Polyhedra and zkSync Clash Over 'ZK' Token Ticker Amid Trademark Applications

May 30, 2024, 02:09 PM

Polyhedra and zkSync are in a dispute over the token ticker 'ZK', with the community largely supporting zkSync. Matter Labs, associated with zkSync, has filed trademark applications in nine countries to claim the term 'zero-knowledge' as exclusive intellectual property, sparking outrage within the crypto industry. Critics argue that attempting to trademark a cryptographic primitive is a miscalculation and in poor taste. zkSync defends its actions, stating the need to prevent trademark squatters from exploiting the term. The trademark attempt has been described as a 'Cypher-Larp' move, and zkSync's actions are aligned with the ZK Credo, which rejects the concept of intellectual property but supports protective trademarks.
