$BTC How does Bitcoin work? The Bitcoin network shares a ledger called the “blockchain”. This ledger contains all financial transactions that have ever been processed on the network, allowing a user’s computer to verify the validity of each transaction. The authenticity of each transaction is protected by a digital signature, linked to the sending address, allowing all users to have full control over sending this digital currency from their Bitcoin addresses. In addition, anyone, using the right hardware and computing power, can process these transactions and receive rewards for doing so. This is called “mining”.
