Hey, @joeylim.

I'm wondering what this person you were talking with would want as far as decentralization goes that would be better than witnesses? I mean, the practical use can get messy when humans are involved, yes, but a purpose of being a witness is to run a witness server to keep the blockchain up and running and blocks validated. This is done on several servers in different locations throughout the world, rather than on one server usually ran by a corporation or an organization. So, in that respect, witnesses are decentralized.

If we speak to governance, well, the witnesses would have to have a 17/21 supermajority to make any kind of changes. Right now, I'm not sure how well that works, but when everyone is doing in their job as they should, things that aren't ready for the blockchain don't go on the blockchain, and unless there's that level of consensus, changes aren't supposed to take place. I think in theory, that's a good thing. How the execution of it takes place is another story.
