UBS tests blockchain for tokenized gold on ZKSync, enhancing scalability, privacy, and efficiency. Experts see this as a major financial innovation.

Swiss banking giant UBS has taken a new step in blockchain technology. The bank recently tested its UBS Key4 Gold product on Ethereum's Layer-2 network

Swiss banking giant UBS recently tested its UBS Key4 Gold product on Ethereum’s Layer-2 network ZKSyn. The research aimed to evaluate blockchain technology as a means of enhancing the gold investment framework while preserving user privacy and operational efficiency.

The Proof-of-Concept (PoC) test was conducted within a ZKsync test network. Space Research and Development (SR & D) forms a key component of UBS operations, along with its previous blockchain trials such as uMint and the tokenized money market investment. The bank is currently exploring blockchain technology solutions for developing fractional gold investment services catered towards retail clients.

Key4 Gold by UBS offers several benefits to its users. The service provides access to the current gold market value and unlimited transaction volume, while also ensuring secure storage facilities. Through its system, clients have the ability to request physical delivery of their gold. The UBS Gold Network operates the permissioned blockchain system that connects vaults together, along with liquidity providers and distributors.

Three major setup challenges had to be overcome by UBS for the implementation of this blockchain trial. Initial scalability was crucial, as the system needed to be able to handle high transaction volumes. Privacy measures had to be implemented to protect customer data.

The Validium mode from ZKsync helped UBS solve its operational challenges. This technology enables data placement off-chain, resulting in fast and efficient transaction processing capabilities. During their testing operation, smart contracts were activated by UBS to represent real gold trades. The deployed contracts served to create gold tokens and perform transactions and record any discrepancies.

This development is being hailed as a major advancement by blockchain experts. Alex, who co-invented ZKsync, predicted that zero-knowledge technology combined with blockchain will become the next big thing in financial systems.

The Digital Assets Lead at UBS Christoph Puhr shared his thoughts on the platform. He outlined that digital finance faces challenges in scaling operations, maintaining user privacy, and enabling cross-system communication. The demonstration using ZKsync applications proved that networks at the second layer can help solve these current challenges.

The demonstration by UBS brings tokenized gold investments closer to commercial viability. Interest in Web3 solutions continues to grow, leading blockchain to reshape banking operations. The test serves as an indication of financial institutions embracing decentralized technology to shape the future of finance.
