Legacy - Digital Signatures

Introduction

Overall, there are three foundational concepts that, if understood well, can make the initial learning journey for the BSV blockchain (BSV) much easier. While the two other concepts are Hash Functions and Merkle Trees, the focus of this course is to cover the third concept - Digital Signatures.

As this is a beginner-level course, it assumes no knowledge of BSV. There are many well-proven Digital Signature Schemes such as RSA (based upon the name of its inventors Rivest-Shamir-Addlemen), Digital Standard Signature, ECDSA (Elliptic Curve Digital Signature Algorithm), used by enterprise products. For the scope of this course, our focus will only be on ECDSA as used in BSV. In order to build a solid conceptual understanding, the course will progress in the following order: Chapter 1 - What are Digital Signatures? Chapter 2 - ECDSA Pre-requisites Chapter 3 - ECDSA Chapter 4 - Bitcoin and Digital Signatures
