Ethlabs proposed completing Ethereum's post-quantum upgrade in 2027, arguing that accelerating quantum threats require an earlier deadline. Ethlabs presented the initiative, called "pqai27", on the Ethereum Magicians forum. Ethlabs said AI is bringing quantum and cryptographic risks closer while giving Ethereum an opportunity to establish a durable role as a credible decentralized root of trust.
The Ethereum Foundation had previously set December 2029 as the target for full post-quantum readiness. Ethlabs noted that the U.S. government had advanced its quantum risk target from 2035 to 2030. Ethlabs also noted that Google now targets post-quantum readiness by 2029.
Ethlabs said the group also intends to achieve "post-AI" readiness by 2027. Ethlabs defined that goal as cryptography requiring minimal assumptions and clients protected against frontier models capable of discovering bugs at scale. Ethlabs said formal verification and Ethereum's diversity of clients would support those protections. Ethlabs cited AI systems solving hundreds of previously unsolved mathematics problems and discovering roughly 1,000 Linux vulnerabilities. Ethlabs argued that cryptographic security itself remains an unsolved mathematical problem. Ethlabs said the arrival of individual threats has become harder to predict and that current AI capabilities already accelerate all those threats.
Ethlabs outlined two standards for readiness in 2027. Under "pqai-ready", consensus would be post-quantum, users would have a post-quantum option for accounts, and the network would maintain scaled capacity. Under "pqai-scaled", the network would support full capacity with post-quantum transactions and data availability.
The proposal argued that a 2027 deadline will protect Ethereum's long-term role as a credible decentralized root of trust for the global economy. The proposal said resilience against AI-driven uncertainty will become Ethereum's next major distinguishing feature. The proposal predicted greater demand for security and uninterrupted operation as software attacks increase. The proposal argued that committing now would cost less than changing direction later, once work on the currently planned fork is well advanced.
Ethlabs said Ethereum already has a clear implementation path based on hash-function-based cryptography that requires minimal assumptions. Ethlabs cited years of research, a dedicated post-quantum team and established formal verification practices as supporting that path. Ethlabs said upcoming hard forks, including Hegotá, should be reviewed to reconsider changes outside the essential work for post-quantum and post-AI readiness. Ethlabs said the group will remove quick slots from Hegotá and devote resources to pqai27. Quick slots is a proposal to accelerate network block production. Ethlabs said a community survey had shown clear demand for quick slots and that abandoning the proposal was a difficult decision. Ethlabs said the group was prepared to defend the decision to people who had trusted Ethlabs to deliver quick slots.
Former Ethereum Foundation researchers founded Ethlabs. Ethlabs began operating earlier this year as a nonprofit focused on Ethereum research and development.
