Bank of England payments infrastructure would be Blockchain friendly, not Blockchain based

A few weeks ago, two inspiring leaders provided contradicting views on Blockchain and Bitcoin. Jack Ma, along with the announcement of his Blockchain based remittance product made a comment that Blockchain had legs, but Bitcoin was doomed.

A few days later Steve Wozniak shared his views that Blockchain was over-hyped (rather dead) and Bitcoin was the thing to follow closely. I was surprised at such contradiction. I have generally agreed with Jack’s view of the world in this context. But when it comes to developments within banking, I am starting to think Steve was more right.

Over the last couple of years, we have seen consortiums, pilots and prototypes using Blockchain fail badly. I wrote about Swift’s Blockchain PoC and the learnings from that a few weeks ago. The conclusion was that,

  • Banks’ back office capabilities needed to get better to use DLT
  • Blockchain scalability must be proven in a commercial environment

After a disappointing PoC with Ripple, Bank of England were conducting another PoC of their new RTGS infrastructure and its interoperability with DLT. And when I went through the results they published, a couple of thoughts crossed my mind.

  • They were largely hedging themselves against a sudden surge in mainstream use of Blockchain – however I largely doubt this would be the case where it involved interfacing with legacy systems and processes.
  • I couldn’t help feeling that BoE were also trying to find a problem that Blockchain would solve – desperately.

These are the key takeaways from the PoC

  • The purpose was to test how the revamped RTGS infrastructure could support settlement for systems operating on innovative payment technologies such as DLT.
    • NOTE: The purpose wasn’t to use Blockchain to execute the payments
  • A cloud based test RTGS service was used, and the participants (with their DLTs) connected to this service using APIs.
  • The results in a gist was that, RTGS could interface with DLT. (EUREKA!!)

Four participants were involved in the PoC

  • Baton: Who connected to the test RTGS service through APIs and used their DLT to provide settlement services. They also demonstrated that a node could manage market risk in real time
  • Clearmatics: Who tested out interoperability of their DLT platform with the RTGS service. They also provided inputs on how cryptographic signatures and proof schemes could help BoE build decentralised systems.
  • R3: While they weren’t connected to RTGS, they came up with the recommendation that the BoE should run a node on the network to achieve greater efficiencies
  • Token: Another participant who didn’t physically connect to the RTGS API, but provided their views on how settlement and collateralisation accounts interact.

But that’s hardly progress. Connecting to a data stream (RTGS) using APIs, pulling some data and using Blockchain to act as a real time ledger in a test environment – doesn’t sound like rocket science to me.

If anything, it feels like a half-hearted attempt to make headlines with “BoE”, “Blockchain” and “successful prototype” on it.

It might be that, Blockchain within banking needs a break, a step back, a deep breath and a re-engage. Its been a good English summer (so far), and time for some tough test cricket. Blockchain hasn’t scored enough in the first innings, got to see if it can do better following on.
