Cardano builder Input Output Group has revealed a new research proposal projected to boost Cardano’s quantum readiness.

In a tweet, Input Output stated that the IO Research proposal future-proofs Cardano and builds long-term resilience for post-quantum security.

IO noted that the quantum threat represents a long-term reality, with the time to prepare being not later but now. It noted that layer by layer, Cardano is being hardened.

Three strategic themes underpin Input Output’s proposal for the Cardano ecosystem, which includes human-centered design, scalable architecture, and post-quantum security. Scalability will be addressed through a layered approach, combining consensus improvements such as Leios and Peras, and execution scaling such as L2s and data availability ZK-enabled scaling, including ZK rollups.

Post-quantum security ensures long-term resilience as cryptographic assumptions evolve, with proactive evaluation and migration planning for quantum-resistant primitives.
