From my research the devs are not MIA but working in conjunction with Stratis, and in Q3 will combine with the stratis team fully, Id say its a bit of give and take in that you scratch my back and we will scratch yours. In amazed at how it took investors so long to find this coin as its been in the stratis whitepaper for ages. Its enough for me to see a stratis whitepaper stating blitz will be sidechained to think that blitz might be their ace in the hole.
