Bitcoin Lecture - Zerocash: Zerocoin meets SCIPR-lab

Agenda:

19:00-19:30 - Gathering and refreshments
19:30-20:30 - Zerocash: Zerocoin meets SCIPR-lab (Eli Ben-Sasson)
20:30-22:00 - Free discussion

Bitcoin's Anonymity Problem (BAP) is that when Alice buys coffee from Bob using Bitcoin, she can learn when and how Bob respends her coin, and Bob can trace back the origin of Alice's coin and perhaps connect it to other coins she may possess.

Zerocash is a new decentralized anonymous payment (DAP) system built on top of Bitcoin. It solves BAP by extending the set of Bitcoin transactions with fully-anonymous fungible and divisible transactions that hide payer, payee, and payment amount.

The construction uses recent advances in the area of succinct computational integrity and privacy (SCIP). Joint work with Alessadro Chiesa (MIT), Christina Garman (JHU), Mathew Green (JHU), Eran Tromer (TAU) and Madars Virza (MIT).

The talk will be given in English.


We would like to start the lecture at 19:30 sharp, so please make an effort to arrive on time, taking traffic into account. From 19:00 you'll have the opportunity to enjoy refreshments and socialize.


As always, the talk will be recorded for those of us who can't attend.


Parking is recommended at the nearby Azrieli Center (7 minutes walk, about 12 NIS for the entire night).
