BIS Researchers Test XRP Ledger Prototype for Verifying Official Statistics

Researchers affiliated with the Bank for International Settlements (BIS) evaluated a prototype built on the XRP Ledger (XRPL) Devnet as a verification layer for official statistical data. The system records cryptographic fingerprints of datasets rather than publishing the full data on‑chain, allowing recipients to confirm data integrity and publisher identity.

How the Prototype Works

Before publishing, an SDMX file is converted to a standard format and a SHA3‑512 hash is calculated. For files containing multiple statistical series, individual hashes are combined into a Merkle root, which is anchored in a single XRPL transaction. The transaction reference is embedded in the SDMX file, enabling verifiers to locate the on‑chain record and compare hashes.

Performance Results

• Median publication latency: 3–5 seconds (time to create and confirm the blockchain record).
• Verification time: 1–2 seconds (re‑calculating the hash and checking against the XRPL record).

These measurements were obtained under controlled conditions on XRPL Devnet, which uses test XRP and differs from the public mainnet in activity and reliability.

Identity Verification

The prototype incorporates a publisher identity system using a W3C Verifiable Credential signed by a key linked to the publisher’s XRPL address. This allows recipients to confirm that the file originates from an authorized source.

Scope and Limitations

The system does not assess the accuracy of the statistical content—only that the file matches the version anchored on the ledger. The code is released as an unmaintained proof of concept and is not intended for production deployment. Additional work on security, governance, revision handling, and privacy compliance would be required before official statistics agencies could adopt the approach.

Potential Extensions

The authors suggest future enhancements such as zero‑knowledge proofs for selective data verification and machine‑readable records to support AI agents that automatically consume statistical feeds.

Implications for XRP Ledger Use Cases

While the prototype uses XRPL infrastructure, it does not involve XRP for payments or settlement; only a minimal transaction fee would be needed to anchor each record on the mainnet. The experiment broadens the range of non‑financial applications being explored on the XRP Ledger.
