In do_become_delegate the LastTxBlock is used to ratelimit the coldkey's transactions. So, effectively we are limiting how frequently can a coldkey make its hotkeys become delegates based on how frequently it stakes / unstakes.
This might not be an issue, just making an observation. Please close if this is OK.
Rate limiting implementation only uses
TotalHotkeyColdkeyStakesThisIntervalmap here:https://github.com/opentensor/subtensor/blob/86b7f6dd702cf173ca98d683d6d01cc402ea9854/pallets/subtensor/src/staking.rs#L312
But here is sets both
