Cryptocurrencies are digital or virtual currencies that use cryptography to secure transactions. Unlike traditional currencies like the dollar or euro, cryptocurrencies aren't controlled by any central authority like a central bank or government. This makes them decentralized and potentially more resistant to censorship and manipulation.
How Do Cryptocurrencies Work?
Cryptocurrencies operate on a technology called blockchain. A blockchain is a public, distributed ledger containing all transactions ever made on the network. This ledger is maintained by a network of computers called nodes, which work together to validate and record new transactions.
To send cryptocurrency to someone else, you need a digital wallet containing your cryptographic keys. These keys allow you to sign transactions and access your funds. When you send cryptocurrency, the transaction is broadcast to the network, where nodes verify its legitimacy. Once verified, the transaction is added to the blockchain and considered complete.
