Abstract: 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.

Abstract: Methods and systems for controlled data sharing are provided. A method includes: communicating, as a first node of a supply chain distributed ledger, with a second node and a third node of the ledger, the nodes corresponding to a first entity, a second entity, and a third entity in a supply chain; storing, with a data management module, a hash of a public version of a contract between the first entity and the second entity; replicating the hash of the public version of the contract to the ledger; sharing a private version of the contract between the first and second nodes; storing a hash of a public version of a purchase order between the first entity and the third entity; replicating the hash of the public version of the purchase order to the ledger; and sharing a private version of the purchase order between the first and third nodes.

Abstract: Methods and systems for invoice adjustment are provided. A method for generating adjustments includes: accessing, by an invoice adjustment module, contents of a contract, the contract being of a purchaser for transport of goods by a carrier; receiving shipment events data regarding transport of the goods by the carrier that result in a change or addition in transportation charges; calculating an adjustment to the price based on the shipment events data; generating an invoice for transport of the goods including the adjusted calculation to the price; and adding the invoice to a supply chain distributed ledger via a network interface, the supply chain distributed ledger comprising a plurality of nodes, at least one node corresponding to the purchaser and at least one node corresponding to the carrier, the invoice being accessible on the supply chain distributed ledger to the purchaser and to the carrier.

Abstract: Method and system for product certification management are provided.
