Vitalik Buterin, Ethereum’s cofounder, is once again warning about the growing threat of quantum computers, but this time he has actually outlined a plan to fight it.

He has talked about this risk many times before, and it is becoming a bigger concern for the entire crypto market. How exactly? Your crypto wallet’s private key is protected by a math problem called elliptic curve multiplication.

Right now, no normal computer on Earth can break that key. It would take billions of years. Quantum computers are different. They use something called Shor’s algorithm, which is designed to break this specific kind of math.

If someone builds a large enough quantum computer with stable qubits, it could calculate your private key from your public address in hours, maybe even minutes.

Vitalik Buterin’s Emergency Plan To Resist Quantum Computers

Citing forecasting platform Metaculus, Buterin said there is “about a 20% chance” that quantum computers capable of breaking today’s cryptography could arrive before 2030, with the median estimate closer to 2040.

Quantum progress is speeding up fast as companies and governments pour billions into the field. Buterin’s quantum emergency plan includes rolling back blocks, freezing EOAs, and migrating funds into quantum-resistant smart contract wallets.

That last part is what most experts focus on. These upgradeable smart contract wallets, often called account abstraction wallets, can switch to quantum-proof signatures the moment those signatures become available. Anyone can already move to one of these wallets today.

But what if a quantum breakthrough arrives suddenly? Long before these recent public warnings, Buterin outlined a 2024 Ethereum Research post called “How to hard-fork to save most users’ funds in a quantum emergency.”

In that scenario, Ethereum would trigger an emergency hard fork. The network would detect theft through on-chain monitoring, roll the blockchain back to the last safe block (rewinding hours or even days of transactions), and freeze vulnerable EOAs to prevent attackers from draining more funds.

So, Is Ethereum Safe?

Yes, Ethereum is still extremely safe today. But quantum computers could eventually break some of the deeper math that Ethereum relies on for fast Layer 2s and zero-knowledge proofs. That is why the real fix is not just upgrading wallet keys, it is replacing those underlying cryptographic components too.

The scariest “what if” scenario is a sudden quantum breakthrough that starts draining billions overnight. Vitalik’s backup plan for that is an emergency hard fork to pause the damage and move everyone’s money to new safe wallets, but everyone knows that would be messy and controversial.

This is exactly why he does not want to wait for a crisis. The goal is to let people slowly move to upgradeable smart-contract wallets long before quantum computers become a real threat, so almost no one is still using the vulnerable legacy format when the time comes.

For you right now, staying safe is simple: use a modern smart-contract wallet, don’t reuse the same address forever, and keep an eye on official Ethereum updates. Do that, and quantum computers will remain a nerdy future problem, not your problem.

Ethereum Price Prediction: December For ETH

November has been one of the worst months for ETH. Spot Ethereum ETFs faced an outflow exceeding $1.42B, setting a new historical record for these funds.

Right now, Ethereum is sitting around 2,829 dollars, just a bit above the same support zone it bounced from last time. The first rebound got rejected at 3,000, and ETH might be gearing up to retest that level again if it can keep holding above support.

A clean break above 3,000 would open the door to a move toward the next resistance around 3,500. The RSI sitting near 40 plus rising volume shows momentum is trying to rebuild, but holding this support zone is the whole game. If ETH slips below it, things can get a lot uglier for both Ethereum and the rest of the altcoins.

Bitcoin Hyper Closing On $29M: Is This The Next Big Layer 2?

Bitcoin Hyper is pulling in serious momentum at a time when Ethereum is dealing with everything from quantum security worries to record ETF outflows. And while ETH tries to hold its support zone, Bitcoin Hyper is moving in the opposite direction with a presale that keeps accelerating.

The project has already raised more than 28.8 million dollars, which is not something you normally see during a shaky market month. Early buyers are locking in a steady 40% APY through staking, and that predictable yield is becoming a magnet for investors who want upside without drowning in volatility.

With Bitcoin Hyper building a lightning-fast Bitcoin Layer 2 using SVM, plus the combination of real yield and massive early demand, the presale is shaping up to be one of the strongest narratives heading into 2025.
