(DeFi) is a financial system based on blockchain technology that automatically executes various financial services through smart contracts without relying on traditional financial institutions. The rise of DeFi has brought new possibilities to the financial world and is gradually subverting the traditional financial system.
1. Definition and characteristics of DeFi
Decentralization: DeFi achieves decentralized operations through blockchain and smart contract technology, eliminating dependence on intermediaries. All transactions and operations are recorded on a public blockchain, which is transparent and cannot be tampered with.
Openness: DeFi platforms are open to everyone, without cumbersome identity verification and high fees. Anyone can participate with just a digital wallet and an internet connection.
Borderless: DeFi breaks geographical restrictions. Users can conduct financial transactions and services on a global scale and participate in the decentralized financial ecosystem anytime and anywhere.
2. Development history of DeFi finance
The development of DeFi finance did not happen overnight but has gone through a series of important milestones. In the early days, the birth of Bitcoin marked the initial application of blockchain technology, and people began to realize its potential.
Subsequently, Ethereum introduced smart contracts, making cryptocurrencies programmable, laying the foundation for the development of DeFi. However, DeFi really began to receive widespread attention around 2020, especially with the rise of decentralized exchanges (such as Uniswap) and lending protocols (such as Compound and Aave), the DeFi ecosystem has expanded rapidly. This year, the total market value of DeFi protocols has increased significantly, attracting a large number of users and funds, and the era of financial transactions without middlemen has officially begun.
3. Core functions of DeFi
Lending services: DeFi platforms provide peer-to-peer lending services, where users can directly lend or borrow assets through smart contracts without the approval and intermediary fees of traditional banks. Common DeFi lending platforms include Aave and Compound.
Decentralized Exchange (DEX): Decentralized exchanges in DeFi allow users to trade assets directly on the blockchain, avoiding the security risks and high fees of centralized exchanges.
Stablecoins: In response to the volatility of the cryptocurrency market, DeFi platforms have launched stablecoins pegged to fiat currencies, such as USDT and DAI, providing a stable means of storing value.
Yield farming and liquidity mining : Users can get rewards by providing liquidity, which is called yield farming or liquidity mining. While providing liquidity, users can also get additional token rewards, increasing the income of assets.
4. Main applications of DeFi finance
DeFi finance has a wide range of uses. You can borrow and lend through the DeFi platform, using digital assets as collateral for lending without going through the cumbersome process of traditional banks. In addition, decentralized exchanges allow you to trade cryptocurrencies directly on the blockchain, avoiding the risks that may exist in centralized exchanges.
DeFi savings services offer higher interest returns than traditional banks, and you can deposit funds into smart contracts to earn returns. At the same time, DeFi payment services are more flexible and secure, and you can use tokens for instant payments and transfers. Finally, you can also purchase various digital assets on the DeFi platform for investment to achieve diversified asset allocation.
5. How DeFi subverts Traditional Finance
Efficient and low-cost: DeFi automatically executes transactions and operations through smart contracts, reducing dependence on intermediaries and reducing transaction costs. Compared with the cumbersome procedures and high fees of traditional financial institutions, DeFi is more efficient and economical.
Transparency and security: All DeFi operations are recorded on the blockchain, which is open and transparent and can be viewed and verified by anyone. This transparency improves the security of the system and reduces the possibility of fraud and corruption.
Inclusive Finance: DeFi is open to everyone, without cumbersome identity verification and high fees, providing new opportunities for people who cannot access traditional financial services. Anyone can participate in the global financial market with just a digital wallet.
Innovation and diversification: DeFi platforms continue to launch new financial products and services, such as decentralized insurance and derivatives trading, which enrich the types of financial products and meet the needs of different users.

6. Conclusion
As an innovative financial system, DeFi is gradually subverting the traditional financial system through its decentralization, openness, and borderlessness. Although DeFi still faces challenges in technology, security, and regulation, its advantages of efficiency, transparency, and inclusiveness make it likely to become one of the mainstream financial service models in the future. With the advancement of technology and the improvement of user acceptance, DeFi will continue to promote the transformation and development of the financial industry.
