Fine talk for those doing comparisons of
Monero vs the Zcash family regarding privacy etc...

"...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?
