The Ethereum Foundation announced the formation of a dedicated post-quantum (PQ) team and a $1 million Poseidon Prize on January 25, 2026, to accelerate Ethereum’s transition to quantum-resistant cryptography, ensuring zero downtime and zero loss of funds as quantum computing advances threaten current encryption.
Today marks an inflection in the Ethereum Foundation's long-term quantum strategy.

The PQ team, led by cryptographic engineer Thomas Coratger and supported by leanVM specialist Emile, will focus on hardening Ethereum against quantum attacks. The $1M prize targets cryptographers to secure the encryption algorithm powering leanVM, the EF’s post-quantum cornerstone. Multi-client PQ consensus devnets are already live, with calls made twice a week to address user-facing transitions like precompiles, account abstraction, and transaction aggregation.
Vitalik Buterin had previously emphasized urgency in a post made in December 2023, saying that Ethereum must achieve full quantum-resistance “as soon as possible” so the protocol’s cryptography can be trusted for a hundred years. The initiative follows Coinbase’s quantum advisory board formation and Project Eleven’s $120M valuation, indicating growing industry concern over quantum threats to elliptic curve cryptography.
The reaction to the news on X has been largely bullish, with many commenters praising Ethereum’s proactive nature. Vance Spence, co-founder of Framework Ventures, believes ETH will be the only quantum-secure asset if the status quo plays out. In an interesting exchange, his prediction was challenged by Vishall Kankani, a multicoin investor, who believes instead that a quantum computing breakthrough that breaks Bitcoin would shatter institutional trust in the entire crypto monetary system, not just one chain. According to him, especially since that trust is built on Bitcoin’s 15-year social consensus and credibility as a store of value, not technical superiority, it will make any systemic threat drag down all crypto rather than trigger a clean rotation to ETH.
This is wrong from a quantum perspective.
If Bitcoin breaks, institutional trust in all crypto breaks. It took ~15 years for institutions to accept BTC, and that trust is in the crypto monetary system—not in one chain’s tech stack.
A real quantum threat would be systemic. It… https://t.co/bGd0V4AreN

For effectiveness, the EF plans a comprehensive roadmap for a seamless PQ upgrade, minimizing disruption for users and developers. Current efforts include testing across clients to ensure consensus stability and exploring precompiles for efficient PQ signatures.
From a user perspective, the PQ initiative is a proactive safeguard, as it could eventually see quantum computers break ECDSA signatures, putting funds at risk if unaddressed. This means future-proofing wallets, funds, and dApps against quantum decryption risks, critical as Ethereum scales to handle trillions in value.
The zero-downtime/zero-loss ambition is ambitious and might be seen as a reach by some, but it is undeniably essential. Key amongst its usefulness is it prioritizes seamless transitions, and helps to avoid forced migrations or asset freezes experienced in past upgrades. Developers also get to gain tools like leanVM for secure PQ applications, while the monetary prize incentivizes open up innovation.
Ultimately, opening the initiative to devnets will undoubtedly invite broader cryptographic expertise, potentially speeding up progress beyond EF’s core team. However, the project is not without risks. PQ upgrades are complex, and rushed implementation could introduce vulnerabilities. If delayed, competitors with earlier PQ focus could gain an edge on Ethereum, but the real win for users is a network that remains trustworthy as quantum threats materialize around the ecosystem.
