A blockchain infrastructure startup just wrapped up $20 million in Series A funding at a $120 million valuation, with plans centered on preparing crypto networks for quantum computing threats. The initiative focuses on building quantum-resistant cryptographic solutions to shield existing blockchain architectures from potential attacks as quantum technology advances. This funding round highlights growing industry concern about long-term security vulnerabilities in current consensus mechanisms and address schemes. With quantum computers still emerging, projects tackling post-quantum cryptography are positioning themselves as critical infrastructure for future-proofing decentralized networks against what many consider an inevitable technological shift.
