The adoption of ZKsync Validium permits UBS to boost the scalability, privateness, and interoperability of its digital gold providing.
By leveraging zero-knowledge proofs (ZK-proofs), this blockchain-based infrastructure ensures increased throughput transactions and improved information safety whereas conserving transaction prices low.
UBS Continues to Discover Blockchain Tech

In a Proof-of-concept, UBS deployed good contracts on a ZKsync Validium testnet to simulate the UBS Gold Community and replicate key features like
→ Gold token issuance
→ Transaction processing
→ Reconciliation
The profitable PoC demonstrated that ZKsync Validium mode was…— ZKsync (∎, ∆) (@zksync) January 31, 2025

These enhancements might make ZKsync’s Ethereum-native scaling options extra enticing to institutional gamers, enabling them to leverage blockchain with out the standard issues over excessive charges and community congestion.
Privateness stays a significant concern for establishments getting into the blockchain house.
Remi Gai, founding father of Inco, highlighted this problem throughout the FHE Summit 2024, stating that “establishments battle with blockchain’s transparency”.
