I see instructions on how to add BLS keys,
2. Setting up BLS Keys - Harmony.
What is not clear is how you would go about removing a single BLS key if you lose enough stake and are no longer being elected. Whenever I want to increase or decrease my number of slots, do I simply create an entirely new set of keys and discard (or backup) the old ones? I always assumed I’d add or remove 1 key at a time, but it’s really not clear from these instructions how you could explicitly remove a single key. As a follow on, the instructions say all BLS keys must be on the same shard, but when I look through the validators I can see they are being elected to slots on multiple shards…are the instructions out of date? Any help on these questions would be appreciated, thanks!
