Cornell is among several other higher education institutions in actively meeting the rising academic interest in this field by offering a total of 28 relevant courses — the largest amount among the world’s top 50 universities as ranked by U.S. News and World Report, beating other Ivy League universities.
Chances are you know someone who’s mined bitcoin. However, cryptocurrencies are not everything they appear to be. Drawing the ire of governments and financial institutions alike, questions about its reliability are on the rise. Prof. Ari Juels, computer science at the Jacobs Technion-Cornell Institute at Cornell Tech, discussed the impact, technology and regulatory environment of cryptocurrencies. Co-director of the Initiative for CryptoCurrencies and Contracts — a collaboration between Cornell, the University of California, Berkeley and the University of Illinois at Urbana-Champaign, based at Cornell Tech — Juels helps lead research on blockchain technology and its applications.
Bitcoin mining consumed nearly one percent of the United States’ electricity last year. Globally, Bitcoin’s estimated yearly power usage is greater than that of Ireland, or 30 times more than that of Tesla vehicles. Considering this, one wonders whether the societal benefits of the world’s foremost cryptocurrency offsets its significant energy consumption, which expedites greater, existential risks like irreversible climate change. Does Bitcoin justify its power bill? First, while Bitcoin is often described as an emerging currency, its illiquidity — you can’t just buy groceries with it — makes it as an asset best-likened to gold.
The internet is everywhere. From simple dial-up connections on bulky computers, the spread of internet access to watches, cameras, printers, refrigerators and televisions demonstrates the progress the computing industry has made. Connectivity is lauded for making our lives convenient and efficient. However, the increasing frequency of malware attacks and data leaks suggests that advancements in cybersecurity are not keeping pace. As a testament to this fact, on Sept.
The opening scene of Christopher Nolan’s The Dark Knight represents the quintessential bank heist. Joker and crew, armed with guns, break into a bank and manage to whisk away gunny bags full of cash. However, not all robberies are this dramatic. As cryptocurrencies become more popular, millions of dollars can be swindled with just the click of a button. In May, Prof. Emin Gun Sirer, computer science, and his colleagues discovered a bug that left DAO, a smart contract that crowdsources investment proposals, vulnerable to such heists.
