Over the past 18 months, one of the topics that we have discussed and brainstormed with our members has been around privacy and confidentiality. Specifically, who is able to see transactions on a chain or ledger.
While there have been a number of proposals pitched by various groups posted on social media and internet forums, there has been no long form, systematic survey of the privacy and confidentiality tool kit.
Last fall we collaborated with the Zcash team led by Zooko Wilcox O'Hearn and Jack Gavigan, as well as Danny Yang, the founder of Blockseer, to provide a survey on this burgeoning space. We also asked Mike Ward from our APAC team to put together a short view point on their output.
Below are the finished documents originally sent to our members this past November. American Banker got a first look of it and put together an article on the paper as well.
