Cardano Vision 2026 R&D Session Details Post-Quantum Security, Sharding and ZK Scaling Plan

Input Output Research used its first Cardano R&D session of 2026 to present the structure behind the Cardano Vision 2026 treasury proposal, a 32.916 million ADA request that remains active ahead of its June 8 expiration.

The session focused on what the proposal would fund, including post-quantum cryptography, consensus, sharding, identity, zero-knowledge verification and governance-related work. The presentation added detail to a proposal already under discussion across the Cardano governance process, where DReps and stake delegators are evaluating the size, structure and expected outputs of the request.

Cardano Vision 2026 Defines Six Work Packages

Cardano Vision 2026 is organized around six work packages: trust and security, scalability and execution, developer experience, applications, economics and incentives, and governance and identity.

Input Output Research said the 2026 program follows its previous research effort, which it said delivered 24 papers and eight technology validation outputs. The new structure reduces the previous nine focus areas and 34 work streams into 15 market-oriented programs under the six work packages.

The session described the program as a research and technology validation pipeline. Planned outputs include scientific papers, technical reports, prototypes, formal specifications and Cardano Improvement Proposal material that could later be used by engineering teams.

Post-Quantum Security Becomes a Core Cardano Priority

Post-quantum security was one of the main subjects of the session. Researchers explained that Cardano, like many blockchain systems, relies on cryptographic primitives based on elliptic curve cryptography, while future large-scale quantum computers could affect those foundations.

The proposed work includes assessing post-quantum primitives, developing alternatives for signatures and key-evolving signatures, researching post-quantum verifiable random functions and preparing a migration roadmap for Cardano.

Researchers also discussed a possible post-quantum version of Ouroboros. That work would include security proofs, prototype implementation, formal specification reports and performance benchmarks. The presentation described post-quantum migration as a system-wide topic involving signatures, VRFs, zero-knowledge systems, hardware security modules, congestion control and cross-chain coordination.

Sharding, Identity and ZK Verification Broaden the Agenda

The session also addressed sharding as an exploratory scalability topic. Researchers said the 2026 work is designed to study whether Cardano needs sharding alongside Leios, Hydra, Layer 2 systems and zero-knowledge verification, rather than to move directly into implementation.

Identity was presented as another early-stage research area. The session highlighted work connected to proof of personhood and relationship credentials, including a proposal selected from the University of California, Berkeley. The research is aimed at identity models that can operate inside decentralized blockchain systems and support future use cases around credentials, trust and on-chain interaction.

Zero-knowledge verification was presented as part of Cardano’s scaling and interoperability work. Researchers discussed tooling around Groth16, Plonk, Halo 2, Starks and proof systems that could support bridges, Bitcoin DeFi, Hydra-related applications and future cross-chain systems.

The R&D session added new detail to the Cardano Vision 2026 discussion before the June 8 governance deadline. Voters are now evaluating a 32.916 million ADA treasury request that covers post-quantum security, scaling, identity, zero-knowledge verification and governance research across multiple work packages.
