Problem
Current cryptographic algorithms and blockchain security rely on mathematical problems that can be efficiently solved by emerging quantum computers, creating a future risk of data breaches and compromised digital trust. Enterprises also lack access to true high‑entropy randomness, which is essential for secure key generation and encryption, and existing solutions are either costly or vulnerable to interception.
Solution
Quantum Blockchains provides a suite of quantum‑safe cryptographic products that combine genuine quantum key distribution (QKD) emulation, post‑quantum algorithms, and quantum random number generation (QRNG). Its patented pQKD device emulates QKD protocols while integrating NIST‑approved post‑quantum key‑exchange mechanisms, enabling secure key establishment for networks, VPNs, and blockchain nodes without requiring dedicated fiber infrastructure. The company also offers a Quantum Entropy‑as‑a‑Service API that aggregates four independent QRNG sources, delivering high‑entropy random numbers in multiple formats for passwords, keys, and blockchain mnemonics. These components are integrated into a Quantum Secured Blockchain (QSB) architecture that uses QKD‑based channel security, post‑quantum digital signatures, and true quantum entropy to protect transaction integrity against quantum attacks. Additionally, the Quantum Cryptography Migration System (QCMS) facilitates a cost‑effective transition from legacy cryptography to quantum‑resistant solutions, allowing organizations to adopt quantum security incrementally.
Target Audience
Primary customers are enterprises and infrastructure providers that require quantum‑resistant security for data centers, network communications, and blockchain deployments, as well as industrial operators integrating secure communications for autonomous robots and Industry 4.0 systems.
