Abstract: When Satoshi Nakamoto designed Bitcoin, he had intended it as an “electronic cash system.” However, it is difficult to treat Bitcoin as a form of cash or currency, especially given its price volatility. Still, Bitcoin, as well as thousands of other similar crypto-currencies, allows for the exchange of value in a decentralized and partially anonymous manner. These properties have created opportunities for novel use cases, far beyond the original design goals of Satoshi Nakamoto. As I will discuss in the talk, these use cases span from being unethical to nobel, and from profit-driven to promoting social justice. In particular, three classes of users will be our focus today: (1) criminals who monetize stolen CPU cycles and files with Bitcoin; (2) investors who speculate in crypto-currencies; and (3) human-trafficking fighters who take advantage of a timing side channel in Bitcoin. ——— About the speaker: Danny Y.
