Im interested in learning if a hash of a transaction of dogecoin is predictable in any way or can be manipulated.
thanks if you can help me understand this
the hash of a transaction is created like this in Dogecoin.

in order to predict or manipulate the hash, you would have to manipulate the variables in the equation somehow.
Due to how a blockchain works, this is inherently hard, as , as you can see, it takes previous hashes in account.
Change one variable, the hash changes.
Of course im sure there MAY be ways, but it won be easy. Take a shitcoin with a dead network to test things like this, as obviously you wont be able to change those variables on a network yourself like Dogecoin
