Conference Paper Description

Blockchain technology is widely used across various domains for its security and distributed ledger capabilities. To secure transactions, most blockchain platforms such as Ethereum employ the Elliptic Curve Digital Signature Algorithm (ECDSA). However, the use of ECDSA can pose risks, such as the inadvertent exposure of the private key in case of errors, thus facilitating obtaining corresponding signatures for various documents. To address this issue, a solution emerges: the integration of the Edwards-curve Digital Signature Algorithm (EdDSA). By opting for EdDSA to generate transaction signatures, several advantages emerge, such as increased speed, optimal performance, and enhanced independence in random number generation. Indeed, this innovative proposition significantly bolsters security compared to the conventional use of ECDSA, marking a substantial advancement within the Ethereum ecosystem. Furthermore, we have implemented both algorithms to sign and verify Ethereum transactions to make a performance comparison. The implementation is carried out in Python on an Intel Core i3 processor with 8 GB of RAM and a 64-bit operating system.
