What is Cryptocurrency?

Cryptocurrency is a digital or virtual form of currency that utilizes cryptography for secure and decentralized transactions. Unlike traditional fiat currencies issued by governments and central banks, cryptocurrencies operate on decentralized networks based on blockchain technology.

The key features of cryptocurrencies include:

1. Decentralization: Cryptocurrencies operate on decentralized networks of computers (nodes) spread across the globe. These networks are maintained by a community of participants, rather than a central authority, ensuring transparency, resilience, and censorship resistance.
2. Blockchain Technology: Most cryptocurrencies utilize blockchain technology, a distributed ledger that records all transactions in a secure and immutable manner. Each transaction is verified by network participants through consensus mechanisms, such as proof-of-work (PoW) or proof-of-stake (PoS), before being added to the blockchain.
3. Security: Cryptocurrencies leverage cryptographic techniques to secure transactions and control the creation of new units. Public-key cryptography enables users to generate pairs of cryptographic keys: a public key, which serves as their address and is visible to others, and a private key, which they use to sign transactions and prove ownership of their cryptocurrency.
4. Anonymity and Pseudonymity: While transactions on the blockchain are transparent and traceable, cryptocurrency transactions typically do not require users to reveal their identities. Instead, users are identified by their cryptographic addresses, providing a level of anonymity and pseudonymity.
5. Limited Supply: Many cryptocurrencies have a limited supply, meaning there is a maximum number of coins or tokens that can ever be created. For example, Bitcoin has a capped supply of 21 million coins, which helps to prevent inflation and maintain scarcity.
6. Global Accessibility: Cryptocurrencies can be accessed and transacted with from anywhere in the world, as long as there is an internet connection. This accessibility makes cryptocurrencies particularly useful for cross-border transactions and financial inclusion in regions with limited access to traditional banking services.
