Ethereum creates a team dedicated to post-quantum security

The quantum era is fast approaching. These computers capable of defeating current cryptographies are no longer fiction. Technological infrastructures, from banks to blockchain networks, could soon tremble. Bitcoin and Ethereum are no exceptions: their encryption schemes, which protect billions and transactions, will become vulnerable. In this context, Ethereum has decided to get ahead. 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 increasingly worry the crypto industry. In response, the Ethereum Foundation has set up a Post-Quantum Team, led by Thomas Coratger, supported by Emile, one of the minds behind leanVM, a cryptographic engine now central to the network’s strategy.

Researcher Justin Drake, a pillar of the foundation, summarized the situation clearly:

We are in 2026, deadlines are accelerating. It is time to fully switch to post-quantum.

This strategic shift is not just a publicity stunt. Two million-dollar prizes — the Poseidon Prize and the Proximity Prize — will reward researchers capable of strengthening the network’s cryptography. Multi-client devnets (Lighthouse, Prysm, Grandine) are already testing large-scale post-quantum protocols.

This initiative illustrates Ethereum’s desire to go beyond mere 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 start under the leadership of Antonio Sanso. They will focus on three main areas:

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

Drake also issued a rallying cry:

Believe in something. Believe in post-quantum security.

This approach is not isolated. The site pq.ethereum.org now centralizes all the advances, while a complete roadmap ensures a transition without fund losses or service interruptions.

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

Behind this technical shift, one 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 on X, he wrote:

To be able to claim “The Ethereum protocol, as it exists today, is cryptographically secure for one hundred years” is a goal we should achieve as soon as possible, and claim with pride.

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

The ambitions of Buterin follow the current movement: turning Ethereum into a trust anchor for the coming decades.

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

Facts and figures to remember about Ethereum and quantum security

• The Ethereum Post-Quantum (PQ) team is led by Thomas Coratger;
• Two $1 million prizes support cryptographic research;
• Multi-client devnets are already testing post-quantum compatibility;
• The transition aims for zero fund loss and zero network interruption;
• The ETH price currently trades around $2,953.

The race to quantum does not stop at the Ethereum foundation. Other blockchain players are also taking the lead. Recently, Coinbase set up an expert council dedicated to protecting networks against future quantum threats. The crypto ecosystem is preparing. 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.
