Hoskinson Explains Hash vs Lattice-Based Cryptography
Charles Hoskinson Weighs Hash-Based vs Lattice-Based Cryptography as NIST Advances Post-Quantum Standards
Cardano founder Charles Hoskinson recently drew attention to a growing security discussion in crypto: how today’s cryptography should evolve to remain secure in a future where quantum computers could weaken widely used public-key systems.
The broader context is a major shift underway in the cybersecurity world. The US National Institute of Standards and Technology (NIST) has begun standardizing so-called post-quantum cryptography—algorithms designed to resist attacks from quantum computers.
Two of the first NIST-standardized post-quantum algorithms are CRYSTALS-Kyber and CRYSTALS-Dilithium. Both are lattice-based cryptographic constructions, a family of techniques built on mathematical problems that are believed to remain difficult even for quantum machines.
Lattice-based systems are relevant to crypto networks because public-key cryptography underpins core functions such as address ownership, digital signatures, and secure communications. As NIST moves from research to standards, projects evaluating “quantum-resistant” upgrades increasingly use these algorithms as reference points for what may be deployable at scale.
The post-quantum landscape is not limited to lattices. Other approaches have been studied and proposed, including multivariate schemes such as the Rainbow (Unbalanced Oil and Vinegar) construction, which is based on the difficulty of solving systems of multivariate equations. Hoskinson’s comments were framed within this wider debate over which cryptographic families—such as hash-based and lattice-based—are best suited for long-term security and real-world deployment.
- What happened: Hoskinson highlighted the trade-offs between cryptographic approaches as post-quantum standards take shape.
- Why it matters: Quantum-resistant cryptography affects how blockchains may secure signatures and key ownership in the long run.
- Broader context: NIST’s early post-quantum standards, including Kyber and Dilithium, are shaping the shortlist of algorithms considered practical for future upgrades.
