I’m studing blockhain and i do know {that a} block hash is linked to the following block in earlier hash and it cant be modified for legitimate motive.

Cause is : as a result of if somebody have modified hash then then he/she must change in a whole lot or tens of millions of nodes/system additionally in any other case it wont be legitimate.

My query is :
If nonce will probably be modified by some miner then the hash will even get modified and it ought to be altering the following block’s earlier hash.
appropriate me if i’m mistaken. I imply if a miner can change the hash of a block then how he can replicate that hash in all of the nodes or system for that block? that is complicated.
