Ah I think I get it now. So when you try to find a chain, you start with the hash. Let's assume the hash is 100. So then you try 200 as prime origin. If it doesn't work, you try 300. Or maybe you start with 234*100. You always start with a prime origin which can be divided by the hash.

Because now I did some calculations, too. My fallacy was that I thought there are so many big numbers which can be divided by the hash. But now I realize, it is only every 2^256th number. And that is not much...

Ok, thank you guys Wink

But that is good news for me, because if I was right this would be a problem.

Actually, there is still a small loophole. It's possible to discovered a prime chain such that the origin has lots of factors in it. Sunny has outlined the idea in the v0.2 protocol proposal:

It's not really realistic but the protocol is still getting tightened up in the future.

How come a prime chain origin be divisible by any number (except 1 and itself) since it's a prime number ?
What did I get wrong ?
