Bank of England Test Opened a Route From DLT Systems to Central-Bank Settlement

The Bank of England reported on July 23, 2018, that the functionality planned for its renewed Real-Time Gross Settlement service could allow systems using distributed-ledger technology to connect and settle obligations in central-bank money.

The finding came from a proof of concept involving Baton Systems, Clearmatics Technologies, R3 and Token. It mattered because RTGS sits at the core of sterling wholesale payments: connecting an external ledger to that infrastructure could give an emerging payment system access to the same settlement asset used between regulated financial institutions.

The result was narrower than a production launch. The exercise used a cloud-based test service isolated from the Bank’s live systems, contained no live data and gave participants no access to the operating RTGS service. It did not test public cryptocurrencies, issue digital central-bank money or establish that any participant’s platform was commercially, legally or operationally viable.

What the test established

The test concentrated on prefunded deferred net settlement. Under that model, participating institutions place funds in a segregated RTGS account before obligations accumulated elsewhere are settled on a net basis. Prefunding caps potential obligations and is intended to remove settlement risk within the supported payment scheme.

Baton connected its DLT-based platform to the test application programming interface. According to the Bank’s report, Baton simulated funding and defunding accounts, margin payments, and bilateral and multilateral net settlement while reconciling its ledger with the test RTGS balances.

Clearmatics also connected to the interface. It tested movements into and out of collateral accounts, reflected those movements on its ledger, simulated trades between account holders and applied the resulting net settlement to RTGS accounts. Clearmatics built an additional interface to translate messages between the two systems.

R3 and Token did not physically connect platforms to the API. R3 instead mapped how Corda could interact with RTGS through an oracle, while Token evaluated the supplied design materials using its centralized-ledger framework. That distinction limits the broad statement that all four participants considered the planned functionality capable of supporting connection and settlement.

The unresolved bridge

The exercise also exposed a structural problem. Two participants required an intermediary interface to translate messages or provide evidence that funds had moved. The Bank said this could reintroduce points of trust and failure—the very dependencies that distributed systems were intended to reduce.

Participants proposed more flexible account structures and stronger cryptographic evidence from RTGS. In response, the Bank committed to consider single-account and other structures, investigate whether RTGS could provide and consume acceptable cryptographic proofs, and continue consulting financial-technology companies. Cryptographic-proof functionality was explicitly not promised for an early phase of the renewal program.

Legal and regulatory questions were outside the test, as was an assessment of the participants’ platform viability. The report therefore demonstrated technical compatibility under controlled assumptions, not authorization to operate a sterling payment system.

Market context, without a causal claim

Kraken’s daily exchange report for July 23, 2018, listed bitcoin at $7,753, up 2.95% over its daily measurement window, with $102 million of reported BTC turnover. Kraken reported $159 million across all markets and listed ether at $451.40, down 2.84%, on $27.6 million of turnover.

Those figures describe activity on one exchange rather than the global market. The surviving report does not specify its cutoff time, individual BTC trading pairs or conversion method for the dollar-denominated aggregate. Nothing in the Bank’s publication establishes that the proof-of-concept result caused bitcoin’s price movement. Its immediate significance was institutional: a major central bank had shown that an upgraded conventional settlement core could be designed to communicate with new ledger systems without placing DLT at the core of RTGS itself.
