The quantum threat may still be years away, but Ethereum’s developers have no intention of letting it affect the digital platform. A dedicated team within the Ethereum Foundation has stepped up efforts to shield the world’s second-largest blockchain from the looming danger of quantum computing, launching a public resource hub and a live progress dashboard this week.
The resource hub serves as a one-stop library for developers and researchers, housing the full quantum-safety roadmap, technical specifications, research papers, open code repositories, and a plain-language FAQ written by the Post-Quantum team itself. It also features a six-part interview series for those looking to understand the threat beyond the technical jargon. The progress dashboard gives anyone—like a developer or curious observer—a real-time view of how far along each layer of Ethereum’s quantum-proofing work actually is.
The newly formed Post-Quantum team set a 2029 target to embed quantum-resistant solutions directly into Ethereum’s core system. Although the quantum attack is not imminent, the team stressed that upgrading a global decentralized network is not something that can be done overnight. It takes years of planning, testing, and coordination across hundreds of independent teams worldwide.
Justin Drake, a researcher at the Ethereum Foundation, had signaled the shift back in January, declaring post-quantum security a top strategic priority. “Timelines are accelerating,” he wrote. “Time to go full PQ.”

Building the Quantum Shield
To defend against future attacks, the team is using a cryptographic method that lets the network verify transactions without exposing any sensitive data. This approach keeps the network fast and lean, avoiding the performance slowdowns that heavier security methods typically bring.
The Foundation has put a lot of money behind the effort—a $1 million Poseidon Prize to strengthen a key security component, plus a separate $1 million research grant for broader quantum-safe cryptography work. More than ten developer teams are already building and testing solutions, with projects like Lighthouse and Grandine already live on test networks.
Why Ethereum Is Not Panicking
All these developments are very reassuring, especially as Ethereum’s exposure to quantum risk is around 0.1% of its network, far smaller than Bitcoin’s estimated 5% linked to older, mostly abandoned wallets. The threat is real but manageable.
But the bigger challenge is not designing the security itself but moving hundreds of millions of user accounts to the new system without any downtime or losses. That is the challenging part, and it is exactly why the work is starting early.
