The quantum clock is ticking: it's Bitcoin's problem, not Ethereum's

Summary

The core claim is that quantum computing makes bitcoin materially riskier than Ethereum, and this difference comes from both cryptography and governance. Recent analysis from Google Quantum AI and Citi suggests bitcoin’s elliptic-curve signatures may be breakable sooner than expected, while Ethereum has a more flexible path to post-quantum security. Bitcoin’s design exposes public keys when transactions are made, and upgrading its base layer would require slow, contentious consensus. Proposed quantum-fix changes are still early, making timely migration uncertain. Ethereum, by contrast, is already moving toward post-quantum standards through account abstraction and planned protocol upgrades. Its roadmap is structured, active, and aligned with NIST standards, making it easier for users and institutions to adopt quantum-safe signatures over time. For institutional treasury holders, the conclusion is that bitcoin’s quantum risk is an urgent governance problem, while Ethereum appears more adaptable and durable.
