What is DEFI And Why Did It Emerge?

Decentralized finance, commonly known as DEFI, has disrupted traditional financial services and brought forth a new wave of financial innovation. But what is DEFI, and why did it start? In this article, we will explore the origins, its key principles, and the driving forces behind its rapid growth. Along the way, we will provide real-world examples and delve into the various components that make up the ecosystem.

What is DEFI: The Core Principles

At its core, DEFI is a movement that aims to create an open, accessible, and transparent financial system built on blockchain technology, primarily the Ethereum network. By leveraging decentralized protocols and smart contracts, it eliminates the need for intermediaries such as banks, brokers, and other traditional financial institutions.

There are several guiding principles behind DEFI, which include:

  1. Decentralization: The platforms operate on decentralized networks, minimizing the risk of central points of failure and allowing for more democratic control over the system.
  2. Permissionless Access: Anyone with an internet connection and a digital wallet can access DEFI services, irrespective of their geographic location, financial status, or credit history.
  3. Transparency: The platforms are built on public blockchain networks, ensuring transparency and providing users with full visibility into transactions and platform operations.
  4. Financial Innovation: The ecosystem fosters a culture of innovation, enabling developers to experiment with novel financial products and services that cater to diverse user needs.

The Birth of DEFI: Unveiling the Origins

So, why did DEFI start? The origins of it can be traced back to the rise of cryptocurrencies like Bitcoin, which challenged the traditional financial system’s status quo. The launch of Ethereum in 2015, with its smart contract capabilities, further laid the groundwork for what is DEFI today.

The first project, MakerDAO, emerged in 2017, introducing a decentralized lending platform that allowed users to mint a stablecoin called DAI by collateralizing Ethereum. This project marked the beginning of the DEFI revolution, as it demonstrated the potential of decentralized platforms to replicate traditional financial services without relying on central authorities.

The movement gained traction in 2020, with the rapid growth of decentralized lending, borrowing, and trading platforms. This period, often referred to as “DeFi Summer,” witnessed a surge in the total value locked (TVL) in DEFI protocols, indicating increased user adoption and confidence in the DEFI ecosystem.

What is DEFI: Exploring the Ecosystem

The DEFI ecosystem comprises various platforms, protocols, and applications that provide a wide range of financial services. Some key components of the DEFI ecosystem include:

Decentralized Exchanges (DEXs)

DEXs are platforms that facilitate peer-to-peer trading of cryptocurrencies and tokens without relying on a centralized order book or intermediaries. Examples of popular DEXs include Uniswap, SushiSwap, and PancakeSwap.

Lending and Borrowing Platforms

In the DEFI space, lending and borrowing platforms enable users to lend and borrow cryptocurrencies without the need for traditional intermediaries like banks. Aave, Compound, and MakerDAO are well-known examples of DEFI lending and borrowing platforms.


Stablecoins are digital assets pegged to a stable reserve, such as a fiat currency or a commodity, to minimize price volatility. They play a vital role in the DEFI ecosystem by providing a stable medium of exchange and store of value. Examples include USD Coin (USDC), Tether (USDT), and DAI.

Yield Farming and Liquidity Mining

Yield farming and liquidity mining are practices that involve providing liquidity to DEFI platforms in exchange for rewards, such as interest, fees, or platform-specific tokens. Users can participate in yield farming and liquidity mining to generate passive income or to maximize their returns on investment. Popular platforms for these activities include Yearn.Finance and Curve.

Synthetic Assets and Derivatives

Synthetic assets and derivatives in the DEFI ecosystem allow users to gain exposure to various financial instruments and markets without actually owning the underlying assets. Platforms like Synthetix and dYdX enable users to create, trade, and manage synthetic assets and derivatives, expanding the range of financial products available in the DEFI space.

The Driving Forces Behind DEFI’s Popularity

There are several factors that have contributed to the growing popularity of DEFI. Some of the main drivers include:

  1. Financial Inclusion: It’s permissionless nature addresses the issue of financial exclusion, enabling unbanked and underbanked populations to access a wide array of financial services.
  2. Censorship Resistance: Decentralized platforms are less susceptible to censorship or interference by governments and regulatory bodies, ensuring greater financial freedom for users.
  3. User Empowerment: The platforms give users more control over their assets and financial decisions, as opposed to traditional financial institutions that often maintain strict control over customer funds.
  4. Programmability and Composability: The programmable nature of the platforms allows developers to create innovative financial products and services that cater to various user needs. Additionally, protocols can be easily integrated and combined, enabling the creation of complex financial systems built on top of one another.

What is DEFI’s Future?

As we’ve explored what is DEFI and why it started, it’s clear that it has the potential to revolutionize the financial sector, making it more inclusive, transparent, and efficient. Despite its rapid growth and increasing adoption, it’s is still in its early stages, and it will likely continue to evolve and mature in the coming years.

Challenges such as security, scalability, and regulation will need to be addressed for DEFI to reach its full potential. However, with continued innovation, collaboration, and adoption, DEFI could become an integral part of the global financial system, transforming the way we interact with money and financial services.
