Pi coins are based on Star Identification Protocol (SCP) and Federal Byzantine Protocol (FBA) to build an identification mechanism, which is characterized by being lighter and not consuming resources. It will not consume electricity and traffic, and smartphones are also very common, so lowering the threshold will greatly increase the number of participants. Pi has been launched simultaneously in more than 100 countries around the world, and chat rooms in 43 languages have been opened in the in-app community. You can mine for free with your mobile phone, and you only need to open it once every 24 hours to collect the income. Every time the number of people increases by 10 times, the output will be halved, and mining will stop after100000.
