Proposal: Update to issuance equation v2

[plutoegg]

rate = 1000 * (2 — currentSupply/originalSupply)²

The token economics behind the NEC issuance equation needed to be tested in a real environment to help refine them. By the end of the first 30 days, and with the first issuance of new tokens to market makers on Ethfinex, a few possibilities for improvement became clear.

This has lead to the development of version 2 -

Improvements:

• fixed number of tokens (2 billion hard cap) and issuance rate curve
• first order equation (rate not dependent on fees collected but only total supply) —  simplicity has been found to be essential for something like this as the original equation was too difficult to understand and model for most market makers. This complexity made it less attractive to traders who want to understand it and incorporate it into their profit calculations and trading strategies
• simpler to calculate and issue new tokens, since only total supply is required for rate (this may potentially enable it to be done more frequently in the future)
• no longer any dependence on ratio of maker:taker fees in determining number of tokens created during 30 day period
