A Survey on Post Quantum Digital Signature Schemes for Blockchain

Blockchain has become one of the most cutting-edge technologies, which has been widely concerned and researched. Current blockchain platforms rely on digital signatures, which are vulnerable to attacks by means of quantum computers. The security of blockchains can be enhanced by using post-quantum digital signature schemes for signing transactions. Such schemes are considered to be robust against attacks with quantum computers. In this paper a survey on the existing post-quantum digital signature schemes is done.
