Decentralized finance (DeFi): A beginner’s guide

DeFi is a burgeoning area of the cryptocurrency and blockchain industry that offers users exciting new ways to leverage the power and security of decentralized networks. This guide will provide an overview of DeFi, including its various applications and use cases.


The concept of DeFi was introduced in late that is the month of August 2018 as a way to describe the growing ecosystem of decentralized financial applications that are built on top of public blockchains.

The premise behind DeFi is simple – rather than relying on a central authority or third party to manage finances, DeFi leverages blockchain technology and smart contracts to automate transactions and enterprise processes in a secure, transparent, and trustless manner.

The overwhelming majority of value locked in DeFi applications is still concentrated on Ethereum, where these apps were originally built, despite the number of projects and platforms growing steadily in recent years.

How does DeFi work?

DeFi involves the use of smart contracts to enable peer-to-peer transactions. These smart contracts are effective computer programs that run on a blockchain and act as autonomous agents that can interact with other blockchain-based services and execute user commands. 

The use of these smart contracts allows for many different types of financial products and services to be built and delivered in a decentralized, trustless manner.

Decentralized finance has the potential to revolutionize the financial industry by reducing costs, increasing transparency, and improving efficiency. The use of blockchain technology also allows for a greater degree of privacy and convenience than traditional banking systems.

The Various Applications of DeFi

DeFi applications

DeFi has been used in a wide range of applications and use cases, including:

Borrowing and lending

The most common use case for DeFi today is lending and borrowing. The decentralized nature of these platforms means that they allow users to connect directly with one another, cutting out the need for centralized third parties, such as banks. Many DeFi lending applications utilize smart contracts to manage repayments and process other transactions automatically.

Trading and exchanges

Another key area of DeFi applications is trading and exchanges. The decentralized nature of these platforms means they are often more secure, efficient, and transparent than their centralized counterparts. The use of smart contracts can also facilitate a wide range of advanced trading strategies, such as automated hedging.

Savings and investment

DeFi is also being used to provide users with new and innovative ways to save and invest their money. The use of smart contracts allows these platforms to offer more transparent, fee-free investment options than traditional banks or investment firms. Some popular applications in this space include crypto asset management services like Compound, Finance, and Nuo Network, as well as decentralized prediction markets like Augur.


DeFi is also being used to facilitate the tokenization of real-world assets, such as securities and real estate. The use of blockchain technologies allows these assets to be represented through digital tokens that are held in smart contracts while providing greater transparency, security, and efficiency than traditional methods.


Finally, DeFi is being used in the gaming industry to create new types of digital assets and in-game economies. The use of smart contracts allows these decentralized games to offer features and functionality that cannot be achieved on centralized platforms. Some popular examples include Augur-based prediction markets, card trading services like Gods Unchained, and multiverse games like The Abyss.

Decentralized finance (DeFi) vs. centralized finance (CeFi)

DeFi VS CeFi

The comparison between DeFi and CeFi can be seen as a comparison between the new technology of blockchain and the old, established financial system. Centralized finance has traditionally been dominated by large banks and financial institutions that control large amounts of money, On the other hand, decentralized finance is built on cutting-edge technology that gives ordinary individuals the power to manage their own finances. Decentralized finance apps are designed to be more secure, transparent, and efficient than centralized alternatives, making them attractive to many investors and consumers.

Why does decentralized finance stand out against traditional methods?

Decentralized finance is preferable to traditional finance because it doesn’t require the financial bureaucracy to run. Decentralized apps are built on blockchain, which allows for fast and secure transactions without the need for a central intermediary. 

Using open-source code and smart contracts enables Decentralized Finance to be more transparent and efficient, giving it a competitive edge in today’s rapidly evolving financial landscape. Unlike centralized finance, decentralized finance can provide greater access to financial services for all members of society. DeFi offers an accessible and efficient alternative to traditional financial institutions for everyone.

Decentralized finance is growing more popular because it promotes transparency and openness, two qualities that are often lacking in traditional finance. Many investors are looking to get involved in DeFi and reap the benefits of this exciting new technology. 

However, much work must be done before DeFi becomes a mainstream alternative to traditional methods. Nevertheless, it is clear that it has the potential to transform the financial industry for the better.

Risks to consider before jumping into the world of decentralized finance

DeFi risks

One of the biggest risks associated with decentralized finance is security. The use of smart contracts and open-source code means that there is always a possibility for malicious actors to exploit vulnerabilities in these systems, putting users’ funds at risk.

Additionally, because DeFi relies on blockchain technology, it can be difficult to scale up to meet increasing demand. Blockchain architecture is often slower and less efficient than centralized alternatives, which puts pressure on developers to continuously improve and innovate in order to remain competitive.

Another risk associated with decentralized finance is that the technology is still relatively new, so it can be difficult for investors to know how reliable or stable these apps are. There may also be regulatory uncertainty around these platforms, as governments are still trying to understand how DeFi fits into the broader financial landscape.

Is it wise to invest in DeFi?

Decentralized finance, or DeFi, is an exciting new technology that has the potential to transform the way we think about money and finance. The key for investors and consumers looking to get involved in DeFi is to carefully weigh the risks against the potential benefits and make informed decisions that are right for their individual needs.
