Vitalik Buterin says Ethereum (ETH) will achieve quantum resistance soon via post-quantum hash-based signatures in the Strawmap, a four-year Layer 1 (L1) upgrade plan. Why it matters: Quantum computers could break Ethereum’s current encryption; hash-based signatures would close that gap before the threat arrives. Buterin’s confirmation moves quantum resistance from a research topic to a scheduled Ethereum upgrade target. The Strawmap’s six-month fork schedule means quantum-resistant slots could ship within the plan’s first two upgrades
