Werbach: So if we're talking about the blockchain technology, if you are going to your Robin Hood account and you're deciding
00:00:05
whether to buy Bitcoin or to buy some meme stock, it's just another name, and you can think about it as an investment. But
00:00:11
that's not fundamentally revolutionary. Welcome to <i>The Ripple Effect</i>, the podcast that takes you on a
00:00:17
journey through the minds of Wharton faculty. I'm your host, Dan Loney, and in each episode, we'll be diving deep into the
00:00:23
inspiration behind the groundbreaking research that Wharton professors have conducted and exploring how
00:00:29
their findings resonate with the world today. Well, the conversations around cryptocurrency are surging right
00:00:36
now, and the path of what might happen with crypto investing and regulation in the next several years has turned many investors
00:00:44
thoughts to be very robust. But there is also other areas to focus on when you're talking about cryptocurrency, and that
00:00:51
is blockchain, the tool that makes a lot of these digital assets and digital payments possible. Pleasure to be joined
00:00:58
here in the studio today by Kevin Werbach, who's a Professor of Legal Studies and Business Ethics here at the Wharton
00:01:04
School. He's also Chair of the Legal Studies and Business Ethics Department. Great to see you again. It's been a while to
00:01:09
do this face to face. Always great to talk to you, Dan. - Thank you. You've done a lot of research and work in and around
00:01:16
blockchain. Where do you think we stand right now with its understanding, its adoption, its kind of place in the
00:01:24
overall business landscape? Blockchain technology has been around since 2008, when Satoshi
00:01:31
Nakamoto— and we still don't know who that is or was— issued a white paper developing the idea of Bitcoin. And Bitcoin's a
00:01:38
cryptocurrency. It's a form of digital asset, but it rides on this ledger technology called blockchain. And blockchain is
00:01:46
actually much more general in terms of its applications, as you mentioned. So we're something like 16 years in to
00:01:54
blockchain technology being widely available. It was actually built on even earlier foundations. And the question is
00:02:01
whether that's a long time or a short time. We see a great deal of interest. We see lots of experimentation. We see
00:02:09
certainly lots of trading activity around digital assets. We see building of distributed platforms on the vision of Web3,
00:02:18
a kind of distributed internet powered by tokens. We also see use of blockchain in payments, and we see companies
00:02:25
using it as a record-keeping technology for understanding information as it flows across their networks and between
00:02:33
companies. We don't yet see any real scaled use cases that are not predominantly powered by financial investment type
00:02:45
incentives. And so that's really the question of how far along we are. How do you think, then, we kind of take it from where it is now to
00:02:52
get to that point where there is more of a larger scale use of blockchain? It's not clear exactly what blockchain is going to be best
00:03:01
for. When I— when I talk about this—and as you said, I've been studying this for a decade at least— I always say there are
00:03:08
these different application categories, these different use cases. And it may be the case that the significant use case is
00:03:16
just as a— an investment asset, and that's really the one that has the most heft around it in terms of the activity. Or it may
00:03:22
be the case that when we look back 20 or 30 or 50 years from now, we say, "This is the new rails, the underlying technology
00:03:32
that powers the financial system as it evolved in the next stage." Or we might say something else. I don't think we should assume
00:03:38
that we know the answer to that. We should think about looking at applications and use cases as they develop. And then if it
00:03:47
actually is a better technology, if it really has advantages, then it will ultimately succeed in the market.
00:03:52
What's interesting is that as we try and find out more about what it can do and how it can help, it's really— it feels like it's kind
00:04:02
of up and down the spectrum in terms of who is trying to figure this out. You have conversations about this going on with the
00:04:08
Federal Reserve. Commentary by Chair Powell. You have so many different companies in different sectors that are kind of
00:04:13
wondering, is it something that works with how they run their operation? It truly is, it still feels like it's very much a
00:04:20
learning process right now. Yeah, I think people don't realize how foundational a change this
00:04:26
technology represents, if we're talking about the blockchain technology. If you are going to your Robin Hood account and
00:04:32
you're deciding whether to buy Bitcoin or to buy some meme stock, it's just another name, and you can think about it as an
00:04:38
investment. But that's not fundamentally revolutionary. The technology, though, really is. It's a decentralized ledger
00:04:46
technology that provides trust without any central entity that is the administrator that everyone relies on. And that's
00:04:54
incredibly powerful, and that's— has implications for all sorts of use cases. It has really significant implications for
00:05:02
finance in many ways. So that's why we have all these conversations. Unfortunately, though, it always tends to get
00:05:09
pulled back or influenced by this conversation about the speculative investments. And again, there's nothing wrong
00:05:14
with an interesting new investment asset class, but that's really the piece that everyone gets fixated on. But
00:05:21
then when you look at what's happening out there, we see really interesting growth of some of these other use cases as well.
