For the final installment of this three-part Ethereum Merge special edition of The Scoop, we take a closer look at zero-knowledge (ZK) rollups — technology that could enable Ethereum to scale to millions of transactions per second.
There are four main teams working on ZK-rollups: Polygon, Scroll, Starkware, and Matter Labs.
In this episode of The Scoop, Matter Labs Chief Product Officer Steve Newcomb shares what he believes to be the key ingredients of a good ZK-rollup, and why he believes scaling solutions will herald a new wave of innovation.
According to Newcomb, a paradigm shift will occur once Ethereum successfully scales:
“Once Ethereum can scale — and truly scale — it's kind of like coming out of Plato's cave and seeing the rest of the world, and seeing these use cases we could have never even predicted.”
Ethereum co-founder Vitalik Buterin has stated he believes ZK-rollups will be the main layer-2 scaling solution in the future, largely because of the speed at which users can move funds between mainnet and the layer-2.
Newcomb also believes that ZK-rollups are “going to be the end game for scaling,” although he also stipulates that a good ZK-rollup should meet the following requirements:
“These five ingredients — having a generalized ZK-rollup, being EVM compatible, working with solidity, being truly open sourced, being correctly decentralized, and having good tokenomics — these are the key ingredients of what makes a good ZK-rollup a ZK-rollup.”

Episode 93 of Season 4 of The Scoop was recorded remotely with The Block's Tim Copeland, VP of Research Larry Cermak and Matter Labs' Chief Product Officer Steve Newcomb.
