What system/blockchain are you asking about? Bitcoin doesn't have PoS, and Pow only applies to blocks as a whole (transactions individually don't have PoW).

I asked because there are some hybrid blockchains who uses POW and POS mecanism and i want to understand how they get stored in the blockchain. POS blocks + POW blocks or mixed Blocks ? could be that there is a fundamental thing that i dont understand.
