Ah okay thanks for helping. I guess in the case of RaiBlocks, since you're only transacting currency (not Turing complete smart contracts) there isn't really a need for fees to prevent the halting problem like you have with Ethereum.
I've made a list of tokens that I'm trying to categorize[1] so I think I've got RaiBlocks in the right place.
Is Bitcoin slightly over designed in how the fee structure is implemented for the problem it's solving?
