Polygon’s technical lead explains what to expect from zkEVM

Polygon looks to be the first to deploy an Ethereum mainnet release for their zkEVM rollup set for Mar. 27.
The Ethereum ecosystem is set to witness one of the hottest blockchain trends this year, with numerous companies eager to exploit Polygon’s upcoming zkEVM rollup.
What are zero-knowledge proofs?
Zero-knowledge (ZK) technology is a cryptographic solution reshaping the blockchain industry. They execute languages and low-level bytecode at a programmable level, backed by the same rules as the Ethereum mainnet.
It is a virtual machine that utilizes zero-knowledge proofs to verify data without revealing any information about the data’s content or properties. It is a censorship-resistant protocol replicating the transaction execution environment of the Ethereum mainnet.
Vitalik Buterin, the founder of Ethereum, categorized zkEVMs into four main types.
Type-1 zkEVMs: fully equivalent to Ethereum
Type-2 zkEVMs: EVM (not Ethereum) equivalence
Type-3 zkEVMs: departing from EVM
Type-4 zkEVMs: close cousins to the EVM
“The project is a full engineering project,” said Jordi Baylina, who leads the technical team building the Polygon zkEVM. “The idea is that with these electronics, we somehow built a processor. On top of that, a program can be written that processes transactions. It’s a full stack of components with different teams working in each of these layers in these stacks.”
In a YouTube video released Mar. 2, Baylina explained the technical components behind the rollout, “the system that we are building is censorship resistant. It’s not a perfect solution, but up to a certain point because the system is not universal.”
