The Bank for International Settlements (BIS) has conducted a trial using the XRP Ledger as a public verification layer to enhance the integrity of official economic statistics. The experiment centers on leveraging blockchain technology to ensure that digital datasets remain unaltered from the point of publication to their consumption by end users.
Blockchain for validating statistical data
Increasingly, key economic statistics are distributed digitally and consumed by automated platforms, including artificial intelligence tools. While SDMx, the Statistical Data and Metadata eXchange standard, already helps institutions distribute data, concerns persist about the ability of recipients to verify the authenticity and integrity of official publications.
In response, the BIS developed a prototype verification system that captures a dataset’s cryptographic fingerprint and records it independently using blockchain. This approach allows any user who downloads an official dataset to confirm its authenticity and verify that it has not been tampered with after publication.
The system utilizes the XRP Ledger (XRPL), a decentralized, public blockchain designed for fast, low-cost transactions. The BIS chose XRPL because of its minimal transaction fees and rapid confirmation times, which are critical for real-time or near-real-time records.

Technical details and performance
The BIS prototype operates by storing the cryptographic root of a dataset on the XRP Ledger via a Payment transaction, utilizing the memo field. This method ensures a permanent and transparent record, enabling post-distribution verification of the dataset’s integrity.
During testing on XRPL’s DevNet environment, the system recorded a median publication latency of three to five seconds, while the process to verify a dataset’s fingerprint took roughly one to two seconds. The BIS paper notes that, although the prototype is currently based on SDMx, the architecture could be expanded to accommodate other structured reporting formats, such as XBRL.
| Key Feature | BIS Prototype Result |
|---|---|
| Median Publication Latency | 3 to 5 seconds |
| Verification Time | 1 to 2 seconds |
| Blockchain Used | XRP Ledger (DevNet) |
| Dataset Format | SDMx (with potential for XBRL) |
Limitations and future implications
The experiment remains a proof of concept and is not being positioned as an operational solution. However, it highlights a novel application for the XRP Ledger, which is often subject to skepticism regarding its real-world use cases beyond cross-border payments.
A BIS paper emphasizes that their system, designed on the XRP Ledger, delivers rapid data publication and near-instant verification, while remaining flexible enough to extend to other reporting frameworks in the future.
By demonstrating blockchain’s potential in verifying official data, BIS has opened up new possibilities for how institutions could maintain public trust in their economic reporting streams.
