How Does Cryptocurrency Work?
Cryptocurrencies use decentralized ledger technology called the blockchain to record transactions and verify their validity. A blockchain is a public ledger of all cryptocurrency transactions that have ever been executed.
Each block in the chain contains a number of transactions and is verified by a network of computers before being added to the chain.
Each cryptocurrency has its own blockchain, and each transaction is broadcast to the network of computers for verification. Once the transaction is verified, it is added to the blockchain and cannot be altered or deleted.
The blockchain also ensures the integrity and security of the currency, making it virtually impossible to counterfeit or double-spend.
