What is Cryptocurrency?

Cryptocurrency is a type of digital asset designed to work as a medium of exchange. It uses encryption techniques to secure transactions and control the creation of new units.

How Does it Work?

Cryptocurrency operates using a technology called blockchain.

Blockchain Explained

  • A blockchain is a distributed ledger that records all transactions.
  • Each block contains transaction data.
  • Blocks are linked together in a chain.
  • Once data is added, it cannot be changed.

For example, when you send Bitcoin:

  • Transaction is broadcast to the network
  • Verified by nodes
  • Added to blockchain
  • Completed securely
