Key Highlights
- Algorand called for industry-wide post-quantum cryptography standards.
- The focus is on securing 24-word seed phrase derivation methods.
- Quantum computing could eventually break current blockchain cryptography.
Marc Vanlerberghe, Chief Strategy & Marketing Officer at the Algorand Foundation, emphasized the need for blockchain collaboration to address the looming threat of quantum computing.
In the AllInCrypto Podcast posted on Thursday, Vanlerberghe said post-quantum cryptography cannot be solved independently by individual chains. Instead, the industry must establish a shared standard for deriving quantum-secure private keys from traditional 24-word seed phrases.
“Post-quantum crypto cannot be solved chain by chain,” Vanlerberghe stated. He advocated for an industry-wide consensus on a new derivation scheme to ensure seamless compatibility across wallets, hardware devices, and blockchains.
Why quantum security needs a shared standard
Quantum computers pose a potential risk to current cryptographic systems. Algorithms like Shor’s could eventually break the elliptic curve cryptography used in most blockchains, including Bitcoin and Ethereum, exposing private keys derived from seed phrases. While large-scale quantum attacks may still be years away, proactive measures are essential to protect billions of digital assets.
Traditional 24-word mnemonic seeds (BIP-39 standard) generate private keys through specific derivation paths. A post-quantum scheme would introduce quantum-resistant algorithms, such as those based on lattice problems, hash-based signatures, or multivariate cryptography, while maintaining backward compatibility where possible.
However, implementing these changes unilaterally could lead to compatibility issues, wallet fragmentation, and user confusion.
Vanlerberghe acknowledged that individual projects could develop their own solutions but warned against it. “That’s probably not the best way to go because we want industry-wide consensus,” he explained. He highlighted the importance of hardware wallets adopting the same standard to ensure broad ecosystem support.
Algorand’s collaborative approach
Algorand plans to propose a derivation scheme while actively seeking input from other projects. “We are going to propose a way to do this, but we’re not going to implement it ourselves until there is consensus across the industry,” Vanlerberghe said. He described this as “absolutely critical” for long-term security and interoperability.
The foundation is open to sharing expertise gained over years of development and participating in cross-chain discussions.
Algorand sets 2027 timeline
Last month, the Algorand Foundation outlined a time-bound roadmap to protect its network against future quantum computing threats. Targeting full quantum resistance by the end of 2027, the foundation will upgrade user accounts, wallets, custody solutions, and core protocol components. The first phase of implementation is scheduled to begin in Q3 2026.
This proactive strategy addresses growing concerns over “Q-Day,” the moment when quantum computers could crack current encryption methods. Algorand began exploring post-quantum defenses as early as 2022, positioning itself ahead of regulatory deadlines and industry standards.
Timely execution remains a challenge
Algorand’s proposal highlights the practical challenges of implementing post-quantum security across the blockchain industry. While a common standard could improve compatibility among wallets, hardware devices, and networks, reaching broad agreement among competing blockchain ecosystems may take time.
At the same time, individual projects may continue pursuing their own quantum-resistant solutions, creating the possibility of differing technical approaches until broader standards emerge. How quickly the industry can coordinate on shared implementations may influence the pace of post-quantum adoption across digital asset ecosystems.
