In this episode, the host reflects on the journey of the Zero Knowledge podcast and the growth of the ZK community. They discuss finding a bug in the sprout version of Zcash and the consequences of a Zcash hack. The chapter also explores the changes in the podcast, reflects on past episodes, and touches on various topics covered, including teaching Zero Knowledge Proofs and upcoming topics like hardware and data availability.

Anna chats with Alex Gluchowski, CEO of Matter Labs & co-creator of zkSync network. They discuss recent initiatives like ZK Stack, Hyperchains, ZK Credo mission statement, and the upcoming Boojum proof system upgrade. They explore challenges in building zkSync, decentralization, bridge projects, and utilizing Ethereum blockchain for data security. They delve into hyperchains, language implementation, the popularity of zkSync, and its future vision.

CTO Brandon Kase and Head of Product Steve Pack from O(1)Labs discuss developments in the Mina Protocol, insights into the zkApps building environment, and the technical aspects of o1js. They also explore potential applications of zero-knowledge proofs and the industry shift toward a builder-centric approach.

In this week’s episode, Anna and Nico interview Or Sattath, Assistant Professor at the Ben-Gurion University in the Computer Science department. This is the 2nd episode with Or on this show, continuing the conversation around Quantum Cryptography. This time, he describes how we can transition from a pre-quantum to a post-quantum environment, looking at existing systems like Bitcoin and Ethereum. He covers why the methods used in the transition will be important, techniques on how this could be executed and the challenges in designing these techniques and the complications that can arise. Finally, they go on to discuss Quantum Money and recent works in this area.Here’s some additional links for this episode:Part 1 - Episode 288: Quantum Cryptography with Or Sattath Polynomial-Time Algorithms for Prime Factorization and Discrete Logarithms on a Quantum Computer by Shor Shor’s Algorithm Grover’s Algorithm A fast quantum mechanical algorithm for database search by Grover Fawkescoin: A cryptocurrency without public-key cryptography by Bonneau and Miller Bitcoin is not quantum-safe, and how we can fix it when needed by ButerinCryptographic canaries and backups by Justin Drake Notes and recommended links by Or Sattath:NIST post-quantum standardization for post-quantum digital signatures and public-key encryption (or, more precisely, Key Encapsulation Mechanism, KEM). These are classical schemes that, unlike almost all the existing schemes that are used in practice, are secure against quantum adversaries.Signature Lifting (arXiv link) is discussed as a technique to migrate to post-quantum signatures, especially for those who didn't prepare in advance. Here's a recommended Twitter thread summarizing the results by Shai Wyborski, Or’s co-author.An approach to upgrade Bitcoin to quantum money is available here. This uses a cryptographic primitive which is called quantum lightning, which was introduced here.Some smart contacts capabilities can be supported as well. This construction is based on one-shot signatures, which isdiscussed in some detail during the interview. The bottom line of this work is that we can have the most important utility that Bitcoin provides, without the need for a blockchain, or any other consensus mechanism. Uncloneable cryptography was discussed during the interview. Quantum encryption with certified deletion was discussed as an interesting example of a property that can be achieved only in quantum cryptography.Applications are now open to attend zkHack Istanbul - Nov 10-12!
