Maria Carmo YouTube

Overview

Maria Carmo 369 is a Portuguese-language video channel where a Brazilian educator walks viewers through blockchain projects, grant proposals and developer tools. Videos run from conference reports filmed on location to numbered workshop series that build a topic step by step¹. The host co-founded a stake pool and files grant proposals herself, so the coverage comes from inside the ecosystem.

Most of the catalogue is about Cardano, and one series covers Midnight, a privacy-focused network built to work alongside it¹. Maria Carmo was among the founders of Cardanistas, a Portuguese-speaking community stake pool in Brazil², and has put proposals to Project Catalyst, the grant program ADA holders vote on, since its first funding round³. Titles and narration are mostly Portuguese, with English used on some of the developer material¹.

Key Features

• Ecosystem coverage in Portuguese. Brazilian and Portuguese-speaking viewers get explainers, project reviews and ecosystem news in their own language rather than through subtitles⁴.
• Numbered workshop series on Midnight. A short run of videos works through the privacy network's tooling in order, covering the tool that turns code into privacy circuits, the server that generates its cryptographic proofs, and how its two tokens work¹.
• Conference reports from Cardano Summit stops. Coverage from Cardano Summit stops in Rio de Janeiro and Buenos Aires includes panels¹.
• Grant proposals explained by the person filing them. Walkthrough videos take viewers through Catalyst submissions on community hubs, adoption campaigns and education projects before the community votes¹.
• A delivery record anyone can check. Her Catalyst proposer profile lists the submissions she has made, which ones were approved, and the amounts requested and paid out³.

What to Expect

Presentation is plain: a host talking to camera, sharing a screen, or holding a phone at an event. There is no fixed schedule: the channel publishes in bursts, with a cluster of videos around a conference or a funding round and quieter stretches in between¹.

If you do not read Portuguese, three of the four Midnight workshop videos carry English titles¹, but the spoken narration is Portuguese. YouTube's automatic captions and translation cover the rest roughly, and screen-shared demonstrations are followable regardless of language.

The channel is one surface of a wider body of work. Maria Carmo has taken Catalyst-funded projects through to completion, including a community hub programme in Brazil⁵ and the Portuguese subtitling of a Lovelace Academy video course on writing Cardano smart contracts⁶. She also published a Portuguese-language newsletter on Substack, with posts on governance, Brazilian tax rules for crypto, and artificial-intelligence projects in the ecosystem⁷.

The channel's about page points viewers toward the Cardanistas stake pool⁴. A stake pool is a server that helps produce blocks, and ADA holders can delegate to one to earn a share of the network's rewards while their coins stay under their own control.
