What is Cartesi (CTSI)?

Token price:

The Blockchain OS is a decentralised Layer-2 infrastructure that supports Linux and mainstream software components. It allows developers to build decentralised logic with Linux and standard programming environments preserving the decentralisation and security of blockchains. That means moving beyond Solidity and coding smart contracts with rich software tools, libraries, and services developers are used to. All while, free from scalability limits.

The Blockchain OS was founded to bridge the best of two worlds: intense computational jobs and independence of central authorities or middle men, as seen in the decentralised world of tomorrow.

CTSI Use Cases


At Travala.com, we offer more than 3,000,000 travel products in over 230 countries available for purchase with CTSI. Plus, you’ll receive a 2% giveback in the AVA rewards token on every accommodation booking.

Travala.com's intuitive booking experience is designed to be familiar and simple to navigate. Simply choose your desired travel product, enter your details, and select from a variety of available payment options, including traditional credit and debit cards, CTSI, and 90+ other cryptocurrencies.


Cartesi applications will be able to read and do complex calculations involving data from multiple sources. This will help interoperability between blockchains and services such as future and insurance markets.


Cartesi will unleash vast new possibilities for blockchain games. Developers will be able to use traditional tools and libraries that can be compiled for Linux. Additionally, game state processing will be free from the computational limits and high fees of blockchains without the need to sacrifice decentralisation.


Outsourced computation will allow for millions of users to lend their idle computing power. This will benefit scientific research, 3D rendering, video transcoding and many other computationally intensive tasks in a trustless way, without reputation systems.

Does Cartesi Have Low Fees?

Cartesi can be used to circumvent high Gas fees. With competitor fees at record-highs due to network congestion, Cartesi users enjoy low transaction costs as large portions of transactions can be conducted off-chain. The Linux Virtual Machine enables developers to take the most expensive computational requirements of their applications and shift them to a more affordable sidechain network. This data is then sent back to the blockchain to ensure full consensus is reached.
