Mobile payment networks play a critical role in modern digital economies. However, their reliance on uninterrupted network connectivity and backend server availability expose vulnerabilities to payment service disruptions, such as loss of connectivity, overloaded networks, or backend infrastructure failures. These vulnerabilities result typically in transaction failures, negatively affecting both end-users and merchants. To address these challenges, Crunchfish proposes a packet-switched layer-2 approach with offline wallet and terminal modules that bring resilence, privacy, and many other key design objectives of next-generation payment systems.

The future of digital payments hinges on balancing cost, resilience, and seamless integration, bridging traditional infrastructure gaps while gearing solutions for next-generation financial landscapes. This whitepaper has shown a viable way forward with a novel packet-switched architecture delivered by the modular Crunchfish Digital Cash Layer-2 Solution that augments any Layer-1 payment network with multiple desired design objectives.
