Towards fast ECC signing algorithms for Blockchain

Blockchain (BC) is a revolutionary technology that has dramatically impacted modern society thanks to its decentralization, transparency, and security properties. The BC is a distributed database that stores a register of assets and digitally signed transactions. Beginning in the financial field, BC was quickly applied to several fields, including the Internet of Things (IoT), supply chain, education, healthcare, and energy. In most BC-based applications, transactions are signed using ECDSA or EdDSA algorithms. However, scalar multiplication (SM) is a complex and central operation in these signing algorithms. This paper presents the most efficient techniques for computing SM to provide fast signature algorithms for BC-enabled applications.
