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.
