Grin transaction fees

This infographic seems to say that transaction fees are 4 milligrin per output with a discount of 1 milligrin per input, but at a minimum 1 milligrin of fee.

Is possible to pay less fee?
Is it possible to pay more fee?

If it is not possible to pay more fee, what happens when blocks become full, and what about miners mining empty blocks if they deem fees to be negligble?


It’s not configurable now but I guess it’s going to be once the block size starts being an issue.

Which could be years from now, or even perhaps never.

Are you saying that there will need to be a hardfork, or are you just saying that the current wallet doesn’t support it?

It’s just the wallet that does not support it.

So, the question stands regarding minimum fee. Does it exist, or is tx_weight/1000 just how it’s implemented in the wallet?
