Speaker: David Evans, University of Virginia
Title: Trick or Treat?: Bitcoin for Non-Believers, Cryptocurrencies for Cypherpunks
Abstract: This (non-research) talk will start with a tutorial introduction to cryptocurrencies and how bitcoin works (and doesn’t work) today. We’ll touch on some of the legal, policy, and business aspects of bitcoin and discuss some potential research opportunities in cryptocurrencies.


Speaker: Andrew Miller, University of Maryland
Title: Privacy-preserving Smart Contracts
https://eprint.iacr.org/2015/675.pdf

Abstract: Existing blockchain-based cryptocurrencies such as Bitcoin and Ethereum, store all financial transactions in the clear on the blockchain. This compromises the privacy of financial transactions, which is essential in numerous applications.
Hawk is a blockchain-based smart contract system that stores encrypted transactions on the blockchain, and relies on cryptography to retain the security of the cryptocurrency. A Hawk programmer can write a private smart contract in an intuitive manner without having to implement cryptography, and our compiler automatically generates an efficient cryptographic protocol where contractual parties interact with the blockchain, using cryptographic primitives such as succinct zero-knowledge proofs.
To formally define and reason about the security of our protocols, we also formalize a new simulation-based “blockchain model” of secure computation, which is of independent interest.


Speaker: Ranjit Kumaresan, Massachusetts Institute of Technology
Title: How to Use Bitcoin to Design Fair Protocols
Abstract: I will talk about a recent line of work that integrates traditional secure computation with a formal financial framework. This line of work identifies and abstracts some key transaction functionalities offered by the Bitcoin network, and shows how to incentivize correct behavior in secure computation (and other cryptographic tasks) in a model where parties have access to such a transaction functionality.


Speaker: Matt Green,  Johns Hopkins University
