In writing the white paper for the BPN implementation, I have been back and forth with the team regarding the current voting poll (cost for a BPN). Yes, a BPN should be an investment and the earning potential will justify the investment, however this is not the only consideration. I bring this point up because the 2k CBX option is presently leading.
The issue I have with this is that in order for us to maintain PoSP and implement BPN, we must split the network coins so we can allow different interest earnings percentages for each function (BPNs should earn more as they provide more services to the network).
Essentially this means splitting the 1 million total CBX into halves of 500k CBX each. One half would be used for PoSP at 1% annual inflation (interest earnings projected from this would be in the 3-6% annual range). The other half for BPN would be at 3% annual inflation so the two would balance out to our 2% inflationary target.
Additionally to make BPN operation more lucrative, we will limit the total number of BPNs to max out at 250k CBX (1/4 of the network). This means that if all of the BPN slots are filled, the absolute minimum interest earnings would be 6% per year. Going off of our PoSP history, we can extrapolate that the return will actually be 3-6 times higher than the inflationary rate from the BPN half therefore rewarding in the projected range of 9-18% yearly for BPN operators.
So with this outlined we come back to the current survey. If we set a BPN cost at 2k CBX, then the maximum number of nodes we can have on the network would be 125. If however we set BPN cost at 500 CBX, then we can have a maximum of 500 BPN on the network and better decentralization.
