The Ethereum Foundation has officially moved post-quantum (PQ) security from long-term research into active protocol engineering, making quantum resistance a top strategic priority for Ethereum’s 2026 roadmap.
After several years of theoretical groundwork, the foundation is now accelerating concrete implementations aimed at protecting wallets, signatures, and consensus mechanisms before quantum computing reaches a disruptive threshold.
Dedicated Post-Quantum Team Takes the Lead
To drive the transition, the Ethereum Foundation has formed a specialized Post-Quantum team led by Thomas Coratger. He is supported by cryptographer Emile, a key contributor behind leanVM, which underpins much of Ethereum’s emerging PQ cryptographic architecture.
Today marks an inflection in the Ethereum Foundation's long-term quantum strategy.

This team is responsible for coordinating research, client development, and ecosystem-wide upgrades as Ethereum moves toward what researchers describe as a “full PQ” future.
From Theory to Network-Level Implementation
EF researcher Justin Drake confirmed that faster-than-expected quantum timelines have forced a shift from abstract modeling to hands-on engineering. Several initiatives are already underway:
- Post-Quantum All Core Devs calls will begin in February 2026, running bi-weekly to address PQ transactions, wallet safety, account abstraction, and signature aggregation.
- A multi-client Post-Quantum Consensus Testnet is now live, allowing developers to stress-test quantum-resistant designs under real network conditions.
- The foundation has launched $2 million in cryptography bounties:
- The Poseidon Prize ($1M) focuses on strengthening the Poseidon hash function.
- The Proximity Prize ($1M) targets broader post-quantum research and practical implementations.
Rather than treating PQ security as an optional upgrade, Ethereum is embedding it directly into core protocol discussions.
Security Becomes the Center of the 2026 Roadmap
This move is part of a wider security-first pivot across Ethereum’s scaling stack. The foundation has set strict 128-bit provable security targets for zkEVM teams, to be met by the end of 2026. Internally, security is being framed as the primary bottleneck for long-term scaling, rather than throughput or cost.
To align developers and institutions, the Ethereum Foundation will host:
- A Post-Quantum Day in late March 2026, ahead of EthCC
- A major post-quantum security summit in October 2026, focused on enterprise adoption and ecosystem readiness
Preparing Before the Threat Becomes Real
Post-quantum research at the Ethereum Foundation began as early as 2019, but 2026 marks the first time those efforts have translated into concrete protocol pathways, testnets, and economic incentives.
The objective is clear: harden Ethereum’s cryptographic foundations before quantum hardware becomes powerful enough to threaten existing signature schemes, rather than reacting after vulnerabilities emerge.
In effect, Ethereum is treating quantum resistance not as a future risk, but as a present engineering problem.
