Calculating Block Rewards ​

To determine the block reward from inflation, we must know the Virtual Supply (sum of all $KOIN + $VHP). Lets assume the following conditions:

vhp.total-supply = 50,000,000

koin.total_supply = 50,000,000

Virtual Supply = 100,000,000

We must also know the several constants:

Average time to produce a block = 3 seconds

Inflation = 2%

With this information, we can calculate the block reward as follows:

Step 1

Determine the total blocks in a year:

(365 days x 24 hrs/day x 60 mins/hr x 60 sec/min) / (3 second blocks) 
= 10,512,000 Blocks/year

Step 2 Determine 2% of Virtual Supply:

100,000,000 x 0.02 = 2,000,000

Bare in mind that the 2,000,000 value is only used to determine the current block reward! The virtual supply changes every block and the block reward is always adjusting.

Step 3 Divide the inflation reward by the total blocks per a year to determine the instaneous block reward:

2,000,000 / 10,512,000 = 0.1902587519 $KOIN/block

The Virtual Supply now increases by 0.1902587519, and the calculation is done again for the next block with the updated Virtual Supply.
