Quantum IT, often perceived as a sword of damocles suspended above blockchains, has funed fantasies and speculations for more than a decade. In this universe of uncertainty, Vitalik Buterin, co-founder of Ethereum, comes to make a diagnosis against the tide: lucid, encrypted, but above all confident. For him, the arrival of machines capable of breaking the current cryptographic foundations is not inevitable, it is a deadline. And Ethereum will be ready there.
In short
- Vitalik Buterin believes that quantum computer science does not threaten Ethereum before 2035.
- The Ethereum community is already developing post-quantic cryptographic solutions.
- A native ZKEVM will be integrated into layer 1 to strengthen safety and scalability.
Vitalik Buterin: Lucidity in front of the quantum fog
During his passage in the podcast SparkleVitalik Buterin decided in the myth: no, quantum computer science will not have Ethereum implode overnight. What he opposes to ambient alarmism is an implacable analytical rigor, supported by the aggregated forecasts of platforms like Metaculus. According to these, the critical threshold, the one where a quantum machine could break cryptography, is between 2030 and 2035.
But Buterin is not content to launch numbers in the air. He carefully distinguishes scientific advances from marketing blows. Because in the quantum world, the swarming is commonplace. Many so-called quantum computers are actually only gadgets unable to execute true threatening algorithms for modern cryptography.
The key indicator, According to him ? The greatest number that we have managed to de factor with the Shor algorithm. As long as this figure does not exceed 35, networks like Ethereum can sleep on their two ears.
A strategic anticipation already on
What distinguishes Ethereum in this race against the clock is not only vigilance, but active preparation. Buterin underlines the concrete efforts of the ecosystemstarting with Justin Drake's work on signatures Aggregation-friendly resistant to quantum attacks.
Far from waiting for the storm to react, Ethereum advances against the tide with structural solutions. The recent roadmap published by the Ethereum Foundation announces the direct integration of a ZKEVM within layer 1, within twelve months. This choice is not trivial: it is based on succinct evidence Stark, the very nature of which is resistant to quantum computers.
The stake is twofold: accelerating scalability while drastically reducing the attack surface of the network. With verifiable proof in less than 12 seconds, even an individual validator will be able to protect the network against sophisticated attacks, all without replaying transactions one by one. A technical feat, but above all a daring strategic anticipation. This may be what appeals to investors. To the point of making it the number one choice of Crypto ETF.
