A decentralized distributed data storage method and device in a blockchain network
Technical Field The present invention relates to the technical field of blockchain data storage, in particular, a decentralized distributed data storage method and device. BACKGROUND OF THE INVENTION [0002] In this information age, data is everywhere. It has almost become the basis of our modern life and work. However, with the development of information, some negative events accompanying it are also endless, such as professional trafficking in user privacy. Bad data service providers, hacker groups that specialize in stealing user data on major information platforms, and so on. In the face of such a data crisis, there are many solutions to protect data security, such as encrypted storage, and custodial storage; in the encrypted storage solution, because the data is not leaked, it depends on the private key. The private key is not leaked, and the private key comes from the service provider. The process of providing the private key service by the service provider strictly ensures that the private key is not leaked. This is a new data security issue; in the data custody storage solution, the security of the data depends on the custody The technical strength and moral quality of the custodian, and the frequent data leakage incidents of the data custodial platform have gradually reduced people’s trust in the custodian’s technical strength, and the occasional issue of the custodian’s guarding and stealing has made people’s worries even worse. Although various data leakage incidents continue, people still continue to use these services. The main reason behind it is that individuals cannot provide such large-capacity storage capabilities, and individuals cannot maintain a data service device that can provide services anytime, anywhere. So how to provide a storage solution that does not require personal maintenance, does not require third-party hosting, and can provide a large-scale storage capacity has become an urgent problem to be solved.
