I am not sure how to explain it better right now.
I gave you the full detailed explanation:
1) Block meeting work difficulty target is mined. Difficulty target periodically adjusted so that 1 PoW block arrives every 10 minutes.
2) Work submission is hashed 10 times consecutively. Each consecutive hash maps to an individual unspent output in the blockchain. This is essentially a lottery drawing two sets of five winners. The first five hashes map to mandatory signatures, the final five hashses map to voluntary signatures.
3) If the mandatory signatures map to active public keys [see glossary], the block can potentially be valid. Otherwise, the block is invalid and must be discarded.
4) If PoW miner finds a potentially valid block, he transmits the following hash to the network: {work submission;hash(his block, the previous valid block)}
5) If the work submission meets the difficulty target and maps to active signatories, then the block is relayed through the network. Otherwise, the message is dropped as spam.
5) The first five selected signatories sequentially sign this hash and transmit it onwards as {work submission; hash; sig 1; sig 2; sig 3; sig 4; sig 5}
6) After the mandatory signature sequence is complete, the final signatory publishes the PoW block and also his own PoS block.
7) The final five hashes map to voluntary signatures. These voluntary signatures can be inserted into any block within the next 6 blocks as special txns. These txns do not require fees.
9) Go to step 1
Note: This process is simultaneous so that multiple block hashes can circulate in the network attempting to collect five signatures and generate PoW/PoS block pairs. Block pairs that lose this race are orphaned.
And also a really simplified explanation:
A also told you how to look up more about proof of stake and orphan blocks on your own.
I really wish I could explain it better for you or in words you understand but with all this information above if you cannot understand it we are probably just running into a language barrier.ย Perhaps someone in your native language section could answer for you what are orphan blocks.
