MicroAlgo Releases Quantum Blockchain Architecture, Introducing QKD and QSC to Enhance Security

According to the Wall Street Journal, algorithm development company MicroAlgo Inc. has announced the launch of a quantum technology–based blockchain architecture that enhances transaction security and transparency by integrating cyclic Quantum Secure Channels (QSC) with Quantum Key Distribution (QKD). The architecture features a four-layer design: a quantum communication layer, a blockchain core layer, a smart contract layer, and an application layer. QKD enables highly secure key generation and distribution, while quantum encryption safeguards transaction data against theft and tampering—and remains resistant to attacks from quantum computers.
