Matter Labs, the development team behind Ethereum's layer-2 scaling solution zkSync, has retracted its attempts to trademark the term "ZK," representing "zero knowledge" proofs, in response to widespread criticism from the community.

The decision to withdraw the trademark applications came shortly after several prominent ZK researchers condemned Matter Labs' actions, emphasizing the importance of ZK innovations as a public good that should be accessible to all.

In a statement posted on X on June 2, Matter Labs acknowledged the concerns raised by the community and announced their decision to abandon all trademark applications related to the term "ZK." They highlighted the impossibility of reaching a consensus on trademark ownership, recognizing the need for impartiality in such matters.

The public outcry against Matter Labs' trademark attempts was evident in a letter signed by seven influential figures, including Shafi Goldwasser, Silvio Micali, Eli Ben-Sasson, and Sandeep Nailwal, among others. The letter emphasized the fundamental principle that ZKs should remain a public resource rather than being subject to corporate ownership.

Initially, Matter Labs had pursued the trademark applications under the pretext of protecting specific product names like "ZK Sync" and "ZK Stack." However, the community expressed concerns that such actions could lead to the privatization of a term that should remain freely accessible to all participants in the cryptocurrency sector.

The controversy surrounding the trademark issue coincided with preparations for an airdrop scheduled for mid-June, adding further urgency to the resolution of the matter.

ZkSync, powered by ZK-proof technology, stands as a prominent Ethereum Layer 2 solution, offering an alternative approach to scalability compared to networks like Optimism and Arbitrum. Its integration with the USDC stablecoin ecosystem by Circle signifies a significant milestone in enhancing liquidity and usability within zkSync, promoting greater efficiency and cost reduction.

As Matter Labs retreats from its trademark pursuits, the incident underscores the importance of community consensus and the preservation of open access principles within the decentralized finance landscape.
