i watched on youtube from 3Brown1Blue channel about "how bitcoin works", it said what makes bitcoin valued is come from the unique hash result of SHA256. for example if someone put string to an argumen function SHA256 like

SHA256("Hello World!")
and consider the result of hash
, there’s 5 zeros at first which we can say unique result. Then that’s result make bitcoin valuable.

Now what if I found another unique result hash of SHA256 with just SHA256 encryptor online manually? How to add it to blockchain so my identity is approved by blockchain watcher that I have it value and how do I get the reward from it?
