Lead dev (monocolor) answer regarding code rebase questions
https://deeponion.org/community/threads/votecentral-new-proposal-to-modernize-deeponion-codebase.39372/1. The code rebase and upgrade will probably take 3-6 months. But this is a very big work, and requires intensive testing. So this planned time frame could change depends on how the rebase goes. We'll provide regular updates on the progress.
2. DeepSend is currently not our priority, we'll probably release it after the rebase, on the new codebase. But in case the rebase delay, we'll release it in the current codebase. For now, our plan is Q4 this year.
As I said before, Our current focus is on the DeepVault applications, this is what distinguish this coin from the others. It will be really big if we execute it correctly.
3. Based on the community feedback, we will port PoS into the new codebase. Porting SA is in the plan too, but with less priority. We will port TOR, X13, DeepVault, Meek/OBFS4, blockchain verification, PoS, Theme and SA.
I hope this clarifies the questions.
