No longer a buzzword, but changing how we use and even think about money. What exactly are they, and how do they work?

Digital currencies, like Bitcoin and Ethereum, operate on sophisticated blockchain technology to give an efficient way to deal with transactions anywhere in the world, securely and with minimal processing time. The numbers of applications for cryptocurrencies continue to be impressive in this new world of finance.

This book breaks down the jargon of cryptocurrencies into simple and nontechnical terms, allowing you to feel comfortable exploring this revolutionary form of money.

What is Digital Currency?

• Definition 

• Digital currency is an electronic money that only exists digitally. It is stored online, transferred online, and totally transacted online; whereas cash or banknotes cannot be used in this aspect.

• Examples of Digital Currencies:

• Cryptocurrencies: Bitcoin (BTC), Ethereum (ETH), Litecoin (LTC).
• Central Bank Digital Currencies (CBDCs) are government-issued digital versions of traditional money.

Why It's Unique:

• No single central authority controls it-except for a government or bank.
• Transactions happen directly amongst the users, hence becoming decentralized.

A Brief History of Cryptocurrencies

1.  Bitcoin’s Birth:

• Created in 2009 by an anonymous person (or group) called Satoshi Nakamoto.

2.  The Evolution of Altcoins:

• Ethereum launched in 2015, introducing smart contracts and expanding crypto’s use cases.
• Over 10,000 cryptocurrencies now exist, each with unique features.

How Does Cryptocurrency Work?

1.  Blockchain Technology

• Think of it as an e-book. Each and every transaction is embedded in a block, and that block is then associated with several other blocks in a unbreakable chain.
• It is a technology that ensures all transactions are clear and exposes frauds.

2.  Decentralization

• The system of cryptocurrencies doesn't depend on the banks but on a network of computers called nodes.
• The peer-to-peer model excludes middlemen, making the transactions quicker and cheaper. 

3.  Encryption and Safety

• Through cryptographic keys, transactions are encrypted so funds and data may not be exposed.
• Private keys serve as passwords to open the digital wallet.
