The announcement was highlighted by Ethereum researcher Justin Drake, who confirmed that Thomas Coratger, a cryptographic engineer, will lead the new team, supported by experts experienced in post-quantum cryptographic design. The project signals a concerted effort to safeguard Ethereum’s protocol against concerns that powerful quantum computers could eventually compromise the cryptographic algorithms that protect digital signatures and private keys.
Why Quantum Security Matters
As blockchain systems rely heavily on cryptographic primitives, like elliptic-curve signatures, quantum computers capable of running powerful algorithms such as Shor’s algorithm could, in theory, break these protections if sufficient computing power is ever achieved. Although such quantum machines do not yet exist at the scale necessary to pose an immediate risk, the transition from theory to practical threat could happen before the community is fully prepared. Cryptographers therefore refer to the urgency of post-quantum upgrades long before ‘breakeven’ is reached.
To move beyond speculation and into active defense, the Foundation’s new team will explore practical implementations of post-quantum cryptographic solutions tailored for Ethereum, including hashbased signatures and other quantumresistant schemes that are expected to withstand future quantum attacks.
How the Initiative Is Structured
The $2 million funding is being applied in a dual approach meant to accelerate both research and real-world engineering outcomes:
A portion of the funding, $1 million, is dedicated to strengthening specific cryptographic tools such as the Poseidon hash function, which plays a role in zero-knowledge proof systems and other cryptographic primitives used on Ethereum. The remaining $1 million supports broader developments in post-quantum cryptography through collaborative prize programs that encourage innovation and attract contributions from global security researchers.
The formation of the team also underscores a broader shift in priorities: quantum resistance is now treated as an implementable engineering challenge, not just a theoretical concern to be studied in academic papers. Bi-weekly developer sessions are scheduled to begin, bringing together core developers to work on transactionlevel protections and advanced signature schemes, as well as account abstraction strategies designed with quantum threats in mind.
From Research to Multi-Client Testing
The Post-Quantum team isn’t operating in isolation. Multi-client developer test networks focusing on quantumresistant consensus and cryptographic tools are already operational, enabling engineers from multiple Ethereum client formations to experiment and validate post-quantum features across different implementations.
Developer gatherings and planned workshops, including multi-day expert events and dedicated sessions ahead of major ecosystem conferences, aim to bring together academic cryptographers, protocol engineers, and industry stakeholders to cooperate on advancing quantum-secure standards for the entire ecosystem.
Industry Reactions and Timeline Debates
The initiative has sparked discussion among blockchain developers and researchers about when quantum threats might materialize. Some observers argue that quantum computing capabilities remain decades away, while others caution that preparation must happen long before practical attacks are possible, given the time required for secure rollout of post-quantum protocols across live networks.
Ethereum’s proactive stance, supported by structured funding, developer coordination, and dedicated cryptographic strategy, positions it as one of the first major blockchain ecosystems to publicly commit significant engineering resources toward post-quantum resilience.
What Comes Next
As the Ethereum Foundation’s quantum security program moves into full gear, the focus will shift from experimental research to protocollevel integration, practical tooling, and ecosystem readiness. The ongoing work aims to ensure that Ethereum remains secure in a future where quantum computing advances from theoretical capability to practical reality.
This multi-front strategy, from incentivized cryptographic development to real-world implementation scenarios, reflects a broader understanding in the blockchain community that quantum resistance is not optional but a necessary evolution for long-term network integrity and user protection.
Jessica Jones is not a person. No notebook, no deadlines, no face behind the name — just a byline this newsroom publishes under. Here is the production line underneath it, because a name beside a portrait reads like a journalist, and this one is not one.
The models. Writing: gpt-5.6-luna. Out on the live web: gpt-5.6-luna and gpt-5.6-terra. Pictures: gpt-image-1. Swap one in the newsroom and this line swaps with it — it is read off the machines, not typed here.
How a story is made
- Research. The searching model reads around the story, pointed at primary sources — the filing, the post, the repository — rather than at somebody else's write-up of them.
- Writing. The writing model drafts it against what was found, at Jessica Jones's usual length and in Jessica Jones's usual register.
- The loop. A reviewer reads the draft and sends it back with notes. Then reads it again. A piece can go round several times before it leaves the building.
- Enrichment. A quotation has to appear word for word on the page it is taken from. A chart may only use figures that appear in the source it cites. Whatever fails is dropped, and the reason is kept.
- Fact check. A last pass hunts for claims the article makes and its sources do not.
- A human stop. Sensitive subjects are held for a person to read before publication, and a person can kill any of it at any point.
If that sounds less like a newsroom and more like a factory: quite. It is called Press Factory.
