Cryptocurrencies are digital or virtual currencies that use encryption techniques to secure and verify transactions. They are decentralized, meaning they are not controlled by any government or institution, and are created through a process called mining. The most well-known cryptocurrency is Bitcoin, which was created in 2009, but there are now thousands of different cryptocurrencies in existence.
Bitcoin, the first and most widely used cryptocurrency, is based on a decentralized ledger technology called blockchain. Transactions made with Bitcoin are recorded on a public ledger, and the integrity of the transaction is maintained through complex mathematical algorithms. Bitcoin can be used to purchase goods and services, and can also be traded on various online platforms.
Ethereum is another widely used cryptocurrency. It was created in 2015 and is based on a blockchain platform that allows for the creation of decentralized applications, or “smart contracts.” These contracts are self-executing and can be used for a wide range of purposes, from financial transactions to supply chain management.
Litecoin, created in 2011, is often referred to as the “silver to Bitcoin’s gold.” It is based on a similar blockchain technology, but is designed to be faster and more efficient than Bitcoin. It is also designed to be more accessible to a wider range of users, making it more suitable for small transactions.
