Cartesi is a Layer 2 solution with a radical developer-focused thesis: instead of forcing developers to learn Solidity and fit their applications into the constraints of the EVM, Cartesi runs a full Linux environment inside a rollup — so developers can build complex, computation-heavy applications using Python, JavaScript, Rust, C++, or any POSIX-compatible toolchain, then settle disputes and finalize state on Ethereum. CTSI is used for staking in the Noether sidechain (for data availability), gas in the Cartesi Machine environment, and governance. The project targets use cases that are computationally too complex for standard smart contracts — AI models, complex game logic, data processing pipelines.

How It Works
Cartesi Machine:
A RISC-V processor emulator (Linux VM) that runs off-chain but with its execution provable on-chain. Computation happens in the Cartesi Machine; only the inputs, outputs, and dispute proofs go to Ethereum.
Optimistic rollup variant:
Like Optimism and Arbitrum, Cartesi uses optimistic execution with a fraud proof window. If someone disputes a state transition, the Cartesi Machine’s execution is replayed on-chain to settle the dispute.
Rollups framework:
Cartesi Rollups let developers build DApps as normal backend services (in any language), with the Cartesi infrastructure handling L1 communication, state finality, and fraud proof submission.
Noether sidechain:
A PoS sidechain (using CTSI for staking) handles temporary data availability for Cartesi Rollups — nodes are paid CTSI for storing and serving rollup data.
Tokenomics
| Metric | Value |
|---|---|
| Max Supply | 1,000,000,000 CTSI |
| Staking | CTSI staked in Noether sidechain for rewards |
| Rewards | Proportional to staking and uptime |
| APY | Variable (~7–12%) |
| Circulating | ~700M+ CTSI |
Use Cases
- Node staking — CTSI staked to run Noether data availability nodes
- dApp fees — CTSI pays for computation and data availability on Cartesi DApps
- Governance — CTSI holders influence protocol development
- Complex dApps — Power AI/ML inference, game engines, data processing on-chain
History
- 2018 — Cartesi founded by Diego Nehab (Princeton CS), Colin Steil, and Augusto Teixeira
- Sep 2020 — CTSI token launches; Binance Launchpad IEO
- 2021 — Cartesi Machine and Rollups framework launches; CTSI ATH ~$2.24
- 2022 — Rollups v2 with improved API; growing developer adoption in gaming and AI
- 2023 — Cartesi repositions as “execution layer for complex applications”; Linux OS demo applications
- 2024 — Developer ecosystem grows; Rollups framework supports more EVM chains
Common Misconceptions
“Cartesi lets you run any code on Ethereum without constraints.” Cartesi runs code in an off-chain Linux machine and settles disputes on Ethereum — not every computation is on-chain. The on-chain part is the dispute resolution, not the execution itself.
“CTSI is just another DeFi governance token.” CTSI has real utility as a staking requirement for Noether data availability nodes — there’s an operational role tied to the token beyond pure governance voting.
