Abstract

A method for verified data storage via blockchain includes: storing a blockchain comprised of a plurality of blocks, each comprised of a block header and a plurality of transaction values, the block header including a timestamp; receiving a transaction notification including an entity identifier and data values; validating the data values based on a validation notification received from a verifying entity; generating a new block header comprised of a current timestamp, a block reference value, and a transaction reference value, the block reference value being generated via hashing of the block header included in a most recent block based on the timestamp, and the transaction reference value being generated via hashing of new transaction values including the data values; generating a new block comprised of the generated new block header and the new transaction values; and transmitting the new block to a node associated with the blockchain.
