The XRP Ledger (XRPL), a decentralized public blockchain designed for fast, low cost blockchain transactions, has integrated Boundless zero knowledge proofs (ZKPs) to provide banks and asset managers with confidential yet compliance friendly blockchain transactions.

 

The integration, announced Tuesday at XRPL Zone Paris during Paris Blockchain Week, will see XRPL leverage Boundless zero knowledge proofs to keep sensitive financial data private while maintaining the auditability and compliance of this data, exactly what banks and financial institutions have long requested on public blockchains.

 

 

According to Shiv Shankar, Chief Executive Officer of Boundless, the integration of Boundless zero knowledge infrastructure into the XRP Ledger will enhance institutional level privacy by shielding sensitive transaction details, including transaction size, frequency, and counterparties, from public view while still allowing regulators to audit transactions through selective disclosure and role based access controls.

 

Unlike most public blockchains, which allow anyone to see all activity on them, the Boundless XRPL integration cryptographically shields sensitive details about blockchain transactions. However, this does not mean that the XRP Ledger will be completely private or difficult for regulators to audit. Through role based access controls, XRP Ledger activity will still be visible and auditable to authorized parties.

 

This means that while the public will see almost nothing about a transaction, apart from confirmation that it occurred, a bank’s internal compliance team will be able to access more detailed information, and regulators will be able to request and receive comprehensive audit data when there is a valid basis to do so.

 

With this integration, banks, asset managers, and other large financial institutions will not have to make a trade off between transparency and confidentiality, as the Boundless integration upholds high standards of privacy while enabling regulatory oversight of blockchain transactions.

 

Blockchain Privacy Gains Momentum

Blockchain privacy continues to grow, evolving from a niche segment into broader institutional adoption among traditional financial institutions.

 

In March of this year, SWIFT, BNY Mellon, and some of the largest banks in the world, including HSBC, JPMorgan, and Citigroup, announced plans to build a blockchain based shared ledger on Linea, an Ethereum Layer 2 zk rollup developed by Consensys, the team behind MetaMask. Although this shared ledger is intended to facilitate fast cross border payments and the settlement of tokenized assets, it uses zero knowledge proofs to keep sensitive transaction details private.

 

In 2024, Deutsche Bank, alongside Privado ID, began testing the use of zero knowledge technology for decentralized, privacy preserving digital identity in banking systems and other financial infrastructure.
