Vitalik Buterin, co-founder of Ethereum, addressed the looming threat posed by quantum computing in a conversation about the Epicenter podcast. While many in the crypto industry view quantum attacks as a distant or speculative concern, but Butaline provided a more subtle, data-driven assessment rooted in current research and technical predictions.
Is Ethereum prepared for quantum computers?
According to Buterin, communities can get meaningful clues from forecast markets hosted on platforms such as Metaculus. “Just searching for Metaculus Quantum Computing, “The median answer you get when Quantum Computer is strong enough to break encryption is between 2030 and 2035.” This projected time frame will properly make the emergence of reliable quantum threats within the lifetimes of currently running Ethereum and other blockchain protocols.
But Butarin was careful to distinguish between hype and reality. “There are many glyfts in quantum space,” he warned. While some organizations claim to have quantum computers, they often introduce quantum insulation machines. This could be “technically quantum” in the structure, but it cannot make the kind of operation necessary to pose a real threat to the crypto infrastructure work. “They can’t do anything as interesting as a classic computer can’t,” he revealed.
According to Buterin, the true benchmark of quantum risk is not itself the existence of quantum machines, but the demonstrated ability to implement specific algorithms that break encryption. “What is the biggest number you’re considering using Shor’s algorithm?” emphasised Butaline. “Unless the answer is over 35, that’s not very interesting.” Shor’s algorithm is the leading quantum algorithm that can undermine RSA and other cryptographic standards widely used in blockchain technology. Large applications show fundamental vulnerabilities in systems that rely on public key encryption.
Nevertheless, Buterin acknowledged that real advances have been made in quantum computing research. There have yet to be no breakthroughs to justify panic, but “there are great progress in quantum that resists everything,” he said. The Ethereum community is already preparing for this unforeseen through crypto innovation. “Justin Drake has been working on signatures that are friendly to quantum resistance assemblies,” notes Buterin, highlighting the active development of Quaternary cryptographic primitives within the Ethereum research team.
Buterin concluded with a memo of careful optimism. The community’s proactive attitude about security after Quantum, coupled with the slow, measurable pace of quantum progression, appears to provide a reasonable window of transition.
That optimism gained new momentum last week when the Ethereum Foundation announced a roadmap that embeds ZKEVM directly into Layer 1 within 12 months. The initiative outlined by researcher Sofia Gold in a blog post titled “L1 ZKEVM #1: Shipment of Real-Time Certifications” commits the protocol to validate a concise Stark-based proof of 99% of the mainnet block within a 12-second slot time. By enabling validators so that even solo stakers running “home prover” can validate blocks using quantum resistance proofs, rather than rerunning all transactions, the plan allows the plan to reduce the attack surface of Ethereum if it reaches earlier than the schedule.
At the time of pressing, ETH traded for $3,040.
