Google, Microsoft, Amazon, and IBM are some of the biggest companies currently researching and developing quantum computer technology.
Dr. XinXin Fan, the head of cryptography at IoTeX, recently co-authored a research paper titled Enabling a Smooth Migration Towards Post-Quantum Security for Ethereum. The research paper received a Best Paper award from the 2024 International Conference for Blockchain and argued that hash-based zero-knowledge technology is the most user-friendly way to quantum-proof the Ethereum network and other similar cryptographic systems.
In an interview with Cointelegraph, Dr. Fan explained that the elliptical curve digital signature algorithms (ECDSA) employed in current blockchain systems to sign transactions are quantum-vulnerable. However, this vulnerability can be addressed by attaching a hash-based zero-knowledge proof — such as a zero-knowledge scalable transparent argument of knowledge (ZK-Stark) — to each transaction.
The researcher said this method also ensures the smoothest transition for users — avoiding the complexity of other proposed quantum-resistance methods. “The way we are implementing this allows the user to use their current wallet, but we attach each transaction with a zero-knowledge proof that is quantum-safe,” Dr. Fan said.
“We need to consider both the security aspect and also the usability aspect,” Dr. Fan continued. The researcher stressed that balancing user experience with security needs was key to ensuring a timely migration to post-quantum standards.
