[zapps-wg] Zkproofs.org standards workshop

[Andrew Miller]

That's awesome Lucas, thanks for this input, these are pretty cool
application scenarios. They're all quite relevant to a standards effort
because they seem to involve interfacing between zkSNARKs and other
standardized primitives (password hash functions, anonymous credentials,
extensions to ZSL).
