Ethereum's development trajectory is firmly focused on scalability and efficiency, with the live Fusaka upgrade and planned 2026 hard forks like Glamsterdam systematically enhancing data availability and validator performance. The Glamsterdam upgrade aims to scale the base layer with parallel execution and higher gas limits, targeting deployment around mid-2026. Following that, the Hegotá upgrade is scheduled for the second half of 2026, focusing on Verkle Trees for stateless clients and stronger censorship resistance. The roadmap also includes The Strawmap Vision through 2029, outlining seven hard forks targeting faster finality, quantum security, and native privacy features.
