Description

In the merge mining proxy for the block template protocol:

  • Cached a new block template and used it in case it is asked repetitively for the same best block.
  • Added an exit clause to the potential endless loop.

Motivation and Context

Under certain conditions, a merge mining proxy request for a new block template from the base node would be repeated many times for the same best block height, without the final request for a block template that includes the coinbase transaction. This wastes many resources, especially within the mempool where the template must be constructed.
