Cryptocurrency miners are individuals or groups who use powerful computers to solve complex mathematical problems that validate transactions on a blockchain. This process is essential for maintaining the security and integrity of the cryptocurrency network. When miners successfully solve these problems, they add a new block of transactions to the blockchain and are rewarded with newly created cryptocurrency. Mining requires significant computational power and energy, leading to concerns about its environmental impact. Miners often join mining pools to combine their resources and increase their chances of earning rewards. Overall, cryptocurrency mining plays a crucial role in the functioning of various digital currencies.
