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. Jan 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.

Here is my merged mining implementation - not quite up to date


None for the normal users. Allow writing to coinbase tx for solo merged miners and pools.
