Crypto, short for cryptocurrency, is a type of digital or virtual currency that uses cryptography to secure transactions and control the creation of new units. Cryptocurrencies operate on decentralised networks based on blockchain technology, enabling peer-to-peer transactions without the need for intermediaries like banks or governments.

Key Features of Cryptocurrencies:

  1. Decentralisation: Most cryptocurrencies are decentralised and operate on distributed ledgers (blockchains) maintained by a global network of nodes.
  2. Blockchain Technology: A blockchain is a secure and transparent ledger that records all cryptocurrency transactions.
  3. Cryptography: Cryptocurrencies use advanced cryptographic techniques to secure transactions, control the supply of coins, and ensure the integrity of the network.
  4. Digital Nature: Cryptocurrencies exist only in digital form and are accessed using wallets, which store private and public keys.

Examples of Cryptocurrencies:

  • Bitcoin (BTC): The first and most popular cryptocurrency, often considered digital gold.
  • Ethereum (ETH): A blockchain that supports smart contracts and decentralised applications (dApps).
  • Stablecoins: Cryptocurrencies like USDT or USDC that are pegged to a stable asset (e.g., the US Dollar) to reduce price volatility.
  • Altcoins: Other cryptocurrencies like Litecoin (LTC), Cardano (ADA), and Polkadot (DOT).

How Cryptocurrencies Work:

  1. Transactions: Users transfer funds by signing transactions with their private keys. These transactions are verified and added to the blockchain by network participants.
  2. Mining/Staking: Cryptocurrencies use mechanisms like Proof of Work (PoW) or Proof of Stake (PoS) to validate transactions and secure the network.
  3. Wallets: Digital wallets store private keys that give users access to their cryptocurrencies.

Uses of Cryptocurrencies:

  • Digital Payments: Facilitates quick, low-cost cross-border transactions.
  • Investments: Many people buy cryptocurrencies as speculative assets due to their potential for price growth.
  • Decentralised Finance (DeFi): Cryptocurrencies power financial applications like lending, borrowing, and trading without traditional intermediaries.
  • Non-Fungible Tokens (NFTs): Digital assets representing ownership of unique items, like art or music, built on blockchain networks.

Cryptocurrencies represent a significant innovation in the way value can be transferred, stored, and accessed globally.
