Excellent article.
The blue paper doesn’t mention anything about voting power depleting over time, or about the rate at which this should be set. Maybe this is just a mistake, but it’s not in there anywhere!
Yeah, that part is in the Whitepaper, not in the Bluepaper. It's a bit more complex, but it has a lot more details about the platform.
I have skimmed the white paper, but it's a bit old now so I thought I'd start with this, also this was easier!
