RE: Gridcoin reward mechanism and how to improve it

in #gridcoin7 years ago

Maybe I haven't been clear enough about that, I am actually proposing a static PoS reward. Currently the PoB reward is kind of static but the PoS reward not. I think we need to change that. But I think we can do better than just simply switch to a static PoS block reward. In my proposal the PoS block reward is actually fixed to 10 GRC per block as is the 10 GRC foundation reward. Only the PoB reward is variable due to the RSA account.

Regarding the stake weight rebalancing I think we need to do that as well. Since the stake weight determines the probability to stake a block, with a fixed block reward the probability directly determines the PoS rewards you will earn. So that is an integral part of a fair reward mechanism.

Sort:  

Why combine both POS And POB into the one limited block reward? Their limits should be considered seperately.

I don't think there should be a reward cap on POB (aside from max coins created per day) so that users who stake once every few weeks/months (majority of new users not yet using pools) they will get more of their owed balance.

When we remove the mandatory team requirement we face potentially scaling up to the whole active BOINC community, for which there would not be enough coins for everyone to stake frequently enough to earn their owed balance, no?

I agree, they should be seperate. I didn't propose to change that. The PoB rewards should work exactly the same as before just paying out less. Instead of 50,000 GRC per 1000 blocks there would be 30,000 GRC per 1000 blocks.

So if you staked a block the following would happen:

  • you get 10 GRC fixed block reward
  • you get a PoB payout according to your RSA just like today
  • 10 GRC is credited to the foundation funds

The actual numbers are up for debate. My line of reasoning was that if we want the approval of investors the inflation rate should be less than it is today. The PoB reward should be greater than the PoS reward. The amount for the foundation just felt reasonable. 80% for the participants 20% for maintainance, development, advertising, funding science, charity, what ever the network votes on.
