Abstract

This literature review explores the state-of-the-art advancements in quantum and post-quantum blockchain. The realm of quantum computing is on the rise and will disrupt entire tech industries, including classical cryptography, which is the foundation of blockchain. There has been extensive research on classical cryptosystems (i.e., post-quantum) and their integration with blockchain to create quantum-resistant classical blockchains. We have reviewed the state-of-the-art in these post-quantum blockchains in academic research. But to have forward compatibility with the quantum internet and infrastructure in the future and to have quantum mechanical security, research has been conducted to implement blockchain on quantum technologies and quantum cryptography as well. Consequently, we have explored the current state of research in these quantum solutions, known as quantum blockchains.
