A cryptocurrency is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets. The cryptocurrency systems are based on blockchain technology uses the Elliptic Curves Digital Signature Algorithm (ECDSA). The paper proposes a multiple Elliptic Curve Digital Signature Algorithm (mECDSA), which allows multiple signers to select Elliptic Curves (EC) as per requirements. The security and computational analysis of proposed scheme proves that the scheme is secure and efficient then other existing schemes. To optimize security and efficiency it is recommended that two elliptic curves used in the systems based on blockchain.
