If a client tells you your solution doesn’t solve their problem, it may not be the problem that needs to change…
I often argue for the importance of blockchain and distributed ledger technology by using the following chain of logic:
- Bitcoin’s architecture solved the problem of censorship-resistant digital cash
- But few, if any, financial firms are interested in censorship-resistant digital cash
- So why are they looking at this technology?
- Because some principles underpinning Bitcoin’s architecture – shared ledgers, for example – could be relevant to problems that banks face.
Sure, a blockchain or a replicated shared ledger could indeed be useful to banks. Perhaps it could reduce the need for reconciliation between firms if they all ran off a single ledger, for example. But this says nothing about whether blockchains are the optimal solution to any particular problem in banking. That still has to be argued, of course.
Recall: the bitcoin architecture was a solution to a very specific, very carefully framed problem – how to transmit value without the risk of censorship. Just because the underlying architecture could be used to solve some pressing problems in banking doesn’t mean it’s the best way to do so. Indeed, although the interlocking aspects of the Bitcoin solution are in some ways quite elegant, there are also some compromises. After all, it is an engineering solution to a set of very specific constraints and so it has to be demonstrated that it’s the right solution when the constraints are different.
Lee Braine, of Barclays Investment Bank CTO Office, made an important contribution to this debate when he spoke at London Blockchain Conference 2015 recently. The video is now available and I urge anybody working in this space to watch it and to internalise its message.[vimeo 137190236]
We all too often “talk past each other” in the distributed ledger world and we are quick to assume the other person just “doesn’t get it”. I can assure you that Lee does get it and it would be a brave startup in this space that chooses to disregard what he said. He’s giving us free advice! Take it!
Like I say, watch the video for yourselves.
I think another way to capture the chain of logic in the video is as follows:
- Assume the ongoing interest in the application of blockchain technology continues
- Assume further that some banks identify some compelling business opportunities in deploying a cryptographically-secure shared ledger between themselves.
- What is the probability that a derivative of Bitcoin or Ethereum or any other current platform will be the best solution to that specific problem?
- Given that none of them were invented to solve that problem, surely it’s quite low, right?
So we could find ourselves in the situation that bitcoin and blockchain technology have catalysed an orgy of activity, that this activity has identified countless high-quality business problems and yet none of those opportunities are best addressed with the technology that triggered the excitement in the first place!
The theme of this blog is “free advice” and the free advice I’m taking from Lee’s comments includes:
First, we shouldn’t get enamoured by a particular implementation of a technology. Sure: if you have an implementation then you may have bought a place at the table. But don’t make the mistake of assuming that if the business problem doesn’t fit the technology then it’s the business problem that needs to change!
Secondly, if you’re working in a financial institution, be careful to distinguish between the principles embodied in these technologies. Shared ledgers? Yes. That seems to be at the heart of this domain. Indiscriminate replication? Perhaps. Cryptographically-secured access down to the “row” level? Probably. And so on.
Thirdly, consider the complexity of banks’ existing IT environments. An idealised, “wouldn’t the world be perfect if…” solution is no use to anybody if it requires the whole world to move at once and/or if there is no credible migration path. This points to a need to listen to the incumbents when they object. Furthermore, consider the non-functional requirements which are simply a given in this space.
Fourthly, if we assume that today’s current hyperactivity will lead to a new understanding of the possibilities for banks but don’t assume that today’s blockchain platforms (permissioned or permissionless) are the (whole) answer, then surely we’re back in the land of engineering, architecture and hard work? Perhaps this means that the combination of persistence, data models, APIs, consensus, identity and other components that we need won’t all come from one firm. So a common language, some common vision and an ability to collaborate may become critical. Where is your distinct differentiation? Where would you fit in an overall stack?
Another insightful post. Some thoughts though. Is it possible that tailoring the problem to meet the functionality of an already existing and proven technology (Bitcoin) is better than keeping the problem untouched and using an unproven and non-existent technology? Does the security of the Bitcoin blockchain (network effect) make it the better or more feasible than some new technology (less secure and unproven) designed to solve your exact problem?
P.S. I am only an enthusiasts who is intrigued by the entire space. It’s likely I’m far off.
Food for thought indeed.. In the world of collaboration and interlocking, standardization is key. Another free advice: don’t only think how to cooperate, but how to standardize (language, reference data, values, knowledge, wisdom, culture).
Great Post! Regards Lucas
@brett – good points… thanks for sharing.

Hi Richard, Ian Allison from IBT has suggested I contact you with regards to a Cryptocurrencies panel that I am organising on the 6th October at an FS industry event. Details can be found here – https://www.amiando.com/LinedataExchange_London.html?page=1268747
Please can you contact me – many thanks Helen
Thanks Richard – another great post, perfectly placed at the intersection between the finance and tech worlds.
I think that some bitcoiners (including myself) have been guilty of believing that bitcoin provided such an improvement on the current financial system that people will blindly leave the “walled gardens” of fiat assets in the same way that they moved from CD’s to mp3 based tech. While this may be true for the millions of under-banked, whose only interaction with these systems is a monthly Western-Union wire from a relative abroad, this is a long way from being on the banking threat radar.
What bitcoin tech offers in terms of cost reduction is enticing to the banking industry, but the requirements that these institutions are obligated to place are not aligned with what bitcoin has to offer, meaning that alternative uses of the technology must be explored.
Although saying that, I wouldn’t be surprised if start ups such as Factom will be an important part in allowing banks to hedge their experiments. If you can regularly post a hash of your permissioned Blockchain on the unpermissioned Blockchain ledger for what is a trivial financial cost, then I can’t see any reason why you can’t ride both horses.
Another insightful post Richard! We in the FCA’s Innovation Hub are keen readers of your blog. In fact we were wondering whether you’d be happy to talk to us about blockchain tech at some point. We’ve identified a number of legal/regulatory barriers to more widespread use of this protocol and we’d like to understand how/whether these barriers ought to be tackled. All the best!

Probably the best blog post about an insight I’ve seen all day today
Great post. Bringing my knowledge a bit further. Thanks!
These days so many Free advice available. yo just need to find it and see the credibility before you use it.
Great article, we will Tweet this..
Agree with earlier Comment. If you go to youtube there are soo many Videos on how to make money, how to create a Business and etc. However, the main problem is the credibility of these Free advice.