00:05:26
Does the up and down nature of things like cryptocurrency have an impact on the mindset around the potential use of blockchain?
00:05:37
Oh, absolutely. And again, that's what I'm talking about, that people assume that it's inherent to blockchain that it is highly
00:05:44
volatile, and all about crazy, wild speculation. And also, we should mention fraud, scams, illicit activity. We saw the
00:05:53
collapse of FTX. Celsius, another company that collapsed in fraud. The CEO just plead guilty to criminal charges. So all of that
00:06:03
gets wrapped up into this. But when you actually talk about the ledger technology, it doesn't necessarily have that attribute.
00:06:11
So for example, one of the major applications of blockchain technology in finance is to create what are called stable
00:06:18
coins, and these are digital assets that are typically pegged to the US dollar or to some other stable reference point.
00:06:26
They're not volatile at all. Now they potentially could be risky if the assets that are backing them are not truly
00:06:32
stable, or they don't actually have the assets they claim to. So there's certain important regulatory issues. But those— those really
00:06:40
aren't at all about volatility. So I think it is important to differentiate it out when we're talking about something that's
00:06:46
purely investment versus something else. So you mentioned regulatory, and that's obviously another area
00:06:50
where you focus. And there's a lot of conversation right now around digital assets in general. We're going into a time
00:07:00
of switching administrations in the White House, and the belief is that maybe we're going to see a shift in terms of mindset.
00:07:08
When you think about regulation and all of these components around digital assets, where should we potentially land, do you
00:07:16
think, at some at some point? - Well, one starting point is that you look at history. Every time there has
00:07:22
been a major, unregulated, new kind of financial instrument that is accessible to lots of people, there have been horrible
00:07:32
abuses and fraud and crimes. Now that doesn't mean that those financial innovations were bad or should have been or were
00:07:38
prohibited, but that's why we need regulation. That's why we had the birth of things like the Securities and Exchange
00:07:44
Commission coming out of the Great Depression, where there was horrible abuse and fraud in financial markets. We see that
00:07:51
with digital assets. We see that with crypto, which doesn't mean that it should be prohibited. Unfortunately, what happened was
00:07:59
that the Biden administration was actually on its way to what I think was a really thoughtful and sensible approach to coming
00:08:07
up with what it called responsible digital asset regulation. So, you know, we want to
00:08:11
allow this technology to exist and promote the innovation, but ensure that there were the same
00:08:15
appropriate kinds of checks. If you, again, go to your Robin Hood account and you're investing in a digital asset, you have the
00:08:21
same kind of confidence that you're getting accurate information and the information you need, and the person on the
00:08:28
other side is not trying to scam you, as if you're buying an equity that's traded on the New York Stock Exchange. That makes
00:08:34
sense. What happened was, in the interim, we had the explosion of the crypto bubble and the collapse of things like FTX,
00:08:41
which really soured a lot of people in and around the US government at that time in this whole space. They really, I
00:08:49
think, over indexed on protecting against any harms happening. Those are true of the banking regulators as well. And
00:08:56
unfortunately, didn't differentiate out between the firms that were really shady and questionable, and the ones that
00:09:04
were saying, "Tell us how to comply. Tell us how to— we don't understand. It's really hard to map all of the existing rules
00:09:10
onto this new technology. We want a path to clarity." They didn't make that distinction, and as a result, you got a
00:09:17
backlash from certain loud, powerful voices in the industry and in the venture community, who eventually seized on Donald
00:09:27
Trump as the one who would bring them a new, less regulatory environment for crypto. And they started supporting his campaign.
