Thursday, Oct 9th – how much do you know about Cartesi? This month, we launched a new campaign designed to help you grok the basics and give a high-level overview of Cartesi tech from Cartesi Rollups all the way to smaller components you might be less familiar with, such as State Fold or Transaction Manager. Take a look at all the articles published so far over on the Cartesi blog, and test how well you truly grok the stack with our newly launched Zealy quests.

Hold up, hold up. Grok? It’s an actual word, we promise! (Elon Musk knows it 😉) Check out the dictionary definition:

P.S. Talking about definitions, check out the new addition to the CoinMarketCap Glossary, Abstraction Scalability, from contributor Gabriel Coutinho!

After launching Cartesi Rollups on Mainnet last month, it was time to put the infrastructure to the test… and supercharge building with Cartesi Experiment Week! A week-long online hackathon for grantees and the broader community to unleash their creativity and focus on bringing tangible dApp ideas, use cases, improvements, and tooling to life.

Safe to say everyone was blown away by the projects that were born out of this week of experimentation - let’s give a huge congratulations to the top 3 finalists:

But the true prize of Cartesi Experiment Week? Getting the community together and excited to build with the Cartesi stack! Check out all the amazing projects submitted in the recap written by Marketing contributor Siannie and why an experiment week is a must-try for every project out there from Advisor to the Cartesi Foundation, Felipe.


Now, let’s head over to tech updates! A frenly reminder: if you can’t wait for next month’s recap, don’t forget you have direct access to developments and discussions over on Discord (check out the core-units-update channel) - come and join the conversation!

Tech

It’s been just over one month since the Honeypot dApp was released on Mainnet - what’s happened since then?


Honeypot is now listed on L2Beat and the funds now stand at 55,540 CTSI. That means over one month of proven security for Cartesi’s infrastructure, as no one has managed to breach it… yet! Come try your hand at cracking it and help battle test Cartesi Rollups security! Need a clue where to start? Dive into this article by Felipe to get familiar with the workings of the Honeypot dApp.

Research & Design


Check out the last live dev recap to hear from the units pushing forward on development:

Highlights include:

  • New features from the Machine Reference Unit as well as continued progress across the Machine Emulator, Web Assembly and Kernel, Tools, and Toolchain workfronts.
  • Cookbooks (and more!) from Prototype and Support
  • Updates for Cartesi Rollups 1.2 and 2.0 release from the Rollups Reference Unit as well as public discussion on pressing research and design questions over on GitHub.
  • Progress on Reader Mode, Single Container and infrastructure to test the node locally from the Node Reference Unit.
  • 🚀 Sunodo 0.9.4 is out and sunodo-templates updated!
    • WARNING: if you have a sunodo application sunodo build can start to fail. Check the Dockerfile of your application and replace the following:
    • -curl=7.81.0-1ubuntu1.13
    • +curl=7.81.0-1ubuntu1.14
    • curl 1.13 has been removed from Ubuntu package repository.
  • New CartesiScan Features from the Explorer Unit!
    • Token deposits into DApps: CartesiScan users can now make ERC-20 token deposits into DApps directly from the explorer. That makes it easier and faster to get started with Cartesi-based applications.
    • Safe Global support: CartesiScan can now be opened inside Safe Global, a multi-chain wallet and asset management platform. That feature allows users to view and manage their ERC-20 assets from a single location.
  • Lots of cool stuff in the works over at Cartesi Compute! From EigenLayer + Tendermint + Cartesi to linking up the Espresso Sequencer with the Cartesi Machine and more, check out the full updates from the month over in Discord or in the call replay.

Tune into the next one by marking your calendars for the first Monday of the month.

Contributor Spotlight

With so many incredible things happening within the Cartesi ecosystem in October, it’s hard to shine the spotlight on just one standout contributor - there are just too many!

This month, let’s shout out Carsten for breaking the Espresso Sequencer with an iconic Rickroll and Danilo for making his second (not to mention consecutive!!) ETHGlobal final with Cryptopolis, the original city simulator but with real economics.

Community Grants Program

Activity remains strong on the CGP front - ETHGlobal Paris track winner DCA Monster passed the community vote, and development is now underway! But what is DCA Monster exactly? Take a look at Pablo’s article to dive into how it made waves within the Cartesi ecosystem and its growing traction in the broader DeFi landscape.

And that’s not the only proposal that the community voted to fund! Check out the proposal from Think & Dev for an on-chain image recognition system using AI algorithms, running on the Cartesi VM and storing results on the blockchain.

For development updates from projects funded through the Community Grants Program,

Events

Our focus isn’t just on Devconnect and ETHGlobal Istanbul! Over in India, Shaheen and Jathin hosted a Cartesi developer showcase (peep the community reaction on Cartesi-powered games) for the Chennai Web3 community, while over in the US, Gabriel and Zach attended All Things Open. Gabriel gave a stellar presentation on how smart contracts need programmability and why Cartesi brings it to a whole new level - recap the weekend with Zach’s roundup thread! In Lisbon, Joao shared insights in a panel on Security beyond Audits at Epic DeFi Security Day, while Augusto joined ETHLisbon as a hackathon judge.

Jathin was on fire this month, hosting a workshop with SRM University’s Blockchain Club, not to mention a trilogy of workshops over in the LearnWeb3DAO community - excited to see even more builders get Cartesi-pilled and can’t wait to see what they build!

Over in the online realm, a powerhouse of a Community Manager and core contributor, Cynthia hosted a panel inviting an incredible range of women from the Web3 space to share their insights about getting started. Make sure to catch the replay and share it with someone you know who’d be interested in getting started!

*P.S. Check out these bonus resources from Deanna, a hackathon finalist at ETHGlobal Lisbon who shared how you can start building with Cartesi.

Without fail, Max brought another star guest to the Game Builder Community Call - we heard from Small Brain Games, who’s on a mission to build a new on-chain game every 6 weeks. Check out the replay:

On the road to Devconnect and ETHGlobal Istanbul, we’ve joined forces with YTU Blockchain, BUChain, OTDÜ Blockchain and ITU Blockchain - hosting a Spaces session all about blockchain innovation and how Cartesi opens up the BUIDLing possibilities!
