StarkWare dropped a quantum roadmap for Starknet this week. It’s a direct challenge to an industry that’s been slow to move on one of the biggest long-term threats to blockchain security.
CEO Eli Ben-Sasson was blunt about it. The crypto industry shouldn’t wait for an external push — regulatory, competitive, or otherwise — to start dealing with quantum computing risks. The message was pretty much: act now, or regret it later. Ben-Sasson didn’t soften the language or bury the urgency in corporate hedging. Quantum computing isn’t a distant hypothetical anymore, and StarkWare seems genuinely frustrated that more of the industry hasn’t treated it that way.
Why Quantum Computing Threatens Blockchain Now
The core problem is straightforward, even if the fix isn’t. Quantum computers, once they reach sufficient scale, can break the encryption algorithms that basically every major blockchain relies on today. Elliptic curve cryptography — the backbone of Bitcoin, Ethereum, and most of the networks built on top of them — was designed for a world where classical computers were the only real threat. Quantum machines operate on fundamentally different principles. They can, in theory, crack those algorithms in a fraction of the time a classical computer would need.
That’s not a bug. It’s a structural vulnerability baked into the cryptographic foundations of the entire industry.
StarkWare’s position is that Starknet, its layer-2 network built on Ethereum, needs to get ahead of that before it becomes a crisis. The roadmap lays out steps to upgrade Starknet’s cryptographic protocols — specifically developing new algorithms designed to resist quantum decryption. It’s not a vague promise. It’s a sequenced plan, though some details on specific timelines and technical implementations weren’t fully disclosed in the announcement.
Starknet’s Plan and the Collaboration Push
The roadmap isn’t just an internal technical project. StarkWare is calling for industry-wide collaboration — explicitly. The company believes that no single firm, no matter how well-resourced, can solve this alone. Quantum resistance has to be a collective effort, or it won’t work at scale.
That’s a fair read of the situation. Blockchain networks are interoperable by design. A quantum-resistant Starknet doesn’t do much good if the Ethereum mainnet it settles on is still vulnerable. Or if the wallets users rely on haven’t upgraded. Or if the bridges connecting different chains are still running old cryptographic standards. The attack surface is enormous, and it spans dozens of companies, protocols, and open-source projects.
StarkWare says it’s pursuing partnerships with other industry leaders to share knowledge and speed up development. Exactly which firms are involved wasn’t spelled out. That’s a gap worth noting — the roadmap sets a direction, but the coalition-building is still in early stages, probably.
And there’s a real question about whether the broader industry will follow. Crypto companies are famously competitive. Getting them to coordinate on anything, even something as clearly important as quantum security, is hard. Priorities shift fast. Funding cycles are short. The threat feels abstract until it isn’t.
What Comes Next for Crypto Security
StarkWare’s push lands at a moment when quantum computing is moving faster than most people in crypto expected. Major technology companies and national governments have been pouring resources into quantum hardware and software research. The timeline to “cryptographically relevant” quantum computers — machines powerful enough to actually break production encryption — is genuinely uncertain, but it’s probably shorter than the five-to-ten-year window that was commonly cited just a few years ago.
Some researchers think it could happen sooner. Others think the engineering challenges are still massive. No one really knows for sure.
What’s clear is that building quantum-resistant cryptography takes time. Designing new algorithms, testing them, getting them audited, deploying them across live networks with billions of dollars in assets — that’s not a six-month project. It’s multi-year work, minimum. Which is exactly why Ben-Sasson’s argument for starting now, rather than waiting for a regulatory mandate or a near-miss incident, makes sense.
StarkWare isn’t the first to raise this alarm. The U.S. National Institute of Standards and Technology has been working on post-quantum cryptography standards for years. Several academic research groups have published quantum-resistant signature schemes. But translating that work into production-ready blockchain infrastructure is a different challenge, and it’s one the crypto industry has been slow to take seriously.
Ben-Sasson wants that to change. The roadmap is StarkWare’s opening move — a public commitment to building the quantum-resistant version of Starknet, and a direct ask for the rest of the industry to get moving too.
Whether that ask lands is unclear. The companies most at risk from quantum threats are also the ones with the most to lose from the cost and disruption of a major cryptographic overhaul. It’s a classic collective action problem.
StarkWare’s roadmap at least puts a number on the ambition: a fully quantum-resistant Starknet, built on new algorithms, developed with industry partners, before quantum computers make the current setup obsolete.

Frequently Asked Questions
What is Starknet’s quantum roadmap?
Starknet’s quantum roadmap is StarkWare’s plan to upgrade Starknet’s cryptographic protocols with new algorithms designed to resist quantum decryption, protecting the network from future quantum computing threats.
Why is StarkWare CEO Eli Ben-Sasson calling for industry collaboration?
Ben-Sasson said the crypto industry shouldn’t wait for external pressure to act on quantum risks, and that building quantum-resistant systems requires collective effort across protocols, companies, and infrastructure providers — not just StarkWare alone.
