TL;DR
- Ethlabs proposed making Ethereum post-quantum and plausibly post-AI ready in 2027, moving security work ahead of upgrades that are not essential to that goal.
- The group will withdraw Quick Slots from Hegotá and redirect resources toward post-quantum accounts, consensus, signature aggregation and data availability.
- Ethlabs argues accelerating AI capabilities increase uncertainty around cryptography and software security, although Ethereum core developers have not yet formally approved its proposed 2027 network roadmap.
Ethlabs has proposed moving Ethereum’s post-quantum and “plausibly post-AI” readiness target forward to 2027, arguing that accelerating artificial intelligence capabilities make long-range security timelines harder to predict. In its pqai27 proposal, the research group said the protocol should prioritize cryptographic resilience and client hardening over upgrades outside that critical path. The proposal would make security against emerging cryptographic threats a near-term priority for Ethereum, but core developers have not formally adopted the 2027 target.
Ethlabs Would Reshape Hegotá Around Post-Quantum Readiness
Under pqai27, Ethlabs distinguishes between being “pqai-ready” and “pqai-scaled.” The first milestone would make consensus post-quantum and give every user a post-quantum path for securing accounts, allowing Ethereum to keep operating at reduced capacity if classical cryptography unexpectedly fails. Full-scale readiness would later restore normal capacity for post-quantum transactions and blobs. The approach would accelerate the network’s existing post-quantum roadmap, which has already moved toward earlier targets than the previous 2029 timeline.
Reaching that goal would require reprioritizing Hegotá. Ethlabs said it will withdraw its Quick Slots proposal from the upgrade and redirect resources toward pqai27, while still pursuing faster slots in 2028. Frames and post-quantum account EIPs remain central because they could provide users with flexible authentication and migration paths, while developers still need to resolve how consensus itself becomes quantum-resistant. Signature aggregation through EIP-8288 and post-quantum data availability are key pieces of the full-capacity target, although the plan remains technically ambitious.
Ethlabs also pointed to external migration signals, noting that the U.S. government moved its quantum-risk planning goal from 2035 to 2030 and that Google now targets post-quantum readiness by 2029. The group argues that committing earlier is cheaper than pivoting later, when additional hardfork work could make a security-driven change more disruptive and expensive for core development teams. AI is the second reason Ethlabs wants to accelerate the schedule. The group argues that frontier models are solving previously open mathematics problems and finding software vulnerabilities at increasing scale, creating uncertainty around both cryptographic assumptions and client security. Ethlabs does not claim AI can currently break Ethereum’s cryptography, and it describes “post-AI” resilience as plausible rather than provable. Its proposed defense combines fewer cryptographic assumptions with stronger formal verification and client diversity, while Glamsterdam would continue as planned and work above the core protocol would remain unaffected.
