More robust fee mechanism

[ghost]

Based on a quick read, it seems to me that Grin rewards the miner by simply adding the fees.
In the literature [0] it has been suggested that this is suboptimal from an incentive point of view, as it results in more complex bidding strategies and a bad user experience.

I suspect it's non-trivial to adapt the suggested changes for Bitcoin to Grin, but haven't so far seen it mentioned anywhere, so thought I'd put it on the radar.

Hi, thanks for making the suggestion. 👍

Grin's fee structure is actually actively being revised at the moment, see details in this RFC that is in Final Comment Period: mimblewimble/grin-rfcs#63

And there's also this tracking issue: #3369

If you have concrete suggestions on how the current RFC proposal could be improved, please raise them in the RFC pull request ASAP as it is about to be finalised soon and development will commence to target v5.0.0.

In the meanwhile, I'm closing this ticket as a duplicate.
