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

ChainCatcher reports that algorithm development company MicroAlgo Inc. has announced the launch of a blockchain architecture based on quantum technology. By integrating cyclic quantum secure channels (QSC) with quantum key distribution (QKD), the architecture aims 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. QKD is used to achieve highly secure generation and distribution of keys, while quantum encryption protects transaction data from theft and tampering, and also provides resistance against quantum computing attacks. Additionally, the system reinforces long-term security through periodic key rotation and quantum signature mechanisms, and combines distributed ledger and consensus mechanisms to ensure data immutability and transaction verifiability, achieving a balance between security and transparency. However, the company also pointed out that quantum technology still faces challenges in terms of maturity and commercialization, and widespread adoption will require more time.
