WhatвЂ™ll happen? This transaction also goes in the current block on the blockchain. The very next day, ABC tries to send the same bitcoin to another person.

This transaction gets stored in a block on the blockchain. LetвЂ™s see what will happen (through real life example) if one tries sending the same bitcoin twice. Also, you must remember that you cannot spend a bitcoin twice since all blocks are connected. However, your transaction will have a private key. Each transaction has a public key written on it. In the bitcoin transaction process, transactions are stored in blocks that are linked to each other in series, thus making a blockchain. The private key helps access your bitcoin wallet and must be kept a secret so that your bitcoin remains safe. Anyone can use your public key to send money, while your private key must remain confidential as it is your identity. To create this wallet, you get public and privateВ keys which are a set of numbers and letters like username and password. To store your bitcoin, you need a bitcoin wallet. These computers then store your message on the database also called the ledger. This message is then broadcasted to all computers in the network. You must first digitally sign a message that says, вЂњI am sending 70 bitcoins to ABCвЂќ. Say for instance, you need to send bitcoin to someone. In bitcoin terminology, this shared database is called distributed ledger that can be accessed using the blockchain. We need to record transactions in a database, essentially an excel sheet. BitcoinвЂ™s supply is limited, and it is produced at a fixed rate, which decreases over time. The higher the demand, the higher the price. You can also create bitcoin by using your computer.Д®ver wondered how bitcoin mining software works?Д«itcoin uses this technique of cryptographyВ to convert transaction data using blockchain.Д«itcoin works on the supply and demand concept which emphasises that something has more value if it is limited.

You can simply buy bitcoins using real currency, and then buy things with bitcoins. This decentralized digital currency is a valuable one in the list of cryptocurrencies.
