user74853: After searching about how bitcoin miners mining bitcoin work I started to thinking bitcoin miners can cheat in mining bitcoin like they said they has solved the hash and verify it while they don't really solved the hash and verify it so how can it be prevent and anyone please explaining to me? Please? 

user11253: A miner can't simply claim they solved the hash, because the result of the mining becomes part of the next block and everybody else on the network checks to see whether the calculation was done correctly.
If a miner tries to "fake" a block, the trickery would be immediately detected by every peer the miner sends it to, and the block would go nowhere.
