Hi warmach,
We are just getting started with this tips for Peercoin on RPi program. We do have a number of Raspberry Pi experts here on the Peercointalk forum, but neither river333 who is running this tipping program nor myself are experts. We are just the verifiers and tip senders. It sounds to me like you may be a RPi expert so, could you help me out here? I don't understand how you can be running a peercoin qt wallet, thus a peercoin node and not be able to show the green check mark? Maybe we need to modify our criterion? What we want to verify is that there is a full Peercoin node running with port forwarding thus having greater than 8 connections. I suspect you will be so we will be able to send you your tip!
If you could help me understand this better that would be great. Thanks.
Edit: Ok got it. SSH is Secure Shell command line. If you were in our shoes what difficult-to-forge criterion would you ask for to verify?
Regarding multiple tips for the same guy, like I said we are just getting started and we don't know how much interest there will be or untimately how much funding we will have. Right now we only have guaranteed funding for 100 tips. But that funding could grow and like I said we have no idea how much interest we will get. So, for now I think we should limit the tips to one per person until we learn more how much interest we will get and how much more funding might become available. Does that sound fair to you?
Thanks for your interest in Spreading Peercoin on Raspberry Pi
