How DeFi Works

Understanding DeFi: Future of Finance

Decentralized Finance, or DeFi for short, is a revolutionary concept that offers financial services on public blockchains, fundamentally changing how we perceive and interact with money and financial institutions. DeFi encompasses various services such as lending, borrowing, trading, and earning interest, much like traditional banking. However, it operates without intermediaries, making it faster, more accessible, and more transparent. Embracing the ethos of cryptocurrency, DeFi is a globally accessible platform that is reshaping financial inclusion and empowerment.

Core Concepts

Decentralized Finance (DeFi)
- In traditional finance, services are typically controlled by centralized entities like banks. In contrast, DeFi operates on blockchain technology, allowing individuals to access financial services without intermediaries, broadening access and reducing costs.
Smart Contracts
- These are self-executing contracts with the terms of the agreement directly written into code. In traditional finance, contracts often require intermediaries for enforcement, whereas in DeFi, smart contracts automate enforcement, minimizing human error and increasing efficiency.
Decentralized Exchanges (DEXs)
- Unlike traditional exchanges that require a central authority, DEXs enable peer-to-peer transactions without custodial services. This aligns with the DeFi principle of empowering individual users rather than central institutions.
Stablecoins
- Traditional finance often relies on fiat currencies, which are stable but susceptible to inflation. Stablecoins in DeFi provide a digital representation of these currencies, allowing users to transact digitally without volatility while still gaining the benefits of blockchain, such as transparency and speed.
Yield Farming
- This DeFi term refers to the practice of lending or staking crypto assets to earn returns. Traditional finance features less flexibility with interest on savings, whereas yield farming offers potentially much higher returns, albeit with greater risks.
Collateralization
- In traditional lending, collateral protects lenders against default. DeFi amplifies this with concepts like over-collateralization, meaning you must provide more collateral than the loan amount, ensuring loans are backed securely in a transparent manner.
Flash Loans
- These are unique to the DeFi space—instant loans to be taken and paid back within a single transaction block. Traditional banks don’t offer such quick access to funds without extensive credit checks.

Understanding these concepts sets the foundation for newcomers to navigate and appreciate the transformative nature of DeFi and its overlap with cryptocurrency.

Examples

In the lesson, there are references to several platforms and concepts integral to DeFi, such as Yearn.finance and synthetic asset protocols. While no specific graphs or charts were mentioned, envisioning a visual that compares transaction times between traditional financial systems and DeFi operations would be valuable. A comparison chart could vividly illustrate the stark contrast in efficiency.

Hypothetical examples:

Traditional Loan vs. DeFi Loan: A traditional bank loan might take several days for approval, while a DeFi loan could be secured within minutes, providing instant access to necessary funds.
Trading with a DEX: Instead of waiting for hours or days for trades in traditional finance, a user can execute trades on a DEX in real-time, reflecting immediate market movements.
Yield Farming vs. Savings Accounts: Instead of a savings account earning minimal interest, one can place assets into a yield farming protocol to earn significantly higher returns, although with associated risks.

Real-World Applications

Historically, DeFi has transformed how individuals engage in financial transactions, leading to a 2020 boom in decentralized applications (dApps). Specifically, Uniswap has thrived as a DEX, allowing users to trade without intermediaries. As traditional markets grapple with inefficiencies, DeFi provides clear, actionable solutions for a faster and more transparent financial system.

Cause and Effect Relationships

The transition from traditional finance to DeFi has repercussions on how transactions are conducted. In traditional finance, delays and bureaucracy impede transactions, while in DeFi, instant execution drives market dynamics. This shift to decentralized platforms hints at a future where financial services are democratized, and individual sovereignty over money is fully realized.

Challenges and Solutions

DeFi faces several challenges, such as smart contract vulnerabilities, which traditional finance does not typically experience. Unique solutions include enhanced auditing of smart contracts and developing more robust decentralized protocols. A common misconception is that DeFi is entirely risk-free; understanding the potential instability of blockchain technology and market factors is critical for newcomers.

