The rise of decentralized finance: A comprehensive overview

Almost all aspects of financial transactions—banking, trading, investing, and lending—are monitored by centralized governing bodies. Clients must go to financial intermediaries and go-betweens to access loans, financial instruments, and insurance policies. 

In the US, for example, banks are regulated by the Federal Reserve. 

Meanwhile, the Securities and Exchange Commission, or SEC, manages financial markets and brokerages. Lastly, the insurance commission oversees insurance providers. Over time, all the rules that were set on them could be amended by the US Congress. 

As a result, customers, borrowers, policyholders, and investors have to walk along limited, narrow paths to access financial services directly. They cannot simply pass through middlemen, banks, financial market exchanges, and lenders, all of whom earn a portion of financial transaction earnings. Put simply, we must always pay to play. 

However, with decentralized finance (DeFi), businesses and private individuals can challenge the status quo set by the current centralized financial system. Through DeFi, we can bypass these financial middlemen, allowing peer-to-peer exchanges. 

Unsurprisingly, the cryptocurrency market’s promise of a decentralized financial system has captured the world’s imagination. And even if it has yet to achieve its goal, many people globally are optimistic about its trajectory. 

That is why DeFi is expected to play an integral role in achieving financial freedom and revolutionizing business transactions. It continues to emerge, supported by the peak of fintech and digital revolution today. 

This article will give a comprehensive view of DeFi and its popularity. We will also cover its role in transforming business and personal finance. 

What is decentralized finance? 

Decentralized finance or DeFi is a rising financial system built on secure distributed ledgers, similar to those used in the crypto market, particularly Ethereum (ETH). 

In short, DeFi uses blockchain technology and smart contracts to track financial transactions. This creates a permissionless, seamless, open, and transparent financial system. 

Unlike traditional or centralized financial systems, DeFi does not rely on banks, brokerage firms, lenders, and other financial intermediaries. 

Instead, it leverages decentralized networks to allow peer-to-peer transactions without requiring the approval of different financial intermediaries. This means it democratizes global financial systems by replacing centralized institutions with peer-to-peer relationships that enable them to access a full range of financial services directly. These include loans, banking, and investing. 

In the US, the Fed and SEC set the rules for centralized financial systems governing banks and brokerages. Consumers rely on them to access capital and banking services directly. However, with DeFi, financial democracy permits individual transactions without paying intermediaries to transact. 

DeFi: The New Normal 

DeFi’s core premise is the absence of centralized authority that dictates financial operations. It’s an opposite approach to the traditional financial models for centralized finance (CeFi) or fiat money. With CeFi models, there is a body that can manage the flow of financial transactions. This body also manages the custody of assets. 

With DeFi, authority is decentralized to provide more power to individual investors and clients. All financial transactions, whether banking, lending, or trading, take a peer-to-peer approach. For asset custody, individual traders can control their asset management. 

This is the same as in the crypto market, where traders control their private cryptographic encryption keys. Thanks to blockchain technology that supports smart contracts to enable financial transactions. 

Again, DeFi removes the essential elements of CeFi, and here’s how it works. Suppose you plan to open an online savings account to put your money and earn a 1.0% interest. In CeFi, the bank lends it to a borrower at 3.0% interest, leading to bank earnings of 2.0%. 

In DeFi, individuals can lend their savings directly to borrowers at the same interest rate. They earn that 3.0% loan yield directly. You may have been doing this when you lend to your friends using digital services like PayPal (PYPL). 

But in reality, you never did. It is because users should link their debit or credit cards to PYPL, making their peer-to-peer (P2P) transactions reliant on CeFi. In short, DeFi allows P2P transactions in any app without relying on financial intermediaries. 

DeFi’s Real-World Scenario Uses 

DeFi has started penetrating a wide range of simple and complex financial transactions. Through apps called DApps and programs called protocols, DeFi can handle transactions in the two primary coins, Bitcoin (BTC) and Ethereum (ETH). 

Although BTC is more significant and more popular, ETH offers more real-world scenario uses since it’s built on blockchain technology. It makes ETH applicable to various uses. So, most DApps’ and protocols’ landscape relies on ETH-based codes. These are some notable ways DApps and protocols are being used today. 

Yield Farming and Harvesting

Yield farming and harvesting play an integral role in the DeFi ecosystem. They may offer retirees enticing opportunities to derive passive income and increase their retirement funds. Their core premise provides liquidity to traders by lending or staking their cryptocurrencies. It is most applicable for speculative investors, especially those who expect value appreciation in the long run. 

