Asalamu Alaykum, Make istikhara
Surprisingly, or maybe not, religious studies automatically re-emerge as a practically useful academic field.
It takes 3 persons to trade, not 2: The buyer, the seller, but also the one who will be the judge of it, if things go wrong. As you know, pretty much the entire technology clan utterly rejects the government for the role of judge or
conflict manager. That is why lawyer in man-made law is a dead end field. Technology continuously seeks to eliminate government-appointed judges and their lawyers.
That is why we have the system of
multi-signature transactions in bitcoin. The buyer is able to produce one signature, the seller another one, and the
adjudicator the third one. The decision of to whom the money goes, is made by 2 signatures out of 3. If buyer and seller do not get into a dispute, the buyer just releases the payment to the seller. If there is a dispute, the
adjudicator will side with either the buyer of the seller.
At
bitrated.com you can find a peek preview of the future, already growing fast today. Also look for addresses in the
blockchain starting with a "3". Those are multi-signature.
At bitrated, buyers and sellers can search the
adjudicator profiles for their specific experience, and select an appropriate one. The adjudicator will charge a nominal fee at the start of the transaction and generate one of the signature keys. The buyer will then transfer the amount escrowed into that 2-of-3 address, after which the seller will deliver the products or services.
Since no government is involved in such transaction, it would be rather difficult and also undesirable to pick a particular set of national man-made laws to govern it. At the same time. religious law is considered to be fair, even by people who are not necessarily religious. In this environment, you will find that people will happily agree with ulema in the position of
adjudicator, i.e. scholars in Islamic law. The scholars will have to specialize in particular types of transactions, concerning particular types of products or services, but that is not the hard part, because the hard part is much more about being fundamentally fair, and administering justice cleanly.
Anyway, it is technology that decides who exactly will get a role in these transactions, while we all agree that governments will not get one. At the same time,
ulema will naturally emerge as the perfectly suitable profiles for the role of putting conflict to rest.
