Ethereum Plans Early Completion of Post-Quantum and Post-AI Transition by December 2028
Justin Drake, a researcher at the Ethereum Foundation, aims to complete Ethereum’s shift to post-quantum and post-AI security by December 2028, advancing the timeline by one year from the foundation’s earlier target for quantum resistance.
At Devcon 8 held in Mumbai, Drake presented a faster schedule, stating, “We hope to finalize the entire post-quantum and post-AI transition by December 2028,” and noted that developers have two years to implement three more network upgrades.
The Ethereum Foundation’s roadmap released in September had previously marked December 2029 as the deadline for achieving quantum resistance across Ethereum’s execution engine, consensus mechanism, and data layers.
Drake’s recent comments suggest a more aggressive timetable; however, they do not officially replace the existing roadmap, which is set for review in January 2027.
In August, Drake revealed plans to launch leanVM technology ready for production use in 2027, followed by post-quantum deployments on Ethereum’s three layers throughout 2028.
This accelerated timeline has drawn attention from other blockchain developers. Specifically, in October, Starknet’s community supported further research on evolving into an independent post-quantum layer-1 network.
Eli Ben-Sasson, CEO of StarkWare, previously told Cointelegraph that Ethereum’s 2029 deadline was “too late,” cautioning that such timelines risk delays.
"Why": The Ethereum Foundation’s move to advance its post-quantum and post-AI transition deadline underscores the urgency to safeguard blockchain infrastructure against emerging quantum threats, highlighting the broader industry focus on maintaining security and future-proofing decentralized networks.
Why it matters
The Ethereum Foundation's decision to accelerate its quantum-resistance efforts reflects the critical importance of preparing blockchain networks for future technological threats, ensuring their resilience and security in a post-quantum computing era.
