Mining is the process of using computational power to solve complex mathematical puzzles, validate transactions, and add new blocks to a proof-of-work blockchain. Miners are rewarded with newly minted cryptocurrency.
Mining components include mining hardware (ASICs, GPUs), mining software, electricity, cooling systems, and mining pool membership.
Mining profitability factors: Cryptocurrency price, block reward, network difficulty, electricity costs, and hardware efficiency.
Environmental concerns: High energy consumption of PoW mining, shift toward renewable energy sources, and transition to Proof of Stake (Ethereum Merge) as an alternative.
