Chapter 1: What Is Cryptocurrency?
Defining Cryptocurrency Cryptocurrency is a digital or virtual form of currency that uses cryptography for security. Unlike traditional currencies issued by governments (known as fiat currencies), cryptocurrencies are decentralized and typically rely on blockchain technology to record and validate transactions.
The Birth of Bitcoin Bitcoin, created by an anonymous individual or group using the pseudonym Satoshi Nakamoto, marked the birth of cryptocurrencies in 2009. It was introduced as a decentralized, peer-to-peer electronic cash system, designed to eliminate the need for intermediaries like banks in financial transactions.
Key Characteristics of Cryptocurrency
- Decentralization: Cryptocurrencies operate on a decentralized network of computers, making them resistant to central control.
- Digital Nature: Cryptocurrencies exist only in digital form, with no physical counterparts like coins or bills.
- Security: Strong cryptographic techniques ensure the security of transactions and the creation of new units.
- Transparency: Blockchain technology provides a public ledger of all transactions, enhancing transparency.
- Anonymity: While transactions are recorded on a public ledger, users’ identities are often pseudonymous.
- Limited Supply: Many cryptocurrencies have a capped supply, such as Bitcoin’s 21 million coins.
