Cryptocurrencies are digital or virtual tokens that use cryptography to secure their transactions and to control the creation of new units. Cryptocurrencies are decentralized, meaning they are not subject to government or financial institution control. Blockchain is a distributed database that maintains a continuously growing list of records called blocks. Each block contains a timestamp and a link to a previous block. Bitcoin, the first and most well-known cryptocurrency, uses a blockchain to record transactions. Cryptocurrencies are often traded on decentralized exchanges that are built on blockchain technology. This allows for a peer-to-peer exchange of tokens without the need for a central authority. Blockchain and cryptocurrencies have the potential to disrupt a number of industries. The technology can be used to create a more secure and efficient financial system. It can also be used to create new types of decentralized applications.
