Vitalik Buterin emphasized the importance of simplicity in Bitcoin and suggested bringing those benefits to Ethereum.
Bitcoin's elegance lies in its simple core protocol, making it accessible and secure for hobbyist developers and enhancing decentralization.
On the other hand, Ethereum has grown in complexity due to smart contracts, staking, Layer-2s, and DeFi applications, making it harder to understand and scale securely.
Buterin proposes not to remove Ethereum's capabilities but to simplify the core protocol for easier verification and resistance to systemic risks, aiming for a powerful yet user-verifiable protocol.
