MicroAlgo Inc. (NASDAQ: MLGO) announced the development of a quantum blockchain architecture that incorporates cyclic quantum secure communication and quantum key distribution technologies to enhance transaction security and transparency.

The architecture features a four-layer design structure. The quantum communication layer implements cyclic QSC and QKD technologies to provide secure communication and key distribution for blockchain network nodes. The blockchain core layer maintains network stability using distributed ledger technology and quantum encryption for transaction data protection.

The smart contract layer provides an execution environment supporting user-defined transaction rules, incorporating quantum signature technology for contract security. The application layer serves as the interface for users to interact with the blockchain network and offers API interfaces for third-party developers.

According to the company's statement, the quantum key distribution technology ensures security in key generation and distribution, while quantum encryption protects transaction data against quantum computing threats. The system includes periodic key updating and rotation for long-term security maintenance.

The company acknowledged that the promotion and application of the architecture face challenges, noting that quantum technology maturity and commercialization require further development to support large-scale applications.

MicroAlgo, based in the Cayman Islands, develops central processing algorithms and provides solutions that integrate algorithms with software and hardware components. The company offers services including algorithm optimization, computing power acceleration, and data intelligence services.
