I think most agree we need to remove volatility from the current EDA
just had 6 today, which is extreme.
My goal was something simple to understand that changes difficulty both up
without large jumps, the large 20% jump maintained over a sequence of
blocks being the main
problem with the current EDA - I believe it would work fairly well with a
smaller change like 2 or
I also wanted to maintain a mean block interval of 600 seconds as that is
Like Shammah said I don't agree that we should be targeting miners or their
it is up to them to mine what they want for whatever reason, they will mine
BCC if it is
stable and predictable without needing a cheap turboblock subsidy.
should be the balancer: their job is to find an equilibrium; we cannot
predict where that is
nor should we try to. But evidence since August is that miners will mine
BCC with a revenue
penalty of up to about 15%, but not much more than that.
The goal should be a stable coin and block production rate whilst
I also wanted to provide an alternative for people to discuss; when
consensus settles on
an algo I will follow that and find a way to implement it in Electron Cash
