Enjoying the increased frequency of core-units-updates over on Discord? Or finding it a bit hard to keep track? 😵‍💫 If you’re in the latter camp, don’t worry! Check out a summary of development highlights from June below:

  • Cartesi’s documentation has undergone a complete revamp, supporting documentation for both Cartesi Rollups 0.8 and 0.9 as well as an update for Cartesi Compute (Cartesi’s computational Oracle solution) sections. Read more about what’s new in the upgraded docs portal with this handy guide from core contributor, Nico.
  • The Node unit is laser-focused on the last milestone toward production readiness in the beta stage for Cartesi Rollups.
  • There’s a new version for the Explorer in its repository! The Cartesi Rollups Explorer is now ready to present data for DApps on Cartesi Rollups v0.9.0. A detailed break down of the release is here.
  • A new version for the Emulator SDK is coming and it brings many improvements. More details here over on our Discord channel.
  • The Compute Unit, driven by Zippie, successfully ran the first zkLinux — Linux booting inside a Cartesi Machine (big emulator) inside RiscZero ZK proof at approx 2000–3000 machine cycles per ZK proof segment. 🤯
  • Early documentation for Sunodo is live! It still needs a lot more info and contributions are very welcome. Check it out here.

For the eagled-eyed among us, you might have spotted a new addition in the form of Research and Design meetings! Cartesi’s R&D meetings are now being published on Youtube, granting everyone access to intricate discussions and up-to-date discourse at the forefront of Cartesi tech.
