"...Google TechTalk, 8/28/17, presented by Alessandro Chiesa Abstract: In
Bitcoin, a payment's details are broadcast in the clear, so that anyone can
verify its validity. Unfortunately, this violates user privacy and
sacrifices coin fungibility. I will describe the Zerocash protocol, which
uses zero knowledge proofs to achieve privacy-preserving payments in a
Bitcoin-like system. This protocol was recently deployed in the wild, as
part of the cryptocurrency Zcash. "About the Speaker: Alessandro Chiesa is
an assistant professor in the Department of Electrical Engineering and
Computer Science at UC Berkeley. His research spans the areas of complexity
theory, cryptography, and security, and focuses on the theoretical
foundations and practical implementations of cryptographic proof systems
such as zero knowledge proofs. He is a co-inventor of Zerocash and
co-founder of Zcash. He is an author of libsnark, the leading open-source
library for succinct zero knowledge proofs. He has received a Ph.D. in
computer science from MIT in 2014, and B.S. degrees in computer science and
in mathematics from MIT in 2009."

========== Zerocash is not the only one looking at this.
Laws that apply to banks protect a lot from all except governments. Will
governments balk if this gets too good?
