It is a project credited to three Stanford University PHDs namely: Dr Nicolas Kokkalls (head of technology), Dr Chengdiao Fan (Head of product) and Vincent McPhillip (head of community).
The company only offers a service, but no product. After downloading the Pi Network app, you need to confirm that you are a human by pressing a lightning symbol on the app at 24 hours intervals. This will initiate the mining process at a predetermined rate on your mobile device (currently 0.12pi/hr) without draining your phone battery. You are free to exit the app after that action without discontinuing the mining process.
It is an FREE App. Free to download either from google play or apple store. You may search pi, pinetwork,or minepi.
Members can join only on invitation from other members. You can accelerate your mining rate by inviting other members to join using your code. You are welcome to use mine to join if you decide to or if this review add any value to you (otdto).
After three successful mining cycles of 24 hours each, you qualify to become a contributor and you can form a security circle of 3 to 5 trusted members. This will accelerate your mining rate as well.
The mining rate has been halve for any multiple of 10 members that the network achieved. The project started in March 2019 at a rate of 3.1 Pi/hr and in November 2019 the network reached 1 million members and the current rate was 0.20 pi/hr.
