"In 2008, a person calling himself or herself or themselves Satoshi Nakamoto released a paper suggesting a system for an anonymous, peer-to-peer alternative money. Bitcoin was born. Although not the first digital currency ever proposed, nor the first challenger to fiat money, bitcoin is the first to have captured the broad imagination of speculators, coders, regulators, criminals and the mass media. This course puts Bitcoin in context: how do we understand money as a social, political and technological phenomenon? From discussions of ancient transactions to the rise of state-issued currencies, we will explore the social and technical aspects of bitcoin, its predecessors and potential successors, and how its features echo aspects of many different historical transaction systems. No prior knowledge of economics or computing is required. There is little academic writing on bitcoin. And this may be the first truly academic class on the topic. We want to put bitcoin in a wider perspective, to reflect on what it means for society, politics and economics, as well as how it helps us think about money both a social and a technical phenomenon. This class is not an advanced seminar on bitcoin--we will not be delving deeply into the inner workings of the system, but instead providing a bird's-eye overview with enough technical detail for you to be able to put media stories, hype and hope around bitcoin in perspective. Similarly, this is not a class in monetary economics--we won't go too deeply into monetary theory or policy, the money supply, or inflation. Instead the class invites you to think more deeply about one of the oldest systems of technology on the planet, and most ubiquitous: money, whether coin, cash, credit card or cryptocurrency, we humans have been making money for most of the past 10,000 years. How we do so in the future is a question bitcoin just maybe helps us answer."

🎓First Academic Conference on Blockchain Technology🎓🇮🇱 On January 25, 2017, IDCBeyond, and the IDC’s Media Innovation Lab, hosted the first academic conference in Israel dedicated exclusively to Blockchain Technology at the Adelson School of Entrepreneurship. Discussions with a range of entrepreneurs, investors and visionaries -- including Eden Shochat (Aleph) and Matan Field -- as well as talks with key players in the industry from Microsoft, Deloitte, and IBM. 🌟GIDEON GREENSPAN🌟 OPEN V CLOSED BLOCKCHAINS AND REAL WORLD APPLICATIONS Gideon Greenspan is a developer, entrepreneur and lecturer. Gideon Greenspan is a founder / CEO of Coin Sciences Ltd, a company developing a suite of technologies and services for public and private blockchains. Gideon Greenspan is a multilingual coder with a PhD in Computer Science and MA in Philosophy (London). As a hobby Gideon teaches software entrepreneurship at two universities in Tel Aviv. «As a computer scientist I see blockchains as a fundamental advance in what can be achieved with databases and networks. As an entrepreneur I see many opportunities for new products and business models». 🌟🌟🌟Follow us https://www.facebook.com/BeyondBlockChain/ “This is an exciting new technology that holds incredible potential to disrupt a wide range of fields,” explain IDCBeyond event organizers Emmanuel Benhamou and Anna Kulik. “There’s been a lot of hype around Blockchain in recent years, but we wanted to hear directly from the industry’s key players and entrepreneurs, many of which are right here in Israel.” “This [technology] is going to bring about the second internet revolution,” claims blockchain researcher and entrepreneur Matan Field. ”This will not only impact every facet of our life, every industry, but it will also lead to new social organizational structures in our society.” Mark Smargon, of the blockchain startup Colu, explains, "Fintech is all about improving the online banking experience for consumers, and blockchain is the effort to improve the infrastructure underneath it and create new business models.” The one day conference is being organized by participants of the IDC’s new flagship entrepreneurship program, IDCBeyond. “IDCBeyond focuses on creating ventures which deal with the challenges of the 21st century. Blockchain aims to address one of these key challenges, that which deals with the financial mechanisms the world turns on. We are honored to support the initiative started by a group of IDCBeyonders from our inaugural class of 2017 and to host the first academic event on blockchain in Israel,” says Nava Swersky Sofer, Managing Director of IDC Beyond program.
