What is DeFi?

The term DeFi, or Decentralized Finance, refers to a set of financial applications built on blockchain technology. Unlike the traditional financial system, which is controlled by banks and financial institutions, DeFi platforms operate autonomously, using smart contracts. These applications allow users to conduct transactions, borrow and borrow, trade assets and more, all without intermediaries. DeFi growth has been exponential, with a significant increase in adoption and total blocked value (TVL) across multiple platforms.

How does DeFi work?

DeFi platforms work through smart contracts, which are self-executable codes stored on a blockchain. These contracts automate transactions and ensure that the rules of the agreement are complied with. For example, on a DeFi loan platform, a contract can allow a user to deposit cryptocurrencies as collateral and, in exchange, receive a loan in another cryptocurrency. Transactions are recorded on a public network, ensuring transparency and security.

Advantages and Disadvantages of DeFi

advantages

  • Global access: Anyone with an internet connection can access financial services.
  • Low fees: In many cases, transaction fees are lower than in traditional systems.
  • Transparency: All transactions are visible on the blockchain, which increases confidence.
  • Innovation: The DeFi space is constantly evolving, bringing new solutions and financial products.

Disadvantages

  • Security Risk: While blockchain are secure, smart contracts can have flaws.
  • Complexity: Using DeFi platforms can be complicated for beginners.
  • Volatility: The value of digital assets can be extremely volatile, which poses risks for users.

Impact of IA on DeFi

According to a recent report, AI agents already dominate about a fifth of the DeFi market, especially in predictable areas. However, when transactions become more complex, humans still outperform machines in performance. This raises questions about how AI can be used to improve efficiency and security in the DeFi ecosystem, but also highlights the importance of human judgment in financial decisions.

Events and Trends in DeFi

Money20/20 Asia, the global fintech event, announced an impressive programming with 250 speakers from 39 countries, reflecting the growing importance of DeFi and fintechs in the global financial scene.

Practical Examples of DeFi

The Loan Platforms

One of DeFi’s most popular applications are lending platforms such as Aave and Compound. In them, users can borrow their digital assets and earn interest, or take loans by providing collateral. For example, when depositing Ethereum, the user can receive DAI, a stablecoin, as a loan.

Exchange of Assets

Decentralized exchanges (DEX), such as Uniswap and SushiSwap, allow users to trade cryptocurrencies directly with each other, without intermediaries.This reduces fees and increases privacy, becoming an increasingly popular solution among investors.

FAQs

What is the difference between DeFi and CeFi?

DeFi (Decentralized Finance) operates without intermediaries, while CeFi (Centralized Finance) is managed by traditional financial institutions that control transactions.

How can I start using DeFi?

To start using DeFi, you need a cryptocurrency wallet and some knowledge about the available platforms.

Is DeFi Safe?

While DeFi offers security through blockchain, there are still risks, such as the vulnerabilities in smart contracts.

What are the rates involved in DeFi?

The rates on DeFi can vary depending on the platform and the transaction. Generally, the rates are lower than on traditional platforms, but can increase in periods of high demand.

What is TVL in DeFi?

TVL, or Total Value Locked, refers to the total value of assets that are being used in DeFi applications.
