Ethereum co-founder Vitalik Buterin has called on the Ethereum community to adopt a more open and bold mindset in developing the application layer, while maintaining the core attributes of Layer 1, such as censorship resistance, open-source, privacy, and security (CROPS). Buterin highlighted the potential impact of AI on applications like wallets and emphasized the need to rethink privacy architecture, DeFi structures, and the role of Layer 2 solutions. He encouraged developers to redesign the application layer ecosystem with a "start from scratch" approach.
