Quantum computers could undermine cryptographic systems and electronic communication. Even though current quantum machines contain just a few dozen qubits, and it is challenging to predict all future quantum applications, cryptographers must prepare for a future when quantum computers will break public-key cryptography.

In this talk we will investigate post-quantum constructions of zero-knowledge proofs and focus on their lattice—based and hash-based candidates. Zero-knowledge proofs represent an important cryptographic tool which is crucial for many applications in the blockchain. We will discuss the challenges of their post-quantum constructions and look into the applications to privacy-preserving cryptocurrencies.
