Ethereum co-founder Vitalik Buterin has emphasized the importance of protocol stability at the 2025 Devconnect conference. He believes that over time, Ethereum’s core should become more stable and secure, shifting focus to Layer 2 solutions for innovation. This approach is expected to bolster investor confidence in ETH, leading to increased adoption of Layer 2 solutions. The move also addresses potential threats from quantum computing by requiring a transition to quantum-resistant cryptography. While Buterin acknowledges the need for innovation in areas like wallets and privacy tools, he envisions a future where Ethereum gradually ossifies its protocol, reducing frequent changes.
