Matter Labs, the company behind the ZkSync Ethereum Layer 2 network, has decided to drop its efforts to trademark the term "ZK" following significant backlash from prominent figures in the zero-knowledge proof community. This decision comes after the company faced intense opposition from leading projects and researchers in the field.

Matter Labs attributed their decision to the difficulty in finding a neutral group of people to oversee the trademark application process, stating that "it would be impossible to agree on a group of people perceived as credibly neutral by nearly everyone." This announcement was met with relief from the ZK community, as many felt that trademarking the term would have been detrimental to the open nature of the technology.

The controversy surrounding ZkSync's trademark application began when several representatives of leading ZK projects, including co-inventors of ZK proofs and CEOs of prominent companies, released a joint statement condemning the move. They argued that "ZK should remain a public good" and that trademarking it would go against the principles of the crypto and Ethereum communities.

The timing of this controversy was particularly notable, as ZkSync is planning for an airdrop in mid-June. Furthermore, its intention to use the ticker ZK led to a clash with Polyhedra, which opted to use the ZKJ ticker for its own token listing. ZkSync is one of the most popular Ethereum Layer 2 blockchains built on ZK-proof technology, which offers enhanced security and scalability for decentralized applications.

In contrast to other networks like Optimism, Arbitrum, and Blast, which favor the optimistic rollup strategy, ZkSync has gained popularity for its ZK-proof technology. According to The Block's data, ZkSync often has the highest seven-day moving average of transactions out of all ZK-powered Layer 2 Ethereum networks. However, its competitor Linea recently faced an exploit on its network, leading to a pause in operations.

The decision by Matter Labs to drop its trademark application is seen as a positive move for the ZK community, ensuring that this technology remains accessible to all. It highlights the importance of collaboration and open innovation in the crypto space, and serves as a reminder that public goods should remain just that – public.
