All bitcoin transactions are written down on a massive public ledger, known as Block Chain. Now, when you transfer bitcoin from your wallet to another person’s wallet, you write this transaction in block chain.

Now, all the miners in bitcoin network know how much bitcoins are there in your wallet, infact in every wallet. In simple words, every miner know the number of bitcoins in each wallet, but, they don’know who owns which wallet. Because, bitcoin has no identity of any wallet.

Now, if everyone can see amount of bitcoins in each wallet, then what’s stopping them from transferring bitcoins from your wallet to theirs?

It’s cryptography technology which is stopping them from transferring bitcoins from your wallet to theirs. When a bitcoin wallet is generated for you, it has two parts. One is public part, an address of your wallet, to share with other miners so that they know where to send you bitcoins. And, the other part is a private key. To approve any transaction from your wallet, you need this private key.

For any successful transaction, you need to send a message from your wallet containing your wallet’s address, receiver’s wallet address, amount and digital signature. This digital signature is unique for every transaction; and, is generates by the combination of transaction message and the private key. Once your digital signature is verified, your transaction finally completes.
