We closed new partnerships aimed at promoting education for children and schools.
We created t-shirts and distributed them to new members, including lawyers.
@michae2xl compiled documents outlining the history of Zcash to provide to lawyers as requested.

James Katz Dev May Report

ZecFaucet Enhancements:

Objective: Continuously improve user experience, operational transparency and security of the community faucet.

Dashboard Launch
- Rolled out a new analytics dashboard at zecfaucet.com/dashboard, providing real-time insights into faucet activity.
Key metrics exposed:
- Claims per hour
- Total faucet claims to date
- Total ZEC sent
- Total ZEC received
- Current faucet balance
- 7-day claims trend chart

ZecFaucet Partnership & Coupon System Prototype

Collaborated with Vitor Pio (Privacy Map) to pilot variable‐payout coupons.

Designed and implemented a coupon engine to issue targeted high-value claims for social campaigns and possible influencer promotions. Hopefully generating engagement and community growth through promotions.

Faucet Security & Fraud Prevention

Objective: Fortify faucet against automated abuse without compromising legitimate user flow.

Proof-of-Work Hardening
- Continued tuning of the existing PoW challenge to throttle high-frequency claim attempts.
- Detected residual scripted claims; analyzed IP and timing patterns for refinement.
- Deployed Google reCAPTCHA v3 atop PoW checks, leveraging invisible risk‐scoring to block suspicious sessions.

Infrastructure & Maintenance

Objective: Ensure 24/7 service reliability across all supporting systems.

Performed minor maintenance on bots and services.
Confirmed all instances (Lightsail, EC2) are updated to latest security patches.

FROST-GUI Demo Progress

Objective: Deliver a user-friendly GUI demonstration for the Zcash FROST threshold-signature protocol.

Current Status: Development pace slowed due to integration challenges.

Roadblocks Identified:
- Tauri is incompatible with the frost-client bindings, which makes a direct integration between them difficult.

If we’re unable to successfully implement the remaining FROST-GUI code, James will reach out to ECC engineers for assistance, since we know they’re all willing to help.

James Katz Dev June Report

Billing

VPC hosting and OpenAI API keys billing payments are up to date.

Discord

Zcash Global maintains bridges that connect multiple Discord servers and channels. This month, I helped Vito troubleshoot and restore a broken bridge between the ECC server and the Zcash Global server. The bridge is now working as expected.

ZecFaucet

General Fixes

Continued working on bug fixes and general maintenance.

GetIpIntel Temporary Block

ZecFaucet relies on the free GetIpIntel service to help detect VPN usage and reduce abuse. In June, the service temporarily blocked our access due to an unusual spike in traffic. I contacted the service admin and successfully restored access.

Critical Challenge Abuse Bug

Identified and patched a serious vulnerability in the challenge-response system:
Users were able to request a challenge, solve it, and then—without closing the modal—open new browser tabs and reuse the same wallet address to request additional challenges. This could be done repeatedly for up to 3 minutes (the challenge validity period), enabling multiple claims. The bug has been fixed and behavior is now as expected.

ZcashMetro

https://ZcashMetro.io stopped showing new transactions in the scene. After investigating, I discovered that the issue stemmed from a change in Zcash’s lightwalletd RPC behavior—specifically in the GetTransaction method. Previously, unmined transactions had a value of -1, but this was changed to 0.

The issue is being tracked here: librustzcash issue #1484

A simple code update in ZcashMetro resolved the problem.

zingolib-wrapper for Node.js

Updated the zingolib-wrapper to support zingolib version 1.11.1 (stable release).

Projects depending on the wrapper can now benefit from the latest stable improvements.

E-ZEC June Report

In June, Zcash Brazil saw a significant boost in community engagement. We hosted multiple online meetups packed with interaction, knowledge-sharing, and onboarding sessions. Our main focus was expanding the community and making sure new members were successfully integrated into the local Zcash ecosystem.

Deliverable 7.1: Zcash Brazil team report: Done.

Michae2xl · September 1, 2025, 1:14am

We are thrilled to announce that we have achieved our 8 milestone of 2025.

