MicroAlgo releases its quantum blockchain architecture, introducing QKD and QSC to enhance security.

MicroAlgo Inc., an algorithm development company, announced the launch of a quantum-based blockchain architecture that enhances transaction security and transparency by integrating cyclic quantum secure channels (QSC) and quantum key distribution (QKD). The architecture employs a four-layer design, including a quantum communication layer, a blockchain core layer, a smart contract layer, and an application layer. QKD is used for highly secure key generation and distribution, while quantum encryption protects transaction data from theft and tampering, and is resistant to quantum computing attacks. Furthermore, the system strengthens long-term security through periodic key rotation and quantum signature mechanisms, and combines distributed ledgers and consensus mechanisms to ensure data immutability and transaction verifiability, achieving a balance between security and transparency. However, the company also points out that quantum technology still faces challenges in terms of maturity and commercialization, and large-scale deployment will take time.
