Cryptocurrency Mining is the process by which new coins are created and transactions are validated on the blockchain. It is fundamental to the security and functioning of networks such as Bitcoin.
What is Mining?
Mining is the process of using computational power to:
- Validate transactions on the network
- Add new blocks to the blockchain
- Maintain the security of the network
- Create new coins as a reward
How Does it Work?
Proof of Work (PoW)
Miners compete to solve complex mathematical problems:
- Transaction Collection: Miners group pending transactions
- Puzzle Resolution: They try to find a number (nonce) that generates a valid hash
- Validation: The first to solve adds the block to the blockchain
- Reward: Receives new coins + transaction fees
Necessary Equipment
Hardware
- CPU: Obsolete for Bitcoin
- GPU: Used for some altcoins
- ASIC: Specialized equipment for Bitcoin
Software
- Mining client
- Digital wallet
- Mining pool (optional)
Costs Involved
- Equipment: Hundreds to thousands of dollars
- Electricity: Main operational cost
- Cooling: Equipment generates a lot of heat
- Maintenance: Parts and repairs
