Ethereum, the engine of blockchain innovation, faces a major challenge: its growing complexity. Vitalik Buterin, co-founder of the network, warns about protocol congestion, an excess of complexity that threatens Ethereum's efficiency and security. To address this, he proposes a radical solution: simplifying the code by removing superfluous elements. However, this approach raises questions: can Ethereum be lightened without compromising its core principles of decentralization and trust?
