System and methods for compressing data for use in a distributed ledger are provided. In one form, the system includes: a network interface; a user interface device; and a control circuit coupled to the network interface and the user interface device. In this form, the control circuit executes a data compression module configured to: receive, via the network interface, a data set; transform and store the data set into a file format of rows and columns in which data of the data set are stored in a columnar fashion; apply a first compression step to compress each row and write each compressed row into the file format; apply a second compression step to further compress data after the compressed rows have been written into the file format; and encode the compressed data and transmit the encoded data to a first node of a distributed ledger.
