The Bank for International Settlements published Working Paper No. 1374 on September 2, describing a proof-of-concept system that uses the XRP Ledger (XRPL) to verify the authenticity and integrity of official statistics. The prototype addresses a limitation in SDMX, the standard for exchanging statistical data and metadata, by anchoring cryptographic fingerprints of datasets on XRPL and issuing a W3C Verifiable Credential for each publisher. It generates SHA3-512 hashes, organizes them into Merkle trees and records the resulting fingerprint on the ledger, allowing users to check a dataset with one ledger lookup and a file. Under controlled conditions, publication latency had a median of 3 to 5 seconds, verification took 1 to 2 seconds, and batching reduced the estimated transaction cost to about $0.000003. The authors, including Mario Rusev and four staff members from the BIS Monetary and Economic Department, cited low fees and rapid consensus finality in selecting XRPL. Ripple CEO Brad Garlinghouse said the experiment was unsurprising, pointing to XRPL's low fees, fast settlement and track record. The BIS said the research is experimental, is not an endorsement of XRPL or a commitment to production implementation, and described the prototype as unmaintained. XRP had separately gained 6% in 24 hours as its price approached $1.5.
