Zcash Brazil | 2025

[Michae2xl]

We are thrilled to announce that we have achieved our 12 milestone of 2025.

Milestone 12 - estimated completion date: 12/31/2025

Full report for December 2025 - 100% complete

• Marketing & Growth - @Michae2xl Report
• Technical Support - @james_katz report
• Design - @Iogy & @Minevg report
• Community Support- @E-zec report

Highligths

The year 2025 delivered exceptional results, surpassing all expectations. The team’s strong commitment, which resulted in new partnerships and enabled us to overcome numerous challenges while achieving key objectives. Privacy has emerged as a critical issue in the market, and it demands our full attention moving forward. We are prepared for an even more intense global effort in 2026.

I believe our greatest achievement was, once again, arriving in December and receiving another vote of confidence, as our proposal was approved to continue through 2026. I would like to express my gratitude for the approval of the proposal.

James Katz Dev December Report

This month was quieter in terms of feature delivery, but important groundwork and maintenance work continued across infrastructure and ongoing projects. With the year coming to an end, much of the focus naturally shifted toward stability, review, and planning for a stronger start in 2026.

Infrastructure & Operations

• Infrastructure stability:

  • All core infrastructure remains online and stable, including 4 AWS Lightsail instances and 1 EC2 instance, with billing fully up to date.

• API services:

  • OpenAI and xAI API keys are active and paid, ensuring uninterrupted access for dependent services.

• Zcash infrastructure:

  • zebrad and lightwalletd continue to run 24/7 without issues at infra.zcashbr.com, providing a reliable backbone for Zcash-related services.

Development & Maintenance

• Dizzy – Faucet command:
  • A new faucet command was launched but surfaced issues shortly after release, likely related to API behavior.
    During investigation, a bug was identified where multiple incoming transactions sharing the same txid were not being registered correctly.
    A fix has been implemented at code level, adjusting the deposit-check logic to iterate over each received note within the same txid.
    This fix is not yet tested or deployed and will be validated in the next cycle.

LiveZEC:

• Work continued on a basic demo of LiveZEC, the live-streaming donations platform. The project is still in an early, unfinished state and will require further development moving forward.

ZebraPi OS image:

• Custom ZebraPi OS images were successfully built; however, the resulting images did not function as expected in practice.
  Additional debugging and testing are required, and changes still need to be pushed to a dedicated GitHub repository.

ZECA (ZecHub Hackathon project):

• Initial planning resumed for officially implementing ZECA on the Zcash Discord server.
  The intended design involves a dedicated channel where users can scan a QR code, send shielded Zcash transactions, and have memo contents replicated by a bot.
  This feature has not yet been implemented and remains in the planning phase.

Improvements & Fixes

• ZecFaucet UX improvement:
  A small but important usability fix was deployed.
  When the faucet is closed for coupon holders, the claim amount and address input field are now hidden, preventing user confusion.
  This was the main change fully completed and shipped during the month.

Closing Notes

Overall, this was a slower month in terms of visible output, largely due to the end-of-year period. The focus leaned more toward maintenance, issue discovery, and planning, rather than shipping major new features. Several initiatives are partially complete and positioned to move forward, with the intention of starting 2026 with clearer direction and renewed momentum.

Holydays

We really enjoyed making songs talking about Zcash! “A Golden Year for Zcash” is a tribute in the form of a Christmas song that praises the achievements of 2025 not only in terms of the development of the protocol, but in the growth of the community.

PapaiZoel (a Brazilian Zcash Santa)

Papai Zoel arrived at the Zcash Brazil server, distributing tips among the community, those who have always been with us throughout the Zcash Brazil journey and, like us, never gave up.
An action for the Brazilian community, encouraging activity on the server, praising those who stood out and participated the most throughout the year. Encouraging onboarding with the family, not only talking about Zcash but also introducing the importance of privacy.
