Zero-knowledge proofs promise privacy-preserving Web3, but they often feel intimidating and hard to use in practice. In this talk, we’ll explore o1js, an open-source TypeScript SDK for building zero-knowledge applications (zkApps) without needing a cryptography background. I’ll walk through the core concepts, what a zkApp looks like in code, and how proofs fit into a typical dApp architecture, so you leave with both an intuition for when to use zk and a concrete starting point to try o1js yourself.
