How blocks are divided to pools?

How are them?


Every mining pool is calculating a different block? or could them calculate the same block?

How the system works?

It's a lottery. Whoever gets it first wins, and that "win" needs to be confirmed by the rest of the network. So if pool A generates a block at time 1, and pool B generates a block at time 1.0000001, pool A will win, assuming the generation is validated by everyone else.

And since every new block is built on the hash of the previous block, everyone starts over using that hash when a block has been generated. So, in effect, everyone is working on the same block.
