Hello Zcash community!
We have been steadily making progress on the integration of ZSAs into NU7, including working with the other teams involved to integrate subsequent additions to the NU7 features.
As can be seen in our regular updates, we have a feature complete version of ZSAs available with a testnet, and we have completed the OrchardZSA protocol changes. The review of the orchard crate is currently in progress.
As the reviews take place, we expect to continue with critical core protocol updates to discuss and finalize the review suggestions. This will start with the orchard repository, and changes will propagate upwards into librustzcash and zebra, and so on as each repository gets reviewed.
We have also prepared the reference test vectors for the ZSA changes. A review of this is in progress as well. We will be integrating them with the other NU7 changes so as not to have a divergence between the reference vector implementations.
We are expecting this work to occur in Q1 2026. We will need a smaller team than before since we are expecting more review based changes than fresh development work. We are sharing here a link to our grant proposal on GitHub.
As always, we’re looking forward to see our development work bring value to this community!
Best,
The QEDIT Team.
