setParams() is authorized to be called only from the DAO (per modifier) but DAO contract has no corresponding functionality to call setParams() function. As a result, blockDelay  a critical parameter used to prevent flash attacks, is stuck with initialized value and cannot be changed.
Recommend adding functionality to DAO to be able to call setParams() of USDV.sol.
