DeFi Panel Discussion – Vienna Blockchain Week 2025

As part of Vienna Blockchain Week 2025, a high-level panel discussion focused on the future of Decentralized Finance (DeFi), exploring its potential, challenges, and the growing intersection between technology, regulation, and institutional adoption.

The panel was moderated by Kambis Kohansal Vajargah, Head of Startup Services and Deputy Head of Founder Services at the Austrian Federal Economic Chamber (WKÖ).
The distinguished speakers were:

• Alexander Lenz, General Partner at SMAPE Capital
• Ryan Zega, Head of Structured Finance at Aptos Labs
• Vinzenz Treytl, Senior Researcher at ABC Research
• Stefan Kobrc, Managing Partner at Stereum & Rocklogic

Together, they provided a deep and pragmatic look into the evolution of DeFi and its role in the global financial landscape.

DeFi is increasingly viewed as a foundational infrastructure layer of the modern financial system – not a replacement, but a technological evolution of it. The panelists discussed how DeFi already underpins a wide range of new financial services, from staking and lending to derivatives and insurance.

While the underlying blockchain technologies, particularly Ethereum, have matured considerably, mass adoption remains limited. Many users still find DeFi applications complex, and yields in major protocols are relatively low. Yet, the long-term benefits are clear: transparency, efficiency, and global accessibility without reliance on traditional intermediaries.

Risk and Technological Complexity

A recurring theme was the technical and security complexity of DeFi systems.
Smart contracts can contain vulnerabilities, and the interconnection of protocols often creates opaque risk chains. Stefan Kobrc noted that many projects are caught between innovation and over-engineering — everyone wants to add more layers, fees, and features, which can compromise transparency and usability.

Regulation and Licensing Challenges

One of the central discussions revolved around regulatory classification and licensing.
Ryan Zega pointed out the growing difficulty of distinguishing between pure software services and financial services. Whenever users earn interest or delegate assets, DeFi protocols may fall under traditional financial regulation.

The panel agreed that the future will likely bring regulated integration of DeFi structures, particularly for institutional players. A hybrid model is emerging — combining decentralized core technology with compliant interfaces that ensure investor protection, KYC, and AML standards.

Alexander Lenz argued that the industry will largely self-regulate before formal legislation catches up. Due to the fast pace of innovation, industry standards and third-party audits are becoming crucial interim solutions.

KYC, Identity, and Decentralization

The balance between decentralization and compliance remains one of the most pressing challenges.
The panel discussed that DeFi does not necessarily have to be anonymous or unregulated. Emerging technologies like Zero-Knowledge Proofs (ZKPs) and Decentralized Identifiers (DIDs) could make it possible to verify identity and compliance without compromising privacy.

According to Vinzenz Treytl, this step is critical for mainstream adoption: institutional investors and large-scale users will only participate if legal certainty and compliance can coexist with decentralization.

DeFi is engaged in an ongoing race for efficiency. Platforms compete on transaction costs, speed, and yield sustainability.
Ryan Zega noted that scalability is not purely a technical issue — it’s also economic and operational. The question is: who can deliver the same service cheaper, faster, and safer?

Stefan Kobrc highlighted that Layer-2 networks, modular architectures, and improved interoperability will play a decisive role in overcoming current limitations. However, he warned that scaling should not come at the expense of security — particularly in systems managing billions in locked value.

Education as the Key to Adoption

Toward the end of the discussion, the focus shifted to education and awareness.
Kambis Kohansal Vajargah stressed the urgent need to strengthen financial and technological literacy across society.

Vinzenz Treytl mentioned that several universities are integrating DeFi and blockchain into their business and economics curricula. Alexander Lenz added that understanding and trust are the foundation of adoption — users must know how DeFi works to benefit from it and avoid scams.

Stefan Kobrc emphasized the role of public–private partnerships in fostering this knowledge. Collaboration between chambers of commerce, academic institutions, and private companies could create the necessary framework for financial empowerment in the digital era.

Outlook: The DeFi Ecosystem in 2030

Looking ahead, the panelists envisioned a hybrid financial future, where DeFi and traditional finance coexist and reinforce each other.
Ryan Zega spoke of a world where decentralized and centralized finance merge, combining regulatory assurance with technological innovation.

Alexander Lenz pointed out that DeFi will not eliminate banks but transform them. Institutions will adopt DeFi to enhance efficiency, transparency, and customer access.

In essence, the future is hybrid — decentralized at its core, but with compliant and secure entry points for institutions and individuals alike.

Conclusion

The DeFi Panel at Vienna Blockchain Week 2025 demonstrated that decentralized finance has reached a new level of maturity.
The conversation made clear that technological progress alone is not enough — the future of DeFi will depend on trust, regulation, education, and collaboration.DeFi is not merely a financial trend. It represents the next stage in the evolution of global financial infrastructure — open, interconnected, and intelligent.
