August 2nd - July was a very busy month, highlighted by EthCC. Cartesi participated in seven events in total: we hosted or co-hosted two, and participated in five as a partner or sponsor. The highlight of the week was the "Drinks & Debate" event co-hosted with Cartesi, where we had some great speakers from top projects discussing important topics such as interoperability and fraud proofs! Spoiler alert, Felten was pretty intense in the first panel.
Let's also celebrate Honeypot reaching the 1 million CTSI mark and still not being cracked!
But let’s talk about that later, let’s first take a look at the updates from the Dev Recap Call to see what Cartesi has been up to lately.

Community News
The Defiant spoke with Gabriel C and Luca from L2beat about fraud proofs and the importance of collaboration in improving them.
Erick wrote a column on CryptoSlate discussing how modularity is not just a technical improvement, but a strategic shift in blockchain infrastructure design that provides a stronger foundation for future applications. Also, don’t forget to check out Guilherme’s article on how to upgrade Web3 applications securely and trustlessly, and discussing the tradeoffs involved.
Activity
As mentioned before, July was a challenging month for Cartesi. The atmosphere at EthCC was great and Felipe’s face reflected it.
The week kicked off with the "Back to the Future" event we co-hosted with Espresso. The evening consisted of two discussion panels and plenty of drinks. The theme of the evening was modularity and Bitcoin L2s. These panels weren't just regular discussions either, to spice things up we asked attendees to write down random words and put them in a bucket, which participants were asked to use during their presentations. Participants who successfully used all five words were rewarded.
Want to know who won? Watch the full panel here.

Speakers:
Felipe Argento (Cartesi)
Ben Fish (Espresso)

Cartesi also participated in the Ethereum United event hosted by Espresso, where they invited prominent players from other industries. The goal of the event was, as the title states, to unite Ethereum. Core contributors Bruno and Siannie were also there to chat with Eurocup fans.
Next up was the much-anticipated Cartesi event this week, “Modular Security, Drinks & Debate with Cartesi,” a small, in-depth discussion on topics like fraud proofs and cross-rollup interoperability, featuring guests from L2Beat, Bankless, Celestia, OP Labs, Avail, Offchain Labs, Espresso, Scroll, and the Ethereum Foundation. There was plenty of interesting discussion.

Erick was joined on the panel by Anurag (Avail), Altan (Near), Deli (Automata), Yoli (Brevis), and moderated by Andy (The Rollup)
Gabriel C gave a keynote on fraud proofs, covering everything we need to know
Gabriel B conducted a workshop on the benefits of leveraging Cartesi
João participated in a panel at L3 Summit discussing misconceptions about L3 and gave a workshop at dAGIhouse
We were also excited to participate in this year’s Modular Summit hosted by Celestia and Maven77. João and Gabriel B led workshops on Cartesi, and Felipe gave a talk on Cartesi’s design tradeoffs and what they mean for developers. At the end of the event, Erick joined the Sovereign Radio podcast hosted by Joeri to discuss Cartesi and all things modular.
Finally, a big hello to the EthCC team! Although the week was very busy and dynamic, the team met every challenge with a smile. From planning the event to participating in discussion panels, recording podcasts, hosting workshops, networking and running around Brussels, they did an amazing job. A special shout out to Karmen, who played a vital role in preparing for the week, even though she couldn’t make it to Brussels in person (skills issues)!

In Brazil, you can see the Cartesi team at Blockchain Rio, where Bruno gave a talk on how to attract the next wave of developers with Cartesi. You can also say hello to us at the Modular Crypto meetup we co-sponsored with Arbitrum and Axelar. Felipe participated in a panel discussing AI and blockchain, discussing how Cartesi fits perfectly with fully verifiable AI. Check out the recap video here.
