Zcash Shielded Assets (ZSAs)

Zcash Shielded Assets (ZSAs) extend Zcash’s shielded pool to arbitrary user-defined assets, so any asset — not just ZEC — can be held and transferred with the same privacy guarantees.

Over the years I’ve made several contributions to the design of the ZSA protocol and shaped ZSA protocol extensions like Assets Swaps and compliance protocols.

E.g.

• Asset swaps — private, atomic swaps between shielded assets. See the ZIP proposal.
• Transaction controls — compliance-aware controls within the shielded pool. See the forum write-up.
