Defi - Crypto Currency

Decentralized finance, also known as DeFi, uses cryptocurrency and blockchain technology to manage financial transactions. DeFi aims to democratize finance by replacing legacy, centralized institutions with peer-to-peer relationships that can provide a full spectrum of financial services, from everyday banking, loans, and mortgages, to complicated contractual relationships and asset trading.

Centralized Finance Today

Today, almost every aspect of banking, lending, and trading are managed by centralized systems operated by governing bodies and gatekeepers. Regular consumers must deal with a raft of financial middlemen to access everything from auto loans and mortgages to trading stocks and bonds.

In the U.S., regulatory bodies like the Federal Reserve and Securities and Exchange Commission (SEC) set the rules for the world of centralized financial institutions and brokerages, and Congress amends the rules over time.

As a result, there are few paths for consumers to access capital and financial services directly. They cannot bypass middlemen like banks, exchanges, and lenders, who earn a percentage of every financial and banking transaction as profit. We all have to pay to play.

The New Way: Decentralized Finance

DeFi challenges this centralized financial system by disempowering middlemen and gatekeepers and empowering everyday people via peer-to-peer exchanges.

“Decentralized finance is an unbundling of traditional finance,” says Rafael Cosman, CEO, and co-founder of TrustToken. “DeFi takes the key elements of the work done by banks, exchanges, and insurers today—like lending, borrowing, and trading—and puts it in the hands of regular people.”

Here’s how that might play out. Today, you might put your savings in an online savings account and earn a 0.50% interest rate on your money. The bank then turns around and lends that money to another customer at 3% interest and pockets the 2.5% profit. With DeFi, people lend their savings directly to others, cutting out that 2.5% profit loss and earning a total 3% return on their money.

You might think, “Hey, I already do this when I send my friends money with PayPal, Venmo, or CashApp.” But you don’t. You still have to have a debit card or bank account linked to those apps to send funds, so these peer-to-peer payments still rely on centralized financial middlemen to work.

DeFi Runs on Blockchain

Blockchain and cryptocurrency are the core technologies that enable decentralized finance.

When you make a transaction in your conventional checking account, it’s recorded in a private ledger—your banking transaction history—is owned and managed by a large financial institution. Blockchain is a decentralized, distributed public ledger that records financial transactions in computer code.

When we say that blockchain is distributed, all parties using a DeFi application have an identical copy of the public ledger, which records every transaction in encrypted code. That secures the system by providing users with anonymity, plus verification of payments and a record of asset ownership that’s (nearly) impossible to alter by fraudulent activity.

When we say blockchain is decentralized, there is no middleman or gatekeeper managing the system. Transactions are verified and recorded by parties who use the identical blockchain by solving complex math problems and adding new blocks of transactions to the chain.

Advocates of DeFi assert that the decentralized blockchain makes financial transactions secure and more transparent than the private, opaque systems employed in centralized finance.

How DeFi Is Being Used Now

DeFI is making its way into various simple and complex financial transactions. It’s powered by decentralized apps called “Dapps” or other programs called “protocols.” Dapps and protocols handle transactions in the two leading cryptocurrencies, Bitcoin (BTC) and Ethereum (ETH).

While Bitcoin is the more popular cryptocurrency, Ethereum is much more adaptable to various uses, meaning much of the Dapp and protocol landscape uses Ethereum-based code.

Here are some of the ways Dapps and protocols are already being used:

  • Traditional financial transactions. Anything from payments, trading securities, and insurance to lending and borrowing is already happening with DeFi.
  • Decentralized exchanges (DEXs). Right now, most cryptocurrency investors use centralized exchanges like Coinbase or Gemini. DEXs facilitate peer-to-peer financial transactions and let users retain control over their money.
  • E-wallets. DeFi developers are creating digital wallets that can operate independently of the largest cryptocurrency exchanges and give investors access to everything from cryptocurrency to blockchain-based games.
  • Stablecoins. While cryptocurrencies are notoriously volatile, stablecoins attempt to stabilize their values by tying them to non-cryptocurrencies, like the U.S. dollar.
  • Yield harvesting. Dubbed the “rocket fuel” of crypto, DeFi makes it possible for speculative investors to lend crypto and potentially reap big rewards when the proprietary coins DeFi borrowing platforms pay them for agreeing to the loan appreciate rapidly.
  • Non-fungible tokens (NFTs). NFTs create digital assets out of typically non-tradable assets, like videos of slam dunks or the first tweet on Twitter. NFTs commodify the previously uncommodifiable.
  • Flash loans. These are cryptocurrency loans that borrow and repay funds in the same transaction. Sound counterintuitive? Here’s how it works: Borrowers have the potential to make money by entering into a contract encoded on the Ethereum blockchain—no lawyers needed—that borrows funds, executes a transaction, and repays the loan instantly. If the transaction can’t be executed, or it’ll be at a loss, the funds automatically go back to the loaner. You can pocket it if you make a profit, minus any interest charges or fees. Think of flash loans as decentralized arbitrage.