00:09:35
Not the whole industry, but some very powerful figures. And they are now part of the new administration, and will very
00:09:43
certainly take this in a very different direction. So then are we, to a degree— should we,
00:09:50
with the growth that we have seen in terms of the pricing of things like Bitcoin and Ethereum
00:09:56
and some of the other assets in recent months, should we believe that there is an unbelievable strength that's
00:10:04
kind of building up around cryptocurrency, or is it still kind of a wait and see, because there is this influence that's
00:10:12
kind of pushing things forward? I don't give investment advice, and especially in this space
00:10:17
where, you know, there are so many uncertainties. I think it's really easy to come up with simple explanations. This— this
00:10:24
decision happened, and then the price of Bitcoin moved this way. When you actually understand how the Bitcoin market works,
00:10:31
actually very highly concentrated, actually fairly illiquid. There has been, historically, lots of evidence
00:10:36
of market manipulation, and it's— it's a kind of a meme currency. People are buying in because of their belief about
00:10:43
the potential of the technology. And again, that in and of itself, doesn't mean that it's not an investment that you can
00:10:49
make money on. But it's really not a simple answer that this happened yesterday and the price went up or down today. You even
00:10:57
look at the crypto market behavior after the Trump victory. Bitcoin went up a lot. A few of the other ones, like
00:11:05
XRP, which was associated with this company, Ripple, that had a lawsuit against the SEC and so forth, that went up a great
00:11:13
deal. Ethereum, which is the second biggest cryptocurrency, barely budged after Trump's election. Many of the other
00:11:20
coins, at least right after the initial time, didn't seem to have a big impact. So look, this is— again, these are investment
00:11:28
assets. There are ways to invest thoughtfully. There are different ways to come up with a— an understandable valuation.
00:11:36
And certainly it is affected by— by the vibe, certainly is affected by regulation. But I think people too often just assume
00:11:43
that that's a simple equation when it really isn't. Well, and for a while there, there was a conversation about,
00:11:49
you know, whether or not we were going to see digital assets used as currency by different countries. And there were
00:11:55
attempts to do that. But then you hear, you know, the commentary from Chair Powell about, it should be more tied to
00:12:03
gold than it should be traditional currencies. And so are we past the point, do you think, of— of believing that it's
00:12:11
something other than really an investment of a, you know, of that type of nature?
00:12:17
That's different. That's what are called Central Bank digital currencies, or CBDCs. So going back to what I said
00:12:22
before, blockchain is the underlying technology. You can use it to issue these tokens which are not really backed by
00:12:29
anything, and are volatile, and essentially are investment assets— or they're used for payments. Bitcoin itself, the
00:12:34
whole idea is that it's a store of value, independent of governments, and it's a new kinds of mean of— means of
00:12:40
payment. Or you can think about having them be stable assets, either privately issued stable coins or publicly issued digital
00:12:49
currencies. China has issued a central bank digital currency. It's not— none of these are on exactly the same kind of totally
00:12:57
decentralized blockchain technology as assets like Bitcoin and Ether, but they have a similar kind of ledger
00:13:03
technology. The European Union is fairly far along in a digital euro. The UK is somewhat far along. They're still skeptical,
00:13:11
but trying to come up with the foundation for a digital pound, and the Federal Reserve has done a good deal of research on a
00:13:17
digital dollar. But it is true, they have been fairly skeptical that we should implement this. The question is always, really,
00:13:26
what problem does it solve? So much of the currency is already digital. - Yeah.
00:13:30
And what problem does it solve that these private stable coins, which create this new decentralized platform are
00:13:37
not already solving in the marketplace? Where do you think, then, we head with blockchain and that technology
00:13:45
in terms of kind of building the framework so that it becomes, you know, something greater than what it already is right now?
00:13:52
One thing is that the technology is maturing. For a while, there were serious issues about scalability. There's been a lot
00:13:59
of progress on that. There's been a lot of progress on privacy and other aspects. There is also development in that
00:14:08
marketplace, once you get beyond Bitcoin, which is kind of a unique thing. There are questions about different
00:14:15
platforms. Ethereum, which for the longest time has been the second most valuable and the most prominent digital asset for
00:14:22
these other kinds of uses of blockchain. There are other platforms like Solana that have certain advantages that seem to
00:14:29
be maybe catching up. So there's— there's all of these questions about maturation. But— but I think ultimately, it's
00:14:34
just a matter of, first of all, we do need a good, clear regulatory environment so that we can put that to the side and
00:14:41
we can address these appropriate concerns, the concerns about investors, the concerns about fraud and crime and sanction
00:14:47
violations, very real issues that need to be addressed. And it's not just a matter of deregulating. It's a matter of
00:14:53
actually regulating and having a clear framework, which will almost certainly take legislation to address these
00:14:59
issues. We need that first. And then we just need time. Because again, we're talking about here, just to take
00:15:05
one of these use cases, use for payments in the financial system. This is re-architecting the pipes of global finance.
00:15:13
There are trillions and trillions of dollars at stake here. This is not something that's going to happen
00:15:18
overnight. I believe it's going to happen. It's just fundamentally a better technology than the accumulation
00:15:25
of things that we have now underlying the financial system. But that's— that's a period of many years to really realize
00:15:32
that potential. Great to see you again, Kevin. - Thanks very much. My pleasure. Kevin Werbach, Professor of Legal Studies and Business
