Vitalik Buterin Calls for Ethereum to Build Full Quantum Resistance ‘As Soon As Possible’ – Why It Can’t Wait
Why Quantum Computing is a Growing Threat to Blockchain
Quantum computers are getting closer to reality. They could break the encryption that protects most cryptocurrencies today. Ethereum co-founder Vitalik Buterin knows this. He says the blockchain must gain full quantum resistance right away. No more waiting.
Recent news about Google’s Willow chip has raised alarms. This powerful quantum processor shows progress is fast. Experts worry a full-scale quantum machine could crack codes like ECDSA, used in Ethereum wallets. That means hackers could steal funds from any address with a known public key.
Vitalik’s Urgent Message on X
On January 12, Vitalik posted a detailed thread on X (formerly Twitter). He warned against delaying quantum upgrades for short-term gains. “We should resist the trap of saying ‘let’s delay quantum-resistance until the last possible moment in the name of ekeing out more efficiencies for a while longer,” he wrote. “Individual users have that right, but the protocol should not.”
“Ethereum holders should be able to say the protocol is cryptographically secure for the next 100 years ‘as soon as possible’ and ‘as a point of pride.'”

What Does Quantum Resistance Mean for Ethereum?
Today’s blockchains use math that’s easy for regular computers but hard for quantum ones. Quantum computers use qubits. They solve problems super fast with tricks like superposition.
- Current weakness: Signatures like ECDSA and EdDSA can be broken by Shor’s algorithm.
- Solution: Switch to post-quantum cryptography. Options include lattice-based schemes (like Kyber) or hash-based signatures (like SPHINCS+).
Ethereum isn’t alone. Bitcoin faces the same risk. But acting now gives time to migrate wallets and smart contracts safely.
Beyond Quantum: Vitalik’s Full Roadmap for Ethereum Maturity
Vitalik didn’t stop at quantum threats. He listed key goals to make Ethereum unbreakable:
- Scale to thousands of TPS: Handle more transactions per second without high fees.
- Full account abstraction: Let users customize wallets like smart contracts. No more seed phrases only.
- DoS resistance: Block denial-of-service attacks that spam the network.
- Censorship-resistant block building: Ensure no one can stop transactions unfairly.
“Every year, we should tick off at least one of these boxes, and ideally multiple,” he said. Ethereum as a “hammer” – buy it once, use forever – not a fragile service.
The Timeline: How Soon is ‘As Soon As Possible’?
Quantum breakthroughs aren’t tomorrow, but they’re not decades away. Google’s Willow has 105 qubits. Experts say 1-10 million qubits might be needed to break crypto. NIST is standardizing post-quantum algorithms now.
For Ethereum, upgrades could come via hard forks. Early tests exist, like Ethereum’s PQ research. But full rollout needs community buy-in. Delaying risks a rush job later, with bugs or lost funds.
Real-World Impacts
- Users: Secure holdings for generations. Sleep easy knowing ETH is quantum-safe.
- DeFi and NFTs: Protocols stay trustless. No quantum hacks wiping billions.
- Investors: Ethereum’s price could rise on maturity news. Shows leadership over rivals.
How Ethereum Can Achieve Quantum Resistance
Steps are underway:
| Approach | Pros | Cons |
|---|---|---|
| Upgrade signatures | Protects new transactions | Old addresses vulnerable if public keys exposed |
| Address format change | Hides public keys | Requires wallet migration |
| Hybrid crypto | Classical + quantum-safe | Larger data sizes |
Vitalik pushes proactive moves. Ethereum’s history of upgrades like The Merge proves it can adapt.
What This Means for the Crypto World
If Ethereum leads on
Quantum fears aren’t FUD. They’re a call to action. Vitalik’s vision: A protocol that lasts 100 years, powering finance, governance, and more – without babysitters.
