Svmuu, Algorithm development company MicroAlgo Inc. has announced the launch of a quantum-based blockchain architecture that integrates a Cyclic Quantum Secure Channel (QSC) and Quantum Key Distribution (QKD) to enhance transaction security and transparency.
The architecture adopts a four-layer design, comprising the quantum communication layer, blockchain core layer, smart contract layer, and application layer. In this framework, QKD is used for highly secure key generation and distribution, while quantum encryption protects transaction data from theft and tampering, also offering resistance against quantum computing attacks.
Furthermore, the system strengthens long-term security through periodic key rotation and a quantum signature mechanism. Combined with a distributed ledger and consensus mechanism, it ensures data immutability and transaction verifiability, achieving a balance between security and transparency.
However, the company also noted that quantum technology still faces challenges in terms of maturity and commercialization, and large-scale implementation will require more time.
