Ethereum is strengthening its network security ahead of the quantum age, a technology that has the potential to break existing cryptographic systems and jeopardize digital transactions.
Recognizing this risk, the Ethereum Foundation (EF) has established a Post-Quantum (PQ) task force led by Thomas Coratger, with support from Emile, to develop cryptography and protocols that are resistant to quantum attacks.
As a practical measure, the EF will hold biweekly developer sessions focused on quantum-resistant transactions, user protection, and the development of more secure accounts through account abstraction techniques.
They are also experimenting with leanVM, a lightweight zero-proof virtual machine (zkVM), to more securely collect and verify transaction signatures.
The EF is also supporting this initiative with $2 million in funding: $1 million for the Poseidon Prize, strengthening Poseidon’s hash function, and $1 million for the Proximity Prize, driving post-quantum cryptographic innovation.
Additionally, a multi-client test network has been built and the developer team collaborates through weekly calls to ensure the compatibility and security of this new technology.
Ethereum’s move is in line with the crypto industry as a whole.
Coinbase recently established a quantum risk advisory board to assess the impact of quantum computers on Ethereum, Bitcoin, and other blockchains, with the first guidance paper expected to be published in early 2027.
With a combination of dedicated teams, funding, developer education, and technology testing, Ethereum is now positioning itself at the forefront of preparing for the quantum era, ensuring its network remains secure even as quantum technology becomes a reality.
