Bitcoin Textbook to Become Available from Princeton
March 16, 2016
Bitcoin is all over the media but this form of currency may not be thoroughly understood by many, including researchers and scholars. An post on this topic, The Princeton Bitcoin textbook is now freely available, was recently published on Freedom to Tinker, a blog hosted by Princeton’s Center for Information Technology Policy. This article announces the first completed draft of a Princeton Bitcoin textbook. At 300 pages, the manuscript is geared to those who hope to gain a technical understanding of how Bitcoin works and is appropriate for those who have a basic understanding of computer science and programming. According to the write-up,
“Researchers and advanced students will find the book useful as well — starting around Chapter 5, most chapters have novel intellectual contributions. Princeton University Press is publishing the official, peer-reviewed, polished, and professionally done version of this book. It will be out this summer. If you’d like to be notified when it comes out, you should sign up here. Several courses have already used an earlier draft of the book in their classes, including Stanford’s CS 251. If you’re an instructor looking to use the book in your class, we welcome you to contact us, and we’d be happy to share additional teaching materials with you.”
As Bitcoin educational resources catch fire in academia, it is only a matter of time before other Bitcoin experts begin creating resources to help other audiences understand the currency of the Dark Web. Additionally, it will be interesting to see if research emerges regarding connections between Bitcoin, the Dark Web and the mainstream internet.

No Evidence That Terrorists Are Using Bitcoin
February 23, 2016
If you were concerned virtual currencies like Bitcoin are making things easier for Islamic State (aka IS, ISIS, ISIL, or Daesh), you can rest easy, at least for now. The International Business Times reports, “Isis: Bitcoin Not Used by Daesh.” That is the conclusion reached by a Europol investigation performed after last November’s attacks in Paris. Though some had suggested the terrorists were being funded with cyber money, investigators found no evidence of it.
On the other hand, the organization’s communication networks are thriving online through the Dark Web and a variety of apps. Writer Alistair Charlton tells us:
Better known by European law enforcement is how terrorists like IS use social media to communicate. The report says: “The internet and social media are used for communication and the acquisition of goods (weapons, fake IDs) and services, made relatively safe for terrorists with the availability of secure and inherently encrypted appliances, such as WhatsApp, Skype and Viber. In Facebook, VKA and Twitter they join closed and hidden groups that can be accessed by invitation only, and use coded language.”
se of Tor, the anonymising browser used to access the dark web where sites are hidden from search engines like Google, is also acknowledged by Europol. “The use of encryption and anonymising tools prevent conventional observation by security authorities. There is evidence of a level of technical knowledge available to religiously inspired terrorist groups, allowing them to make their use of the internet and social media invisible to intelligence and law enforcement agencies.”
Of course, like any valuable technology, anonymizing apps can be used for weal or woe; they benefit marginalized peoples trying to make their voices heard as much as they do terrorists. Besides, there is no going back to a disconnected world now. My question is whether terrorists have taken the suggestion, and are now working on a Bitcoin initiative. I suppose we will see, eventually.

Trust and Security Lessons Offered by the Dark Web
January 27, 2016
Spreading lessons about trust is not what most people think when they think of the drug dealers, hackers and cyber criminals of the Dark Web, but an article from Medium begs to differ. Let’s hear it for the bad guys: What the Dark Web can teach us about trust focuses on the idea that these “bad guys” are successfully and efficiently making transactions, ultimately based on trust. The article states:
“Crucially, they offer the same kind of reliability of experience rather than ripping people off, thus creating a sustainable business model. Transactions are made using digital currency Bitcoin and are recorded and verified through a distributed public ledger called the block chain. In this way, such sites build trust by offering a straightforward transaction built on transparency, albeit achieved with complete anonymity.”
This trust may be seen as missing from many internet sites where collection of personal data is the price of admission; the Dark Web offers an alternative with the promise of information not being tracked. Ironically, the issue of information being collected, albeit through other means, and sold through channels in the Dark Web means the problem of security is not eradicated.

Banks Turn to Blockchain Technology
November 9, 2015
Cryptocurrency has come a long way, and now big banks are taking the technology behind Bitcoin very seriously, we learn in “Nine of the World’s Biggest Banks Form Blockchain Partnership” at Re/code. Led by financial technology firm R3, banks are signing on to apply blockchain tech to the financial markets. A few of the banks involved so far include Goldman Sacks, Barclays, JP Morgan, Royal Bank of Scotland, Credit Suisse, and Commonwealth Bank of Australia. The article notes:
“The blockchain works as a huge, decentralized ledger of every bitcoin transaction ever made that is verified and shared by a global network of computers and therefore is virtually tamper-proof. The Bank of England has a team dedicated to it and calls it a ‘key technological innovation.’ The data that can be secured using the technology is not restricted to bitcoin transactions. Two parties could use it to exchange any other information, within minutes and with no need for a third party to verify it. [R3 CEO David] Rutter said the initial focus would be to agree on an underlying architecture, but it had not yet been decided whether that would be underpinned by bitcoin’s blockchain or another one, such as one being built by Ethereum, which offers more features than the original bitcoin technology.”
Rutter did mention he expects this tech to be used post-trade, not directly in exchange or OTC trading, at least not soon. It is hoped the use of blockchain technology will increase security while reducing security and errors.
