# account_subsidy_budget is the per-block budget.
# A value of 10,000 (STEEM_ACCOUNT_SUBSIDY_PRECISION) represents a budget of one subsidized account per block.
# account_subsidy_decay is the per-block decay rate. A value of 2^36 (STEEM_RD_DECAY_DENOM_SHIFT) represents 100% decay rate.
# The default decay rate (347321) corresponds to a half-life of 5 days
