Ethereum Shouldn't Delay Preparing for Quantum Computing Threat, Says Vitalik Buterin

Ethereum co-founder Vitalik Buterin has called for immediate action to ensure the blockchain remains secure in the face of future quantum computing threats. In a recent statement, he emphasized the need for the network to pass a 'walkaway test,' meaning Ethereum should continue to function safely and usefully even if all core developers and infrastructure teams disappear according to Buterin's proposal.

Buterin argued that Ethereum must evolve into a system that does not rely on constant protocol upgrades. He proposed a vision where the network's value proposition is built into its base layer, allowing it to remain stable and functional without requiring ongoing human intervention as detailed in his analysis.

To achieve this, Buterin outlined several nonnegotiable upgrades, including full quantum-resistance. He stressed that delaying these changes would expose the network to unnecessary risk as quantum computing technologies advance according to his recommendations.

Why Did This Happen?

The call for quantum-resistant updates follows heightened concerns across the crypto industry. In recent weeks, multiple experts have warned about the risks quantum computing poses to current cryptographic systems. These concerns are not limited to Ethereum; Bitcoin and other blockchains also face similar threats as Coinbase's executive warned.

Buterin's vision is inspired by a broader need to ensure long-term blockchain resilience. He emphasized that Ethereum should not be treated like a service that ceases to function if its developers stop updating it. Instead, it should act more like a durable tool, such as a hammer that continues to work regardless of the vendor's status according to his plan.

How Did Markets React?

Ethereum's price remains under pressure as the broader crypto market struggles with low demand and fear-driven sentiment. As of January 12, 2026, Ethereum is trading below $3,100, with technical indicators suggesting continued weakness. The RSI is near 50 on the daily chart, while the MACD histogram is fading, indicating waning bullish momentum according to market analysis.
