I’ve been looking at the architecture for Chia, and trying to understand pools.

If someone wants to be a pool operator, they would receive 7/8 of the block reward for any blocks created by the pool participants. How will the pool know what fraction of the reward to distribute to the participants?

I understand that as a farmer, you can submit a proof of space to the pool - but that is a one time thing. If the farmer deletes the plots later, how will the pool know?

I feel like I’m missing something here.

In the POW space - it’s pretty easy to know how many hash jobs were submitted by participants. What is the equivalent “proof” for chia?
