The Bank for International Settlements proposed a solution based on XRPL verification statistics

The Bank for International Settlements (BIS) released Working Paper 1374, proposing a technical solution based on the XRP Ledger (XRPL) to verify the source and integrity of official statistical data. This solution generates cryptographic fingerprints for SDMX datasets and records the hash values of batch data on the XRPL, while the original data itself is not stored on the chain.

Users can verify the identity of data publishers and whether the data has been tampered with through digital signature credentials combined with a one-time on-chain query. Prototype testing results show that data publication takes about 3 to 5 seconds, while the verification process only takes about 1 to 2 seconds. The paper specifically notes that this system is currently only in the proof-of-concept stage and has not yet been put into a formal production environment.
