# Mining

Mining , for example, is no longer possible without special expensive equipment. In 2010–2015, even a home computer with a powerful video card was good for this, but now it requires industrial computing power.

The fact is that there can’t be more than 21 million bitcoins. Most of them have already been generated, and each new bitcoin requires more and more power.

What is blockchain and mining :

* When you send 1 ETH, the miner’s job is to check if you have enough funds, and if so, it lets you send the crypto to the recipient.
* **Why does he need to do that?**\
  He will get a reward from you in the form of a commission, and from the blockchain itself for completing the block.
* **Why can the miner be trusted?**\
  That’s what proof of honest work done is invented for. The yoke is called consensus.
