What percentage of the total coins will be mined by the devs in the first 100 blocks?
The first 100 blocks will mine 29,995,050 coins. The first 50,000 blocks (about 1 year) will mine 13,750,025,000 coins. Out of the first year, we will premine ~0.2% of the coins.
Sia adds coins to the total every time a block is mined, indefinitely. After 1 year, the inflation rate will be about 95%. After 5 years, the inflation rate will be 6% (this is much lower than Bitcoin's current inflation rate.). After 6 years, the inflation rate reduces to about 3%. It will remain near 3% for many years after that, dropping very slowly.

Ok. It looks like we forgot to update the version number on the UI. You have the correct file.
Maybe the menus are not working because your internet connection is bad? Unfortunately, things don't work if you don't have an internet connection. We are working on fixing this (you won't be able to download blocks, but at least the menus won't be broken). Sometimes it also just takes 30 seconds or so to load. If it's taking longer than that, you should try restarting it.
Thanks for trying us out. Sorry it's not as smooth as it should be. We will push updates shortly.
