Ethereum Prioritizes Post-Quantum Readiness
Ethereum developers are deciding whether to make post-quantum readiness a collective focus and how quickly to deliver it.
It's Thursday, November 12, 2026.
Ethereum developers elevate the urgency of post-quantum readiness. Ethlabs proposes PQAI readiness by 2027, and Privacy Pools plans to support Aztec Network.

Ethlabs Proposes PQAI 2027 Readiness
Ethlabs, the independent Ethereum R&D Lab, introduced pqai27, its proposal to bring Ethereum to post-quantum readiness and post-AI security by 2027. Ethlabs argues that AI advances could accelerate cryptographic and software-security risks and calls for protocol developers to prioritize cryptography built on fewer assumptions and stronger client hardening. Ethlabs withdrew its Quick Slots proposal from the Hegotá upgrade and is dedicating its resources to pqai27.
Ethlabs urged core developers to rethink Hegotá’s scope. PQAI-ready means consensus uses post-quantum cryptography and users have a post-quantum path for their accounts, while Ethereum can continue operating at reduced capacity if current cryptography breaks. The long-term goal, termed pqai-scaled, is for Ethereum to run at full capacity with post-quantum transactions and blobs.
Ethereum Developers Elevate PQ Urgency
During today's All Core Devs Call, Ben Edgington presented a scale for determining the urgency of becoming post-quantum ready. The scale shows five escalating levels of cryptographic risk, from Level 1, where an imminent break requires an emergency full PQ focus, to Level 5, where a break is a decade away. Ethereum developers said the network is currently at Level 2–3. The Ethereum Foundation has set a goal of post-quantum resistance by 2028.
Ethereum developers are deciding whether to make pqai a collective focus. They are reopening the scope of the Hegotá upgrade, with Ethlabs already dropping Quick Slots. Hegotá headliner FOCIL is also under consideration for removal. Ethereum researcher Toni Wahrstätter says PQ has become Ethereum’s biggest focus, adding that prioritizing PQ could mean removing FOCIL from Hegotá.
The key decision is how quickly to deliver the post-quantum upgrade. Developers could work on pqai alongside other priorities or make it their top priority.
Privacy Pools To Support Aztec
Privacy Pools plans to deploy on Aztec, allowing assets shielded on Ethereum mainnet to bridge privately into the privacy-focused L2 network. Privacy Pools already supports private transfers, swaps, and yield within its own pool. It screens pool deposits using an Association Set Provider. The Aztec deployment aims to let users withdraw private assets from Privacy Pools into lending, trading, and payment apps on Aztec Network without exposing their balances, counterparties, or activity. The integration would break the link from a user deposit on Ethereum to a withdraw on Aztec.
