Bitcoin mining is the process that keeps the Bitcoin network running and secure. It’s how new bitcoins are created and how transactions get verified.

• Transactions are broadcast
  When people send Bitcoin, those transactions are grouped into a “block.”
• Miners compete to solve a puzzle
  Computers (called miners) race to solve a complex math problem using hashing (a cryptographic function).
• Proof of Work
  The first miner to solve it proves they did the work (called Proof of Work) and gets to add the block to the blockchain.
• Reward
  That miner earns:
  • Newly created Bitcoin (block reward)
  • Transaction fees from users
