UBS is pioneering blockchain technology by testing a digital gold investment product, UBS Key4 Gold, on the ZKsync Validium network, enhancing scalability and privacy for retail investors. This initiative follows the bank's recent launch of a tokenized fund on Ethereum, reflecting its commitment to integrating blockchain into traditional finance.ZKsync aims to process 10,000 transactions per second by 2025, significantly reducing fees. As privacy concerns hinder institutional crypto adoption, advancements in technologies like fully homomorphic encryption could unlock substantial capital for the crypto industry.
