A former blockchain division head at Ernst & Young (EY) has gone public about his misgivings regarding the much-hyped potential of corporate blockchain.
Angus Champion de Crespigny, who graduated as an engineer and who has worked in cybersecurity, data analytics, regulatory compliance, and technology worked at Ernst & Young for ten years and ran the company’s blockchain division specializing in finance.
He began studying Bitcoin in around 2013, and, according to an interviewer at Barron’s, “was excited about the technology at first…” but decided to leave the EY after becoming, “…extremely skeptical about blockchain’s usefulness for businesses.”
Despite Champion de Crespigny misgivings, Ernst & Young, nonetheless appears to be continuing with the tech and told Barron’s:
“(W)e continue to see areas in financial services institutions where permissioned or private blockchains really can provide value.”
“I could see how exciting this could be, but also what sort of a regulatory minefield people were walking into.”
Like many approaching the subject, he was enthused:
“Yeah, I was optimistic. It would be silly for me to say otherwise. My views were aligned with a lot of the common views at the time.”
But over time, and through much practical consideration, he realized adapting a tech designed to “run automatically” without a single point of oversight in a corporate environment (which necessitates and benefits from oversight) was proving not only complex and costly, but also unnecessary:
“Once you can get all of those stakeholders together, you generally form some sort of trusted central entity anyway. If you managed to do that coordination, which is the difficult thing, there is technology that you can use that is far easier… Just a distributed database, which is faster.”
“That is a little bit like this industry. If we could create one big blockchain that everyone is on, that isn’t owned by anyone, that works perfectly, if everyone agrees on the standards—then it would be a great setup. In reality the process to get there is just incredibly, incredibly complicated.”
“The reason (a private distributed database) is faster and the reason it is more efficient is because it is all built around a central controlling entity…Typically, as it evolves, you end up having to coordinate everyone. And if you can coordinate everyone, then there is often a better technology to use than a blockchain.”
“I won’t comment on specific companies, but there is a certain amount of headline chasing. I think once you have spent a certain amount of money with this you better have something to show for it…”
“The traditional ones are [ Microsoft ’s ] SQL Server and Oracle. Any traditional enterprise database can be set up to be distributed in that way. This is technology that has been around for a long time. People are now being sold a dream that a blockchain is going to be easier to do all of this, and I just don’t think that’s accurate.”
Champion de Crespigny questioned Gartner’s claim that blockchain would be worth $3.1 trillion-plus to businesses in 2030:
“I didn’t see where private blockchains could create any value to business. So I am not sure how they assess those numbers. The thing is at the 20,000-foot level, it sounds like it makes sense, because you get told this could automatically reconcile and get rid of errors. When it comes down to the technical nuts and bolts, how does it actually do that? But most errors are at the inputs and outputs of the systems. I haven’t seen anyone who has been able to tell me how to actually do it. I think there is a lot of strategic thinking and buzzwords and not enough hands-on technical knowledge.”
“I think we have a habit in the West of being rather Western-centric and not realizing that there are a significant number of people in the developing world who don’t trust their local government, at least not enough to store all of their money in that local currency. Having some sort of digital alternative is very beneficial to them.”
