Cryptocurrency Ki Paribhasha: What Is Cryptocurrency?
Cryptocurrency, or डिजिटल मुद्रा, is a form of digital or virtual currency that uses cryptography for security. Unlike traditional currencies like the rupee or dollar, it operates on decentralized networks called blockchains. Bitcoin, created in 2009, was the first cryptocurrency, sparking a global revolution in finance and technology.
Key Features of Cryptocurrency
- Decentralization: No central authority (like banks or governments) controls it.
- Blockchain Technology: Transactions are recorded on a public, tamper-proof ledger.
- Cryptography: Advanced encryption ensures secure transactions.
- Limited Supply: Many cryptocurrencies, like Bitcoin, have a capped supply to prevent inflation.
- Pseudonymity: Users transact via wallet addresses, not personal details.
How Does Cryptocurrency Work?
Cryptocurrencies rely on blockchain technology. When a transaction occurs, it’s grouped into a block, verified by miners (or validators), and added to the blockchain. Miners solve complex puzzles to validate transactions, earning crypto rewards. Users store their assets in digital wallets with private keys for access.
Types of Cryptocurrencies
- Bitcoin (BTC): The pioneer, often called ‘digital gold.’
- Altcoins: Alternatives to Bitcoin, like Ethereum (ETH) and Litecoin (LTC).
- Stablecoins: Pegged to stable assets (e.g., Tether/USD).
- Utility Tokens: Provide access to blockchain services (e.g., Filecoin).
Benefits of Cryptocurrency
- Enables fast, low-cost cross-border transactions.
- Offers financial access to unbanked populations.
- Reduces fraud risk through blockchain transparency.
- Acts as a hedge against inflation in unstable economies.
Challenges of Cryptocurrency
- High price volatility.
- Regulatory uncertainty in many countries.
- Energy-intensive mining processes (e.g., Bitcoin).
- Potential misuse for illegal activities.
