/* ------------------- Staking Module Hooks -------------------

|
|
|
Rewards are calculated based on total delegated tokens to bonded validators (not shares).
|
|
We need to sync the claim before the user's delegated tokens are changed.
|
|
|
|
When delegated tokens (to bonded validators) are changed:
|
|
- user creates new delegation
|
|
- total bonded delegation increases
|
|
- user delegates or beginUnbonding or beginRedelegate an existing delegation
|
|
- total bonded delegation increases or decreases
|
|
- validator is slashed and Jailed/Tombstoned (tokens reduce, and validator is unbonded)
|
|
- slash: total bonded delegation decreases (less tokens)
|
|
- jail: total bonded delegation decreases (tokens no longer bonded (after end blocker runs))
|
|
- validator becomes unbonded (ie when they drop out of the top 100)
|
|
- total bonded delegation decreases (tokens no longer bonded)
|
|
- validator becomes bonded (ie when they're promoted into the top 100)
|
|
- total bonded delegation increases (tokens become bonded)
