@Edicksonjga put together this analysis of relative performance along with instructions for independent verification.
We’re looking into soliciting independent contributors to perform their own benchmarks, to replicate-or-contradict findings.
We see several significant performance enhancements, as documented below.
(Again this is @Edicksonjga 's work, and we’re interested in ironing out replication procedures to get independent observations.)
CAVEAT: We are also testing our new zainod offering (another dimension of variability..) and would be interested to see benchmark results against a zainod endpoint. Interested parties can reach out and we’ll furnish a zainod endpoint.
Pepper-Sync in the Zcash Ecosystem
I have tested on multiple platforms (iOS 26, Windows 11, and Arch Linux) using a wallet with a real transaction history and a block height of 2,900,000. The goal is to provide up-to-date data on the performance of Pepper-Sync on Zingo Mobile and Zingo PC.
Optimizing Fund Availability
One of Pepper-Sync’s core technical pillars is prioritizing user utility. Results demonstrate that users can transact long before the technical process of the full scan is complete.
| User Metric | Zingo Mobile/ZingoPC Result (Pepper-Sync) |
|---|---|
| Funds available to spend | ~1:30 min |
| Total synchronization (100%) | ~5:00 min |
| Spend Before Syncing | Yes (Active and Functional) |
Cross-Platform Stability
Tests conducted on desktop computers and mobile devices demonstrate fast application performance and synchronization, regardless of the operating system used. As you can see in the videos:
- Zingo PC (Windows 11/Arch Linux): ~5 minutes for total synchronization and ~3 minutes for funds to be available via Spend Before Syncing.
Evolution and Technical Progress
In comparison to previous years and after sandblasting, where synchronizing a similar range of blocks could take between 20 and 60 minutes, the current Pepper-Sync implementation allows the process to be completed in 5 minutes, with funds available in as little as 90 seconds.
This improvement represents a qualitative leap in the usability of ZingoLabs applications, prioritizing immediate utility and the efficiency of the synchronization engine.
Test Data
- Software: Zingo Mobile 2.0.18 (305) / Zingo PC 2.0.10.
- Library: zingolib_v3.0.0-0-g8a663aa6.
Full audiovisual records of each test, supporting these times and the fluid performance of the interfaces, are available at the following link (Mega folder).
This folder contains videos of various Zcash wallets.

How to run your own tests
- Install ZingoPC or Zingo Mobile.
- Restore your wallet or use our test wallet:
daughter safe tonight pull clarify discover gesture sting carry shine cup tourist say six ignore benefit wise argue issue above invest milk holiday source
- To restore on ZingoPC: Click on Wallet and then Add new wallet.
- To restore on Zingo Mobile: Open the menu and tap Restore or Open a new wallet.
- Add the birthday height:
2900000 - Tap on Restore.
What to expect
The synchronization process will begin. For this number of blocks, a full sync typically takes between 5 to 10 minutes. However, you should see spendable funds within 1:30 to 3 minutes.
Note: Performance results will vary depending on your device, the wallet version, the server, and your internet connection.
Pro-Tip
As an active user in the Zcash ecosystem, I recommend changing the global ZecRocks server to a different one. Because it is often saturated, you may experience occasional connection issues.
If you want to compare these results with another app, simply download and install it, then repeat these steps following the specific UI instructions of that application.
