In a future quantum world with a large quantum computer, the security of the digital signatures used for Bitcoin transactions will be broken by Shor's algorithm. Bitcoin has to switch to post-quantum cryptography. In this paper, we show that the post quantum signatures based on LWE and ring LWE are the most promising to use in the presence of large quantum computers running Shor's algorithm.
