Ethereum co‑founder Vitalik Buterin announced a sweeping upgrade that will rebuild almost every core component of the network. The announcement marks the most extensive overhaul since the Merge, signaling a long‑term shift in the protocol’s architecture.
The plan covers consensus, execution, and infrastructure layers, aiming to replace legacy code with new, modular components. By redesigning these foundations, the team hopes to improve scalability, reduce complexity, and open the door to future innovations.
A key focus of the upgrade is quantum safety. As quantum computing threatens current cryptographic schemes, the new design will incorporate quantum‑resistant algorithms. Privacy enhancements, such as zero‑knowledge proofs, will also be integrated to give users stronger control over their data.
The roadmap spans three to four years, with phased milestones that will allow the community to test and validate each component before full deployment. The timeline is tentative and may shift as technical challenges and community feedback shape the process.
At this stage, the upgrade remains in the design phase, with limited public details. Developers are encouraged to contribute to discussions, and the Ethereum Foundation will release more concrete specifications as the project progresses. Stakeholders should monitor official channels for updates.
