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. ``` 2024-03-15 16:49:43.873749100 [minotari_mm_proxy::proxy::block_template_protocol] DEBUG Requested
