Abstract
A system and method for authenticating data files using a block chain network. An exemplary method includes identifying data files in electronic data storage, computing hash values for files, adding pairs of the hash values and computing hash values for each resulting pair, continuing this process to a root level of a hash tree, and sending the root hash to a blockchain network in which one or more nodes in the blockchain network adds the hash value as one or more blocks in a blockchain.
