What is Bitcoin?
Bitcoin is a digital file or ledger that contains names and balances. People exchange money by changing this file. Everyone has an account. When they buy something and pay by Bitcoin; their balance of Bitcoin go down. (Pretty much like a bank account).
When you sell items through internet and receive Bitcoin instead of it. Your balance of Bitcoin in your account goes up. (Like you have deposited more money into your bank account) but here; there is no money or gold transferred between the seller and buyer.
The seller trusts the system and sells items and is satisfied with the increase of Bitcoin in his/her account. The seller will be able to change the Bitcoin to any other currency and turn them into money.
Is there a bank or a centralized system to check and maintain Bitcoins?
The answer is NO. There is no bank or centralized system that controls Bitcoin. Every user maintains a copy of ledger. So; everyone can see everyone else’s balance.
Note: The ledger only contains the account numbers. No name is shown in the ledger.
How are the ledgers sync on all computers in the world?
When a user starts sending a money; a broadcast is being sent to everyone and informs them about “the Bitcoin Sender, receiver and amount of Bitcoin”. Then all the ledgers are being updated.
How to ascertain that no one can spend other’s money?
When a new Bitcoin account is created, a private key (Cryptography key) is being linked to that account number. This private key is being used to create a signature on the transactions.
A similar method then checks the signature and confirms that the signature was created by the account holder.
Each signature is unique and cannot be used in other transactions (Unlike the handwritten signature)
