Abstract : Digital signatures are a vital part of the digital world. The trust factor in the digital world is ensured with a digital signature. Over the evolution, the purpose remained constant, but the applicability and frontier continued to evolve, thus raising the demand for continuous performance, security level and computational improvement. Especially with emerging IoT, blockchain and cryptocurrency, the digital signature security level and performance improvement demand continue to rise. A digital signature scheme (DSS) is used to generate signatures. This paper investigates the widely used elliptic curve digital signature algorithm (ECDSA) and its application to blockchain and IoT. Then, we performed an empirical comparison of ECDSA with the Edwards curve digital signature algorithm (EdDSA). The study concludes by showing that EdDSA is superior to ECDSA and can be applied in blockchain and IoT domains to reap immediate benefits
