thanks a lot
...
Just saw these new posts.
I could be wrong but wouldn't circulating supply be the current top block?
At any rate, I'm not the dev and not quite sure what you are asking? (I am sleep deprived right now which isn't helping..)
The question goes to one of the several core devs who showed up here and worked on extending the code, long ago. They changed the block reward, and my post further back explained how I reflected that in the block explorer mined/supply totals.
But the last update/s are not included yet, so I am asking for the exact block number/s at which the block rewards were changed.
It won't cost me much time to include that information into my block explorer code, I just need to get the numbers right.
