If sub-execution runs out of gas, the parent execution neo vs neos bitcoin sweat coin bittrex thus, it is perfectly "safe" for a contract to call another contract if you set a gas limit on the sub-execution.
As such, the new ethereum 2. Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. Maintain a data store representing something which is useful to either other contracts or to the outside world; one example of this is a contract that simulates a currency, and another is a contract that records membership in a particular organization. The contract checks if the key has already been registered in storage, and if it has not been then the contract registers the value at that key.
