But that only guarantees safe one way transaction. If that is all you want thats ok.
But for safer transaction you want something like smart contracts. So you can actualy know you are gonna get what you buy for example.
Without some kind of smart contracts you are actualy relying on exchanges (so in reality it isn't really trustless).
Does monero have some kind of smart contract mechanism? In which case I am talking nonsense😂.
its wierd that it is compared by CO2/mass, it would make more sense per callories or some important nutrients.
