Jordi Baylina
Jordi Baylina is a veteran Ethereum developer and one of the foundational figures in zero knowledge technology. He co-founded Iden3 and created Circom and SnarkJS, open source tools that became standard infrastructure for building zk circuits and went on to power projects including Tornado Cash and Semaphore. He later served as technical lead of Hermez, an Ethereum zk-rollup, and when Hermez merged with Polygon in 2021 he became technical lead of Polygon zkEVM, which launched on mainnet in March 2023. A fixture of the Ethereum community since its earliest days, he remains a frequent guest on podcasts tracing the evolution of Layer 2 scaling.
