Ethereum creates a team dedicated to post-quantum security

The quantum era is fast approaching. These computers capable of thwarting current cryptographies are no longer a fiction. Technology infrastructure, from banks to blockchain networks, could soon shake. Bitcoin and Ethereum are no exception: their encryption schemes, which protect billions and transactions, will become vulnerable. In this context, Ethereum has decided to get a head start. The foundation announces the formation of a team entirely dedicated to post-quantum security.

When crypto enters the post-quantum era

The threats of quantum computing are increasingly worrying the crypto industry. In response, the Ethereum Foundation established a Post-Quantum Teamled by Thomas Coratger, supported by Emile, one of the brains behind leanVM, a cryptographic engine now central to the network's strategy.

Researcher Justin Drake, pillar of the foundation, summed up the situation clearly:

We are in 2026, deadlines are accelerating. It’s time to go fully post-quantum.

This strategic shift is not just an announcement effect. Two million-dollar prizes — the Poseidon Prize and the Proximity Prize — will recognize researchers who can strengthen the network's cryptography. Multi-client devnets (Lighthouse, Prysm, Grandine) are already testing post-quantum protocols on a large scale.

This initiative illustrates Ethereum's desire to go beyond simple anticipation: it is now about building a blockchain infrastructure capable of resisting the future, before the future threatens it.

Ethereum wants to resist time and machines

Ethereum is no longer in the experimental phase: post-quantum engineering is underway. Bi-weekly development sessions will begin under the leadership of Antonio Sanso. They will focus on three major areas:

• the design of post-quantum transactions;
• the introduction of dedicated cryptographic precompiles;
• and signature aggregation resistant to future attacks.

Drake also launched a rallying cry:

Believe in something. Believe in post-quantum security.

This approach is not isolated. The pq.ethereum.org site now centralizes all progress, while a comprehensive roadmap guarantees a transition without loss of funds or interruption of service.

The approach marks a break with the philosophy of successive updates: Ethereum is entering a phase of industrialization of its security.

Behind this technical shift, a conviction dominates: to last a hundred years, a blockchain must think today about the threats of the next century.

Vitalik Buterin and the dream of an immortal blockchain

Behind this technical evolution lies a vision: that of Vitalik Buterin. For him, Ethereum must not only survive bugs or crises, but generations.

In a long post onhe wrote:

Being able to say “The Ethereum protocol, as it exists today, is cryptographically secure for a hundred years” is a goal that we should achieve as quickly as possible, and claim with pride.

His concept of the “walkaway test” has become a reference: Ethereum must remain functional even if its developers disappear. This requires rethinking the basic architecture – signatures, storage, economic models – to create a truly autonomous and sustainable protocol.

Buterin's ambitions are a continuation of the current movement: transforming Ethereum into a trusted block for decades to come.

This turning point is not only technological. It redefines the mission of the crypto-sphere: no longer chasing innovations, but building foundations that stand the test of time.

Facts and figures to remember about Ethereum and quantum security

• Ethereum's Post-Quantum (PQ) team is led by Thomas Coratger;
• Two $1M Prizes Support Crypto Research;
• Multi-client devnets are already testing post-quantum compatibility;
• The transition aims for zero loss of funds and zero network disruption;
• The price of ETH is currently trading around $2,953.

The race for quantum does not stop at the Ethereum foundation. Other blockchain players are also taking the lead. Recently, Coinbase established an expert council dedicated to protecting networks against future quantum threats. The crypto ecosystem is getting ready. Because in the battle between the power of machines and the robustness of protocols, caution is no longer an option: it is a survival strategy.
