ChainCatcher message, Polyhedra Network responds to the previous Matter Labs regarding ZK as follows:"1. zkSync has shown the ZK trademark application to exchanges and attempted to seize the ZK code through the ZK trademark application. This is not for defensive purposes;There is no evidence that Vitalik has supported Matter Labs in the trademark application. In fact, ZK inventors Silvio Micali and Shafi have expressed opposition to the ZK trademark;In other fields, such as artificial intelligence, anyone can refer to it as AI. However, no individual or company can register the AI trademark because no one can truly represent or monopolize AI. If we allow one company to apply for the ZK trademark, it will set a bad precedent for the industry.Fortunately, Matter Labs' application has not yet been approved. We are speaking out to raise awareness in the industry that this behavior must be stopped. We hope Matter Labs will not monopolize under the guise of community and industry development and will withdraw the ZK trademark application."

ChainCatcher news, Linea officials posted on the X platform stating that Matter Labs is the entity behind zkSync and has just applied for the "ZK" trademark as its exclusive intellectual property. Zero-knowledge (widely referred to as ZK in our industry) is a field of cryptographic research co-created by researchers around the world. Many are scaling Ethereum through the zkEVM Layer 2 network. Claiming ownership of the cryptographic branch used to develop permissionless, decentralized L2 execution environments under a legal framework violates the development principles of Ethereum and the conventions of the field we are in. We are here to promote the development of Ethereum, to make the world a better place by providing a censorship-resistant network that increases freedom for people. We support @StarkwareLTD's statement that Matter Labs should adhere to their mission and withdraw their trademark application for ZK.
