Dr. XinXin Fan, the cryptography expert at IoTeX, has collaborated on a groundbreaking research paper titled “Enabling a Smooth Migration Towards Post-Quantum Security for Ethereum.” This award-winning paper, presented at the 2024 International Conference for Blockchain, introduces hash-based zero-knowledge technology as the ultimate solution to quantum-proof the Ethereum network and similar cryptographic systems.
In an exclusive interview with Cointelegraph, Dr. Fan highlighted the vulnerability of current blockchain systems, particularly the elliptical curve digital signature algorithms (ECDSA), to quantum attacks. To combat this threat, Dr. Fan proposes the integration of hash-based zero-knowledge proofs like zk-STARKs into transactions. This not only enhances security but also ensures a seamless transition for users, eliminating the complexity associated with other quantum-resistance methods.
Dr. Fan emphasized the importance of balancing security and usability to facilitate a timely migration to post-quantum standards. The research aims to provide end-users with a user-friendly experience while safeguarding the network against quantum threats.
With the National Institute of Standards and Technology (NIST) setting a deadline for legacy systems to adopt post-quantum standards by 2035, the urgency of implementing quantum-resistant measures is paramount. Recent reports of successful cryptographic breaches using quantum computers underscore the pressing need for advanced security measures in blockchain systems.
Despite the hype surrounding quantum computing’s threat to encryption, experts suggest that the current capabilities of quantum computers fall short of cracking modern encryption standards. The divergence between quantum computing power and encryption key lengths indicates that the perceived risk may be overstated at this juncture.
