## Issue being fixed or feature implemented
Implementation of accepted proposal:
https://www.dashcentral.org/p/TREASURY-REALLOCATION-60-20-20
## What was done?
Once Masternode Reward Location Reallocation activates:
- Treasury is bumped to 20% of block subsidy.
- Block reward shares are immediately set to 75% for MN and 25% miners.
(Previous reallocation periods are dropped)
MN reward share should be 75% of block reward in order to represent 60%
of the block subsidy. (according to the proposal)
- `governancebudget` is returned from `getgovernanceinfo` RPC.
## How Has This Been Tested?
`block_reward_reallocation_tests`