The DeFi market gauges adoption by measuring locked value, which calculates how much money is currently working in different DeFi protocols. The total locked value in DeFi protocols is nearly $43 billion.

Adoption of DeFi is powered by the universal nature of blockchain: The exact moment a Dapp is encoded on the blockchain, it’s globally available. While most centralized financial instruments and technologies roll out slowly over time, governed by regional economies’ respective rules and regulations, Dapps exist outside of these rules, increasing their potential reward and risks.

Risks and Downsides of DeFi

DeFi is an emerging phenomenon that comes with many risks. As a recent innovation, decentralized finance has not been stress tested by long or widespread use. In addition, national authorities are taking a harder look at the systems it’s putting in place, with an eye toward regulation. Some of the other risks of DeFi include:

  • No consumer protections. DeFi has thrived in the absence of rules and regulations. But this also means users may have little recourse should a transaction foul. In centralized finance, for instance, the Federal Deposit Insurance Corp. (FDIC) reimburses deposit account holders up to $250,000 per account per institution if a bank fails. Moreover, banks are required by law to hold a certain amount of their capital as reserves to maintain stability and cash you out of your account any time you need. No similar protections exist in DeFi.
  • Hackers are a threat. While a blockchain may be nearly impossible to alter, other aspects of DeFi are at significant risk of being hacked, which can lead to funds theft or loss. Decentralized finance’s potential use cases rely on software systems vulnerable to hackers.
  • Collateralization. Collateral is a thing of value used to secure a loan. For instance, when you get a mortgage, the loan is collateralized by the home you’re buying. Nearly all DeFi lending transactions require collateral equal to at least 100% of the loan’s value, if not more. These requirements vastly restrict who is eligible for many types of DeFi loans.
  • Private key requirements. With DeFi and cryptocurrency, you must secure the wallets to store your cryptocurrency assets. Wallets are secured with private keys, which are long, unique codes known only to the wallet’s owner. If you lose a private key, you lose access to your funds—there is no way to recover a lost private key.

How to Get Involved with DeFi

If you’d like to learn more about DeFi in a hands-on way, here are a few ways to get started:

Get a Crypto Wallet

“Start by setting up an Ethereum wallet like Metamask, then funding it with Ethereum,” says Cosman. “Self-custody wallets are your ticket to the world of DeFi, but make sure to save your public and private keys. Lose these, and you won’t be able to get back into your wallet.”

Trade Digital Assets.

“I recommend trading a small amount of two assets on a decentralized exchange such as Uniswap,” says Doug Schwenk, chairman of Digital Asset Research. “Trying this exercise will help a crypto enthusiast understand the current landscape, but be prepared to lose everything while you’re learning which assets and platforms are best and how to manage risks.”

Look into Stablecoins

“An exciting way to try out DeFi without exposing oneself to the price swings of an underlying asset is to try out TrueFi, which offers competitive returns on stablecoins (AKA dollar-backed tokens, which aren’t subject to price movements),” Cosman says.

The key to any foray into a new financial space is to start slow, stay humble, and don’t get ahead of yourself. Keep in mind that digital assets traded in the cryptocurrency and DeFi worlds are fast-moving and there’s significant potential for loss.

The Future of DeFi

From taking out the middleman to turning basketball clips into digital assets with monetary value, DeFi’s future looks bright. That’s why people like Dan Simerman, head of financial relations at IOTA Foundation, a DeFi research and development group, see both the promise and potential of DeFi as far-reaching, even though it’s still in the infancy of its capabilities.

Investors will soon have more independence, allowing them to “deploy [assets] in creative ways that seem impossible today,” Simerman says. DeFi also carries significant implications for the big data sector as it matures to enable new ways to commodify data, Simerman says.

But for all its promise, DeFi has a long road ahead, especially regarding uptake by the general public.

“The promise is there,” says Simerman. “It’s up to us to continue educating people about the potential, but we also need to keep working hard to build the tools that will allow people to see it for themselves.”
