Interesting concepts but I'm concerned about fees. I see a lot of people saying Hive tx are feeless but is that really true? I seem to recall there being a miniscule fee, something like 0.01%. How much of a fee are we talking?
I do think smart contracts are way overdue though. I'm anxious to see how the land I have in dcrops can be used in splinter lands or likewise the farms I have in dcity...
In the beginning a small fee will be required per transaction and longer term the goal is to be feeless in a similar way to hive. Regardless, the overall system is designed to be highly scalable, so even if there is a huge amount of network usage, you won't see a massive explosion in transaction costs.
The structure works a bit like this:
I intend fees to never go above 0.03HBD for 99.9% of transactions
That being said this is subject to change and a lot of the fee structures are somewhat arbitrary. The important factor in this is the system is scalability. What that fee ends up being will result in a natural balance between user operations & infrastructure backing.
