May 30, 2024, 04:09 PM

Matter Labs, the company behind zkSync, is facing significant backlash from the cryptocurrency community after filing trademark applications in nine countries to claim the term 'zero-knowledge'. The move has been widely criticized as contrary to the open-source and collaborative ethos of the crypto industry, as outlined in the ZK Credo. Critics argue that trademarking such a fundamental cryptographic term could stifle innovation and limit the use of 'zero-knowledge' by other organizations. Matter Labs defended the decision, stating it was a protective measure to prevent misuse by bad actors. Many in the industry view Matter Labs' actions as an overreach and a departure from the principles of free competition and open-source development.
