BIS Taps XRP Ledger for Data Integrity Proof-of-Concept
The Bank for International Settlements (BIS) has developed a proof-of-concept system that uses the XRP Ledger to verify the authenticity of official statistics. The working paper, released on September 2, describes how the system anchors cryptographic fingerprints of economic datasets on XRPL, allowing anyone to independently confirm that published data hasn't been tampered with.
The current standard for exchanging official statistics between institutions is called SDMX (Statistical Data and Metadata eXchange). However, it has a blind spot: there's no built-in cryptographic mechanism to verify the data received is the same as the original publication or the publisher's identity. The BIS prototype fills this gap by generating SHA3-512 hashes of the data, organizing them into a Merkle tree structure, and anchoring the resulting fingerprint on the XRP Ledger.
The system also creates W3C Verifiable Credentials for each dataset to handle publisher authentication. This results in a verification process that requires just one ledger lookup and a simple file. Under controlled conditions, the prototype recorded a median publication latency of 3-5 seconds and a verification latency of 1-2 seconds, with per-transaction costs of around $0.000003.
The BIS researchers chose the XRP Ledger due to its low transaction fees and rapid consensus finality. They noted that the underlying approach isn't locked to XRPL and could be adapted to other ledgers or extended to verify different data formats like XBRL. The system doesn't put actual statistical data on-chain, only anchoring hashes that reveal nothing about the underlying information.
The BIS emphasized that this research is experimental and does not represent a commitment to production implementation. It's described as an unmaintained prototype within a broader experimental framework.
