What are the core changes to bitcoind that allow one to merge-mine? Are there any new JSON-RPC commands that are enabled, or changes to the existing ones?
Just to clarify, the merged mining required no changes to the Bitcoin protocol. Only miners that wanted to do merged mining needed to use a bitcoind with merged mining support.– Stephen GornickJan 14, 2012 at 10:12
@StephenGornick I know that there were no changes to the Bitcoin protocol, I was asking about the changes to bitcoind, the daemon that is used for generating getworks and the like.– ThePiachuJan 14, 2012 at 15:51
None for the normal users. Allow writing to coinbase tx for solo merged miners and pools.
