This article is mainly to introduce the emerging economic concept of digital gold; it connects to the Iran sanctions only briefly at the end.

What makes gold a natural form of money? Is it just the fact that the metal is so rare? Can’t be, because your dental records are also rare; no one has a set of bites exactly like yours, but dental records are of no value except to dentists, the police, and plane crash investigators.  Is it that gold is so useful? Not really, there are better substitutes for gold in almost any application except in symbolic ways, say, on a Shah's crown. Gold has historically been popular as a form of money because of the combination of its being rare, hard to destroy, impossible to fake, and easy to break into small pieces so that we can carry it on our person, buy variously priced items, and make change. But these days the same properties can be reproduced digitally. Hence digital gold--or bitcoin as it is properly called (BTC).

 

Like gold, bitcoins are mined.  Prospectors with picks and shovels become wealthy if they work hard and strike gold. Similarly you can set your computer‘s math processor working day and night to solve for the right digital signature for a bitcoin. Wrong solutions are worthless, but the right solution passes the “gold” test of every other computer in the bitcoin economy. This coin is rare like gold because the software makes sure that only 21 million coins will ever exist and that only about 6 coins are found every hour worldwide. The bitcoin can be broken up into extremely small piece and with cellphone technology it can certainly be carried around. Add the virtual indestructibility of the data and you get all the attributes that makes gold a popular form of money! Well, all but one: your currency is worthless if no one accepts it.

 

Turns out that one bitcoin is traded these days for about $26, so someone is accepting them! Internet shops have noticed the gold-like qualities of bitcoins and are starting to accept them as payment. For example, you can go through this bitcoin dealer to order pizza from Domino,s or Pizza Hut—Papa John’s coming soon.

 

OK, let’s move on to raising some hackles. By now the reader may have noticed another common characteristic between gold and bitcoins. Central banks have nothing to do with creating them. Governments can’t just create bitcoins to finance wars with “Let There Be Money” fiats the way U.S. Dollars are called into existence. And bitcoins are no one’s business except the buyer’s and the seller’s—so called “peer to peer” transaction. There can be no effective sanctions in a bitcoin global economy, and accounts cannot be frozen because any merchant can deal directly with his/her trading partner anywhere in the world without the need to go through banks. 

Are bitcoins a way for Iranians to get around sanctions? A few are tyring. Business weeks says: "Iranians working or living abroad can send bitcoins to their families, who can use one of the online currency matchmaking services to find someone willing to exchange bitcoins for euros, rials, or dollars. Bitcoins are useful to Iranians wishing to move their money abroad, either to children studying in Europe or America or simply to stash cash in a safe place."

You can even download a song by Iranian artist Mohammad Rafigh for about 0.04 BTC and risk the wrath of the FBI.  Reality is that the bitcoin economy is still mainly in the pizza/video-game/song-download  league. By 2140 A.D. however, when all 21 million bitcoins are in circulations and all other currencies have become extinct, one bitcoin can buy the entire Iranian pistachio harvest (I think!). Though by then these sanctions may have been lifted.
