📖 Introduction
What is Cryptocurrency?
A cryptocurrency is a decentralised digital or virtual currency. It employs cryptography to ensure the security of its transactions and to control the creation of new units.
Unlike traditional currencies issued by central banks, cryptocurrencies operate independently of central authorities.
Examples of Cryptocurrencies:
- Bitcoin (BTC)
- Ethereum (ETH)
- Ripple (XRP)
- Litecoin (LTC)
How Cryptocurrency Transactions Work: The Blockchain
All cryptocurrency transactions are recorded on a public digital ledger known as the blockchain. This ledger is an immutable and transparent record of every transaction ever made.
The blockchain is maintained by a vast, decentralised network of computers spread globally. These computers work together to verify and add new transactions to the chain.
The combination of decentralisation and advanced cryptographic techniques makes it extremely difficult for any single entity to manipulate the currency or alter transactions once they are recorded on the blockchain.
Digital Wallets: Your Gateway to Crypto
To participate in cryptocurrency transactions, individuals or businesses need a digital wallet. This is a software application designed to securely store a user's public and private keys.
These keys are fundamental for sending and receiving cryptocurrency. They are also essential for verifying transactions on the blockchain, ensuring only the rightful owner can initiate transfers.
Cryptocurrency Mining: Creating New Units
New cryptocurrencies are typically generated through a process called mining. This involves using significant computational power to solve complex mathematical problems.
The mining process serves a dual purpose: it validates and records new transactions onto the blockchain, and in return, the successful 'miner' is rewarded with a certain amount of cryptocurrency.
UPSC Insight: Understanding decentralisation, blockchain technology, and cryptography is crucial. These concepts have broader implications for digital governance and cybersecurity, often appearing in GS Paper III.
