Vitalik Buterin, Ethereum's founder, has announced his primary focus for 2025: Ethereum itself. In a Warpcast post, Buterin stated his dedication to advancing Ethereum's layer-1 long-term roadmap. This includes critical areas like single slot finality, the long-term virtual machine, enhanced security, and increased decentralization. Buterin also highlighted full-stack security and open-source projects as key areas of focus. While recognizing the importance of short-term scalability, P2P networking, block composition, and the application layer, Buterin indicated his direct involvement in these areas will be relatively less. This prioritization aligns with the recent Ethereum Foundation restructuring, allowing Buterin to dedicate more time to technical guidance and core Ethereum development. The Ethereum community anticipates significant progress in these fundamental areas throughout 2025. ```
