Abstract
Quantum computing is an emerging technology that promises unprecedented computational power, potentially revolutionising various industries. Despite its potential to deliver significant benefits to the adopting organisations, quantum computing may also be used to break current forms of encryption and, as such, represents a threat for the security of current information systems that rely on cryptography to ensure the confidentiality and integrity of information. This is particularly the case for blockchain which relies heavily on cryptographic protocols for security and consensus, and has been extensively used for processing financial transactions in the form of cryptocurrencies. This research aims to investigate the impact of quantum computing on blockchain technology by summarising the present body of academic literature at the intersection between blockchain and quantum computing through a systematic literature review. Based on the findings of the literature review, an empirical analysis is conducted to assess the impact of the implementation of state-of-the-art post-quantum algorithms on the performance of various mainstream blockchains. This research aims to contribute to the development of quantum-safe blockchain systems by providing valuable insights for organisations that aim to adopt post-quantum blockchain-based information systems.
