Abstract: 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.

Abstract: Systems and methods for message transfer and retrieval are provided. According to some aspects, message information is received from a sender, and a message can be created based on the received message information. A hash of the message and transaction information related to the message can be generated and provided to a current block in a blockchain. The message is transferred or otherwise provided to a receiver, and upon receipt and validation of authentication information from the receiver, access to the received message is provided to the receiver. A hash of the received message and additional transaction information related to the received message is generated and provided to a current block in the blockchain. Other aspects also are provided.
