Cool, then I'm eagerly waiting on updates :D
How do you plan on taking these architectural decisions ? You already got the ideas and just need to implement them or are some "big" points still unclear ?
Anyway, have fun coding ! And if you feel like it once you've made some headway, live streaming some coding (and maybe some Q&A with people following the project) could be really nice. If you manage to build a little community even before the chain is launched, it would greatly improve its chance of success.

By the way, I made a little post about my thoughts on Steem DPoS and how to fix it to prevent any more hostile takeovers in the future. It's short, if you want to give it a read : https://steempeak.com/steemhostiletakeover/@art.int/my-thoughts-on-steem-dpos
We never know, that might be similar to what you're thinking of (in the case you're staying with DPoS of course).
