According to BlockBeats, on June 3, Matter Labs, the entity behind zkSync, decided to abandon all trademark applications for the term "ZK". Previously, Matter Labs filed trademark applications for "ZK" in 9 countries, claiming that the term "zero knowledge" was the company's exclusive intellectual property, which caused widespread dissatisfaction in the crypto industry. Polyhedra, Polygon and StarkWare issued a joint statement stating that ZK should not be a company's trademark and "should continue to be a public product."
