In an era of rapid advancements in quantum computing, the global financial ecosystem faces a future where today’s encryption standards may no longer be sufficient. Quantum technologies bring new security risks that could undermine current cryptographic protections. In response, Project Leap 2 represents a pivotal step forward in enhancing the resilience and security of payment infrastructures worldwide.
As Nexi we are proud to be part of Project Leap 2, a collaboration between the BIS Innovation Hub, Bank of Italy, Bank of France, Deutsche Bundesbank, Nexi–Colt, and Swift, successfully demonstrated the integration of quantum-resistant cryptography into a live payment system.
The initiative tested the integration of post-quantum cryptography (PQC) into an operational payment system by replacing traditional digital signatures with quantum-resistant algorithms during liquidity transfers. This required updates and adjustments across several system components to ensure full compatibility
The project’s findings highlight key considerations for transitioning to quantum-safe security, including performance differences between traditional and PQC algorithms, interoperability challenges, and the need for strong governance and organisational readiness.
Project Leap Phase 2 confirms that migrating payment systems to quantum-resistant solutions is a complex but essential step. Early preparation and coordinated collaboration across institutions will be crucial to safeguard the resilience of the financial ecosystem.
