The coming proof-of-stake network will make ETH miners obsolete. That doesn't mean they're going away. Ethereum, like Bitcoin, currently uses an energy-intensive process called “mining” to create and distribute new cryptocurrency. The thousands of people globally who help make that happen, known as miners, operate millions of dollars worth of machinery in a race to solve computational problems and earn ETH, the network’s native cryptocurrency. But at some point within the next year, Ethereum will undergo a major upgrade that will fundamentally change how the network operates and how new ETH is created. Ethereum mining will become a thing of the past.
