New Blockchain Consensus Algorithm for Energy Efficiency and Quantum Resistance

Abstract

In recent times, blockchain has captured the attention of diverse entities, including businesses, institutions, and organizations, all of which underscore the importance of decentralization. Blockchain, a distributed computing technology heavily reliant on cryptography, empowers users to generate and validate blocks on an equal footing without the intervention of a central server. Each user employs their cryptographic key as an identification method for this purpose. Due to these characteristics, cryptographic security assumes significant importance in the realm of blockchain. Regrettably, the current digital signature technology utilized for transaction generation in blockchain is vulnerable to the easy compromise of private keys through quantum computing algorithms. Consequently, there arises a pressing need for research on cryptographic systems that are secure against quantum computers. This thesis introduces the application of post-quantum digital signature algorithms in blockchain consensus protocols to effectively address this vulnerability.
