Are you curious about cryptocurrency? It's a digital or virtual form of currency that uses cryptography for security. Let's dive deeper into this fascinating world of cryptocurrency and understand how it works.

What is cryptocurrency?

Cryptocurrency is a type of digital or virtual currency that uses cryptography for secure financial transactions, control the creation of additional units, and verify the transfer of assets. Unlike traditional currencies issued by governments, cryptocurrencies are decentralized and operate on a technology called blockchain.

How does cryptocurrency work?

Cryptocurrencies work on a technology called blockchain, which is a decentralized and distributed ledger. Blockchain records all the transactions made with a particular cryptocurrency and ensures the transparency and security of the system. Each transaction is verified by a network of computers called miners, and once validated, it gets added to the blockchain.These transactions are stored in blocks, and as new transactions occur, they are added to the chain in a time-stamped manner. The blockchain ensures that transactions cannot be tampered with or reversed, providing security for the entire system.

Popular cryptocurrencies

  • Bitcoin: The first cryptocurrency created in 2009 by an anonymous person known as Satoshi Nakamoto. It remains the most valuable and widely recognized cryptocurrency today.
  • Ethereum: Launched in 2015, Ethereum is not just a cryptocurrency but also a platform for creating smart contracts and decentralized applications.
  • Ripple: Focused on enabling fast and low-cost international money transfers, Ripple aims to revolutionize the traditional banking system.
