Primary Knowledge About Cryptocurrency
1. What is Cryptocurrency?
Cryptocurrency is a type of digital or virtual currency secured by cryptography, making it nearly impossible to counterfeit or double-spend. It operates on decentralized networks based on blockchain technology, a distributed ledger enforced by a network of computers.
2. Key Features of Cryptocurrencies:
Decentralization: Operates independently of central banks or governments.
Transparency: Transactions are recorded on a public ledger, visible to anyone.
Security: Cryptographic techniques ensure the integrity of transactions.
Anonymity: Users can transact without revealing personal information.
Global Accessibility: Can be used anywhere with internet access.
3. Major Cryptocurrencies:
Bitcoin (BTC): The first and most popular cryptocurrency, introduced in 2009.
Ethereum (ETH): Known for its smart contracts and decentralized applications (dApps).
Altcoins: Other cryptocurrencies like Binance Coin (BNB), Ripple (XRP), and Cardano (ADA).
4. Blockchain Technology:
The backbone of cryptocurrencies, blockchain is a distributed ledger that records all transactions in blocks, linked in chronological order. It ensures security and transparency while preventing data manipulation.
5. Wallets:
Cryptocurrency wallets store private and public keys, allowing users to send and receive digital assets.
Hot Wallets: Connected to the internet (e.g., mobile, desktop wallets).
Cold Wallets: Offline storage (e.g., hardware wallets, paper wallets).
6. Mining and Consensus Mechanisms:
Proof of Work (PoW): Miners solve complex problems to validate transactions (e.g., Bitcoin).
Proof of Stake (PoS): Validators are chosen based on the number of coins they hold (e.g., Ethereum 2.0).
