Ripple CTO David Schwartz believes Zero-Knowledge Proofs (ZK Proofs) could spark major innovation in blockchain, especially when integrated with XRP Ledger (XRPL). He envisions a “private ledger” that ensures both privacy and decentralization. While real-world applications are still emerging, Schwartz is confident meaningful use cases will arrive soon. ZK Proofs are expected to play a key role in XRPL’s future growth and the broader digital finance landscape.
