This patent protects many fundamental aspects of offline payments. The basic scope is that the transaction is digitally signed by the payer and transmitted locally to the payee as a token providing the payee with a digitally signed commitment. When any of the parties gets online access, the transaction, stored by both parties, is communicated to the back-end ledger independently of each other. 


This patent application has previously received a positive International Preliminary Report on Patentability and it is now in the process of being nationalized in the US, Europe, India, China, and Taiwan.


” It is extremely pleasing that our first and very fundamental Digital Cash patent application for offline payments is now granted in the US. This is strategically important for several reasons; the patent application has an early priority date January 2020, a very wide scope that protects many technical aspects and we expect that our many other Digital Cash patent applications may also later be granted in other jurisdictions”, says Joachim Samuelsson, CEO of Crunchfish.
