Blockchain's Quantum Leap Forward May Be Undone By Artificial Intelligence, Says Solana Mastermind

Table of Contents Post-quantum cryptography risk has emerged as a pressing concern for blockchain networks, with Solana co-founder Anatoly Yakovenko raising alarms about the long-term security of cryptographic systems. His warning covers wallets, transactions, and network integrity across the broader crypto industry. The concern is forward-looking but gaining urgency as quantum computing research advances steadily. Yakovenko took to X to share his concerns about post-quantum cryptographic systems. He argued that the biggest risk is that AI could break post-quantum cryptography (PQC) signature schemes. His position as Solana’s co-founder gives his warning considerable weight among developers and researchers. I think the biggest risk is that pqc signature schemes will get broken by ai, we don’t know all the implementation footguns even, let alone the math footguns. So we need to support 2/3 wallets for them. @fusewallet or ideally natively with PDAs in the tx processor. — toly 🇺🇸 (@toly) May 2, 2026 He pointed out that the industry lacks full understanding of the mathematical vulnerabilities in these schemes. Beyond that, hidden dangers in practical deployment remain unclear, adding another layer of concern. These gaps make it harder for blockchain networks to confidently transition to quantum-resistant cryptography. To address this, Yakovenko proposed practical solutions for securing networks during any transition period. He suggested providing 2/3 multi-signature wallet support for post-quantum schemes. He also recommended native support through Program Derived Addresses (PDAs) within transaction processors as a stronger alternative. In his post, Yakovenko tagged @fusewallet, indicating interest in collaboration on this issue. His comments reflect a broader push within the Solana ecosystem to treat quantum readiness as a technical priority. The call to action is aimed at developers building wallet infrastructure today. Solana’s engineering arm, Anza, has already published research on securing the network against powerful quantum adversaries. The research explores how Solana could transition to quantum-resistant schemes while maintaining its performance standards. This groundwork shows that the concern is moving from theory into active planning. The challenge extends well beyond Solana. Every blockchain relying on ECDSA or EdDSA signatures faces the same long-term exposure. Bitcoin, Ethereum, and other major networks all use public-key cryptography that a sufficiently capable quantum computer could theoretically compromise. Ethereum has also outlined a quantum resistance roadmap as part of its long-term strategy. The parallel efforts across major protocols suggest post-quantum preparedness is becoming a standard expectation. Projects that demonstrate a clear migration path may hold a credibility advantage with institutional investors. The core difficulty lies in coordinating a cryptographic migration across millions of wallets and smart contracts. This must happen without disrupting active network operations, which makes the process technically complex. Networks that begin preparing earliest will be in the strongest position when quantum computing capabilities mature further.
