Today's guest is Jordi Baylina, who leads the technical team building the Polygon zkEVM. The polygon zkEVM launches in late march, and this episode will serve as your technical introduction to how the zkEVM works.
We got deep into how Jordi & the team pulled this off - we talked through how the prover & sequencer works, stepped through a sample transaction step by step, and got into just how his team was able to pull off opcode parity w Ethereum L1 (and some of the tradeoffs with supporting full EVM compatibility).
If you’re interested in deploying atop the zkEVM or just understanding how it works from a technical point of view, I think you’ll enjoy this episode!
