Pi Network is a blockchain project that allows users to mine cryptocurrency through a mobile app. It was started in 2019 by Stanford graduates and aims to make crypto accessible to everyday people without the need for specialized hardware or technical knowledge. Unlike Bitcoin, which requires expensive mining equipment, Pi can be earned by verifying presence on a phone app daily. Users can mine Pi by simply downloading the Pi Network app and tapping a button to confirm they are not a bot. The project aims to create a digital currency system that anyone can join.
