According to the article, JPMorgan is simply integrating an open source component of the Zcash project, ZLS - Zero-Knowledge Security, into their own private Quorum project & block chain. This is the future: Thousands of private blockchains that corporations develop and use to automate human labor and remove human fallibility. Blockchain technology is an unexpected push towards the automation of nearly everything.

This development shouldn't be a boon for zCash, except that it validates the usefulness of a component of the software. I would be weary of any coin that doesn't already have a market or have some interesting social implications. Coins need a community to gain true value.

Yup, so maybe it is a bubble.
