update on worker budget.
tl;dr: daily worker budget is the minimum of
worker_budget_per_day (from get_global_properties)
24*worker_budget (from the most recent get_object 2.13.X)
It currently is 360k BTS, not 500k BTS
Full write up:
every hour the worker budget is processed, but the budget isn't 500k BTS like i said, that is just the maximum. How it works:
Every second, [ 17/(2^32) * reserve fund ] is allocated for witnesses and workers where reserve fund is how many BTS are currently not distributed. This is defined in:https://github.com/cryptonomex/graphene/blob/f85dec1c23f6bf9259ad9f15311b2e4aac4f9d44/libraries/chain/include/graphene/chain/config.hpp
Every hour the total available reserve fund is calculated by finding how many BTS are available to be distributed and how many BTS will be returned to the reserve fund (i.e., "burnt") during the next maintenance interval.
First find how many BTS have not been distributed:
from_initial_reserve = max_supply - current supply of BTS
max_supply: get_object 1.3.0
current_supply: get_object 2.3.0
then modify it by adding the accumulated fees and witness budget remaining (i.e., 1.5 BTS per block is budgeted, so budget remaining is 1.5 BTS * (number of blocks left in maintenance period+blocks missed by witnesses)) in this maintenance cycle (they will be added to the "reserve fund" permanently at maintenance)
updated reserve fund = from_initial_reserve + from_accumulated_fees + from_unused_witness_budget
variables all from: get_object 2.13.* (choose the most recent one, for example)
new >>> get_object 2.13.361
then calculate how much is available to be spent on workers and witnesses is:
total_budget = (updated reserve fund)*(time_since_last_budget)*17/(2^32)
rounded up to the nearest integer
Ok, now to find how much workers will get in this budget period (1 hour), you find the smaller of the available pay AFTER subtracting witness budget from the total_budget OR the worker_budget_per_day/24 from "get_global_properties"
That is how much per hour allocated for all workers. NOW you rank each worker and pay them one hours worth of pay in order or # votes.
