| - | : //Currently, there is no restriction about what a called contract can do, as long as the computation can be performed with the amount of gas provided. This poses certain difficulties about smart contract engineers; after a regular call, unless you know the called contract, you cannot make any assumptions about the state of the contracts. Furthermore, because you cannot know the order of transactions before they are confirmed by miners, not even an outside observer can be sure about that in all cases.// | + | : //Currently, there is no restriction about what a called contract can do, as long as the computation can be performed with the amount of [[dido:public:ra:xapend:xapend.a_glossary:g:gas|gas]] provided.
