What is quantum blockchain and do we need it?

Quantum blockchain is a new concept that combines cutting-edge advancements in quantum computing and blockchain technologies. Unlike traditional systems, which are protected by cryptography, quantum blockchain uses quantum algorithms, promising to significantly increase transaction security and speed. But is this technology necessary today? Some experts believe that quantum computers will be able to crack existing security systems, and preparing for this could become an important step in the future. However, at present, the mass implementation of quantum blockchain is not urgently required. Nevertheless, the first prototypes are already emerging, which could change the world of digital finance.