Milestone 8 - estimated completion date: 08/31/2025

Full report for August 2025 - 100% complete

We have been carrying out work with a strong emphasis on quality and consistency, operating across several fronts in Brazil. Our members, from different states, value privacy and have been supporting us in this mission. Our focus has been on topics such as self-custody, DEX, and education through Zashi.

NOTES:

I would also like to point out that much of the work happening in Brazil has not been included in the global community summaries. While this is not something we are overly concerned about, it is important to stress that there cannot be divisions, after all, Zcash is one. Community members must come together, not drift apart.
Too often, we see actions that seem designed only to give the impression of work being done, but in reality, they distract from what truly matters. For this reason, I call for attention, and above all, unity across communities. After all, when the circumstances were different, only a few were truly standing on the front lines of this battle.

Highligths

Many of our activities in August were shared on Instagram, through stories and posts, as well as through in-person meetings. Those who followed along could clearly see the dedication and excellent work being done.

At Blockchain Rio 2025, the largest crypto event in Brazil, our team and community members were present. We conducted several interviews, organized local activities, distributed giveaways, and delivered 50 ZecFaucet coupons. In addition, we raffled a Ledger during the event.

Privacy Hour: We launched Privacy Hour, a new program in partnership with the NYM team in Brazil: https://x.com/NymPortugues/status/1957882794715013370

Every Wednesday, we deliver Zcash and ecosystem-focused education through Modular Crypto, the largest educational hub in Brazil: https://x.com/ModularCrypto/status/1959362325300834426

We organized 3 in-person meetups covering Zcash and broader crypto topics:

We launched Zona Z, a weekly series (every Tuesday) with articles on entrepreneurship, freedom, community building, and practical reflections on crypto in everyday life.

We held hands-on workshops covering the Zcash Vote App and other relevant topics: https://x.com/zcashbrazil/status/1961564579353563245

Design Team Iogy & Mine August Report

Here we are at our 3rd Blockchain Rio!

It’s always great to participate in in-person events; we truly felt the heat of the moment! We could sense, especially from those who have been in the crypto market longer, the need for a return to cypherpunk concepts and the urgency for privacy.
We were able to reconnect with friends we’d made in previous editions and added a ton of new ones. We had countless heated discussions about privacy, freedom, rights, regulation, the current situation in Brazil…

We adopted a really cool interview format! AAmandita was our Privacy Reporter and conducted the interviews, which can be viewed on YouTube Shorts and posted on X. It’s a learning experience and a privilege to be able to experience the entire process—recording, editing, and dissemination.

We spoke at booths of projects using ZKP and saw that the issue of privacy is in vogue, but no one knew which protocol was the first to implement it or who Sean Bowe was (:p).
Ultimately, our work isn’t just about adopting Zcash; its history and its Dreamteam of developers are also important, because it’s very pioneering and started as a Bitcoin fork.

We created some new giveaways and others already known at events.

We personally met MLC_SAP, a very active member of the Brazilian community. We also met pac_mcz that day, who literally jumped on board and helped us a lot at the event, joined the community, and even completed a task on Dework.

We ran the ledger giveaway and distributed a card with the giveaway rules.
We ran the Zashi giveaway in conjunction with the Zecfaucet Coupon (another of James’s amazing creations), which was limited to 50 orders for the event, worth USD $2 in ZEC, so users could experience the wallet for the first time as soon as they installed it. It was a two-day event totaling almost 20 hours of standing, practically only sitting down for lunch, but it was totally worth it, and we’re excited to see what new things we’ll bring to the next one.

Here we are

James Katz Dev August Report

As usual, VPS and API keys bills are up to date:

Amazon LightSail
Amazon EC2 instance
OpenAI API keys

Zingolib-Wrapper

Rewritten using nj-cli
- The wrapper was fully rewritten to use nj-cli. Expensive calls can now be executed asynchronously, preventing them from blocking the main Node.js thread.
Upstream dependency issues
- While updating to zingolib 2.0.2, a few compatibility issues with Nu6.1 still remain. These will need to be resolved upstream.

