Abstract: An electronic peer to peer cash system called Bitcoin does not need a third party to transfer digital currency from one to another. This system provides an efficient way of transaction between different users without any question of trust. Digital signature plays an important role in this. It provides security, integrity and non-repudiation for safe and secure transaction. Electronic signature is used to identify authenticate users. Not many authors have proposed the best digital signature algorithm to authenticate Bitcoin transactions. In this study, the well-known digital signature scheme known as ECDSA is compared with RSA and DSA signature schemes to identify the optimal signature scheme for digital currency, Bitcoin.
