Brief History of DeFi

The history of DeFi can be traced back to the early days of cryptocurrency and blockchain technology. While the concept of decentralised finance has gained significant traction in recent years, its foundations were laid by pioneering projects that explored the potential of blockchain for financial applications.

In 2009, the launch of Bitcoin introduced the world to the concept of a decentralised digital currency. Bitcoin revolutionised the financial landscape by enabling peer-to-peer transactions without the need for intermediaries. This marked the beginning of a new era in which individuals could transact directly with one another, bypassing traditional financial institutions.

The next major development came with the introduction of Ethereum in 2015. Ethereum introduced the concept of smart contracts, programmable contracts that automatically execute predefined actions when specific conditions are met. This innovation opened up new possibilities for creating decentralised applications (dApps) on the blockchain.

One of the earliest DeFi projects to gain attention was MakerDAO, launched on the Ethereum blockchain in 2017. MakerDAO introduced the concept of decentralised stablecoins, with Dai being the first stablecoin to gain significant traction. Stablecoins are cryptocurrencies designed to maintain a stable value, often pegged to a fiat currency, providing stability and mitigating the volatility commonly associated with cryptocurrencies.

In the same year, decentralised exchanges (DEXs) like EtherDelta emerged, allowing users to trade digital assets directly without the need for intermediaries. DEXs provided a decentralised alternative to centralised exchanges, offering increased security, privacy, and control over funds.

The year 2020 witnessed an explosion of DeFi projects and protocols. The introduction of liquidity mining and yield farming models brought increased attention and participation to the DeFi ecosystem. These models incentivised users to provide liquidity to decentralised exchanges and lending platforms, earning rewards in the form of additional tokens or fees.

Projects like Compound, Aave, and Synthetix gained prominence by offering decentralised lending and borrowing services, enabling users to earn interest on their assets or access loans without traditional credit checks. The composability of DeFi protocols allowed users to combine different platforms and strategies to maximise their returns.

Uniswap, a decentralised exchange protocol built on Ethereum, introduced the concept of automated market making (AMM), revolutionising token swaps. Uniswap's decentralised nature, coupled with its user-friendly interface, contributed to its widespread adoption and became a significant driver for the DeFi ecosystem's growth.

As DeFi gained momentum, the Total Value Locked (TVL) in DeFi protocols soared, reaching billions of dollars. This surge in activity attracted attention from both retail investors and institutional players, highlighting the potential and disruptive nature of decentralised finance.

2. What is DeFi?

DeFi, short for Decentralised Finance, is a term used to describe a financial system built on blockchain technology that operates in a decentralised and permissionless manner. Unlike traditional finance, which relies on centralised intermediaries such as banks, DeFi aims to create a financial ecosystem that is open, transparent, and accessible to anyone with an internet connection.

At its core, DeFi leverages the power of blockchain networks, particularly smart contracts, to enable the execution of financial transactions and the provision of financial services without relying on intermediaries. Smart contracts are self-executing agreements with predefined rules and conditions encoded on the blockchain. They automatically execute transactions and ensure the integrity and transparency of the system.

The fundamental principle of DeFi is decentralisation. By eliminating the need for intermediaries, DeFi seeks to democratise financial services, allowing individuals to have full control and ownership of their funds. It enables peer-to-peer transactions, where users can interact directly with each other, lending, borrowing, trading, and investing without the need for traditional financial institutions.
