Abstract
Blockchain is based on complex mathematical methods such as public key cryptography, hash functions, and digital signatures. They ensure the security and immutability of data. The question arises – which of the elliptic curve digital signature algorithms provides the optimal balance between speed, attack resistance, and compactness in the blockchain environment? The Schnorr algorithm demonstrates higher performance, reduced signature size, and improved support for multisignature schemes compared to traditional ECDSA, making it a promising choice for next-generation blockchain protocols. Therefore, a critical analysis of the efficiency and robustness of digital signature algorithms based on elliptic curves (ECDSA, EdDSA, Schnorr) in the context of blockchain technology is the task of this work, aimed at assessing their suitability for modern security and performance requirements.
