Ethlabs proposed moving Ethereum's post-quantum upgrade forward to 2027, arguing that AI is accelerating quantum timelines. The group also wants the network to become "post-AI" by the same year, and it will withdraw its quick slots proposal from the Hegotá fork to focus on the effort.
Ethlabs proposed bringing forward Ethereum's post-quantum upgrade to 2027, arguing that accelerating quantum timelines makes earlier action necessary. In a post on the Ethereum Magicians forum, the group calls the plan "pqai27" and says AI is speeding up quantum and cryptographic risks.
Why Ethlabs wants to move now
Ethlabs noted that the U.S. government moved its quantum risk goal from 2035 to 2030 and that Google now aims to be post-quantum by 2029. The Ethereum Foundation previously set December 2029 for Ethereum's full post-quantum readiness.
The group went further than quantum risk. According to Ethlabs: "Being post-quantum is not enough; we intend on being post-AI too," it wrote. It defined post-AI as cryptography that rests on as few assumptions as possible, plus clients hardened against frontier models that find bugs at scale.
It also pointed to AI finding roughly 1,000 vulnerabilities in Linux and solving hundreds of open mathematics problems.
Two readiness levels for 2027
Ethlabs distinguished two levels of readiness for 2027. Under "pqai-ready," consensus is post-quantum and users have a post-quantum route for their accounts while the network continues at scaled capacity. Under "pqai-scaled," the network operates at full capacity with post-quantum transactions and data availability.
The proposal said Ethereum already has a clear technical path, built around hash-function-based cryptography with minimal assumptions, a dedicated post-quantum team and embedded formal verification practices.
Hegotá fork gets reassessed
To meet the 2027 target, Ethlabs said upcoming hard forks, including Hegotá, should be reassessed so that anything not on the critical path to post-quantum and post-AI readiness is reconsidered. The group stated it will withdraw quick slots, a proposal to make block production faster, from Hegotá and dedicate its resources to pqai27.
Ethlabs launched earlier this year as a nonprofit for Ethereum research and development, founded by former Ethereum Foundation researchers.
