Hi, How the Bitcoin network checks for the same block number creation in two different wallets ?

[Gabi]

Mh...can you explain better? Same private key?

[romanticon]

Yep, your machine is generating numbers that will become a blocks and my , I can
understand that in that bit size it is not very common but you know when
all the world will use Bitcoins it is possible, or maybe I am missing something.

ooh! you mean like block being generated, like transactions and the next block. but not the same
right? do i understand the problem correctly, or have i missed something?

I mean , to generate the block all I need is  to find a number  that is lower than a target ,
what if you will find the same number in the same time or nearby and will claim the ownership
on the money in the block.

oh now i understand! they can't find the same block, with the same hash(yes they can but its very very unlikely.). because the ownership of the reward, is a transaction in the block. that transaction is used to build the merkel tree, along with all the others transactions. and that merkel root will be included in the block, and it will change the hash of the block.

that why you also not can steal others blocks, if you tryed to put in a fake reward transaction, the block hash would change, and thereby invalidating the block.
