Will, one thing you will love about this is:  I said it's "free", but actually not quite, nothing is free.  But I have analyzed the cost of sumbitting a DNS record, and it comes down to about 1 micro sat.  Imagine doing something pretty useful for 1 microsat, and how granular an economy you can make.  Then we start to price everything in microsats, get a full ultra micro economy gong where the units do something useful. 

 Pkarr is not free, in the same way sending few hundred udp packets is not free. It definitely costs something!

But joking aside, running Mainline nodes costs something too, mostly your time to open a udp port or setup a VPS, we are just amazingly fortunate that Bittorrent provided enough incentive to do it other than our idealistic goal of sovereign identities. 

All hail media piracy. 

 I qualified that in my next post.  I think it could be about 1 microsat. ie 1/1,000,000 of a satohi
