How to run the BCHN vs ABC benchmarks quick and dirty guide

Quick and Dirty Guide to Running the ABC vs BCHN Mining Benchmarks

This is in reference to the results published here: https://old.reddit.com/r/btc/comments/gdlapl/bchn_now_40_faster_at_mining_than_abc/

The benchmarks were thrown together quickly for me to characterize our progress. As such, these instructions are for advanced users. I am posting these instructions in the interests of transparency and so you can "see for yourself". These instructions assume Linux or OSX and do not work on Windows, as far as I know.

Requires: python3, cmake, ninja, boost, and libbdbdev. I forget what these are called on Linux packages -- consult our docs about how to build and requirements.

  1. Clone my BCHN repo: 
    

    2.

                Protocol commands/features needed by Electron Cash if it were to switch to bchd
              
          

        

      

        

  

      

    
Protocol Commands bchd Needs to Implement for Electron Cash to Switch


Hi, Calin here. I noticed bchd is almost there with respect to featureset.


I'd very much like to switch Electron Cash over to bchd as its wallet service/backend/data provider and move away from ElectrumX for basically two reasons:


    

  • The maintainer is antagonistic towards BCH
    • 

  • ElectrumX (and the version we maintain, Electron X) has serious performance and scaling issues because it is written in Python
    •
