-### Power Change
-
-Every instance that the voting power changes, information about the state of
-the validator set during the change must be recorded as a `PowerChange` for
-other validators to run through. Each power change is indexed by its block
-height.

- - PowerChange: `0x03 | amino(Height) -> amino(validatorDist)`
