This whitepaper discusses two pre-mature design decisions on form for retail CBDC systems that has negative consequences on function. First, the assumption of representing retail CBDC as a digital banknote. A layer-2 approach which improves privacy and has better ability to pay with exact amounts is discussed in the whitepaper. The second example of pre-mature assumptions on form relates to hardware-based secure elements. The whitepaper discusses trusted client applications in virtual secure elements as a better form for implementing the retail CBDC function. Find the whitepaper on this link.

This Crunchfish whitepaper is also published today on pages 12-15 in Currency Research bulletin Central Bank Payment News, July 2024 edition.

“Crunchfish argued early that it is not ideal to implement retail CBDC for offline payments in the form of a digital banknote. We also believe in delivering trust in mobile devices for offline payments by means of virtual secure elements, in contrast to using hardware-based secure elements. I believe Crunchfish will be proven right on both counts", says Joachim Samuelsson, Crunchfish’s CEO.
