Not necessarily a bad solution per se, but it isn't frictionless at all.
HIVE POWER should be the gov feature on the Hive blockchain. No need to separate between a 'gov' and 'regular'.
I'm a fan of @edicted sliding power-down period proposal. 13 points = 13 weeks as starting point.
After that let people vote to reduce/increase (every month, for example) this sliding bar by 1 point each time. Over time holders would find their equilibrium being the minimum 1-week power-down.
Good idea but to complex :)
Special on the security point. Will be to random IMO.
Imo 2 power up times would be more easy to handle. Like my proposal i have done a long time ago.
For example 1 week power down and regular 13 weeks. So everyone can split up funds in the weight they want.
Gov can be exclusive 13 week Power up.
Would make funds more liquid. Because its free on how much you power up 1week or 13 week it would give everyone the freedom what they want.
Edit: With a % interface it would it make super easy to handle it :)
btw, Safu were also a good name for Seed :D Something for the next time :D
