Building innovation with blockchain

Sponsored Building innovation with blockchain Deploying blockchain technology can bolster innovation and create a more secure way to bank, according to Suresh Shetty, the CTO at Onyx by J.P.Morgan at JPMorgan Chase. In association withJPMorgan Chase & Co. In 2015, JPMorgan Chase embarked on a journey to build a more secure and open wholesale banking. For chief technology officer at Onyx by J.P.Morgan, Suresh Shetty, investing in blockchain, a distributed ledger technology in its early days, was about ubiquity. “We actually weighted ubiquity in terms of who can use the technology, who was trying to use the technology over technology superiority,” says Shetty. “Because eventually, our feeling was that the network effect, the community effect of ubiquity, actually overcomes any technology challenges that a person or a firm might have.” Years later, JPMorgan Chase has Onyx, a blockchain-based platform to leverage innovations at scale and solve real-world banking challenges. Chief among them are global wholesale payment transactions. Much more complicated than moving money from point A to point B, Shetty says, wholesale transactions require multiple hops and fulfilling regulatory obligations. Transferring money around the world requires several steps, including a credit check, sanctions check, and account validation. The process can lead to errors and hiccups. This is where blockchain comes in. “Now, as you can imagine, because of the friction in this process and the multiple hops, it is a process that’s very prone to error. So this is one of the ideal use cases for a blockchain, where we try to take out that operational friction from any process.” Although blockchain has the potential to cause major waves in financial services from securing transactions to ensuring smooth operations, sustainability remains a major consideration with any technology deployed at this scale. The shift from proof-of-work to proof-of-stake systems, says Shetty, reduces emissions and computing energy. “The amount of energy that’s being used in a proof of stakes system goes down to 1% of the overall carbon impact of a proof of work system, so thereby, that shift alone was very important from a carbon emission perspective.” This episode of Business Lab is produced in association with JPMorgan Chase.

Our topic today is blockchain. Technology has changed how money moves around the world, but the opportunity and value from distributed ledger technology is still in its early days. However, deploying on a large scale openly and securely should move it along quickly. Two words for you: building innovation. My guest is Suresh Shetty, who is the chief technology officer at Onyx by J.P.Morgan at JPMorgan Chase. This podcast is produced in association with JPMorgan Chase. Welcome, Suresh. Suresh Shetty : Thank you so much, Laurel. Looking forward to the conversation. Laurel : So to set the context of this conversation, JPMorgan Chase began investing in blockchain in 2015, which as we all know, in technology years is forever ago. Could you describe the current capabilities of blockchain and how it’s evolved over time at JPMorgan Chase? Suresh : Absolutely. So when we began this journey, as you mentioned, in 2015, 2016, as any strategy and exploration of new technologies, we had to choose a path. And one of the interesting things is that when you’re looking at strategic views of five, 10 years into the future, inevitably, there needs to be some course correction. So what we did in JPMorgan Chase was we looked at a number of different lines of inquiry, and in each of these lines of inquiries, our focus was trying to be as inclusive as possible. So what we mean by that is that we actually weighted ubiquity in terms of who can use the technology, who was trying to use the technology over technology superiority. Because eventually, our feeling was that the network effect, the community effect of ubiquity, actually overcomes any technology challenges that a person or a firm might have. Now, I think that a very relevant example is the Betamax-VHS example. It’s a bit dated but I think it really is important in this type of use case. So as many of you know, Betamax was a superior technology at the time and VHS was much more ubiquitous in the marketplace. And over time, what happened was that people gravitated, firms gravitated towards that ubiquity over the superiority of the technology that was in Betamax. And similarly, that was our feeling too in terms of blockchain in general and specifically the path that we took, which was in and around the Ethereum ecosystem. We felt that the Ethereum ecosystem had the largest developer community, and we thought over time, that was where we needed to focus in on. So I think that that was our journey to date in terms of looking, and we continue to make those decisions in terms of collaboration, inclusiveness, as opposed to just purely looking at technology itself. Laurel :And let’s really focus on those efforts. In 2020, the firm debuted Onyx by J.P.Morgan, which is a blockchain-based platform for wholesale payment transactions. Could you explain what wholesale payment transactions are and why they’re the basis of Onyx’s mission? Suresh : Absolutely. Now, it was interesting. My background is that I came from the markets world and markets is really involved in front office trading, investment banking and so forth, and eventually, went over to the payments world. And if you juxtapose the two, it’s actually very interesting because initially, people feel that the market space is much more complicated, much more exciting than payments, and they feel that payments is a relatively straightforward exercise. You’re moving money from point A to point B. What actually happens is actually, payments is much more complicated, especially from a transactional perspective. So what I mean by that is that if you look at markets, what happens is if you do a transaction, it flows through. If there’s an error, what you do is that you correct the initial transaction, cancel it, and put in a new transaction. So all you do is that there’s a series of cancel corrects, all of which are linked together by the previous transaction, so there’s a daisy chain of transactions which are relatively straightforward and easy to migrate upon. But if you look at the payments world, what happens is that you have a transaction, it flows through. If there’s an error, you hold the transaction, you