In recent blockchain news, Polygon, StarkWare, and Polyhedra have expressed strong opposition to zkSync's use of the ZK ticker. The three entities have demanded that Matter Labs, the company behind zkSync, withdraw its trademark application for the term "zero knowledge."

The dispute centers on the use of the term "zero knowledge," a fundamental concept in cryptography, which zkSync is attempting to trademark. The opposing parties argue that such a move would limit the use of a term that is widely used and understood in the blockchain community.

The situation highlights the ongoing debates within the blockchain industry over the use and ownership of key terms and concepts. As the industry continues to grow and evolve, such disputes are likely to become increasingly common.
