Cartesi enables developers to build app-specific rollups on Ethereum using any programming language or software available for Linux. Its core technology includes Cartesi Rollups, an optimistic rollups framework, and the Cartesi Machine, a RISC-V virtual machine. This allows complex computations to be executed off-chain, breaking free from EVM limitations while leveraging Ethereum's security.

The CTSI token facilitates ecosystem governance and staking. It powers a validator marketplace where participants stake CTSI to provide services, and token holders can delegate to earn fees. This creates a direct link between dApp usage and token demand, enabling holders to support and benefit from the growth of applications built on Cartesi.
