# CTSI (Cartesi) Research Brief — As of 2026-09-16

## What Cartesi Is (Context)
Cartesi is a modular Layer-2 execution layer that boots a Linux OS inside its virtual machine ("Cartesi Machine"), giving developers access to standard code libraries for building app-specific rollups [[10]](https://www.datawallet.com/crypto/cartesi-explained)[[28]](https://cartesi.io/about/). CTSI is the native token used for governance, staking, and validator-marketplace incentives [[11]](https://cartesi.io/ctsi-token/).

## Recent Catalysts (Last ~1–3 Months)

**August 2026 – Machine Stack Shipments**
- **Machine Emulator v0.21.0** shipped, along with new alpha releases for **Rollups Contracts**, the **Sequencer**, and **browser-ready Machine bindings** (TypeScript tooling) [[2]](https://cartesi.io/blog/ecosystem-updates-august-2026/)[[3]](https://x.com/cartesiproject). This is core engineering progress on the app-specific rollup stack rather than an end-user product launch.
