⚙️ How Does Bitcoin Work?

1. Blockchain Technology

Bitcoin transactions are stored on a blockchain, which is like a digital ledger. Every time someone sends or receives Bitcoin, a record of that transaction is added to a "block". These blocks are linked together to form a chain – the blockchain.

2. Bitcoin Mining

Mining is the process of verifying transactions and adding them to the blockchain. Miners use powerful computers to solve complex mathematical problems. The first miner to solve it gets a reward in Bitcoin – this is how new Bitcoins are created.

3. Bitcoin Wallets
