Miners compete to solve a cryptographic puzzle; the winner adds the next block and earns newly issued coins plus fees. Mining is energy-intensive and increasingly industrial.
Proof-of-Work vs Proof-of-Stake: How Each One Secures a Chain
Key takeaways
- Mining uses computing power to validate transactions and add new blocks on proof-of-work networks such as Bitcoin.
- Miners compete to solve a cryptographic puzzle, and the winner is rewarded with newly issued coins plus transaction fees.
- Mining can consume significant electricity and hardware, so profitability depends heavily on energy costs and competition.
Mining — frequently asked questions
Can I still mine Bitcoin on my home computer?
In practice no; Bitcoin mining now needs specialised hardware and cheap power, which makes ordinary PCs uncompetitive.
What is the difference between mining and staking?
Mining secures proof-of-work chains using computing power, while staking secures proof-of-stake chains by locking up tokens.
