Understanding Cryptocurrency: A Beginner’s Guide

Cryptocurrency is a digital form of money that operates without a central authority such as a bank or government. Instead of relying on intermediaries, cryptocurrencies use blockchain technology to ensure transparency, security, and trust between users.

What Is Blockchain?

Blockchain is a decentralized digital ledger that records all transactions across a network of computers. Each transaction is stored in a block, and these blocks are linked together in chronological order. Once recorded, data on the blockchain cannot be easily altered, making it highly secure.

How Cryptocurrency Works

Cryptocurrencies use cryptographic techniques to secure transactions. When a user sends crypto, the transaction is verified by network participants (called miners or validators) and then added to the blockchain. This process removes the need for third-party verification.
