# MicroAlgo Inc. Introduces Quantum-Based Blockchain Architecture

MicroAlgo Inc., an algorithm development company, has announced the launch of a blockchain architecture based on quantum technology. According to ChainCatcher, this new system integrates cyclic Quantum Secure Channels (QSC) and Quantum Key Distribution (QKD) to enhance transaction security and transparency. The architecture features a four-layer design, comprising a quantum communication layer, a blockchain core layer, a smart contract layer, and an application layer. QKD is utilized for the secure generation and distribution of keys, while quantum encryption protects transaction data from theft and tampering, offering resistance to quantum computing attacks. The system also employs periodic key rotation and quantum signature mechanisms to strengthen long-term security. By combining distributed ledger and consensus mechanisms, it ensures data immutability and transaction verifiability, achieving a balance between security and transparency. However, the company acknowledges that challenges remain in the maturity and commercialization of quantum technology, indicating that large-scale implementation will take time.
