+"Vault blocks": blocks with a high reward that are immediateley payed to the Mjollnircoin Vault when mined. Once the block is payed to the Vault, it will be auctioned and the highest bidder wins the vaulted block which is then payed out to the winner either directly or through an Escrow Service. The assumption here is, that when Mjollnircoin hits the Bittrex Exchange the value goes go up (which would then not be a bad investment)
+
+The reward of such a vaulted block should be high enough to make it worthwhile and the starting bid should be such that we only need a scarse number of
+these blocks (perhaps as few as 10, with a reward of 25000 MNR for example).
