A co-founder of Project Eleven says AI is finding cracks in post-quantum cryptography, the very class of algorithms the digital-asset industry is counting on to survive the arrival of quantum computers. The warning, issued this week, argues that AI's ability to surface vulnerabilities is accelerating the need for security systems that can adapt on the fly rather than lock in once and hope.
The message is uncomfortable for a sector that has spent years treating post-quantum migration as a future chore. If the tools meant to replace today's encryption are already showing weakness under AI-assisted scrutiny, the runway is shorter than most assumed.
The cracks aren't theoretical
Project Eleven's co-founder didn't frame the problem as a distant threat. The point is that AI changes the pace of vulnerability discovery itself — it can comb through code and mathematical structures faster than human researchers, which means flaws in post-quantum schemes may surface sooner and more often than the standards process anticipated.
That's a different risk profile from the one the industry has been planning around. Most post-quantum roadmaps assume the algorithms hold up while deployment catches up. The warning suggests the assumption deserves a second look.
Why adaptive beats fixed
The co-founder's argument leans on adaptability: digital asset protection can't rest on a single algorithm choice made years in advance. Systems need to swap cryptographic primitives as weaknesses emerge, which is easier said than done for wallets, exchanges and custody providers built around long-lived key material.
For crypto specifically, the stakes are awkward. Public blockchains store keys and signatures in the open, and any migration to new cryptography means coordinating across users, node operators and infrastructure providers who don't share a schedule.
A sector already behind
Post-quantum readiness across digital assets has been slow. The industry has talked about migration for years, but actual deployment of quantum-resistant signatures remains limited, and the Project Eleven warning lands as a reminder that the problem isn't only the quantum computer — it's the cryptography the industry plans to replace its current stack with.
AI cutting into that replacement layer complicates the story further. If the new algorithms need patching before they're widely adopted, the migration target keeps moving.
What comes next
Project Eleven hasn't published a specific remediation plan or timeline, and the co-founder's warning is a call for adaptive security rather than a detailed technical fix. The immediate question is whether crypto infrastructure teams treat AI-assisted vulnerability discovery as a design constraint now, or wait for a concrete break to force the issue.
For now, the warning stands as one more item on a security agenda that already has plenty.
