Abstract: Disclosed herein are methods and systems to facilitate a blockchain-backed peer-to-peer transaction without requiring the recipient's personally identifiable information and without updating the recipient's blockchain. A central server may receive a transaction request from a sender and may identify a system blockchain associated with the sender. When the server determines that the sender's accounts can satisfy the request, the server generates a unique transaction token. The server then transmits the unique transaction token to the sender, recipient (if indicated within the sender's request), and one or more electronic terminals. When the server receives an indication that the recipient has inputted the unique transaction token to the electronic terminal, the server appends a block instance corresponding to the transaction to the system blockchain.

Abstract: Disclosed herein are methods and systems of visually representing and tracking transactions on a graphical user interface to identify fraudulent or money-laundering entities. A server may receive data corresponding to a plurality of transactions for display on the graphical user interface as a set of graphical nodes linked by a set of graphical components. When the server receives a selection of a graphical node from a user, the server may display on the graphical interface a first subset of graphical nodes directly linked by a first subset of graphical components to the selected graphical node, a visual attribute of each of the first subset of graphical components directly linked to the selected graphical node, and a second subset of graphical nodes indirectly linked by a second subset of graphical components having at least one degree of separation from the selected graphical node.

Abstract: In various embodiments, the present invention is directed to a computer-implemented method for a track data point-of-sale platform. The computer-implemented method comprises receiving a transaction request by a processor configured to process point-of sale transactions. The transaction request comprises at least one parameter associated with a payment instrument configured for use in the point-of-sale transaction. The computer-implemented method further comprises identifying, by the processor, a transaction request type characterized by an identifier in at least one parameter associated with the payment instrument. The computer-implemented method further comprises processing, by the processor, the transaction request, according to the transaction request type. The computer-implemented method further comprises generating, by the processor, a response to the transaction request.
