Frequently Asked Questions
What is mining in blockchain?
Mining is the process of validating transactions and adding them to the blockchain. Miners compete to solve a cryptographic puzzle by finding a nonce that produces a hash below the difficulty target.
What is the difficulty target?
The difficulty target is a threshold that the block hash must be below for the block to be valid. A lower target means more leading zeros are required, making it harder to find a valid hash.
Why does mining consume so much energy?
Miners must perform billions of hash calculations per second to have a chance of finding a valid nonce. This computational work is intentional — it makes the network secure but energy-intensive.
What happens when a miner finds a valid block?
The miner broadcasts the block to the network. Other nodes verify it, add it to their copy of the blockchain, and the miner receives the block reward plus transaction fees.
