What is Cryptocurrency?

Cryptocurrency is a type of digital or virtual currency that uses cryptography for security. Unlike traditional currencies such as the dollar or rupee, cryptocurrencies are not controlled by any central bank or government. This guide will help you understand what it is, how it works, and some of the most popular cryptocurrencies available today.

They exist only in digital form and are stored in digital wallets. Transactions are recorded on a public digital ledger called a blockchain.

• 100% digital
• Decentralized (not controlled by one authority)
• Secured by cryptography
• Stored in digital wallets

How Does Cryptocurrency Work?

Cryptocurrencies work using a technology called blockchain. A blockchain is a distributed ledger that records all transactions across a network of computers.

Step-by-Step Process:

• Transaction Initiation: A user sends cryptocurrency to another user.
• Verification: The transaction is verified by a network of computers (called nodes).
• Block Creation: The verified transaction is grouped into a block.
• Adding to Blockchain: The block is added to the existing blockchain.
• Completion: The transaction is complete and permanently recorded.

This system makes crypto secure, transparent, and difficult to tamper with.
