Episode 145: Circom & Hermez with Jordi Baylina

In this week's episode, Anna and Fredrik catch up with Jordi Baylina, co-founder of Iden3, the creator of Circom & SnarkJS. They chat about his work in the ecosystem, building zk circuits and the recently announced Hermez, a new zkrollup with a novel proof-of-donation mechanism that will redistribute 40% of earnings to Ethereum-based community projects.

Jordi has an amazing story, which we got to explore in this episode, so thanks again Jordi for being on the show!

Thank you to this week's sponsor Parity Technologies

Parity is currently looking to fill a number of job positions including many on the engineering side.

As an engineer at Parity, you would get to write Rust all day, be at the forefront of creating and shaping the decentralized web and hopefully also dig into some cool zero knowledge crypto tech! The best way to get noticed for this role is to familiarise yourself with Substrate – the platform built by Parity to make building blockchains much much easier. So go check out the substrate libraries and then head over to parity.io/jobs to find out more

Thanks again Parity for sponsoring this episode!
