5) Block reward = keep the same at 50, but with just one minor modification*

* You solve a block. If the current difficulty level is significantly easier than the last difficulty level, your block reward will depend on the results of performing a simple loyalty check. If you can point to a block you solved during the last difficulty era which you did not point to before (i.e., comes from the same address), you get the full 50 coins. Otherwise, you get half (25 coins). The balance of coins are carried over to the next block reward or destroyed.
