BIS Trials Blockchain Anchoring to Authenticate Official Statistics
On September 2, 2026, the Bank for International Settlements (BIS) published Working Paper 1374, detailing an experiment that anchored cryptographic hashes of official statistical data onto the XRP Ledger (XRPL). This initiative aimed at verifying the data's origin and integrity without storing underlying datasets on-chain, focusing instead on providing tamper-evidence for official statistics.
Efficient Data Integrity Through Hash Anchoring
The process utilized the SHA3-512 algorithm to generate encrypted digests for each dataset. These individual hashes were then aggregated via a Merkle tree structure into a single root hash, which was subsequently recorded on the XRPL. To establish data provenance, the statistical agencies’ identities were confirmed through digital signatures structured as W3C verifiable credentials. This method enables users to perform a single ledger query to confirm both the authenticity of the data and the identity of its issuer.
XRP’s Role Limited to Transaction Fees
Within this proof-of-concept, XRP was employed solely to cover the ledger's low fixed transaction fees. It was neither tracked as an asset nor integrated into the data verification process, highlighting XRP’s utility in facilitating cost-effective operations on the blockchain.
Rapid Anchoring and Validation Times Support Real-Time Needs
Testing revealed median anchoring times between 3 and 5 seconds from data submission to recording on the ledger, with validation queries completing in just 1 to 2 seconds. These performance metrics demonstrate XRPL’s capacity to support official data disclosures that demand real or near-real-time trust assurances.
Addressing Gaps in International Data Exchange Standards
The experiment specifically complemented the existing Statistical Data and Metadata eXchange (SDMX) protocol, which lacks cryptographic authentication and tamper-proofing features. By leveraging blockchain-based cryptographic anchoring, the BIS addressed a trust deficit in the international statistical data exchange framework, enhancing data security across institutional boundaries.
Implications for Regulatory Transparency and Data Reliability
This BIS initiative showcases the practical application of blockchain technologies like XRPL in strengthening data transparency and regulatory trustworthiness. As governments and agencies worldwide intensify focus on data integrity and compliance, blockchain-enabled verification methods could see increasing adoption. Future developments will need to balance privacy safeguards and data security with scalable, cost-efficient cross-institution validation mechanisms.
