From Consensus to Execution, Ethereum Starts a Full System Trim

• Ethereum to simplify both consensus and execution layers in 2025
• Vitalik Buterin proposes RISC-V and “beam chain” to cut protocol complexity
• Protocol shift aims to improve resilience, decentralization, and validator access

Ethereum (ETH) developers are taking on a major simplification effort for the core protocol, targeting improved resilience and scalability. This push addresses concerns that the current network’s complexity creates long-term risks like high development overhead and a large attack surface, aiming for a leaner design closer to Bitcoin’s philosophy. 

At the core of this shift is the recognition that simplicity isn’t just about fewer lines of code; it’s about making the protocol more understandable, robust, and decentralized. 

Vitalik Buterin, Ethereum’s co-founder, is now pushing for a radical redesign that restructures both the consensus and execution layers, enabling a leaner and more sustainable future.
