Not understanding this exactly....
"miningfund": 225263.55100000
Is miningfund the burned donations ? Also what is the 580800 ?
If there is a specific burn address because can also have it tracked.
The 580800 coins were the premine. That amount comes from the first 6050 blocks (6050 x 96 ixc block reward).
On the last wallet update, those coins were locked and added to the mining fund so they could be mined again. The
mininfund command shows what's left of said premine + donations.
You can track the donations with the block explorer links I posted before.
