**2.3 Inefficient supply chain execution**

Contracts may stipulate that certain actions will take place when certain conditions are met. For example, payment shall be affected when goods have been shipped, or when goods have been delivered. The problem here is that it requires human action, and if the conditions have been met and the human action has not been taken, there is little the beneficiary of the action (e.g., the recipient of the payment) can do. For large financial amounts, international legal action can be taken, but they are very costly and can take years.

If conditions trigger an automated action by a computer system, a risk of hacking exists. It can be forged that the conditions have been met so that action is taken.