What makes these enticing is the potential yields, which can be much higher than in traditional bank accounts and bonds. Even so, we must understand that risks are higher in DeFi investments due to extreme volatility. 

As such, retirees must carefully research the market, diversify their portfolio, and assess their risk appetite and tolerance to optimize risk-reward management. 

On a lighter note, crypto returns have outweighed volatility over the years. These are much higher than in the stock market. The table below compares several cryptocurrencies to stock indices using the Sharpe Ratio. 

The Sharpe Ratio of all cryptocurrencies is higher than the stock market. Despite their high standard deviation, this shows higher chances of gaining in the crypto market. Buying and selling cryptocurrencies may become a good source of earnings for retirees. 

Even businesses may utilize it to diversify their investments and define employee benefit plans. This makes yield farming and harvesting a potentially profitable investment vehicle. 

This is essential for retirees when they leave their jobs. The investment choice is already theirs. They can have a 401k IRA rollover if they want to invest their retirement fund themselves. Hence, yield farming may be considered an option to generate gains in the long run. 

DeFi allows speculative investors to lend their crypto holdings and generate big rewards or earnings when DeFi borrowing platforms pay them in exchange for agreeing to rapid loan appreciation. As the crypto market heats up, the possibility of expansion and value appreciation is high. 

E-wallets 

DeFi developers have started to create e-wallets that can function independently without requiring the linking of bank accounts. These can give traders access to cryptocurrency trading, bank-free lending, independent asset custody, and blockchain-based games. 

Non-fungible Tokens 

Non-fungible Tokens (NFTs) create digital assets using non-tradable assets. Notable examples include the first tweet on Twitter and videos of slam dunks. In short, NFTs make an uncommodifiable object a commodity. 

Flash loans

Flash loans are crypto loans wherein borrowing and repaying funds happen in the same transaction. While it sounds counterintuitive, borrowers can make money by entering into smart contracts without third parties involved. 

With these contracts, transactions can be executed where users can borrow funds and get repaid instantly. If the transaction is unexecuted, the funds go back to the lender. If you profit, you can keep it minus any interest payments and fees. Hence, flash loans are comparable to decentralized arbitrage. 

Decentralized Exchanges 

Many crypto users today trade on centralized exchanges, such as Coinbase and Kraken. With Decentralized Exchanges (DEXs), individuals can independently facilitate P2P financial transactions and control their money. 

Stablecoins 

While cryptocurrencies are notorious for their extreme volatility, stablecoins may stabilize crypto values by tying them with non-crypto items, such as currencies. 

Traditional Transactions 

Anything from traditional financial transactions, such as payments, insurance, investment trading, borrowing, and lending, is now taking place with DeFi. 

DeFi’s Risks and Downsides 

DeFi is an emerging trend that may come at great risk since it is an innovation that has yet to be tested often by prolonged or mass use. There may be some risks that are yet to be identified and addressed. 

Additionally, various authorities scrutinize its systems and look for ways to regulate them. These are some of the risks and downsides associated with it. 

Hacking and security threats 

While anonymity is one of the critical features of the crypto market, this aspect can be a channel for fraudulent activities and hacking. A blockchain is almost impossible to alter. 

Yet, other aspects of DeFi are exposed to hacking risks, which can create ways to steal funds. Many of DeFi’s potential use cases rely heavily on software systems susceptible to hacking. 

Collateralization 

Collaterals are assets used by borrowers to secure loans. For instance, when you get a mortgage, the collateral is the home you are buying. Note that almost every DeFi lending transaction requires collateral equivalent to or higher than the principal value of the loan. Hence, it may limit the number of individuals qualified for many DeFi loans. 

Private key requirements 

Users must secure their wallets to store cryptocurrencies using private keys. These are long and unique codes accessible only by the owner. If they lose their keys, they also lose access to their funds because lost private keys are unrecoverable. 

Lack of consumer protection 

DeFi has captivated the world due to the absence of regulations and mediators. Yet, it also means a lack of solution in case of a foul transaction. In CeFi, the FDIC can reimburse up to $250,000 per account if a bank becomes insolvent. 

Additionally, banks must hold a particular portion of their capital as reserves to maintain liquidity and allow clients to withdraw their money. No similar protection can be seen in DeFi. 

Key Takeaways 

The decentralized financial (DeFi) system promises investors, customers, lenders, and borrowers a rosy future. It shows enticing potential to expand and generate earnings in the long run. Yet, one should not discount the risks associated with it as it remains under-tested. Interested individuals must research it thoroughly before stepping into it.
