Blockchains and the emergence of quantum technologies are two of the most significant emerging technical developments now underway that are demonstrating an ever-increasing spread both in academic and industrial domains. The problem related to the quantum threat and the execution of post-quantum signatures in a blockchain platform is a hot topic in today’s scientific community because blockchains have remarkably progressed in recent years and have found a variety of applications with the assumption that they will drastically increase their safety. The most recent quantum computers are capable of decoding secret encrypted keys and opening the network to attack by solving very difficult classical cryptography equations. In contrast to the billions of years of calculation required by conventional computer equipment, they can nearly instantly answer complicated mathematical problems. Researchers support the creation of innovative methods that incorporate encryption technology in the post-quantum future. Quantum computing, post-quantum cryptography, quantum attack-resistant blockchain, quantum blockchains, interdisciplinary solutions, and real-world use cases are just a few of the themes that are taken into account in the book Advances in Quantum Blockchain with Real-Time Applications. A distributed database that is based on quantum information theory and computing is known as a quantum blockchain. It is decentralized, encrypted, and distributed. The necessity for quantum versions of conventional blockchains and current developments in quantum computing are the causes of this. Quantum blockchain is one of several technologies still in the process of standardization, including algorithms, platforms, models, applications, systems, and databases. There is now more study being done in this area as a result of the development of quantum information theories and computation.
