# Legacy - Digital Signatures

{% embed url="<https://youtu.be/4JlmLePwlp0>" %}

### 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<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hub.bsvblockchain.org/higher-learning/bsv-academy/digital-signatures.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
