With the upcoming launch of Polygon’s zkEVM mainnet, L2s are undoubtedly a huge narrative that is unfolding in 2023. It is time to take a step back and recognise the incredible amount of effort that has gone into researching and building L2 scaling solutions in general and zk rollups in particular. Tech-wise, we barely scratched the surface of general purpose processors that can handle zk circuits, so there is still tremendous room to grow. As layer 2s become more efficient, so will the applications that are dependent on blockchain throughput.
We were joined by Jordi Baylina (tech lead) & David Schwartz (CTO) from Polygon’s zkEVM, to discuss the different milestones & challenges they had to overcome in designing a zk rollup, from circuits to mainnet.
Topics discussed in the episode
- Jordi’s & David’s backgrounds
- The idea behind Hermez Network
- zkEVM scaling & validity proofs
- How different ZK rollup models function
- What challenges zkEVM encountered during development
- Evolutionary pathways in the realm of ZKPs
- Auditing zkEVM
- Trusted setup requirement for zkEVM
