Btcd is now a sleeper but it's very alive and it's going to be a very important piece in a larger set of tools that requires all other piaces to be in place as well in order to get the maximum benefit.

You can hardly see the progress here on BTT, the den of trolls, because most discussions take place in Supernet Slack(channels #iguana # btcd), James also posts frequent updates in bitco.in forum where the mods created a section for Iguana. He's is coding like a mule and github gets daily updates. Also a team of people is helping with gui and testing.

James is developing this brand new Bitcoin wallet called Iguana that is coded from scratch in C. Unlike the other clients available, Iguana is extremely optimized and allows to create a full bitcoin node in a fraction of the time of other implementations. Beside being a Bitcoin wallet it also includes a Btcd wallet, Pax (pegged assets), Pangea (decentralized poker), Teleport (privacy), Instantdex (decentralized exchange), Jumblr (bitcoin mixing) and all other Supernet features.

Iguana could very well get mass adoption from Bitcoin users who wish to run a full node, also many users who currently use a spv wallet could change back to a full node since it will not be as painful as it used to be. Imagine when they see the other features and a fraction of them become Btcd/Supernet users and you get an idea of where all this is going.
