ZK in Sui & zkAt with Kostas Kryptos

Zero Knowledge

In this episode, Anna Rose and Tarun Chitra catch up with Kostas Kryptos from Mysten Labs to explore the latest ZK innovations being built on Sui. Kostas shares updates on zkLogin and introduces zkAt (ZK Authenticator), a new research project enabling programmable and updatable access control for accounts where Groth16's trusted setup and the generated toxic waste is used in a very novel way. This discussion also covers Sui's ambitious plans to become quantum-ready, including their innovative approach to transitioning existing EdDSA accounts to post-quantum security using STARKs without requiring users to change their addresses. They touch on ZK Tunnels, working with the Greek stock market, and how ZK is breaking out of the web2/web3 paradigm. Related links:
