Abstract: This study conceptually investigates the impact of quantum computers on blockchains within the supply chain context. Powerful quantum computers enable attackers to break into blockchains by rapid inverse calculations of mathematical problems that are the core of one of the main blockchain security foundations, known as asymmetric cryptography. They are also able to violate the integrity of public blockchains like bitcoin through mining acceleration. Hence, quantum computers can engender threats to the supply chain users of blockchain. On the other hand, there are ongoing efforts to create a quantum-resistant solution. One approach for such a solution is to utilize quantum tools themselves. Moreover, sufficiently powerful quantum computers are still being developed, and it is still unclear whether a quantum solution will arrive first or vice versa. The contrasting duality of quantum computers and lack of a clear picture over the timing of the arrival of a solution and threats give rise to the uncertainty that might hinder the attractiveness of blockchains for supply chains.
