What is Bitcoin?
Bitcoin is a type of digital currency that you can use to buy things online, or you can trade it for regular money. It’s different from regular money because it’s not controlled by a government or a bank. Instead, it’s run by a network of computers all over the world that work together to make sure everything is fair and accurate.
When someone wants to send some bitcoin to someone else, they broadcast a message to the network with the details of the transaction, like how much bitcoin is being sent and who it’s being sent to. The computers in the network then work together to make sure that the person sending the bitcoin actually has it and that it’s not being spent twice.
Once the computers in the network approve the transaction, it gets added to a big public list of all the transactions that have ever happened with bitcoin, called the blockchain. And that’s how the bitcoin gets moved from one person to another.
And the special thing about bitcoin is that it is created through a process called mining, in which powerful computers use complex algorithms to solve complex mathematical puzzles to validate the transactions on the network, and for each block of transactions they validate, they get rewarded with a certain amount of bitcoins. The reward they get comes from the small fees that are paid when a bitcoin transaction is sent.
