The most recent quantum computers are capable of decoding secret encryption keys and opening up the network to attack by solving extremely difficult classical cryptography calculations. In contrast to the billions of years of calculation required by conventional computer equipment, they can nearly instantly solve complex mathematical calculations. The emergence of quantum computing and blockchains are two of the main technical developments both in academic and industry domains that are currently in progress. Researchers support the creation of innovative methods that incorporate encryption technology in the post-quantum computing. A lattice was utilized extensively in cryptography and those techniques were employed in both (a) cryptanalysis by utilizing lattice assumption to crack cryptosystems and (b) cryptography by exploiting challenging lattice problems in computational domain. The issues similar to the quantum attack and the execution of post-quantum signature verification in blockchains are a required scientific implementation in today’s world because blockchains have considerably advanced in recent years and learned numerous applications in various fields with the assumption that they will significantly improve their security. This chapter offers the theoretical underpinnings for current research in post-quantum cryptography that aims to integrate safe cryptographic primitives into blockchain technology.
