Cartesi allows developers to move beyond shared computation and EVM design limitations. *A full CPU for each DApp With Cartesi Rollups, DApps don't compete with each other for processing power like they do on Ethereum and existing L2 scaling solutions. *A full suite of open-source libraries for your DApp With the Cartesi Virtual Machine, DApp developers move beyond the EVM and gain access to the full suite of code libraries, programming languages, and open-source tooling they're accustomed to. *Cartesi Rollups can be used as a layer two, a layer three, or as sovereign rollups.

[Cartesi](https://cartesi.io) is an [app-specific rollup protocol](https://cartesi.io/blog/application-specific-rollups/) with a virtual machine that runs Linux distributions, creating a richer and broader design space for DApp developers. Cartesi Rollups offer a modular scaling solution, deployable as L2, L3, or sovereign rollups, while maintaining strong base layer security guarantees.
