Vitalik Buterin, co-founder of Ethereum, has issued a warning at the Devconnect conference about the potential threat posed by quantum computing to elliptic curve cryptography. He emphasized the urgency for Ethereum to transition to quantum-resistant cryptography within the next four years, ahead of the 2028 U.S. presidential election. Buterin also highlighted the need for future innovations to focus on Layer2 solutions, wallets, and privacy tools, rather than making changes to the core protocol layer. This strategic shift aims to enhance Ethereum's resilience and adaptability in the face of emerging technological challenges.
