ZK Trademark Controversy Unfolds

Leading zero-knowledge crypto projects, including Polygon and StarkWare, have called on zkSync to withdraw its "ZK" trademark applications ahead of its planned token launch. zkSync, developed by Matter Labs, reportedly plans to use "ZK" as its ticker, which has created tension with Polyhedra Network, which previously used the $ZK ticker and has switched to "ZKJ" for its exchange listings. Polygon cofounder Sandeep Nailwal and StarkWare CEO Eli Ben-Sasson signed a joint statement arguing that "ZK" should remain a public good, while Matter Labs CEO Alex Gluchowski defended the filings as defensive measures against dishonest actors.
