Ethereum Targets Quantum-Resistant Upgrade by 2029
The Ethereum Foundation has announced its plan to develop a fully quantum-resistant Ethereum layer 1 by December 2029. The goal covers all three major parts of Ethereum's base layer: execution, consensus, and data.
The foundation is taking proactive steps to prepare for the possibility that sufficiently powerful quantum computers could appear as early as 2030. However, it seems more likely that such a breakthrough will occur further into the future.
'Q-day cannot be scheduled, so we have assigned ourselves a self-imposed deadline,' said the Protocol Cluster.
The roadmap includes post-quantum signature schemes and changes across Ethereum's transaction, consensus, and data-availability systems. This comes as Ethereum developers begin determining the scope of Hegotá, the upgrade expected to follow Glamsterdam.
