What Is Cryptocurrency?
At its core, a cryptocurrency is a digital or virtual currency secured by cryptography. Unlike traditional fiat currencies such as the US dollar or euro, cryptocurrencies are decentralized and typically based on blockchain technology—a distributed ledger enforced by a network of computers (called nodes).
Key Characteristics of Cryptocurrency
Decentralization: No central bank or government controls the supply.
Transparency: All transactions are recorded on public ledgers.
Security: Advanced cryptographic methods ensure data integrity and ownership.
Limited Supply: Most cryptocurrencies have a capped supply, making them deflationary.
Popular examples include Bitcoin (BTC), Ethereum (ETH), Solana (SOL), and Ripple (XRP).
How Does Cryptocurrency Work?
Cryptocurrencies operate through blockchain networks. A blockchain is a digital chain of blocks that contain transaction data. Once verified, the data is stored permanently and cannot be altered.
The Process:
A transaction is initiated.
It’s verified by network nodes.
Once validated, it’s added to the blockchain.
The user’s wallet reflects the change.
Each wallet is secured by a private key and a public address—a powerful combination ensuring that only the rightful owner can access or send their funds.
