Explanation:
Understanding Decentralized Finance (DeFi)
Decentralized Finance, or DeFi, is a system that allows financial services to be conducted without the need for traditional intermediaries, like banks. Let’s evaluate each statement:
- A. Not everyone can use DeFi: This is correct. While DeFi platforms are accessible to anyone with an internet connection and a cryptocurrency wallet, some users may not be familiar or comfortable with the technology, limiting their ability to participate.
- B. Users must carry out real-name transactions on the DeFi platform: This is incorrect. One of the core principles of DeFi is the ability to remain pseudonymous; users are not required to provide real names to transact.
- C. After a transaction is carried out successfully on the DeFi platform, it can be cancelled: This is incorrect. Once a transaction is confirmed on the blockchain, it is permanent and cannot be cancelled. This immutability is a key feature of blockchain technology.
- D. A user can trade cryptocurrencies on DeFi platforms: This is correct. DeFi platforms offer various trading options for cryptocurrencies, allowing users to swap tokens directly without needing a centralized exchange.
In conclusion, the correct statements from the options are A and D.
