Ethlabs proposed advancing Ethereum's post-quantum upgrade, called pqai27, to 2027, posting the proposal on the Ethereum Magicians forum. Ethlabs said it will withdraw quick slots from the Hegotá hard fork and dedicate resources to pqai27.
Why it matters
Ethlabs said AI is accelerating quantum and cryptographic risk timelines, making it much harder to predict when threats will arrive. The proposal comes as the U.S. government moved its quantum risk goal from 2035 to 2030 and Google aims to be post-quantum by 2029.
Ethlabs defined pqai-ready as consensus being post-quantum with a post-quantum account route while the network continues at scaled capacity, and pqai-scaled as full capacity with post-quantum transactions and data availability. The proposal does not yet state whether the 2027 timeline has been accepted by the broader network.
The players
Ethlabs
A nonprofit organization founded by former Ethereum Foundation researchers that launched earlier this year to conduct Ethereum research and development.
Ethereum Foundation
The organization that supports the development of the Ethereum blockchain and previously set December 2029 as the target for full post-quantum readiness.
The details
Ethlabs, a nonprofit founded by former Ethereum Foundation researchers and launched earlier this year, said Ethereum already has a dedicated post-quantum team. The group argued that a pivot later, once the currently planned fork ships, would be far more costly than acting now.
Timeline
December 2029: Ethereum Foundation's prior target for full post-quantum readiness.
2027: Proposed target for the pqai27 upgrade.
2030: U.S. government's revised quantum risk goal, moved up from 2035.
The Tech Race
The proposal places Ethereum ahead of the U.S. government's revised 2030 quantum risk goal and Google's 2029 post-quantum target. It signals that blockchain networks are competing with major technology companies on the pace of cryptographic migration.
Users of Ethereum would eventually need to adopt post-quantum account routes to keep their transactions secure as the network migrates. The proposal's 2027 timeline would bring that migration earlier than the previously planned December 2029 readiness date.
The takeaway
Quantum threats are arriving on a timeline that is harder to predict, and blockchain developers are being asked to plan migrations sooner than previously expected. Ethereum users and developers should watch whether the community adopts the 2027 target.
