Quantum computing presents a looming challenge for blockchain security, and one emerging player just landed significant backing to tackle it head-on. A post-quantum cryptography startup has secured $20 million in Series A funding, reaching a $120 million valuation as it develops infrastructure to help crypto networks defend against quantum threats. The firm is collaborating with the Solana Foundation on post-quantum readiness initiatives and technical architecture planning, signaling serious momentum in this critical security frontier. As quantum capabilities advance, the crypto industry's race to implement quantum-resistant protocols is intensifying—and this funding round reflects growing institutional confidence in solving one of Web3's most pressing long-term vulnerabilities.
