Because it isn’t totally anonymous yet, it doesn’t exist. Nor is it secure etc. There’s a design being implemented which we’ll be able to test and try to break during tests.
DBC, if feasible gets us more confidence in the level of secure anonymity the network can achieve, and as a bonus will makes for a more efficient solution (less work for sections, more done by the clients), and the added functionality of offline transactions.
Given this is being explored without distracting any developers from getting the testnets up and running, I don’t understand why some folks are concerned about it. We’ve known MaidSafe wanted to look at DBCs as a potentially better solution for some time, and IMO it’s great that they are so close to the testnets that they have the spare capacity to do this.
