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.
The Cardano Vision 2026 proposal builds on this momentum and contains 15 programs organized into six clusters, each aligned to measurable ecosystem outcomes.
The expected outcome will be a structured research and innovation pipeline delivering 42 outputs that systematically translate foundational research into deployable capabilities and measurable ecosystem impact.
The outcome will also be five Cardano Improvement Proposals (CIPs) progressing to implementation readiness, including in the strategic focus areas of identity services, ZK-enabled Layer 2 scalability, and post-quantum security.
Post-quantum readiness increases
The market is increasing its preparation toward quantum readiness following Google’s quantum computing research update in late March.
The research suggested that the post-quantum transition can’t be postponed any longer, indicating that Bitcoin’s elliptic-curve cryptography could be broken with about 500,000 qubits, far fewer than older estimates, but such machines do not yet exist.
Google’s Quantum AI team indicated that quantum computers could break the elliptic‑curve cryptography used by Bitcoin and other major cryptocurrencies, with fewer than 500,000 quantum qubits, which is significantly less than previously estimated. This prompted some analysts to give 2029 as a potential deadline for Bitcoin and the broader blockchain ecosystem to strengthen their defenses.
