# ZCash Forum Post (July 2022)

<!-- copy/paste below this line -->

Hey everybody, just wanted to update you all on what the Ziggurat team has been up to over the last couple of months.

*Context*: These updates are based on the deliverables detailed in [this grant proposal](https://zcashgrants.org/gallery/25215916-53ea-4041-a3b2-6d00c487917d/23814137/). The relevant deliverables here are the re-testing of Zebra and zcashd, and the network crawler.

If an item is omitted here, it is not yet in progress.

## Progress as of July 2022

By our estimation, we are roughly 50% of the way through the grant. Below are details regarding specific deliverables.

## Pre-flight checks

We refreshed the Ziggurat codebase with dependency updates, various refactors and improvements following the release of new Rust compiler versions, and updates to our implementation of the Zcash network protocol (Nu5). We've also improved the test specification by introducing a [clearer symbolic language](https://github.com/eqlabs/ziggurat/pull/124) to describe test cases.


### Re-testing `zcashd@v4.7.0` and `zcashd@v5.0.0`

A top priority was to re-test the latest version(s) of `zcashd`. We sent a number of disclosures to the node developers, including but not limited to the following public issues.

- https://github.com/zcash/zcash/issues/6038
- https://github.com/zcash/zcash/issues/5168
- https://github.com/zcash/zcash/issues/5259
- https://github.com/zcash/zcash/issues/6039

The re-test of `v5.0.0` is in progress, no disclosures yet.


### Re-testing `zebra@v1.0.0-beta.8-12`

We decided to additionally re-test Zebra as well. This is currently in progress. We have sent disclosures for `beta.8` privately and no official issues opened yet.

Once we hear back we will open issues and/or move on to `beta.12`

### Network crawler: Alpha status

We completed a solid version of the network crawler. However, before we officially release anything we are liasing with the node developers to make sure the crawler is performant and the metrics returned are as meaningful as possible.

Once we're confident in the state of the network crawler, we will provide instructions on how to use it.
