Recently, the Ethereum community has seen a surge in discussions regarding the Cancun upgrade. The most significant changes brought by this upgrade are the substantial decrease in transaction fees and the notable increase in processing speed. This improvement can be likened to a congested highway suddenly becoming clear, providing a smoother user experience for Decentralized Finance (DeFi) applications.

With the reduction of transaction costs and the increase in speed, various applications in the DeFi ecosystem, such as lending and trading platforms, will benefit greatly. This not only enhances the satisfaction of existing users but also hopes to lower the barriers to entry, attracting more new users to join the world of Decentralized Finance.

These seemingly minor technological improvements may actually contain significant changes in the future financial landscape. With the continuous advancement of blockchain technology, we might be witnessing the birth of a more open, efficient, and inclusive financial system. Although we are still in the early stages, these accumulated changes could lead to revolutionary developments in the future, reshaping our perception and use of financial services.
