# CryptoNote block reward scheme calculation

The standard CN block reward schedule is calculated using the following formula:

*  Block Reward = (Total Supply of Coins - Already Generated Coins) / (2^emission speed factor)

In the mathematical expression,

* BR = (T - A\*(10^(number of decimals))) / (2^19) / (10^(number of decimals))

For example, let's try to calculate the block reward of the genesis block.\
\
\- T = (2^64) - 1 = 18,446,744,073,709,551,615, a constant\
\- A = 0, This is a genesis block, a varible \
\- emission speed factor = 19, a constant\
\- number of decimals = 8, a constant\
\
Block #1 (18,446,744,073,709,551,615 - 0) \* (2^-19) \* (10^-8) = 351,843.72088832 QWC\
\
For the next block, The calculation is as shown below\
\
Block #2 (18,446,744,073,709,551,615 - 35,184,372,088,832) \* (2^-19) \* (10^-8) = 351,843.72088831 QWC\
Block #3 (18,446,744,073,709,551,615 - 70,368,744,177,663) \* (2^-19) \* (10^-8) = 351,842.37871104 QWC\
Block #4 ... and so on.

The block reward decreases continuously until it reaches a point of tail emission, which is a constant number.
