The Bank for International Settlements has published a working paper presenting a proof of concept that anchors official statistics to their source using the XRP Ledger. The paper, “Verifiable official statistics: a blockchain-based approach,” was released on 2 September 2026 and describes a method for binding statistical datasets to cryptographic fingerprints recorded on-chain, so a user can confirm both who issued a dataset and that its figures are unchanged.
How the Proof of Concept Works
The approach builds on SDMX, the standard the BIS and other international organisations use to exchange statistical data and metadata. For each published dataset — and, where needed, each individual time series — the authors compute a cryptographic fingerprint. A single summary value covering a batch of datasets is then recorded on the XRP Ledger, where it is timestamped and cannot subsequently be altered. The published file carries everything needed to check it, including a digitally signed credential identifying the publisher, so verification requires the file alone plus one lookup on the ledger. The authors also provide an open-source reference implementation.
Speed and Cost of the System
In the prototype, publishing takes three to five seconds and verification one to two seconds, fast enough for interactive use and for automated systems that consume data in real time. The authors caution that these figures describe a proof of concept rather than a hardened production system. The cost analysis finds on-chain fees are negligible once modest batches are used, since a single ledger entry can cover thousands of datasets, leaving ordinary processing and storage as the dominant costs. The authors derive an optimal batch size to balance cost efficiency against the delay that batching imposes on urgent releases.
Why Verifiable Statistics Matter
BIS researchers frame the work as a response to a longstanding problem: trust in published data is essential for evidence-based policymaking, yet datasets are normally distributed without an easy way to prove they have not been tampered with. Because only fingerprints — never the underlying data — are placed on-chain, the method adds verifiability without exposing confidential figures. The proof of concept places the XRP Ledger among the public blockchains being tested for institutional use, alongside growing institutional XRP participation in regulated futures markets and Ripple’s institutional custody and tokenization efforts .
