Vitalik Buterin, co-founder of Ethereum, advocates for the stabilization of Ethereum's core protocol, emphasizing that the base layer should ossify to prevent bugs and promote ecosystem stability. He suggests shifting innovation to layer 2 solutions like rollups and privacy tools, allowing the main blockchain to become more secure and less prone to surprises. Buterin warns that elliptic curve cryptography, the foundation of Ethereum and Bitcoin security, could be vulnerable to quantum computing attacks before the 2028 US presidential election, urging the ecosystem to migrate to quantum-resistant cryptography within the next four years. Meanwhile, advancements in quantum computing pose a significant future threat to Bitcoin and other cryptographic systems. The CEO of Alice & Bob, a quantum computing firm backed by Nvidia, predicts that quantum computers could crack Bitcoin's security after 2030 by solving complex encryption and mining mechanisms. Although current quantum computers are not yet powerful enough, ongoing development aims to create fault-tolerant quantum systems like 'Graphene' by 2030, which could outperform classical supercomputers at non-trivial tasks. This exponential increase in quantum power could compromise blockchain security, prompting the need for proactive upgrades to cryptographic protocols.
