How Does Bitcoin Work?

Bitcoin operates on a peer-to-peer network, meaning that transactions are made directly between users without the need for an intermediary like a bank. Here's how the process works:

1. Wallets and Keys

To use Bitcoin, you'll need a digital wallet. This wallet contains a pair of cryptographic keys: a public key, which acts as your address on the Bitcoin network, and a private key, which allows you to sign transactions and access your funds. It's crucial to keep your private key secure because anyone with access to it can control your Bitcoin.

2. Transactions

When you send Bitcoin, your transaction is broadcast to the entire network. Each transaction contains information like the sender's and receiver's addresses, the amount of Bitcoin being transferred, and a digital signature created by the sender's private key.

3. Mining and Confirmation

Once your transaction is broadcast, it needs to be verified by the network. This is done by miners, who use powerful computers to solve complex mathematical puzzles. When a miner successfully solves the puzzle, your transaction is added to a block, which is then appended to the blockchain. This process is known as "mining," and it ensures that all transactions are legitimate and that the same Bitcoin can't be spent twice.

4. Blockchain

The blockchain is a public ledger that records all Bitcoin transactions. It is maintained by a distributed network of computers, each of which has a copy of the entire blockchain. Every time a new block is added, the blockchain is updated, and all participants in the network can see the new transaction.

5. Finality

Once a transaction is added to the blockchain, it is considered final. It cannot be reversed or altered, which gives Bitcoin its security and trustworthiness. The process is transparent and decentralized, meaning no single entity controls the Bitcoin network.
