Cardano 2026 Research Plan Targets Post-Quantum Security, Leios and Implementation-Ready CIPs

Cardano Post-Quantum Security Becomes a Core Research Priority

IO Research’s Cardano 2026 funding request was presented during an X Space featuring Charles Hoskinson, Agalos Kiayias and members of the IO Research team. The discussion placed post-quantum security, Ouroboros Leios, Peras, developer experience and implementation-ready research outputs at the center of Cardano’s next infrastructure phase.

The largest security theme is Cardano’s path toward post-quantum readiness. Agalos explained that quantum computers create a specific challenge for blockchain systems because they could threaten the cryptographic assumptions that protect signatures, consensus and long-term asset security. In a blockchain context, security is not only about protecting a single communication session. It is about preserving transaction history and encoded value over long periods of time.

That matters especially for proof-of-stake networks. Cardano uses cryptography not only for basic signatures, but also for more advanced components that support consensus and network security. During the Space, verifiable random functions and key-evolving signatures were mentioned as examples of cryptographic primitives that need to be assessed in a post-quantum setting.

The work treats post-quantum security as a system-wide research challenge, not as a simple replacement of one signature scheme with another. It involves cryptographic primitives, migration strategies, performance impact, network design, incentives and compatibility with Cardano’s existing architecture. Charles also added a broader security argument, saying that AI could lower the cost of attacking complex systems by making protocol analysis and code review more accessible to adversaries.

For Cardano, the practical goal is to prepare a multi-year path toward quantum-resistant infrastructure. That includes evaluating approaches such as hash-based and lattice-based cryptography, understanding their trade-offs and setting a technical direction before quantum risk becomes an operational problem for the wider blockchain industry.

Leios and Peras Frame Cardano Scaling Without Weakening Decentralization

A second major part of the plan focuses on scalability and execution. Agalos framed the challenge clearly: increasing throughput is easier if a network is willing to compromise security or decentralization. The harder task is scaling while preserving Cardano’s security model, permissionless structure and predictable operation under pressure.

This is where Leios and Peras become central. They were not presented only as scaling upgrades, but as part of a broader Ouroboros protocol stack. The goal is to combine higher throughput, faster settlement characteristics and the preservation of properties Cardano considers fundamental, including decentralization and the network’s self-healing behavior.

Self-healing was highlighted as an important part of Cardano’s architecture. When a network runs reliably for years, users often do not see how much design is required for a system to respond to stress without centralized intervention, manual history resets or permanent damage to trust. Leios and Peras are positioned as research directions that try to extend that logic into a higher-demand environment.

The funding request also includes congestion control. Even a more scalable blockchain can face sudden spikes in demand. In those moments, it is not enough for the network to remain online. The system must decide how resources are prioritized, how applications retain utility and how user experience is protected during heavy traffic.

The third layer is human-centered design and multi-resource consensus. During the Space, the team discussed the idea that Cardano could eventually recognize contribution to the network beyond stake alone. One example involved users who provide computing resources to help create proofs for bridges to other systems. Through future research, that useful work could become part of a broader security and consensus model.

IO Research Links Papers, Prototypes and CIPs to Implementation

The delivery model is the most important part of the governance discussion. The treasury decision is not only about funding academic research. It is about funding a process that moves research outputs closer to implementation.

According to the discussion, the Cardano Vision 26 request is $7.9 million. Last year’s request was $13.4 million, which the team described as a reduction of about 40%. The plan covers 36 FTEs, with roughly $4.2 million allocated to research and $3.7 million allocated to applied research.

The structure includes six technical work packages and a seventh package for project management, communication and dissemination. The technical areas cover trust and security, scalability and execution, developer experience, application adoption, economic systems and governance or social infrastructure.

The key shift is the type of output being targeted. IO Research and the applied research team are not aiming to deliver only peer-reviewed papers. The expected outputs include technical reports, prototypes, Cardano problem statements and Cardano Improvement Proposals. The team cited 5 Cardano Improvement Proposals, 12 prototypes and 8 Cardano problem statements as planned deliverables.

That changes the weight of the vote. If research remains only academic, the community has a harder time measuring its practical value. If research becomes technical reports, prototypes and CIPs that independent teams can pick up, treasury funding supports a pipeline from theory toward implementation.

Nicholas from the applied research team explained that recent work has focused on moving faster from research results to engineering. The goal is to make outputs understandable and useful for teams outside Input Output, including developers who can work with specifications, test prototypes or participate in implementation. During the discussion, teams such as BlinkLabs, Amaru, Harmonic and other Cardano developers were mentioned as examples of the broader ecosystem that could benefit from implementation-ready outputs.

For Cardano governance, this funding request is ultimately a decision about future technical capacity. It asks whether the treasury should support a security and scaling pipeline before quantum risk, heavier network demand and implementation bottlenecks become more expensive problems. If funded, the work will be judged less by how much research it produces and more by whether those outputs become usable specifications, prototypes and CIPs that Cardano builders can move into real infrastructure.
