Bitcoin, Payment Privacy and Beyond: Blockchains as Limited Trusted Third Parties

Dr. Ian Miers

Blockchains have received considerable attention both in academia and industry. Much of this work has focused on how to improve blockchains themselves either in terms of performance, features, or theoretical underpinnings. This talk will focus on a different question: what can blockchains do for computer security and cryptography? It will cover blockchains as a solution to pre-existing problems with anonymous credentials and e-cash, fairness in MPC, and more broadly as a tool for assured communication and state-keeping in cryptographic protocols.
