(static, constant) BASE_REWARD :Amount

(static, constant) COIN :Amount

Type:
Source:

(static, constant) EXP :Number

  • Buffer
Source:

(static, constant) GENESIS_REWARD :Amount

Block subsidy specifically for the genesis block.

Explanation: The max miner subsidy is 680000000, but due to the halving interval it actually ends up as 679999995.79, so add 2.21 coins to the genesis reward output to make MAX_MONEY a thoroughly true value.

This, combined with the 3 1/4 year halving interval, causes the supply to run dry after about 100 years (around the year 2119, or height=5,270,000).
