Cryptocurrency represents a decentralized digital asset designed to work as a medium of exchange using cryptographic methods to secure transactions. Unlike traditional currencies issued by governments, cryptocurrencies operate on blockchain technology, ensuring transparency, security, and immutability of financial transactions.

The key characteristics of cryptocurrencies include:

  • Decentralization: No central authority governs the network.
  • Transparency: All transactions are publicly recorded on the blockchain.
  • Anonymity: Users can transact without revealing their identities.

"Blockchain technology ensures that every transaction is verified, transparent, and immutable, creating a new era of trust in digital finance."

Here’s a comparison between a traditional currency and cryptocurrency:
