|What is Bitcoin mining?|
|Bitcoin Mining is the process of adding transaction records to the public account of past transactions by Bitcoin (and a mining rig is a colloquial metaphor for a single computer system that performs the necessary mining computations). This past transaction ledger is called the block chain because it is a chain of blocks. The block chain is used to confirm transactions that have occurred to the rest of the network. Bitcoin nodes use the block chain to differentiate legitimate Bitcoin transactions from attempts to re-spend coins already spent elsewhere.
