What is Bitcoin?
Bitcoin is a decentralized digital currency that uses cryptography for secure financial transactions. It is not controlled by any government or financial institution and allows for anonymous transactions.
Unlike services like Venmo and PayPal, which rely on the traditional financial system for permission to transfer money and on existing debit/credit accounts, bitcoin is decentralized: any two people, anywhere in the world, can send bitcoin to each other without the involvement of a bank, government, or other institution.
Every transaction involving Bitcoin is tracked on the blockchain, which is similar to a bank’s ledger, or a log of customers’ funds going in and out of the bank. In simple terms, it’s a record of every transaction ever made using bitcoin.
Unlike a bank’s ledger, the Bitcoin blockchain is distributed across the entire network. No company, country, or third party is in control of it; and anyone can become part of that network.
There will only ever be 21 million bitcoin. This is digital money that cannot be inflated or manipulated in any way.
It isn’t necessary to buy an entire bitcoin: you can buy just a fraction of one if that’s all you want or need.
Bitcoins are created through a process called "mining," which involves solving complex mathematical problems with specialized computer hardware. When a problem is solved, a new block is added to the chain of blocks that make up the Bitcoin blockchain, and the miner is rewarded with a certain number of Bitcoins.
Users can send and receive Bitcoins through the use of Bitcoin addresses, which are unique strings of letters and numbers that function like bank account numbers. Transactions are recorded on the blockchain, which is a public ledger that is distributed across the network. This makes it difficult for anyone to alter the record of transactions.
How Bitcoin works?
When someone wants to make a transaction with Bitcoin, they send a message to the network with the details of the transaction. This message is broadcast to all the computers on the network, and each computer verifies the transaction using the rules of the Bitcoin system.
Once the transaction has been verified, it is added to the blockchain, which is a record of all the transactions that have ever occurred on the network. The transaction is then considered to be complete.
The process of verifying transactions and adding them to the blockchain is known as "mining." Miners use special software to solve complex mathematical problems, and when they solve a problem, they are rewarded with a certain number of Bitcoins. This process helps to secure the network and ensure that the record of transactions is accurate.
How Bitcoin earns?
New Bitcoins are created as part of the Bitcoin mining process, in which they are offered as a lucrative reward to people who operate computer systems that help to validate transactions. Bitcoin miners — also known as "nodes" — are the owners of high-speed computers which independently confirm each transaction, and add a completed "block" of transactions to the ever-growing "chain." The resulting blockchain is a complete, public and permanent record of every Bitcoin transaction.
Miners are then paid in Bitcoin for their efforts, which incentivizes the decentralized network to independently verify each transaction. This independent network of miners also decreases the chance for fraud or false information to be recorded, as the majority of miners need to confirm the authenticity of each block of data before it's added to the blockchain in a process known as proof-of-work
