# Initial Total Supply starts at 0.
2
# You can mine this token using the mine() function
3
# It generates 2 random numbers and if they match, you will get one token and the supply is upped by 1.
4
# The range of the numbers that get generated by the random function is increasing as more supply is minted, which results in higher difficulty to mine
5
# There is a burn of 2% on any transaction to fight inflation
6
# Lets get that node hot by mining!
