How is bitcoin mined?
Bitcoin mining is the process of verifying transactions and adding them to the blockchain using powerful computers.
It relies on a consensus mechanism called
Proof of Work
, which requires solving complex mathematical problems.
Miners use specialized hardware called
ASICs (Application-Specific Integrated Circuits)
for efficient mining.
Miners compete to solve a cryptographic hash function. The first to succeed adds the next block to the blockchain.
The winning miner earns a
block reward
in Bitcoin plus transaction fees from the block.
Bitcoin rewards halve approximately every 4 years, reducing the number of new bitcoins entering circulation.
Mining consumes a large amount of electricity—this is a major factor in mining costs and environmental concerns.
Many miners join
mining pools
to combine computing power and increase chances of earning rewards.
Bitcoin mining can be profitable but requires significant investment in hardware, electricity, and technical know-how.
