Transcripts

Imagine a world where you can make trades,  deposit into a savings account or buy insurance,  

all without going through an intermediary  like a bank. That's the promise of DeFi,  

an umbrella term for a range of financial  products developed around the blockchain.

DeFi services have attracted  billions of dollars in funds,  

and proponents of the trend believe that  it will become an even bigger industry,  

rivaling the mainstream financial  institutions we’re familiar with today.

But the crypto winter of 2022 has  exposed cracks in the DeFi space.  

Billion-dollar projects went belly up, and  investors lost hundreds of millions of dollars  

to cybercriminals exploiting weaknesses in various  DeFi platforms. So what is DeFi exactly? And does  

it truly have a shot at becoming the future  of finance... or is it a road to nowhere?

The term DeFi – short for Decentralized Finance -  was first coined in a group chat on the messaging  

app Telegram in 2018. It was born out a  brainstorm amongst software developers,  

who were searching for a name for an  envisioned network of financial services  

built on blockchains – that would cut out the  middlemen typically involved in facilitating them.

With traditional finance, your funds are  stored and managed by centralized institutions,  

like banks. These firms make money by lending  out your cash and charging interest on top of  

the loans. They also collect various fees and  commissions for the provision of their services.

The modern payments system is riddled with  third parties who pocket a cut from daily  

movements of money. For example, retailers are  required to pay interchange fees – sometimes  

as high as 2% – every time a shopper  uses a credit card to make a purchase.

In the land of DeFi, new infrastructure is being  built that takes these banks and institutions out  

of the equation. Anyone with a computer can create  some software and launch their own financial  

service on a blockchain, meaning the barrier to  entry is much lower than in traditional banking.

Carol Alexander is a finance professor in the  

U.K. – and follows blockchain  and cryptocurrencies closely.

You could be a start-up with just a few people.

Whether it's taking people's  crypto and giving interest  

on that or peer-to-peer lending or  any type of project that you want.

One of the most popular applications of DeFi  is in lending. Users can lend out their crypto,  

just like a traditional lender does  with government-issued currency  

and earn interest; or they can borrow funds  by putting their tokens up as collateral.

Rates on these decentralized lending platforms are  

adjusted by an algorithm based on how  much demand there is for the loans.

All these exchanges are managed by  pieces of code called smart contracts.  

These are agreements written on  blockchain networks - most often on  

ethereum - which execute automatically  once certain conditions are fulfilled.

The proliferation of digital financial services  means individuals and companies can now expect  

to send and receive funds in a matter of seconds.  But the actual time it takes for those flows of  

money to settle can take much longer, often  hours, or a matter of days. For example,  

many banks use a third-party messaging  system called SWIFT for fund transfers.  

In DeFi, there’s no central authority  sitting in the middle of each transaction,  

meaning transactions can be accepted while funds  appear on the other side much more rapidly.

The real value in blockchains is that they are  like the motorway on which Web 3.0 is built.

The blockchain is the motorway, the  smart contracts are like the cars.  

You have different types of motorways for  different types of cars. Nonfungible tokens  

are a certain type of car, and then you have  other applications that are launching a new  

decentralized project where you can get  financing without going to a bank. The  

real value of the crypto coins that are  associated with each of the blockchains  

is that they’re like the fuel. Solana have a coin  called sol. Cardano have ada. Ethereum has ether.

DeFi didn't truly take off as an industry until  2020. That year, the sector saw exponential  

growth, with the total value deposited  into DeFi products climbing 30-fold.

But DeFi protocols aren’t covered by consumer  protection laws, making them riskier than products  

from regulated institutions. There are also doubts  about how decentralized DeFi platforms are, with  

regulators warning some services may be governed  by limited groups of influential entities.

It’s been called the “Wild West” of crypto  — hoards of computer programmers trying to  

bring traditional financial products such  as loans to the blockchain. Investors were  

enticed by the promise of earning sky-high  returns on savings in certain digital tokens.  

But as promising as the idea may sound,  it’s not all sunshine and rainbows.

As the value of the DeFi market  has risen, the number of criminals  

seeking to exploit it has also grown.  According to a report from Elliptic,  

overall losses caused by DeFi scams  and thefts totaled $12 billion in 2021.

I've come to a conference in London  where crypto companies and regulators  

have gathered to discuss efforts to clean up  the crypto industry. DeFi is a key theme here,  

as blockchain platforms start encroaching  on the realms of traditional finance.

Criminals are enterprising individuals.  They go where the money is.

Gurvais Grigg is global public sector CTO  at blockchain analysis firm Chainalysis,  

and a former assistant director for the FBI.

There's nothing inherently evil or wrong with DeFi  

or cryptocurrency and blockchain  itself. However, you can't have  

trillions of dollars move into a new asset  class and not attract criminals and grifters.

Jim Lee, chief of the Internal Revenue  Service’s criminal investigation division,  

says the U.S. tax agency is working closely  with the private sector to root out DeFi crimes.

The U.S. have hundreds of  crypto type investigations,  

federal criminal investigations  in some investigative status.

The speed at which crypto moves  or money moves these days,  

it's incredibly powerful to have  partnerships around the globe  

to ensure that we're, we're on top of  the criminals in a very small space.

Tell me about you know some of that  collaboration that’s now happening between  

the crypto world and DeFi but also  government agencies and regulators.

Partnerships are critical. Crypto moves so fast  these days. It's here, it's part of everyday life.

The collective partnership and relationships  around the globe, just make this space very small  

for criminals that want to try to take advantage  of it and our job is to make sure the ecosystem  

is stable.

Just like a car, every DeFi service is  ultimately the product of the labors of people  

who, by their very nature, aren’t perfect.

If a single part of the mechanism inside a vehicle  

doesn’t work as intended, it  becomes vulnerable to errors.

The same is happening in DeFi. And, in some  cases, those errors are proving costly.

Take blockchain bridges, for example. These  are tools that allow people to transfer  

tokens from one crypto network to another,  

at a fraction of the cost it typically  takes to make an on-chain transaction.

Instances of sloppy programming and software bugs  

have meant such bridges are becoming  increasingly vulnerable to attacks.  

More than $1 billion worth of crypto has  been lost to bridge exploits so far in 2022.

But the use of new software tools has made it  easier to trace crypto criminals’ ill-gotten  

gains. Companies are employing sophisticated  data science and machine learning techniques  

to analyze data on public blockchains  and track down fraudsters and thieves.

Unlike other forms of fraud in fiat, with  cryptocurrency in the blockchain, we have  

a record, right, and that transparency and  speed of accessing that record globally  

makes investigations of these types of  frauds accelerate over traditional finance.

DeFi faces an uphill battle if it wants to compete  with the titans of traditional finance. While the  

entire market is now worth over $60 billion, this  pales in comparison to the trillions of dollars  

held with incumbent financial institutions.  The implosion of controversial stablecoin  

venture Terra, among other mishaps, mean that  investors have also soured on crypto generally.

Stablecoin. It is plunging today.

So, is DeFi ready for prime time?

For now, the industry is still  very much in its infancy.  

Mistakes are being made, and scams remain a  common sight. But investment is being made  

to improve the security of DeFi platforms,  and governments are expected to usher in new  

regulations to wipe out bad actors and  ensure better protection for investors.

It will come through once we've got rid  of the cowboys. Some of these exchanges  

and some of these stablecoins are really  corrupting a very good system that I hope  

will provide a rebalancing of the  inequality of wealth through generations.
