What Is a Block Chain?

A block chain is literally a chain of blocks. You start out with, let's say that's re is te cattle. Say you scan an ear tag, ok? So that data from the ear tag scan goes into this block and it's block zero. And in the next block has its own hash, but also has n the previous hash. Can then take the block all the way down, down down the chain. When each one of these blocks get up dated, all o the blocks in the node automatically get up dated. Unlike a public block chain, like big corn is that anybody can use that. This is a private block chain where you have to have a usual name in pass
