It is good that new witnesses are added, but I guess nobody knows these people who are now becoming witnesses. This is not a problem as such, but if I remember well there was once upon a time the idea that also big institutions would partecipate as witnesses (or perhaps this was just in my mind)
Given that times are not mature for that, did you consider trying to get on board as a witness also people who are well known and trusted in the crypto community?
For example Changpeng Zhao, CEO of Binance, who has emerged as one of the quite respected leaders of this space, and has always shown interest towards new projects with new and interesting technology.

As for most of the activity being on Discord that's a pity, since Discord doesn't really leave a quite immutable trail of the history of the discussions like here on BCT. Best place would be a BCT moderated thread, so that any garbage can be filtered out but the meaningful discussions remain and can be read also in future.
