Vitalik Buterin: Ethereum's Next Rebuild Will Rival the Merge, Take 3-4 Years

Ethereum co-founder Vitalik Buterin has stated that the next major rebuild of the Ethereum network will rival the Merge in significance and take 3-4 years to complete. He emphasized that quantum safety has "shifted up a LOT in priority" in recent planning.

The upcoming Hegota hard fork, slated for later this year, is expected to be Ethereum's last "pre-Lean" hard fork. Buterin highlighted that this upgrade will focus on improving the network's resistance to potential quantum computing threats, a critical step for long-term security.

For everyday users, this means continued evolution of Ethereum's infrastructure, potentially leading to better security and scalability. However, such a long development timeline suggests that major improvements may not be visible for several years, though incremental updates will likely continue in the meantime.

This announcement comes as Ethereum continues to refine its roadmap, with the Lean rebuild representing a fundamental shift in how the network operates. Users and developers should watch for updates on quantum-resistant cryptography and the progress of the Lean rebuild, as these will shape the future of Ethereum's security and functionality.