correct it, and then keep going. Now, if you think about it from a technology perspective, this is a lot more complicated because what you have to do is you have to keep in mind the state engine of the transactional flow, and you have to store it somewhere, and then you have to constantly make sure that as it flows to the next unit of work, it actually is not only referenced but it actually has the data and transactionality from the previous unit of work. So a lot more complicated. Now, from a business perspective, what cross-border payments or wholesale payments involved is that, as I mentioned, you’re moving money from point A to point B. In an ideal fashion, and I’ll give you an example. Since I’m in India, in an ideal example, we would move money from JPMorgan Chase to State Bank of India, and the transaction is complete, and everybody is happy. And in between that transaction, we do things like a credit check to make sure that the money that is being sent, there’s money in the account of the sender. We need to make sure that the receiver of the account has a valid bank account, so you need to do that validation, so there’s a credit check. Then on top of that, you do a sanctions check. A sanctions check means that we are evaluating whether the money is being moved to a bad actor, and if it is, we stop the transaction and we inform the relevant parties. So it looks relatively straightforward in an idealized version. Unfortunately, what happens is because of the fractured nature of banking across the world as well as regulatory obligations, what happens is that it’s never a single point to point movement. It involves multiple hops. So in that same example where I’m moving money from JPMorgan Chase to India, what usually happens is JPMorgan Chase sends it to, let’s say Standard Chartered in England. Standard Chartered then sends it to State Bank of India. State Bank of India then sends it to Bank of Baroda, and then Bank of Baroda eventually sends it to my bank, which is Vijaya Bank in India. In each of those steps or hops, a credit check happens, a sanctions check happens, and the money moves forward. Also, there’s an account validation step that also happens to make sure that the payment transactional flow is correct, as well as the detail in the payment messages are correct as well. Now, as you can imagine, because of the friction in this process and the multiple hops, it is a process that’s very prone to error. So this is one of the ideal use cases for a blockchain, where we try to take out that operational friction from any process. Laurel: That’s a really good illustrative example since one of the benefits of being a global firm is that JPMorgan Chase can operate at this massive scale. So what are some of the benefits and challenges that blockchain technology presents to the firm? I think you kind of alluded to some there. Suresh : Absolutely, and it’s interesting, people sometimes conflate the technology innovation in the blockchain with a moonshot. Now, what’s interesting is that blockchain itself is based on very sound computing principles that have been around for a very long time, which are actually based on distributed computing. So at the heart of blockchain, it is a distributed computing system or platform. Now, all the challenges that you would have in a distributed computing platform, you would have within blockchain. Now this is further heightened by the fact that you have multiple nodes on the network. Each of those nodes has a copy of the data as well as the business logic. So one of the real challenges that we have is around latency in the network. So the number of nodes is directly correlated to the amount of latency that you have in the network, and that’s something that in a financial transaction, we have to be very cognizant about. Secondarily is that there is an enormous amount of existing assets that are already in place from a code perspective within the enterprise. So the question is do we need to rewrite the entire code base in the languages that are supported by the various blockchains? So in Ethereum, do we need to rewrite all of this in Solidity, or can we somehow leverage the language or the code base that’s already been created? Now in our experience, we’ve had to actually do quite an extensive analysis on what needs to be on chain as opposed to what needs to be off chain. The off chain code base is something that we need to be able to leverage as we go forward because the business feels comfortable about that, and the question is why would we need to rewrite that? And the stuff that’s on the chain itself, that needs to be something that we really feel is important to be able to be distributed to the various nodes in the network itself. So I think that that’s some of the challenges that we’ve had in the blockchain space. Now, in terms of benefits, I think that at the end of the day, we want to be able to have a cryptographically secure, auditable transactional record. And I think that there are many use cases within banking, especially those that are really within the sweet spot of the blockchain, such as those that require a lot of reconciliation. There are multiple actors, and in a distributed platform, regardless of whether it’s in blockchain or not. Laurel: And cybersecurity is definitely one of those areas where blockchain can help, for example, transactions, improve transparency, et cetera. But how can organizations ensure safe and robust blockchain transactions and networks? Suresh : Fantastic question. It’s interesting, that JPMorgan Chase is a private permission network. Now what does that mean? That means that every actor within our blockchain network is actually known to us. Now, it’s also interesting that hand in hand with that security aspect is the operational considerations of actually running a network. So we would need to be able to not only ensure security across the network, but we need to also ensure that we have transactional flow that meet the service level agreements between the various actors. Now, in a centralized private permission network, which is what Onyx is, is that JPMorgan Chase has taken the onus in terms of running the network itself. Now, people want to be able to say that they want to run their own nodes and they want to be able to ensure their own security, which is great if it’s unique and singular to themselves, but when you’re participating in a network, the weakest link in the chain actually becomes your