ZecFaucet

Transparent address support on testnet
- Users requested support for legacy transparent addresses (t-addresses) on the testnet faucet. (The testnet faucet is currently offline because Nu6.1 has activated on testnet, and zingolib has not yet updated its zcash-protocol crate.)
Upgrade to zingolib 2.0.2
- ZecFaucet was updated to use zingolib 2.0.2 via the rewritten zingolib-wrapper.
Balance reservation:
- The faucet now reserves a balance for coupon redemptions, ensuring that the faucet balance cannot be drained by normal claims.
Anti-fraud mechanisms:
- Two new measures were added to reduce automated and fraudulent claims:
  - A sliding puzzle captcha.
  - A global cooldown window, during which the faucet temporarily refuses new claims after heavy usage.

Infrastructure & Community Tools

BTC-Pay Server with Zcash support
- Installed and tested BTC-Pay Server configured for Zcash payments. A deployment was successfully set up for Zcash Brasil. Plans are in place for a future tutorial or workshop to help others integrate BTC-Pay with Zcash.
Zcash Vote Server
- With guidance from @dismad, we successfully configured and deployed the server after a full day of work. It’s a pleasure to contribute by running a piece of the core infrastructure required for the coin holders poll to take place.

A special thanks to Jason (@aquietinvestor) for the invitation to participate.

E-ZEC August Report

In addition to the activities carried out by Zcash Brazil, we successfully onboarded new community members who connected with us during Blockchain Rio 2025. These fresh faces bring new energy and perspectives to our growing ecosystem.

Amazing work

Hi @Michae2xl by Global Community Summaries do you mean the Ecosystem Digest?

Michae2xl · September 1, 2025, 11:31pm

Hey @squirrel

Yes, I’ve noticed some irrelevant content in the weekly digest, which impacts Zcash Shielded News. For example, the last digest referred to “Zcash Shielded News 40,” while we’re already at 45 (5 weeks ahead).

Just one sample among others → Zcash Ecosystem Digest | August 24th - ZecHub

I appreciate the ongoing tasks, they’re valuable. However, we could improve quality by increasing incentives for better submissions.

squirrel · September 2, 2025, 6:38am

Thanks, this is something we can address. Feel free to reach out if there is anything else so it can be fixed right away

James Katz Dev September Report

Billing

All AWS, OpenAI, and hosting bills are paid and up to date.

Community

After the coin holders’ poll was closed, I assisted with an independent audit of the results. My audit confirmed that all results matched the official publication.
Supported a Brazilian community member participating in the ZecHub hackathon. Their project leverages the new zcash-walletd library to use Zcash shielded memos.

Development Work

zcash-walletd

Started a new project: zcash-walletd

Originally forked from Hanh’s GitHub, the code was generalized into a reusable library.
Created Node.js bindings, enabling developers to use it as a view-only Zcash wallet.
This foundation will be useful for future projects.

Testnet Faucet & Nu6.1

With ZecHub’s hackathon ongoing, many participants requested testnet tokens. I implemented a temporary hotfix for the faucet so users could continue testing their projects.
Update: Shortly after my hotfix, Zingolabs released a proper Zingolib version with Nu6.1 support. Both zingolib-wrapper and zecfaucet were upgraded accordingly.

Closing Notes

This month was focused on upgrades and community support, ensuring tools and infrastructure remained available for ongoing projects and hackathon participants.

Zcash Shielded Call

Community Support Contribution

During the Zcash Shielded Call, I actively supported the livestream by encouraging community participation and engagement. My contributions included:

Promoting the event on social media to increase visibility
Stimulating interaction by inviting viewers to ask questions to the guest speaker
Facilitating dialogue and feedback from the community
Reinforcing the importance of shielded transactions and privacy in the Zcash ecosystem

This strengthens community bonds and ensures that members feel heard and involved in the ongoing development of Zcash Brazil.

Changing World – The Great Crypto Reset with Casta

Casta is one of the most influential crypto communicators and educators in Brazil, known for his deep knowledge and impactful presence in the community.

I took on the full responsibility of promoting his work to the broader community audience, ensuring maximum visibility and engagement for this YouTube livestream. My efforts included:

Clarifying and showcasing Casta’s contributions to the community
Bringing in as many users as possible to join the live event
Providing continuous support before, during, and after the stream

This initiative was all about strengthening the crypto ecosystem and amplifying the voices of those who truly educate and inspire.
