So in solo mining, all miners will get the same work , right?
No. As explained before the software feeding work to a miner DOES NOT ALLOW THAT.
All miners pointed at the same pool or private node get different work unless you screw with the code on your experimental node. If a pool does it (sends same work) then whoever operates it is a idiot.
So there is something i dont understand :
To validate a block , a nonce must be found . Miners try to compute a maximum amount of hashes to find it .
In pool mining : the pool dispatches all nonces ( and extra nonces ) to all pools members . The pool gives works ( range of possibilities ) to all pools members . So it's logical that no two members will get the same work
In solo mining : miner try to find the block itself , he tries all nonces. so the work is all possibilities
another solo miner will do the same , so he will try all possibilities .
What's wrong with that ?