greatest challenge. So all of the actors or all the nodes that are participating in our network would have to meet the same security and operational considerations that everyone else has. So when we pose that question to the participants in our network and say, “Listen, you have an opportunity to run your own node or you can have us do it for you,” most of them, 95% of them, want us to run their nodes for them. So I think that that’s one of the big challenges or one of the big aspects of a private permission network as opposed to a public network. Now, we’re increasingly seeing that there needs to be some integration across private permission networks and public networks. And again, when we have to integrate between these, we again run into classical problems or classical challenges, I should say, with the interconnected distributed platforms. But I think that this goes directly to the level of scale that we need to be at, especially within JPMorgan Chase, in order to be successful. Laurel: So there’s also the challenge of keeping up with emerging technologies. What are some of the emerging or advanced technologies that have enabled blockchain innovations? And this is clearly important to Onyx since it created a blockchain launch to focus on developing and commercializing those new applications and networks. Suresh : Absolutely. So within Onyx, we have three main lines of businesses and then we have Blockchain Launch, which looks at the hill beyond the hill in terms of evaluating new technologies. And we’ve done everything from looking at zero-knowledge proofs to trying to beam payments through a satellite back down to Earth and all of those types of things to create business value for our clients. So I would say that the two most exciting things, or there’s a third one which I think there’s a topic that we’ll broach later, but the two most exciting topics that we’ve talked about so far and we’re very excited about is around zero-knowledge proofs as well as artificial intelligence and machine learning. If you think about the network that we have right now within JPMorgan Chase for Onyx, the various participants within the network will eventually start to create enough data through the network effect that it might be very interesting to see what other data enrichment, data mining type use cases can come out of that, and we are only going to see an uptick in that as you start to expand the network and we start to get more scale as we add more use cases onto the Onyx network. Laurel: And so while we’re on that topic of emerging technologies, how does quantum computing and blockchain, how do those two technologies work together? Suresh : So the quantum computing piece and the blockchain piece are very collaborative and very symbiotic in nature. Now, if you think about the idea of utilizing quantum mechanics, it’s been around since the mid 1970s when it was first proposed that there was an algorithm that we can with very large numbers that can be factored using a theoretical quantum computing. It was pretty much in the background, and then suddenly in October 2019, Google announced that it achieved quantum supremacy by solving a problem in 200 seconds that would’ve taken thousands of years to be able to solve. And although that specific use case was sort of not specific to a business use case, the impact of that is very far-reaching because all of a sudden, it demonstrated that you could use quantum computing to actually create a mechanism that would impact pretty much every cryptographically secure transactional flow. So as we are looking through this, some of the things that we looked at in quantum computing was around looking at the quantum key distribution, looking at cryptographically secure vaulting, distributed identity. All of these we believe are key to the future of blockchain and actually impact even things as mundane as the topic that we spoke about before, which is around the cross-border transactional flow as well. Laurel: So while blockchain certainly seems to have the potential to shift the financial services industry, the need to focus on sustainability goals and follow regulations are also a major consideration. So how can innovations in blockchain be balanced with mitigating its emissions and environmental impact? Suresh : This is a question that we’ve been asked many times by our businesses in terms of how environmentally conscious are we? I would say that one of the big advances recently, especially within the Ethereum space, was the shift from proof to work to proof of stake. Now in proof-of-work systems, miners compete with one another to see who can problem solve the fastest in exchange for crypto rewards, and because of this, the proof-of-work systems take up a large amount of energy. Juxtaposing this is the proof-of-stake systems which rely on market incentives and validators, and in exchange for the right to add blocks, they remove the competition from the system. Now, because of this, the amount of energy that’s being used in a proof-of-stakes system goes down to 1% of the overall carbon impact of a proof-of-work system, so thereby, that shift alone was very important from a carbon emission perspective. Secondarily, within the Onyx system itself, we’ve shifted to a situation where we have set our gas fees to zero and the only compute is minimalistic in terms of just computing the business logic itself. And also, we’re using the BFT class of algorithms as well as RafT. Both are not compute intensive, aside from the business logic itself. Laurel: Thank you, Suresh. You’ve certainly given us a lot to think about. So looking to the future, what are some trends in technology that you’re excited about in the next three to five years? Suresh : So I think that we mentioned some of the topics before around quantum computing, artificial intelligence, machine learning. All of those I think are very important to us. Now, I would also say that the three to five year time horizon is probably too long. I think that when we speak in investment banking, we speak about an 18- to 24-month time horizon. We think that that’s probably a similar time horizon that we’re seeing in the blockchain space itself. So as we evolve, I think that the really interesting aspect of this is going to be where social networks and business networks overlap and how they organically evolve to support each other as we go forward, and how the payment space itself evolves in order to take advantage of this.
