Anonymity in Digital Currencies
Public presentation by Elena Pagnin

Bitcoin is the first digital currency to see widespread adoption. While payments are conducted between pseudonyms, Bitcoin cannot offer strong privacy guarantees: payment transactions are recorded in a public decentralized ledger, from which much information can be deduced. Zerocoin tackles some of these privacy issues by unlinking transactions from the payment’s origin. Yet, it still reveals payments’ destinations and amounts, and is limited in functionality. In this talk, I will present the basics of digital currencies and walk though the main steps proposed by the authors of Zerocash to construct a full-fledged ledger-based digital currency with strong privacy guarantees. Zerocash is a decentralized anonymous payment scheme that enables users to directly pay each other privately: the corresponding transaction hides the payment’s origin, destination, and transferred amount.
