Information and Technology: Cryptocurrency

What is it?

  • Cryptocurrency, also known as crypto, is a type of digital currency that operates through a computer network without the need for a central authority like a government or bank to oversee it.
  • It works as a decentralized system, verifying transactions and ensuring that the parties involved have the funds they claim to possess.

Examples of Cryptocurrency

  1. Bitcoin (BTC)
    • It is the first and most well-known cryptocurrency, created in 2009.
    • Bitcoin was invented by an unknown person or group of people using the name Satoshi Nakamoto and was released as open-source software in 2009. It is considered the first decentralized cryptocurrency.
    • Bitcoin has no single administrator, and the currency can be sent electronically from user to user on the peer-to-peer Bitcoin network without the need for intermediaries.
    • Transactions are verified by network nodes through cryptography and recorded in a publicly distributed ledger called a blockchain.
  2. Ethereum (ETH)
    • Ethereum (ETH) is a decentralised, open-source blockchain platform that enables the creation of smart contracts and decentralised applications (dApps).
    • It uses its own cryptocurrency, Ether, as a means of payment for transaction fees and services on the Ethereum network.
    • It also has a built-in programming language that enables developers to create and deploy their own decentralized applications on the Ethereum network.
  3. Litecoin (LTC)
    • Litecoin (LTC) is a peer-to-peer cryptocurrency and open-source software project.
    • It is inspired by and nearly identical to Bitcoin (BTC) but with faster transaction confirmation times and a different hashing algorithm.
    • It is designed to process small transactions faster and more efficiently than Bitcoin.
  4. Ripple (XRP)
    • Ripple (XRP) is a digital asset and cryptocurrency that is designed to facilitate fast and inexpensive international money transfers.
    • It is built on the Ripple Protocol, a decentralized open-source protocol for facilitating cross-border payments.
    • Ripple can be used to transfer any currency, including USD, EUR, and Bitcoin, and it can also be traded on digital currency exchanges.
  5. Bitcoin Cash (BCH)
    • Bitcoin Cash (BCH) is a cryptocurrency that was created as a result of a hard fork from Bitcoin in 2017.
    • It has a larger block size limit (8MB) compared to Bitcoin (1MB), allowing for faster and cheaper transactions.
    • It is considered by some to be a “purer” version of Bitcoin, as it adheres more closely to the original vision of Bitcoin as a peer-to-peer electronic cash system.

Advantages of Cryptocurrency

Disadvantages of Cryptocurrency
