Other companies in addition to Matter Labs, like the research-oriented Scroll platform and the Ethereum juggernaut Polygon, are progressing on their own ZK-rollup platforms. Together, these firms represent the first cohort of a new class of so-called zkEVMS – ZK rollups which, unlike past applications of the technology (including an older version of the zkSync network), will be able to support virtually any program that runs on Ethereum.
