ACE Seminar: ZCash: past, present, and future of an Anonymous Bitcoin like Crypto-Currency

Speaker: Ian Miers

Date/Time: 10-Aug-2017, 16:00 UTC

Venue: Gordon Street (25) - Room 500



In this talk I detail the past, present, and future of Zcash, the first completely anonymous crypto-currency, and associated work. Crypto-currencies, first introduced by Bitcoin, make use of an append-only ledger, termed a blockchain, that is maintained by an ad-hoc peer-to-peer network. With blockchains, unlike older approaches to digital cash, we need not trust any individual provider in order to trust the currency. Instead, we need only assume that some majority of the network’s computational power is honest. The downside to this approach, however, is that blockchains are completely public. Payments made with crypto-currencies can be analyzed and tracked by anyone, including businesses seeking information on their competitors or stalkers seeking personal data. This talk covers my work resolving these privacy issues.


Ian Miers works on applied cryptography, including crypto-currencies and secure messaging, at Johns Hopkins University. His Ph.D. dissertation, "Decentralized Anonymous Payments," focused on privacy for blockchain based payment systems. He is one of the inventors of Zerocoin and Zerocash and a co-founder of ZCash. His work has been featured in The Washington Post, The New York Times, Wired, The Economist, and denounced in at least two op-eds.
