Quantum is the first decentralized platform for cryptocurrency trading on the quantum blockchain. The quantum network is also a decentralized application platform, compatible with the existing blockchain infrastructure, and has a modular structure, so new technologies can always be added.

In a quantum block chain network, each node stores a copy of the block chain. As in the classic block chain, the goal of this stage is to add valid blocks in a decentralized manner. The problem with building a quantum blockchain network is that the network may consist of unscrupulous nodes, and the generated blocks may come from an unscrupulous source. Quantum-secure certificates are X. 509 certificates that use quantum-secure encryption algorithms. Although NIST is still in the process of standardizing quantum-secure encryption algorithms, it has identified a number of candidate algorithms, and implementations are currently available.
