Cryptocurrencies are digital or virtual currencies that use blockchain technology to enable secure and decentralized transactions
A blockchain consists of a series of blocks, which are batches of transactions. Each block is added to the blockchain in a linear, chronological order, and contains a cryptographic hash of the previous block, a timestamp, and transaction data. This creates a permanent, unchangeable record of all transactions on the network.
Cryptocurrencies are digital or virtual currencies that use blockchain technology to enable secure, decentralized transactions. They are based on a network of computers, known as nodes, that verify and validate transactions using complex mathematical algorithms. Each cryptocurrency has its own blockchain, and the transaction data on the blockchain is used to create a digital ledger of all transactions on the network.
Cryptocurrencies are often used as a medium of exchange, and are traded on online exchanges. They are decentralized, meaning that they are not controlled by any central authority or government. Instead, they are underpinned by the blockchain technology, which allows for secure and transparent transactions.
