What is Defi and why is it important in 2023?

Decentralized Finance, or “DeFi” for short is a topic that has gained a lot of attention in the crypto space and is a new way of thinking about finance. Built on blockchain technology and decentralized networks, DeFi is a financial ecosystem. It is open, transparent, and accessible to anyone with an internet connection. In this article, we will guide you through what is Defi and everything you need to know about it.

So what basically is DeFi?

DeFi is a financial system which makes economic products and assets available on a public ledger of sorts. DeFi eliminates the need for intermediaries such as banks, which allows individuals to take control of their own financial lives, and access services like lending, borrowing and investing directly. Additionally, DeFi enables the creation of new financial instruments and markets that were previously impossible. As a system, it essentially works on the principles of decentralization and has a permissionless characteristic.

So to put it in simple terms, DeFi is a financial system that works on a specific chain technology and allows anyone to access financial services. It works as a catalyst for the development of new monetary mechanisms and markets. DeFi enables peer-to-peer financial interactions and doesn’t require any form of government-issued ID, Social Security number, or proof of address.

How does DeFi work exactly?

Decentralized Finance (DeFi) works by using blockchain technology and smart contracts to facilitate transactions and provide financial services. Integration of both these concepts in a seamless manner is essential to provide the best possible economic mechanism for DeFi.

Blockchain networks come into play in a way that the building of the DeFi platforms happens on top of such networks.
For example Ethereum. On the other hand, the smart contract gives DeFi a working framework. They use smart contracts to create decentralized financial applications. These applications can provide a wide range of services, including lending, borrowing, trading, and insurance.

Let’s look at an example. A DeFi lending platform would allow individuals to lend and borrow money from each other, using smart contracts to automatically manage the terms of the loan, such as the interest rate and repayment schedule. Similarly, a DeFi trading platform would allow individuals to trade digital assets, such as tokens, using smart contracts to automatically execute the trades.

DeFi platforms also often work on a concept called liquidity pools. In this mechanism, the pooling of a group of assets happens and it works to provide liquidity to the platform users. Users can deposit assets into the pool and earn interest on them, or borrow assets from the pool with a certain interest rate, also contributing to the liquidity of the platform.

Why is DeFi important in crypto?

Decentralized Finance (DeFi) is important for several reasons:

Financial inclusion:

As mentioned earlier, one of the key benefits of DeFi is that it ensures users get authority over their financial assets. This not only gives individuals more control over their financial lives, but it also has the potential to increase financial inclusion for those who have experienced exclusion from traditional financial systems.

Decentralization and Innovation:

By removing the need for intermediaries and centralizing authorities, DeFi can help to create a more decentralized financial system. This system aims at not receiving governed from a single authoritative figure. Instead, it pushes to be community-led and as a result more attainable to all kinds of people. This opens up new opportunities for investment and allows for the creation of markets that were previously impossible.

Transparency and security:

The Blockchain technology on which DeFi works makes sure that DeFi transactions remain transparent and secure in every way possible.


Smart contracts, a key component of DeFi, allow for the automation of the terms of financial transactions. This makes the process more efficient and secure. This can help to reduce costs and increase access to financial services for individuals and businesses.

To conclude

In conclusion, Decentralized Finance (DeFi) is a rapidly evolving field that has the potential to revolutionize the way we think about finance. However, DeFi is still a relatively new field and there are many challenges that we need to address. Security is a major concern, as the decentralized nature of DeFi makes it vulnerable to hacking. It could also fall victim to other forms of cybercrime. Additionally, regulation is an ongoing issue, as governments around the world are grappling with how to regulate this new technology.

Despite these challenges, the potential benefits of DeFi are too great to ignore. DeFi has the potential to democratize finance and bring about a more inclusive and transparent financial system. As technology continues to evolve, it will be important for the community to recognise these challenges. Members will have to work together towards building a sustainable and secure DeFi ecosystem. With the world moving towards digitalization, DeFi has great potential to become the future of finance.
