Ripple CTO David Schwartz has caused the discussion about zero knowledge (ZK) proving and predicting that cryptographic progress could bring a great shift into the blockchain space.
An X user claimed that private ledgers were technically impossible and are not part of the functionality of XRP Ledger (XRPL). Another X user reacted with a Tweet 2019 from Ripple CTO David Schwartz who describes a vision of interconnected private wholesalers: “For example, imagine 100 groups for those private whides want cheap transactions in the group. They can run any private ledbooks with real XRPs to/from the Public Xrms”
SCHWARTZ weighed the new life thread and shared new insights into how recent developments, in particular ZK certificates, can give life to this vision: “ZK Proofs make this more practical and safer and allows you to get close to the safety and decentralization guarantees of a low.” Schwartz added: “I am not convinced that cases are still here, but I suspect they will be one day.”
ZK Proofs make this more practical and safer and enables you to get free of a layer to the safety and decentralization guarantees. I am not convinced that cases are still here, but I suspect they will be one day.

Zero-knowledge-proofs (ZK restrictions) are cryptographic protocols with which one party can prove a statement, is where without additional information, making them an effective tool for privacy-retaining transactions on blockchain. Schwartz’s remark suggests that ZK Proofs could close the gap between private transaction systems and decentralized public chains.
ZK Proofs: what’s coming?
In a blog post in April entitled “Why I Support Privacy”, Ethereum co -founder Vitalik Buterin indicated that AI greatly increases the possibilities for centralized data collection and analysis, while the scope of data is voluntarily expanded.
Buterin proposed solutions that mainly presented for privacy problems on the basis of zero knowledge certificates (ZK-proofs), because this ‘fine-grained control over who can see which information’ makes possible.
“We have more powerful tools to maintain privacy, especially in the digital empire, than the Cyperks from the 1990s: very efficient zero knowledge certificates (ZK-SNAuks) can protect our identity while revealing sufficient information to prove that we are still reliable,” Benterfic coding (FHE) can be seen.
