Great question. Yes, Bitrated is indeed centralized, but strives for a model that requires putting as little trust as possible on the service operator. For example - user reviews, contracts and profile fields are signed with the user's

So, after originally launching Bitrated as an MVP [1] more than a year ago and getting some very positive responses, I spent the last 10 months working on a new release at a full-time capacity. This is the result. :) The new release is a co
