BIS Publishes Working Paper: Exploring Blockchain-Based Verification Solutions for Official Statistical Data

According to BIS Working Paper 1374 released by the Bank for International Settlements (BIS), the BIS, together with several researchers, has proposed a verifiable framework that binds official statistical data to the blockchain. The solution computes cryptographic fingerprints for SDMX datasets and anchors the digest values to the XRP Ledger, enabling independent verification of data provenance and integrity while leaving existing data publication workflows unaffected. Prototype tests show a data publication latency of approximately 3–5 seconds and a verification latency of approximately 1–2 seconds, meeting the requirements for real-time interactions and automated systems. Since only fingerprints, rather than raw data, are stored on-chain, data confidentiality is preserved. Cost modeling indicates that on-chain fees become negligible after batch processing, with a single ledger record capable of covering thousands of datasets. The study also provides an open-source reference implementation and reserves capacity for future integration of zero-knowledge proofs and AI-driven automated verification.
