Geodnet. Simple system that is easy to understand and calculate rewards. They do have a little trick that differentiates them; the goal is to track satelites and rewards are based on the satelites you see, so every station that is setup correctly helps the network, even if no customer is using data from that station, because it helps advertise global map coverage. Also you cant game the system because you arr forced to install correctly in order to earn anything…cant see satelites? No rewards.
And of course they burn 80% of revenue as tokens, which is huge, and is really why the token price has survived this long. The other side of this coin that people dont point out is they are able to burn 80% of their revenue and still (apparently) remain profitable. This point is key because unlike a lot of projects that might have a good ideal, they are a businesss and businesses need to make money. Geodnet developed their comoany and technology to operate cheaply so they can afford the burns, which creates a positive ferdback loop of keeping rewards up and bringing in more deployers to build the network, that gets more customers, that then burns more tokens.
As am example Hivemapper is a good idea, but their AWS cost is crazy high and as a result they have very minimal token burn; instead the revenue all goes back into operating cost and the token suffers.
Wingbits and Rovr are the ones to watch.
Rovr has a very similar tokenomics(burn) as Geodnet and is following their blueprint + the added benefit that Rovr buys RTK data from Geodnet, which triggers a 20% $geod burn on those fees…but we need to see if Rovr has solved the operating cost aspect, which apparently is coming in the future with their nodes.
Wingbits product is similar to geodnet; you are forced to install correctly to get good rewards so you cant really cheat the system, and every install effectively helps Wingbits coverage advertising. It will be interesting to watch how the tokenomics play out once they TGE.
