The maximum share supply is dictated by the largest power of 10 less than 2^63 which is 1 Quadrillian. 1,000,000,000,000,000
The initial share supply was selected to be 10,000,000,000,000 in satoshies... 1% of the maximum supply.
The initial share precision was selected to be 1,000,000.
This makes representation of the initial share supply to be:
10,000,000.000000 or 10 million
There are several potential dilution strategies:
1) Deflation (delegates paid a fraction of fees)
2) Steady State (delegates paid 100% of fees)
3) Steady Pay (minimal dilution) (delegates receive pay equal to the minimum transaction fees in a full block regardless of actual transaction fees.
4) Targeted Growth (delegates paid X% of the difference between current shares and maximum shares at any given point in time.
Under the Targeted Growth model I would suggest that the Initial Shares equal 20% of the Maximum Shares so that AGS/PTS holders are never diluted beyond 20%.
Initial Share Supply 200,000,000.000000
Maximum Share Supply 1,000,000,000.000000
First Year Delegate Pay: 160,000,000.000000 (~1,600,000 per delegate on average (0.44%))
End First Year Total Supply 360,000,000.000000
Second Year Delegate Pay: 128,000,000.000000 (~1,280,000 per delegate on average (0.26%))
End Second Year Total Supply 488,000,000.000000
After 10 years the supply will be 860,000,000.00000
Under these plans, the price of a "share" when the market cap equals bitcoin would be ~5% of bitcoins share price or less. We can adjust the precision as necessary. I could see starting out with 20 billion and having 4 decimal places, this would cause the shares to be priced around $1 at bitcoins market cap.
These are just ideas.
