Cartesi

Cartesi is a Linux-based optimistic rollup protocol that lets developers build decentralized applications by running rich off-chain computation inside a sandboxed Linux virtual machine. The core of the stack is the Cartesi Machine, a deterministic RISC-V emulator that boots a real Linux userland so dApps can be written in any language (Rust, Go, Python, JavaScript/TypeScript, C++) using familiar libraries, then settle results on Ethereum and other EVM chains through Cartesi Rollups smart contracts. Cartesi Rollups 2.0 is the current major version, packaging an application-specific rollup as the combination of the Cartesi Machine, the Cartesi Rollups Node middleware (Rust + Go), and a set of Solidity rollup contracts that handle settlement, consensus, and data availability. The DAVE permissionless fraud-proof system provides Stage-2 trust minimization, while the Cartesi CLI (the successor to Sunodo) packages scaffolding, build, and local devnet workflows. Cartesi is stewarded by The Cartesi Foundation and the CTSI token governs the network. Cartesi is fully open source under Apache-2.0 and LGPL-3.0 licenses on github.com/cartesi; there is no proprietary SaaS product, but the Rollups Node ships several developer-facing surfaces — the Rollup HTTP API used by application backends, the Inspect HTTP API for read-only queries from frontends, a GraphQL reader for advance-state inputs / outputs / vouchers / notices / reports, and a JSON-RPC node API for operations.

Cartesi is profiled on the APIs.io network. Tagged areas include Blockchain, Layer 2, Optimistic Rollups, Ethereum, and EVM.

Cartesi’s developer surface includes documentation, API reference, CLI, GitHub presence, engineering blog, YouTube channel, and 24 more developer resources.

Open Source Surface applies to this provider. This product is open source and we read its repository directly, so Open Source Surface carries 10 points of the composite. It is scored from what the repository actually publishes — a security policy, a contribution guide, a release history, a code of conduct — read live from the provider rather than inferred from our own catalog pointers. This facet adds; nothing was taken away to make room for it. An open-source project is not excused from the commercial facets, because exemption would strip it of the points it does earn. If we have the wrong repository, or this product is not open source, say so on your provider repo and we will drop the facet rather than have you publish against it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 90 points between them, because the conditional facet above carries the other 10. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 90% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/cartesi: open an issue to ask a question, or submit a pull request to add artifacts.
