Cartesi Ecosystem Recap - November 2023

Newsletter/Dec 5, 2023/KARMEN TRUONG

December 5th - Psst… app-specific rollups aren’t just another scaling solution, they’re in a category of their own. Check out the video explainer we’ve been working on to learn how application-specific rollups are the way to add more processing power to web3 and let builders work on projects that rival Web2 applications.

Wen Roadmap?

Well, with Cartesi Rollups and its first dApp, Honeypot, live on Mainnet, the Cartesi ecosystem is implementing an initial process to determine the technical direction in the mainnet era for Cartesi Rollups. ✨ Introducing the Technical Vision Forum! All Cartesi community members are invited to propose, explore, and discuss technical features that they would like to see included in the ecosystem's Technical Evolution Plan. Curious to see what this looks like? The first proposals have already popped up on the forum - take a look for yourself.

As such, the Technical Evolution Plan will be a living, breathing roadmap for the Cartesi ecosystem that is created by a diverse Vision Council through a decentralized process that allows for broad community involvement and feedback. Who’s excited about this new era?


From Modular Day to ETHGlobal Instanbul, we’ve been inviting web3 developers from all over Devconnect to try hack the Honeypot dApp and drain its funds. Now, it’s just over 2 months old and still remains uncracked, hitting the $10K USD mark (69,965 CTSI). And with 8% compounding allocations weekly, it's set to grow even bigger!

Want to take home an early Christmas gift? Crack the honeypot, and the funds are allllll yours, no strings attached. Plus, you’d be helping battle-test Cartesi Rollups security, so it’s a win-win for everyone! Need a clue on where to start? Check out 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:

  • The Cartesi Machine now boots and runs on Windows, Android, WASM, FreeBSD, and even DOS. Why? Why not! Cartesi is dedicated to opening the design space for people to explore other use cases of blockchain and give feedback on the tech developed!
  • New features on Cartesiscan (a new blockchain explorer for the Cartesi-based DApps)
    • Added dApp connectivity, now users can inspect payloads from vouchers, notices, and reports.
    • A new dedicated page for applications and shortcuts to quickly create a connection for the DApps you know/own. Once created, you can easily see the endpoint that DApp is connected to, including the removal if necessary.
  • Sunodo - deploy verifiable Linux VMs with a click of a button to testnets and mainnets; stay tuned for its upcoming launch!
  • The Prototype and Support team has been cooking up a storm. Here’s just a few:
  • Zippie has started an additional project in the Cartesi ecosystem under a grant with a developer team that is focused on defining and implementing a system architecture for real-world asset verification which utilizes Cartesi verification - check out AirImpact - a digital platform for connecting reforestation developers, investors and buyers in the nature-based carbon market.

Dive into the developments in detail and see them posted in real time over on Discord (check out the core-units-update channel) - come and join the conversation!

Tune into the next one by marking your calendars for the first Monday of the month. Got questions? Don’t be shy - ask your questions to core developers, researchers and contributors directly on Discord!

After internal testing, the team has committed to a specific game mode and will build on this concept. The flow of the new PVE game mode will be as follows:

  • Player enters a stage.
  • After winning, the player gets to choose to continue, get the current reward (based on stage level), or quit.
  • (Completed)
    • Update the game to support 3 enemies simultaneously; it only supported 1 enemy before.
    • Minor adjustment on reward logic: it will now be the last enemy killed that drops the reward.
