&gt; Even the clearest contract is worthless if one party is too weak to hold everyone to the contract&#x27;s terms. &quot;What, you want me to pay for the work you did for me? Come back with a lawyer and we&#x27;ll talk.&quot;<p>Ethereum solves that: as part of the contract you put the money into escrow, such that if the work is completed the money is <i>automatically</i> delivered to the other guy.<p>Personally I think the problem is on the other side: an automated contract is all well and good, but how can a computer ever make a judgement as to whether the work that was done was compliant with the terms?
