The basics
Bitcoin mining is the process by which new bitcoins are created and transactions are verified and added to the blockchain. It’s done by powerful computers solving complex mathematical problems.
Why is mining important?
Mining secures the network, ensures that no one spends the same bitcoin twice (double-spending), and keeps the system decentralized. Miners are rewarded with new bitcoins and transaction fees for their work.
How it works
Miners group transactions into blocks. To add a block, they must find a valid hash – a number that meets certain conditions. This process is called proof of work and requires massive computing power.
