Blockchain technology has revolutionized the world of digital transactions, enabling secure and transparent peer-to-peer exchanges without the need for intermediaries. At the heart of this technology lies cryptographic algorithms, particularly signature algorithms, which ensure the authenticity and integrity of data on the blockchain. In this article, we will dive into three popular blockchain signature algorithms: ECDSA, EdDSA, and Schnorr. 🚀 ECDSA: Elliptic Curve Digital Signature Algorithm ECDSA (Elliptic Curve Digital Signature Algorithm) is a widely adopted cryptographic algorithm in the blockchain realm.
