StarkWare CEO Eli Ben-Sasson addressed the potential impact of quantum computing on the crypto industry on X, urging multi-chain ecosystems, including Bitcoin, to proactively deploy post-quantum security upgrades and proposing a five-step action plan: 1. Acknowledge the threat: Once quantum computers mature, they will pose a serious challenge to existing public-key cryptography systems, and decisively implement countermeasures. 2. Strengthen education and information dissemination: Systematically learn about the current state of quantum computing development and feasible post-quantum cryptography (PQC) solutions, and popularize relevant knowledge within the community to improve overall awareness. 3. Invest resources: Support and collaborate with post-quantum cryptography experts to promote multiple research and engineering practices, providing funding and community initiative support for related projects. 4. Listen to expert advice and develop standards: Experts should propose specific technical routes, including the selection of new signature algorithm standards and the appropriate post-quantum security level required for hash functions. 5. Promote protocol and infrastructure upgrades: Introduce new quantum-resistant signature mechanisms at the core protocol layer and ensure compatibility and integration with critical infrastructure such as wallets to ensure a smooth transition.
