

Description

technical field [0001] The present invention relates to the technical field of the Internet, in particular to a method, device and readable storage medium for proving data possession. Background technique [0002] In the information age, data storage is crucial. Currently, data storage methods are mainly divided into local storage and cloud storage. Cloud storage is a centralized service, and the service party controls the rules and dominance. Once the service party stops the service, the stored data will not be available. In addition, cloud storage services are provided through the construction of professional data centers, and the cost is extremely high. In the commercial field, the company's big data optical storage costs are not a small expense. Based on this, some researchers proposed a shared storage network based on blockchain technology. Blockchain and sharing economy are both current hot spots and leading future trends. As the amount of information increases, mo...
