The threat of quantum computing to existing public key encryption systems is rapidly approaching from theoretical speculation to reality. On February 26, 2026, Ethereum co-founder Vitalik Buterin officially announced a quantum resistance roadmap, explicitly proposing to upgrade cryptographic components across four core layers: consensus, data availability, user accounts, and zero-knowledge proofs. This is not just an update to technical documentation but also marks a critical turning point for the second-largest public blockchain by market capitalization, as it moves from researching quantum threats to actively initiating engineering defenses.
This article will objectively analyze the technical details, evolutionary logic, and potential impact of this roadmap, based on Gate market data and the latest Strawmap plan. As of February 27, 2026, Ethereum (ETH) is priced at $2,037.58, with a 24-hour trading volume of $45
