Sorry, it still doesn't make sense to me. Please explain the meaning of stakeinterest.
The stakeinterest field represents reward for 365 coin*days in satoshi units. I.e. 1000000 value means that you can get 1 NVC (1000000 of satoshis) reward in case if you have
- 1 NVC output with 365 days age
- 10 NVC output with 36.5 days age
- etc
That's a good idea, but you must tell us what the upper limit is (not everybody is a programmer).
It's not ready yet, that's why there is no full explanation at the moment, but it's quite simple. Just one example, if you have two options:
- 1000 coins input
- 10 x 100 coins inputs
there will be no difference in profitability, which is wrong.
Smaller inputs should be prioritized, because it's significantly better for the network, that's why we need this upper limit for the reward. To make sure that there will be no malicious stakeholders, which are able to manipulate by PoS difficulty through using larger inputs instead of smaller ones.
