Course Introduction

Zero Knowledge Proofs are often described as magical. They allow someone to prove that a statement is true without revealing the information that makes it true. For a long time, this idea lived mostly in academic papers and specialist circles. Today, it is becoming a practical foundation for privacy, scalability, and trust in digital systems.

This short course offers a gentle but serious introduction to Zero Knowledge. It is designed for people who are curious about how modern cryptography changes the way trust works online without requiring a background in mathematics or programming. In about 15 minutes of reading, you’ll build a clear intuition for what Zero Knowledge is, why it matters, how it works at a high level, and where it is already being used in the real world.

The course is based on A Friendly Introduction to Zero Knowledge and is created in collaboration with Oskar Thorén - a researcher and engineer working at the intersection of cryptography, privacy, and decentralized systems. Oskar has led and contributed to multiple public-good projects in the Ethereum ecosystem, including Logos, Waku & Vac. He is currently part of the Ethereum Foundation, where he focuses on bringing privacy-preserving technologies to real-world use cases. This course is facilitated by Peter Farbey from Web3Privacy Now.

Rather than teaching formulas or tools, this course focuses on understanding. It is meant to be read slowly, thought about carefully, and used as a foundation for deeper exploration whether you’re interested in privacy, Web3, cryptography, or the future of trust online.
