What are Cryptocurrencies?

Module 1.1: Definition of Cryptocurrencies

Lesson 1.1.1: Understanding Cryptocurrencies

In this lesson, we will explore the fundamental concepts of cryptocurrencies:

Cryptocurrency Definition:

Cryptocurrencies are digital or virtual currencies that use cryptographic techniques for secure and transparent transactions. They exist purely in electronic form and do not have a physical counterpart.-

Historical Background:

We’ll delve into the history of cryptocurrencies, starting with the creation of Bitcoin by an anonymous entity known as Satoshi Nakamoto in 2009. Understanding the origins helps us appreciate the evolution of this technology.

Lesson 1.1.2: Key Characteristics

In this lesson, we’ll examine the core characteristics of cryptocurrencies:

Digital Nature:

Cryptocurrencies are entirely digital, stored electronically in digital wallets. This characteristic enables easy online transactions and eliminates the need for physical cash.

Decentralization: Unlike traditional currencies controlled by central banks or governments, cryptocurrencies operate on decentralized networks. This means that no single authority has control over their issuance or transactions.Now, let’s move on to Module 1.2:
