Thanks for the summary @geebell. Looking forward to listening to the hangout later.

Regarding the interest payments, having a constant block reward for PoS that gradually decreased over time, eg halving every set number of blocks similar to bitcoin (210,000 for btc) might be a good way to emphasize BOINC rewards over PoS rewards as time goes on. If PoR is also used to secure the blockchain then that would also lessen the requirement for paying out large PoS rewards. At the moment however it may be a necessity to reward stakers well in order to secure the network.

Regarding commercialization, IMO there is nothing inherently bad if companies or users want to set up projects for commercial purposes. I think we should eventually make it easier to do so. We could set up a requirement to burn coins in exchange for computation which would create a demand for gridcoin and incentivize more open research. Either that or have a portion of coins sent to an address for funding development.

Keep up the great work!
