BIS Tests XRP Ledger to Anchor Official Statistics On-Chain in Proof-of-Concept Paper

A BIS working paper tested the XRP Ledger as a proof-of-concept for verifying official statistics on-chain. Here's what it found. A Bank for International Settlements (BIS) working paper tests the XRP Ledger (XRPL) as a proof-of-concept for verifying official statistics on-chain, recording cryptographic fingerprints of public datasets that publish in three to five seconds and verify in one to two. The Working Paper No 1374 essentially asks how statistical agencies can give users an independent way to check the origin and integrity of published data without changing their existing dissemination systems. International organizations (the BIS among them) rely on the SDMX standard to exchange official statistics, and the prototype binds each SDMX dataset to its source by hashing it and writing a single summary value to the ledger. Though only the fingerprints reach the chain, never the underlying numbers, so confidential data stays off-ledger, and the method extends to formats such as XBRL. The BIS has tested public blockchains before, including Project Mariana, which trialed wholesale central bank digital currency settlement on a public chain with the central banks of France, Singapore...
