Enigma's codebase has already been written, it's just a matter of making it work with the current Keycoin code, as well as polishing the UI elements that have to go along with it. Smart contract integration is still conceptual at this point, but we don't think that it will be overly difficult to implement.

Also, we are talking to a few other developers who may be interested in joining the team (no, not from RIPO). That would help immensely with the timeliness of our updates and fixes, as well as allow us to explore even more functionality aside from anonymity features and smart contracts.

The reason this update did not progress smoothly once dynamic interest became a factor again is because dynamic interest doesn't even work on the coin we forked from. Yes, this is our fault and we should have been more conscious of how dynamic interest worked poorly with other coins. But now we may end up creating a system that hasn't ever been implemented in the way we are trying to, which would be a plus.

As for other features, the Keycoin code gives us access to coin mixing functionality, which we may appropriate as part of Enigma, at least partially. We still want to review how well it works among other factors.

Further smart contract features are up to you guys, and as of yet I haven't seen any proposals for features outside of what was outlined in the whitepaper.
