DeFi vs CeFi are two models of financial systems. DeFi operates on blockchain technology, allowing users to engage in financial transactions without intermediaries like banks. In contrast, CeFi relies on centralized institutions to manage assets and transactions, providing a more traditional, regulated approach. DeFi offers transparency, greater privacy, and accessibility, while CeFi provides more user-friendly interfaces, higher liquidity, and regulated environments. Both systems cater to different user needs and preferences in the financial ecosystem.