What is DeFi? DeFi is short for Decentralized Finance, and it’s an umbrella term used to refer to any financial services on public blockchains. DeFi allows you to do pretty much everything that a bank would, such as earn interest, buy insurance, lend or borrow, trade assets or derivatives, and so on.

But unlike traditional finance, in theory, DeFi could work faster. It doesn’t ask you to deal with paperwork, nor does it rely on authorities like a bank or government to control everything. As is the case with crypto, DeFi is global, peer-to-peer, pseudonymous, and open to everybody. DeFi Financial Instruments DeFi has its own financial instruments which make it stand apart, such as the Universal Market Access, a protocol for smart contracts on Ethereum. This is a synthetic asset protocol that allows anyone

to recreate traditional financial products, exotic crypto-based products, and more. Yearn.finance is an aggregator meant to maximize profits through yield farming. But DeFi also has the same components as the already existing financial ecosystem, meaning it needs stable currencies and a large variety of use cases.

One of the most important features of DeFi are Decentralized Exchanges, or DEXs. A DEX lets people trade digital assets in a non-custodial way, without having to rely on the services of a third-party service provider or intermediary such as a bank. We have an entire video about DEXs if you’re interested in finding out more about them.

DeFi uses stablecoins and services such as crypto exchanges and lending and borrowing services. Smart contracts are responsible for the framework needed for DeFi apps to function, as they encode the terms and activities needed for these services to work.

As an example, we can say that a smart contract code has a specific code that creates the exact terms and conditions of a loan between two individuals or entities. In the case that some terms or conditions aren’t met, collateral can be liquidated. This happens completely automatically with the help of a specific code. Unfortunately, liking this video cannot also happen automatically.

So, if this video cannot also happen automatically, so if you’ve enjoyed it so far, please let us know. Thank you. DeFi vs. Traditional Finances There are several things that stand in direct opposition when we compare DeFi with traditional finance, with the most important one being the fact that DeFi allows you to hold on to your own money, while in traditional finance, your money is always held by a company.

In DeFi, a transfer of funds can last only a couple of minutes, no matter the amount you are sending, even if there is the equivalent of millions of dollars involved. In traditional finance, a payment between different banks can take several hours to be processed, and moving large amounts of money through banks can be a very difficult process.

DeFi markets are always open, while traditional finance means that the market gets closed since employees need their break too. In DeFi, transaction activity is anonymous, while in traditional finance, your financial activity is tightly connected to your identity. Additionally, DeFi is open to literally everybody, while you must fill out an application in order to use conventional financial services.

Also worth mentioning is the fact that DeFi is built on transparency, which means that anybody can check the history of a product and its data, how it works, etc. Traditional financial institutions are close to the public, as only the bank and the tax administration are allowed to see loan history and the management of such assets.

DeFi Advantages and Risks DeFi comes with certain advantages, such as not having to deal with human error as smart contracts take charge. It also allows you to receive a crypto loan using only a few clicks, anytime during the day or night, allows you to receive a crypto loan using only a few clicks, anytime during the day or night, unlike the services of a bank.

We have a video about flash loans, which will offer you all the necessary information. Furthermore, DeFi uses permissionless operation. Instead of waiting for approval from your bank to withdraw any sum of money, DeFi lets you do this without permission. But of course, DeFi has its own drawbacks, such as uncertainty. For example, in the case that a blockchain hosting a DeFi project is not stable, the project won’t be stable either.

Scalability is another problem for DeFi, since in the case that a blockchain is crowded, transactions will take longer to be confirmed and they also become more expensive. If a smart contract has a flaw in its code, there is a chance funds will be lost. Other problems DeFi has to solve are over-collateralization and low interoperability. Conclusions DeFi is an all-encompassing term that refers to transactions happening on a blockchain.

With DeFi, you can do most of the things that one can do with a bank, like borrow, lend, earn interest, trade assets and derivatives, etc. The difference stems from the fact that DeFi is global, peer-to-peer, anonymous, does not use a centralized system, and is open to all. Meanwhile, the risks of a bank blocking your account or putting an embargo over it for various reasons are much higher.
