The quantum computing threat demands action now, not later. While most blockchain networks fixate on near-term updates, Ethereum is plotting a different course—one measured in decades. Through rigorous testing frameworks, Ethereum is charting a path toward quantum resistance and protocol stability. The distinction matters: short-term thinking locks in technical debt; long-term architecture prevents it. As quantum capabilities edge closer, proactive protocol hardening becomes critical infrastructure work. Ethereum's approach reflects a fundamental philosophy—sustainable security beats reactive patches.
