If you want to make a fork of Chia, this post key words may be helpful for you.
1 install timelord and start.
if you have a error “error not active for 60 seconds restarting all chains”, please change the 60 to 600 seconds.
2 prepare 10T or 20T plots to boot up.
if you not have enough plots, you can change the NUMBER_ZERO_BITS_PLOT_FILTER value to 1 in default_constants.py file.
3 change port and icon
4 if the NUMBER_ZERO_BITS_PLOT_FILTER is 1, it is very easy and find so many proof, the chain do not how to design which miner is to be give, so you need to increase NUMBER_ZERO_BITS_PLOT_FILTER 1 by 1 and finally find the value to let find a proof in one or two minutes.
in short, too easy, not worked, too difficulty, alow not worked.
I use 11T Plots to boot up,and most case will genesis a block in two minutes. I think it is ok, once the plots is going on, chain will be make block in 18.75 seconds(10 minutes 32 blocks).
I will continus to finish this post.
