I think the fastest way to connect Africa to the internet is to use a decentralized Satellite internet sharing system which incentivizes operators with cryptocurrencies. E.g., if you set up a StarLink station or share internet via your own hardware and connectivity, you get paid based on who uses your networks.
I can see a combination using HiveCell and Helium plus StarLink or other satellite internet provider.
I’m going to give this a shot. Really all that needs to be done is outline the idea and connect some folks together. Not sure if it will work, timing is a big component.
