But I mean the Bitcoin blocks, not the Namecoin blocks. I want to find a Bitcoin block that mines for Bitcoin and Namecoin (indirectly).
A Bitcoin block that was used for merged mining of a namecoin block will include as its first transaction the hash of the namecoin block. So looking at BlockExplorer:
Block 184,053 is one of these, I believe:
Click the link for Raw block:
The coinbase includes the hash for namecoin block 60019 ( a7e5dd00502b4aa45a7a68540f654ebb11ad870882af0d77959a0fb6d8307b84 ):
So Namecoin block 60,019 is merge mined against Bitcoin block 184,053.
Coincidentally, the previous namecoin block appears to have been merge mined against the previous Bitcoin block:
But Bitcoin block 184,054 does not appear to have the namecoin hash but it does appear to have some additional hash, probably from some other alt chain.
Bitcoin block 184,057 does not appear to have any merged mining hashes:
