Why are payments dependent on online services?

It is very convenient to pay digitally. But societies becomes vulnerable when they are dependent on online services. This is an unnecessary risk to take.

Crunchfish Digital Cash provides payment resilience by
allowing users to pay offline.

Balancing security and scalability

Crunchfish strikes the perfect balance between security and scalability with its Digital Cash solution. The level of security must be increased as offline payments cannot rely on the backend security when making and storing offline payments. For scalability, it is important to be able to deploy and upgrade the offline payment solution on all devices on which the underlying payment application is available. Crunchfish Digital Cash augments either CBDC systems or commercial payment applications.

Enabling transaction privacy or anonymity

Crunchfish Digital Cash can enable transaction privacy and anonymity while maintaining financial system integrity for both online and offline payments. In case of transaction privacy the identity of the payer is only visible to selected parties, for instance the payer’s bank, whereas transaction anonymity means that the payer’s identity is not visible to anyone. If a financial regulator allows transaction anonymity, rather than just transaction privacy, this can also be supported by the Crunchfish Digital Cash solution.
