Cryptocurrency mining is the process of validating blockchain transactions and adding new blocks by solving computationally intensive mathematical puzzles. Miners are rewarded with newly created cryptocurrency. Bitcoin mining has evolved from home CPUs to industrial ASIC farms consuming gigawatts of power.
2009

Transaction validation, network security, new coin issuance
💡 Did You Know
In 2010, a developer mined 50 Bitcoin using a laptop CPU. Today, that same computing power would take billions of years to mine a single block.
⚠ Controversies & Red Flags
Bitcoin mining's energy consumption equals that of some medium-sized countries. Its environmental impact is a persistent criticism and regulatory concern.
