Hello, this is Jhon! A heated discussion in Seoul about the challenges and opportunities of DeFi.
Hello everyone! I'm Jhon, a Japanese blogger who follows the latest in blockchain technology. Today, I'll be bringing you the latest topics in DeFi (decentralized finance), which has been a hot topic on X (formerly Twitter) and other platforms. I'll explain it in an easy-to-understand way, starting with an event held in Seoul.
DeFi is a technology that revolutionizes traditional finance using blockchain, and recent events have seen lively discussions about its challenges and future opportunities. Why is this important now? As of 2025, with the cryptocurrency market booming, the spread of DeFi has the potential to transform more familiar financial services. Even if you're a beginner, let's learn together from here. If you're new to DeFi, we recommend starting by choosing a cryptocurrency exchange. Here's a simple comparison of the major services:How to Choose and Compare Cryptocurrency Exchanges for Beginners.
What is DeFi? Let's review the basics
DeFi, or Decentralized Finance, is a system that uses blockchain technology to provide financial services without the intervention of central institutions like banks. Lending, borrowing, and transactions are realized through smart contracts (automated programs). DeFi has grown rapidly over the past few years, and during its boom around 2021, total assets under custody reached several trillion yen. However, beginners may find it difficult. This part is simple. The idea is to easily lend cryptocurrency through an app and earn interest.
Hack Seasons Opportunity Mixer Background
This topic originated at the Hack Seasons Opportunity Mixer, held in Seoul at the end of September 2025. Industry experts gathered to discuss the challenges and opportunities of DeFi. According to organizers, the mixer is known as a networking forum for Web3 (decentralized web) innovators. While the integration of AI and Web3 has been a hot topic at past similar events since around 2024, the Seoul edition attracted attention with a panel dedicated to DeFi.
Key challenges facing DeFi discussed at the event
At the event, several challenges hindering the adoption of DeFi were cited, including a lack of developers and a complex user experience (UX). According to a report published on October 9, 2025, industry leaders stated that "improving DeFi UX will prevent mass adoption." Let's take a closer look.
- Security vulnerabilities: There is a high risk of hacking, and in the past, the Ronin Network attack in 2022 resulted in losses of tens of billions of yen.
- Regulatory uncertainty: As legal regulations become more prevalent in each country, the question of how DeFi projects can maintain compliance is a major issue.
- Scalability issues: Blockchains can be slow and have high transaction costs.
These challenges reflect the past growth of DeFi, and show how early excitement has hit a real roadblock.
DeFi Opportunities and Latest Trends
However, there were also many positive opportunities discussed at the event. A panel discussion on October 9, 2025, pointed out that infrastructure improvements and Layer 2 (blockchain extension layer) solutions will drive the next cycle of DeFi. Currently, tokenization of RWA (Real World Assets) is progressing, and there is active activity to make real estate and bonds tradable on the blockchain. For example, industry leaders emphasized that "simplified infrastructure will enable mass adoption."
Learning from real-world examples of DeFi
For practical examples, let's look at the projects mentioned at the event. Tools like MetaMask (a popular cryptocurrency wallet) serve as an entry point for DeFi. As of 2025, the trend is toward strengthening cross-chain (interconnection between different blockchains) security, and these technologies are making DeFi safer. Beginners are encouraged to start with a small amount.
Risks and Cautions: Safety First
DeFi offers many attractive opportunities, but it also carries risks. Since this is an investment-related discussion, please note: this is not investment advice. Due to the high market volatility and the potential for losses, you make your decisions at your own risk. In particular, be sure to take security measures. While it was discussed at the event that increased participation by institutional investors could help reduce risks, this is still in its infancy.
Outlook: What DeFi Will Bring
Having overcome past challenges, infrastructure is currently being strengthened. It is anticipated that integration with AI will further streamline DeFi, potentially making it a common financial service by around 2026. Event experts recommend community-driven growth as a sustainable adoption strategy. Why not join the trend?
