Vitalik clarifies Ethereum’s transition from eWASM to RISC-V

During a fireside chat held at Pragma Taipei in April of 2025, Ethereum co-founder Vitalik Buterin shed light on the motivations driving the platform’s recent shift in direction. Buterin articulated how the evolution of Ethereum was rooted in a desire to address the challenges and limitations faced by the platform as it sought to scale and accommodate a growing user base.

One of the key factors influencing the decision to pivot was the need to enhance Ethereum’s scalability. Buterin emphasized that the previous framework was not equipped to handle the increasing demands placed on the platform, resulting in congestion and delays. By refocusing efforts on scalability, Ethereum aims to improve the user experience and create a more efficient system.

Another pivotal consideration behind the pivot was the recognition of the growing importance of sustainability and environmental impact. Buterin acknowledged that the energy-intensive nature of blockchain technology, particularly proof-of-work consensus mechanisms, was no longer tenable in a world increasingly concerned with climate change. As a result, Ethereum has made a deliberate shift towards more sustainable and eco-friendly solutions, such as proof-of-stake.

Additionally, Buterin highlighted the importance of interoperability in the blockchain space. By aligning with industry standards and fostering compatibility with other platforms and protocols, Ethereum seeks to create a more cohesive and interconnected ecosystem. This approach not only increases usability for developers and users but also enhances the overall value proposition of the platform.

Furthermore, Buterin underscored the significance of community feedback and engagement in shaping Ethereum’s evolution. By listening to the needs and preferences of its users, Ethereum is able to pivot and adapt in ways that best serve its community. This emphasis on inclusivity and responsiveness ensures that Ethereum remains relevant and responsive to the ever-changing landscape of blockchain technology.

In conclusion, Buterin’s insights at Pragma Taipei offer valuable perspective on the rationale behind Ethereum’s strategic pivot. By prioritizing scalability, sustainability, interoperability, and community engagement, Ethereum is positioning itself for continued growth and success in the evolving world of blockchain technology.
