Abstract
A system and method provided for verifying data integrity for large volumes of critical data using blockchain technology. An exemplary method includes storing data files in electronic storage; creating a hash values for of each of the files; and transmitting the hash values to a blockchain network in which one or more nodes in the blockchain network adds the first hash values as blocks to the blockchain. Moreover, an API is provided to monitor data operations performed on the data files and transmit metadata of any operations performed to a transaction log. In turn, hash values relating to the data operations are also created and transmitted to the blockchain network to be added as additional blocks in the blockchain, such that the blockchain can be used to verify the accuracy of the data files stored on the electronic storage.
