Merged Mining

[Kontakt]

What is the connection between the Namecoin and Bitcoin blocks?
I understand that the midstate for the Nmc is used as the coinbase for the Btc, but why is it that when someone mines a Btc block, they generally get a Nmc block within 10 minutes? There's got to be some connotation I don't comprehend. Can someone explain?

IIRC, this question has come up before, and its usually just coincidence.

It's far, far too frequent to be coincidence. I went back 15 pages, and every Btc block was immediately followed by a Nmc block by the same miner.

Namecoin is based on bitcoin.  When you find a bitcoin, if you are doing merged mining, you *will* find a namecoin block.  The 10 minutes must be how long it takes for it to show up.

When merge mining, every bitcoin block will find a namecoin block. But not every valid namecoin block will be a bitcoin block (when merge mining and as long as bitcoin difficulty > namecoin diff)

Well if the namecoin and bitcoin difficulty was the same, it would be like 100% chance of finding a block from the other network after finding a block on the first network, unless my understanding is incorrect.

Close.  It won't be after, it will be during.  When you find a bitcoin block, it'll be a namecoin block.  At same difficulty, the opposite will apply as well.
