What is Bitcoin Mining?

Many of you peoples probably heard of Bitcoin mining but only few of you knows what it actually is.

Bitcoin Mining is a peer-to-peer computer process used to secure and verify bitcoin transactions—payments from one user to another on a decentralized network.

It involves adding bitcoin transaction data to Bitcoin's global public ledger of past transactions. The Each group of transactions is called a block.Blocks are secured by Bitcoin miners and build on top of each other forming a chain. This ledger of past transactions is called the blockchain. The blockchain serves to confirm transactions to the rest of the network as having taken place. Bitcoin nodes use the blockchain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
