A method for conveying a data message using a public ledger includes: generating, by a generation module of a processing server, a data message, wherein the data message comprises one or more data values; electronically transmitting, by a transmitting device of the processing server, a data signal superimposed with the generated data message to a first computing system; receiving, by a receiving device of the processing server, a data signal superimposed with an encrypted message from the first computing system, wherein the encrypted message is generated via application of one or more encryption algorithms to the generated data message using at least one encryption key; appending, by the generation module of the processing server, an identification value to the encrypted message; and submitting, by the transmitting device of the processing server, the appended encrypted message to a public ledger associated with a second computing system.
