jl777 is working feverishly on it. I have been in many discussions with him and we've discussed all the possible options for the final implementation of the anonymity for BTCD. He is very determined to meet his obligations.
He has written a super performant Bitcoind daemon (sans mining) which for example he recently got to sync with Zcash. There is some public discussion of this with the Zcash devs, but I am unable to locate the link again at the moment.
James is a C programmer, and doesn't like to use other languages. This some what of a hindrance because it means he relies on others writing the GUIs and those others have apparently cheated and bailed out on him. I am reasonably polyglot in programming languages and platforms, so there was some discussion about me helping him on the GUI work, but I am busy on other work at the moment.
As far as I can tell, James is legit. Every day he is on encrypted chat and even working on Sundays. And he is very concerned about producing the best technology. He is always available for in depth technical discussions. And he displays a breadth of understanding of the technical issues.
When I first started communicating with James in 2014ish, I couldn't entirely comprehend his technical writings. My original observation was he tends to describe things in the way he visualizes it in his mind without considering the terms and issues his reader would not be understand. Yet this has improved a lot, as we have gained more experience communicating with each other.
Apparently James excels at writing highly optimized C code. I can not vouch for whether his strength is writing coherent and correct code, because I don't have enough experience with his code.
Note I asked James about DecentralizedEconomics' allegation that James was the guy who ran for mayor in San Diego and lost. James says he has always been a programmer and that allegation is false.
My rough guess (based only on his statements about progress and having not looked at the code) is he is still a few months away from polished completion.
I am not knowledgeable about why there were delays other than I've heard allusions to some contracted devs taking advantage as mentioned above, about issues of Nxt and Jean-Luc (which I am not really informed about and I'm not interested to know), and apparently because as James dug in he apparently realized he needed to write his own daemon in order to be able to efficiently implement all the features he desires such as the DEX and also browser based clients/wallets. Note I along with TierNolan were in public discussions with him on some of the technical design issues of the DEX. Also James and I have explored many anonymity designs in private over the past year or two. So perhaps some of the delay is due to so much experimentation.
Disclaimer: at the moment, I have no vested position in any crypto currency other than my own vaporware.
Thanks for that honest & fair assessment, very thought provoking coming from yourself!
Glad to see you're 'not back'
