Ethereum co-founder Vitalik Buterin has announced a comprehensive strategy to enhance the network's security and performance in anticipation of quantum computing threats. The plan, described as a "Ship of Theseus" overhaul, aims to integrate post-quantum cryptography to boost transaction speeds and fortify the blockchain against potential quantum breakthroughs. Buterin's "bundle" strategy involves pairing consensus upgrades with a transition to quantum-resistant security protocols, including post-quantum hash-based signatures and STARK-friendly hashes. This approach is designed to seamlessly replace vulnerable cryptographic foundations as part of broader performance enhancements. Buterin highlighted that while the network may achieve quantum resistance for basic block production before finality, it provides a fail-safe against sudden advancements in quantum computing technology. Buterin has previously estimated a 20% chance of quantum computers capable of breaking current cryptography emerging before 2030, underscoring the urgency of Ethereum's proactive measures.
