In the current financial landscape, the Decentralized Finance (DeFi) born from blockchain technology is triggering a silent revolution. Compared to the TradFi system, DeFi can offer exceptionally attractive Annual Percentage Rates, often reaching double digits. The root of this phenomenon lies in the DeFi model's clever circumvention of the layered intermediary processes in the traditional financial system, significantly dropping transaction costs while innovating a more direct and efficient credit matching mechanism.

For visionary investors, participating in the DeFi ecosystem is not merely a speculative act, but a well-thought-out strategy. This strategy essentially involves arbitraging the institutional differences between the traditional financial system and emerging digital finance. This 'institutional arbitrage' requires investors to think outside the traditional frameworks and be bold enough to explore the potential opportunities in emerging markets.

However, to truly grasp the opportunities in this emerging field, investors need to have a comprehensive understanding of Blockchain technology, cryptoeconomics, and the operating mechanisms of decentralized systems. At the same time, they should also be aware of the potential risks involved, including smart contract vulnerabilities, market volatility, and other factors.

Overall, on-chain finance is reshaping the way financial services are provided, opening up a whole new avenue for investors to increase their wealth. However, this path is not smooth; it requires investors to possess keen insight, solid knowledge reserves, and prudent risk management skills. In this rapidly evolving field, only by continuously learning and keeping up with the times can one capture the real opportunities at the intersection of the old and new financial systems.
