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.

XRPL has taken on other institutional workloads this year. CryptoPotato reported on a pilot that linked the ledger to interbank rails with JPMorgan, Mastercard and Ondo, which settled tokenized Treasury bills in under five seconds, and Ripple has published an institutional roadmap adding compliance credentials and permissioned trading. The BIS tests ran on XRPL’s DevNet, a test network.
It notes that DevNet shares the mainnet’s transaction format and close cadence, so the latency figures carry over, and mainnet fees stay in the sub-cent range.
A Few Firm Limits
The paper also describes the build as an experimental proof-of-concept, stating a production service would need hardware-backed signing, pinned validator nodes and formal load testing.
Though keep in mind the ledger certifies only what was published, by whom and when, so the paper reaches no adoption decision and gives no endorsement of $XRP, and the authors attribute the views to themselves, not to the BIS or its member central banks.
