It depends wholly on how you want a smart contract to work for your business. Can you give an example? Generally, although labelled 'smart contracts', they would not ideally be a contract upon which you would rely if you were to issue court proceedings for breach (for example, terms and conditions). Any smart contract is agreed, binding and entered into before placing on the blockchain so if you were to be placing your agreed contracts online, the only real benefit would be that the contract is recorded and placed there so it is always available and cannot be lost.
Yes, I want to use smart contracts for a bid project. Something related to gambling. See, two people betting for (let's say) the weather. Bob says
tomorrow is going to be cloudy but Alice predicts
a day with storms and lot of rains; so, they want to put some money, take the smart contract and agree.
Now, happens that Bob don't want to pay and Alice want to make some legal dispute. Is it going to work the smart contract in this case?
You asked for an example.
