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 itser

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, and Switzerland.

The system normalizes each file with Canonical XML 1.1, hashes it with SHA3-512 at the whole-file and per-series level, and collapses those hashes into one Merkle root written to the Memos field of an XRPL Payment transaction. Each file also carries a W3C Verifiable Credential in its header, signed by the publisher’s identity keys.

Cost and Simplicity

The memo approach needs no smart contracts, so the authors avoided gas costs and contract risk, and XRPL’s base fee of 10 drops, or 0.00001 XRP, put anchoring close to free. Batching compounds that.

A single ledger entry can cover thousands of datasets, dropping the on-chain cost to a fraction of a cent each. The paper also cites the ledger’s fast consensus finality and the published technical analysis of its consensus protocol.
