🔍 What is Cryptocurrency?
Cryptocurrency is a type of digital or virtual currency that uses cryptography for secure financial transactions. Unlike traditional currencies issued by governments (like USD or EUR), cryptocurrencies are decentralized and operate on blockchain technology.
Some of the most well-known cryptocurrencies include:
-
Bitcoin (BTC)
-
Ethereum (ETH)
-
Ripple (XRP)
-
Solana (SOL)
🧠 How Does Cryptocurrency Work?
At its core, cryptocurrency relies on blockchain — a distributed digital ledger that records every transaction across a network of computers.
Here’s how it works step-by-step:
1. Blockchain Technology
Each transaction is grouped into a “block.” Once verified by the network, it’s added to the chain — hence the name blockchain. This ensures transparency and prevents tampering.
2. Cryptography
Advanced encryption techniques secure each transaction, making it nearly impossible to counterfeit or double-spend.
3. Mining or Staking
Depending on the crypto, new coins are created through:
-
Mining (Proof of Work, like Bitcoin)
-
Staking (Proof of Stake, like Ethereum 2.0)
4. Digital Wallets
Cryptocurrencies are stored in crypto wallets, which can be:
-
Hot wallets (online, accessible via internet)
-
Cold wallets (offline, more secure)
5. Decentralization
No central authority (like a bank or government) controls cryptocurrency. Instead, the network of users verifies and processes all transactions. Bright IT Institute
