Vitalik Buterin Says Ethereum Will Soon Achieve Quantum Resistance

Vitalik Buterin says Ethereum (ETH) will obtain quantum resistance quickly by way of post-quantum hash-based signatures within the Strawmap, a four-year Layer 1 (L1) improve plan.

Why it issues:

• Quantum computers may break Ethereum’s present encryption; hash-based signatures would shut that hole earlier than the risk arrives.
• Buterin’s affirmation strikes quantum resistance from a analysis matter to a scheduled Ethereum upgrade goal.
• The Strawmap’s six-month fork schedule means quantum-resistant slots may ship inside the plan’s first two upgrades.

The particulars:

• Buterin confirmed the timeline by way of X on February 26, 2026, citing the Ethereum Foundation’s Strawmap.
• The Strawmap was printed at strawmap.org after an Ethereum Foundation workshop in January 2026.
• The identify blends “strawman” and “roadmap,” which means the plan is experimental and constructed to be revised.
• The four-year plan targets ~7 forks each six months; Glamsterdam and Hegotá are confirmed for 2026.
• Buterin additionally proposed slicing block time to 2 seconds and finality from ~16 minutes to six–16 seconds.

The massive image:

• Bitcoin and Solana ecosystems are additionally operating post-quantum analysis, making it a rising precedence throughout blockchains.
• A hard and fast six-month fork schedule marks a sooner, extra structured improve cadence for Ethereum’s L1.
• The Strawmap is explicitly a draft — timelines, together with quantum resistance, may shift as growth progresses.
