By saying that lightweight wallets in an indirect way are a possible solution to blockchain bloat suggests that it will be a problem if Dash is widely adopted on an international scale. Lightweight wallets are off the blockchain and as such could be viewed as being prone to becoming centralized with all the perils associated with centralization.
The Dash evolution release will solve that problem. Maybe someone can post the direct link to that info or i will do it later. Got to run for now.
