30 day cooldown time on newly powered up HP for governance voting.
The Hive governance system is made up of both witness voting and DHF voting. When additional new funds are powered up, their weight will NOT count towards governance voting for the following 30 days. This adds a healthy buffer period to any potential malicious coordinated takeover attempt which allows the community a chance to respond, and is an important yet reasonable safeguard to help prevent attacks via funds stored on exchanges without impacting funds in any way.
This is a great security improvement to the chain!
