Cartesi positions itself as an "Operating System for DApps." It bridges the gap between traditional software and blockchain by providing a modular execution layer where dApps run inside a Linux environment. Unlike shared rollups where applications compete for block space, Cartesi utilizes Application-Specific Rollups, meaning each dApp has its own high-performance rollup chain. The protocol settles disputes on the base layer (e.g., Ethereum) using optimistic rollups.

The ecosystem has focused on removing trusted intermediaries and enhancing developer tooling:

Honeypot v2 & "Dave" Upgrade (Late 2025): Cartesi deployed Honeypot v2 on the Ethereum mainnet, integrating the Dave fraud-proof system. This upgrade introduced Permissionless Refereed Tournaments (PRT), allowing any network participant to challenge invalid state transitions. This critical update was designed to remove the reliance on permissioned validators, advancing the protocol toward "Stage 2" decentralization standards.

Espresso Systems Integration (August 2025): Cartesi integrated with Espresso, a shared sequencer network. This partnership allows Cartesi dApps to offload sequencing duties to a decentralized network, improving transaction ordering and censorship resistance.

RISC-V Emulator Update: The development team released an updated RISC-V emulator in November 2025. This update improved memory management and compatibility, ensuring that the off-chain Linux environment matches physical hardware constraints more accurately.

The CTSI token is central to the protocol's security and data economy:

Noether Staking: Users stake CTSI to run nodes on Noether, Cartesi’s data availability sidechain. Node operators earn rewards for storing the temporary data required by dApps.

Incentivization: CTSI is used to incentivize independent validators who secure the network by verifying off-chain computations.

Dispute Resolution: In the event of a dispute (via the Dave protocol), CTSI is used as a bond mechanism; validators must post CTSI collateral which can be slashed if they are proven to be acting maliciously.
