Ethereum Outlines Roadmap for Lean Ethereum Transition by 2029

Key Facts

Ethereum has outlined a fork plan to transition to 'Lean Ethereum' by 2029, focusing on scalability and security enhancements. Crypto Briefing reported that the roadmap involves a sequence of approximately seven hard forks designed to rebuild the network's consensus, execution, and data layers while maintaining backward compatibility for existing applications.

The plan positions Lean Ethereum as the third major version of the protocol, emphasizing efficiency and post-quantum resistance. Vitalik Buterin has highlighted the threat of quantum computing as a driver for the transition, with the Glamsterdam fork scheduled next and the Hegotá fork expected in late 2026 or early 2027 as precursors to the final 2029 goal.
