About Cartesi and the Foundation

Cartesi enables developers to build application-specific rollups with any code, while benefiting from the security of Ethereum. It bridges the gap between traditional software and blockchain by bringing decades of mature operating systems, programming languages, libraries, and tools to decentralized applications. The Cartesi technology continues to evolve through the efforts of a decentralized ecosystem of contributors.

The Cartesi Foundation is an active member of this ecosystem and supports the development and adoption of Cartesi technology.
