  • Venue: Room 204, Courtyard No.5, Jingyuan


Enabling one party to prove the authenticity of a statement to another party without revealing any additional information, zero-knowledge proofs have emerged as a captivating topic within cryptography lately. Over the years, research on ZKP proofs have evolved from theoretical to practical tools with profound implications across various fields. In this talk, we will delve into the exciting realm of zero-knowledge proofs, exploring their fundamental concepts and applications.

The speaker will provide an overview of zero-knowledge, highlighting their role as building blocks of cryptographic primitives to enhancing efficiency, security and privacy and scalability of digital systems. We will journey through the cryptographic landscape, covering classic zero-knowledge protocols and their limitations, setting the stage for recent breakthroughs.

This talk will showcase cutting-edge advancements that have redefined the possibilities of zero-knowledge proofs. From post-quantum secure constructions to succinct non-interactive arguments, we will explore the latest techniques that have expanded the scope and efficiency of these proofs. Additionally, we will discuss their integration with blockchain technology, secure computation, and identity systems, as well as other recent applications.
