Say I sell you some rope and as part of our contract I say that it shouldn't be used to execute people and you go and use it to hang someone. How would you even go about expressing that in the world of a blockchain? How does the blockchain world get to know that you have broken your side of the contract. How does a blockchain contract enforce penalties for breaking a contract?

This is known as the “oracle problem”; actually getting the correct real world inputs into an immutable smart contract is a serious hurdle to adoption.

If you pay attention to most smart contract pitches, they polite side step this issue.
