Introduction to Cryptocurrency
Cryptocurrency, often referred to as digital currency or crypto, is a decentralized form of money powered by blockchain technology. Unlike traditional currencies, cryptocurrencies operate without central authorities like banks or governments, offering transparency, security, and global accessibility.
Key Features of Cryptocurrency
- Decentralization: No single entity controls the network.
- Security: Cryptographic techniques ensure secure transactions.
- Transparency: All transactions are recorded on a public ledger (blockchain).
- Global Reach: Enables cross-border transactions without intermediaries.
How Cryptocurrency Works
Cryptocurrencies rely on blockchain technology, a distributed ledger that records all transactions across a network of computers. Here’s a simplified breakdown:
- Transaction Initiation: A user sends cryptocurrency to another user.
- Verification: Network nodes (miners/validators) confirm the transaction’s legitimacy.
- Block Creation: Verified transactions are grouped into a block.
- Chain Addition: The block is added to the existing blockchain, making the transaction immutable.
