the version 10.3.1/2 did nothing about stake mining, just accelerate startup and syncing, fix some issues that prevent fork. if you run 10.2.1 which is in the main chain now, you can see the money supply is equal to 10.3.1/2/3, because 10.3.1/2 is compatible with 10.2.1.

i do not notice the history of money supply, the version 10.2.1/10.3.x will generate 0.0009 interest after 9 days now.


10.3.3 further restrict that very old coin will get 0.003 interest at most.
