Blastcraft was developed to provide protection against the destructive forces in the ICBM mod. Each block available in Blastcraft can withstand a direct hit from a Missile. It is very useful in the field of construction of missile-proof buildings, i.e. bunkers and military bases. Not only against the protection of your enemies, but also to protect your home, in case you make any mistakes in the crafting process of your own Explosives.
Barbed Wire is a good way to keep mobs out, and to outline your territory to other players.
