The full name of Pi Coin is Pi Network, which is a virtual currency network similar to Bitcoin and Ethereum, developed by a doctoral team at Stanford University. Pi aims to build a blockchain network that everyone can participate in, because Bitcoin has deviated from its original purpose and has become a speculative tool for capital, and the mining of Bitcoin, Ethereum and many digital currencies is excessive due to the high threshold. Concentration makes most users unable to participate. Pi pioneered the use of mobile phone applications for mining, which greatly reduces the threshold for mining virtual coins, so that Pi has extremely high ease of use and broad consensus.
