What about Stone project, which is exactly what you're saying you want to do?

Stone project argues:

I've been experimenting with the idea of using zkSNARKs

At this stage we confirm that Colin's words were right, it's not possible to apply privacy to XRB as we kown it today ( zkSNARKs).

Adding the privacy feature is harder than it may look, simply applying a ZK-SNARKs protocol (the underlying protocol of Zcash) would make the transaction time increase a lot.

That why we are currently working on two approaches:

Having an optional privacy feature, allowing to have instant transaction or privacy
WPI (witness-indistinguishable proof ) approach which for us would be the best way to have both instant transaction and privacy

We hope to confirm very soon that using WPI would highly decrease the transaction time. We are currently working on simulation right now.

I'll then follow both projects, as private dag based crypto seems like the future of crypto imo.
Good luck to you both, and keep us updated!
