Cartesi – Bringing Linux to Blockchain


Cartesi is a layer-2 blockchain platform that enables complex computations to be performed off-chain and integrated with blockchain smart contracts. The key innovation of Cartesi is bringing the power of Linux and mainstream software development tools to blockchain applications. Cartesi uses a hybrid on-chain and off-chain architecture to achieve scalability and computational power needed for complex computations. It has an optimized consensus algorithm based on Proof-of-Stake that incentivizes the network participants called Validators to verify the integrity of computations.

What Does Cartesi Do?

The main purpose of Cartesi is to overcome the limitations of scalability, storage and computation that exist on layer-1 blockchain platforms like Ethereum. It allows decentralized applications (DApps) to be built with programming languages and tools that developers are already familiar with, such as Python, C and C++. Cartesi provides an off-chain computing environment that runs Linux and can perform intensive computations or store large amounts of data at a fraction of the cost compared to on-chain execution.

The Cartesi architecture has two main components – the Descartes SDK and Noether node infrastructure. The Descartes SDK enables developers to interface with the platform using common programming tools. The Noether nodes connect the off-chain computations to public blockchains and handle the verification of results. Together, they make it much cheaper and easier to develop complex blockchain DApps.

CTSI Token

The native token of the Cartesi platform is CTSI which is based on the ERC-20 standard. The CTSI token is mainly used for staking by the validators on the Cartesi platform to participate in the consensus process and verify computations. CTSI tokens are also used for paying transaction processing fees on the network.

Developers use CTSI tokens to deploy and run their DApps and Linux-based components on Cartesi. As adoption increases, the demand for CTSI tokens is expected to rise. The current circulating supply is over 500 million CTSI tokens.

How Does Cartesi Work?

Cartesi implements what they term as “Descartes Rollups” which are state machines that perform transactions off-chain while storing minimal data on-chain. These rollups can run Linux containers to execute computations and provide fraud proofs to the blockchain of the validity of their results.

Developers can deploy chunks of Linux-based Docker containers with their application logic as components on the Cartesi network. Validators then execute these components and submit compressed cryptography proofs of the results to Cartesi blockchain. The blockchain verifies them and finalizes the state transition.

Current Progress

Cartesi launched the first version of its platform in 2020 and has since expanded the computational capabilities and range of development tools it offers. Some of the DApps built on Cartesi include machine learning algorithms, predictive analytics tools, IoT data processing pipelines, gaming applications and more complex financial smart contracts.

In 2022, Cartesi introduced staking which allows CTSI holders to earn rewards for locking up their tokens. There are also plans to enable decentralized storage and web3 hosting solutions through IPFS integration. Cartesi raised over $60 million from investors and continues to build partnerships across the blockchain ecosystem.


By leveraging Linux and off-chain computing, Cartesi provides a flexible foundation for the next generation of scalable and capable decentralized applications. As more computational power moves to its network, the utility and value of the CTSI token should continue growing. Cartesi has the potential to become a core infrastructure provider as blockchain adoption increases globally.
