Systems and Methods for Distributed Data Storage and Delivery Using Blockchain

摘要

In one aspect, the present disclosure provides a system and method for distributed data storage and delivery using blockchain. For example, a file can be received from a participant and split into constituent files. A hash value for the received file and each of the constituent files can be generated, and the constituent files can be encrypted using one or more predetermined or user selected encryption keys. The encrypted files can be stored in at least one storage location. Upon receiving a file retrieval request, each file of the plurality of encrypted files can be retrieved and decrypted using the one or more predetermined or user selected encryption keys. A hash value for each decrypted file can be generated and compared to hash values for the corresponding files of the plurality of constituent files, or a hash value for the recombined constituent files can be generated and compared to the hash value for the original file. Other aspects also are described.
