What Is Cryptocurrency?
Cryptocurrency is a form of digital or virtual currency secured by cryptography. Unlike traditional currencies controlled by governments and central banks, cryptocurrencies operate on decentralized networks based on blockchain technology.
Key Characteristics of Cryptocurrencies:
-
Decentralization: No central authority controls the system.
-
Transparency: All transactions are recorded publicly.
-
Security: Strong encryption ensures safe transactions.
-
Limited Supply: Most coins have a capped supply, increasing scarcity and value.
How Does Blockchain Work?
The backbone of cryptocurrency is blockchain — a distributed digital ledger that records all transactions across a network of computers. Each "block" contains a set of transactions, and once verified, it is added to the "chain," making the data immutable and secure.
