http://www.cryptocoinsnews.com/news/brock-pierce-realcoin-copied-coinaaa/2014/07/09Realcoin will not be its own self-serving cryptocurrency. It will be based on the Bitcoin blockchain with help from the Mastercoin project. Coinaaa is its own cryptocurrency based on the Bitcoin protocol but managed by Coinaaa AS (our company in Norway). Coinaaa has a centralized blockchain making it impossible to attack (or mine). This gives us full control over Coinaaa, and we can implement any changes that we want if we have to, (because of e.g. new laws or technological problems), while our users will not be affected.
