Armor isn't necessary for Mine Blocks, but it makes survival easier by shielding damage dealt by mobs. By placing it in the armor slots in the inventory menu, armor can be worn. There are 5 types of armor in the game thus far: Leather, Iron, Gold, Diamond and the Dragon Scale tier.
Armor provides a random amount of protection (based off of its tier), so calculating the exact amount of damage with armor isn't possible. However, there is a way to estimate how good a set of armor is by the following chart:
|Types||% of damage protection per item worn|
|Dragon Scale||15 ±9%|

In Mine Blocks 1.27 armor can be put on by shift-clicking on it in the items hotbar.
