Hi r/Bitcoin. I’m Emiliano Pagnotta, Assistant Professor of Finance at Imperial College Business School. I just published a research paper on the fundamental value and the price of Bitcoin (see link). I’m holding an AMA on the topic here on Mon 16 April at 11am ET

Bitcoin – The Currency of the Internet

Australian Primary School Students Explore Bitcoin and Cryptocurrency Technology (news.bitcoin.com)

Students at Wooranna Park Primary School in Victoria, Australia are experiencing bitcoin and cryptocurrency technology first hand. Wooranna Park Primary’s ‘School on the Blockchain’ program involves a number of initiatives designed to immerse students in blockchain technology, and has seen the school create a unique cryptocurrency called Wooranacoin.

Currency without Borders

IMAGINE IF YOU WERE TO WALK INTO A DELl, ORDER A CLUB SANDWICH, throw some dollar bills down and have the cashier say to you, "That's great. All I need now is your name, billing address, telephone number, mother's maiden name, and bank account number." Most customers would balk at these demands, and yet this is precisely how everyone pays for goods and services over the Internet.

There is no currency on the Web that is as straightforward and anonymous as the dollar bill. Instead we rely on financial surrogates such as credit-card companies to handle our transactions (which pocket a percentage of the sale, as well as your personal information). That could change with the rise of Bitcoin, an all-digital currency that is as liquid and anonymous as cash. It's "as if you were taking a dollar bill, squishing it into your computer and sending it out over the Internet," says Gavin Andresen, one of the leaders of the Bitcoin network.

Bitcoins are bits ─ strings of code that can be transferred from one user to another over a peer-to-peer network. Whereas most strings of bits can be copied infinitely (a property that would render any currency worthless), users can spend a Bitcoin only once. Strong cryptography protects Bitcoins against would-be thieves, and the peer-to-peer network eliminates the need for a central gatekeeper such as Visa or PayPal. The system puts power in the hands of the users, not financial middlemen.

Bitcoin borrows concepts from well-known cryptography programs. The software assigns every Bitcoin user two unique codes: a private key that is hidden on the user's computer and a public address that everyone can see. The key and the address are mathematically linked, but figuring out someone's key from his or her address is practically impossible. If I own 50 Bitcoins and want to transfer them to a friend, the software combines my key with my friend's address. Other people on the network use the relation between my public address and private key to verify that I own the Bitcoins that I want to spend, then transfer those Bitcoins using a code-breaking algorithm. The first computer to complete the calculations is awarded a few Bitcoins now and then, which recruits a diverse collective of users to maintain the system.

The first reported Bitcoin purchase was pizza sold for 10,000 Bitcoins in early 2010. Since then, exchange rates between Bitcoin and the U.S. dollar have bounced all over the scale like notes in a jazz solo. Because of the currency's volatility, only the rare online merchant will accept payment in Bitcoins. At this point, the Bitcoin community is small but especially enthusiastic ─ just like the early adopters of the Internet.
