Cartesi Ecosystem Recap #5

Newsletter/Jan 12, 2024/Marketing Unit

January 12th - gm gm to another new year! We’ve already had a beautiful start with new interoperability horizons opening up for Cartesi-powered dApps - congrats to Fabio, Bruno and the team for successfully bringing Cartesi Rollups to Syscoin’s Rollux testnet!

Plus, the Technical Vision Council’s been busy voting through an integration with the Espresso Sequencer! Following numerous deployments (and an iconic rickroll) on Espresso Sequencer testnets, the new integration aims to explore the expanded dApp design space made possible by Cartesi + Espresso DA. In the medium term, this integration aims to provide valuable lessons for further protocol integrations with other DA layers like EigenDA, Celestia, and Syscoin, bringing Cartesi’s modular vision to life. Check out the original proposal and submit your own in the Technical Vision Forum!

And if that wasn’t enough, take a look at this demo from the Prototype Unit, which showcases how a Cartesi x Celestia combination unlocks data-intensive applications like verifiable video processing on a verifiable Linux VM:

Tech

Research & Design

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

Highlights:

Introducing NoNodo - a lightweight development node for Cartesi Rollups designed to work with applications running in the host machine instead of the Cartesi Machine.
- Why it’s valuable in the development workflow:
  - A replacement for host/no-backend mode.
  - Its only external dependency is Foundry; something Ethereum developers are using already.
  - Doesn’t require Docker
  - Lightweight (10mb), easy to download and easy to get started.
- For the curious: check out the thought process behind NoNodo in the original Technical Evolution Forum proposal.
Rollup Contracts
- V1.2.0 released - contracts deployed to Arbitrum Sepolia, Optimism Sepolia.
- V2.0.0 - close to release. Contracts implement EIP-165, which checks if it implements a given interface - useful for front-end and explorer. Contributors are still working on updating the documentation, improving adherence with the Solidity style guide and testing before release.
Rollups Explorer
- CartesiScan - new homepage with summary-driven content and support to send inputs to applications. In progress - support for ERC-721 token transfers and voucher executions for the next release.
- P.S. Have you grokked Cartesi’s Explorers? On Cartesi, explorers can have a slightly different role because of its novel approach to scalability using app-centric rollups. See what this means in the latest grokking article!
Sunodo - a framework for developing decentralized applications built on top of Cartesi technology.
- Learn more about Sunodo over on its newly released website!
- In progress - sunodo deploy (front-end) - web application used to deploy dApps to testnet and mainnet. Includes financial incentives for running nodes. Stay tuned for a demo of the system…
Prototype & Support
- Transitioning to a new scope - focusing on end-user applications.
- Wrapped up first version of Python high-level framework - now you can pip install python-cartesi. Making it easier to develop Python applications with Cartesi. Big kudos to Felipe Grael for his work on this!
- Check out the python-cartesi quickstart demo in the monthly dev recap call.
Zippie
- Real World Assets - a prototype of a real-world asset verification solution using carbon asset verification as a use-case and testing the integration of the solution to AirImpact’s off-chain carbon asset wallet solution. Done with Cartesi Lambada and Espresso Sequencer technology. Doing 1000 reforestation projects in this manner with established L1 rollups or rollups infrastructure would be too expensive and too complicated to maintain infra for. Check out the demo in action!
- 💃Cartesi Lambada - come and participate in the discussion over in the Technical Vision Forum.
  - TL;DR: Cartesi Lambada is a technological stack designed to provide an alternate means for people to adopt the Cartesi technology.
  - Its main objective is to foster rapid adoption of Cartesi by developers - today; and foster wider comprehension of the Cartesi stack, facilitating its evolution, simpler deployment, and enhanced experimentation.

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!

Set a reminder here to get ready for the next one, Monday 5th February 2024.
