1. What is Cartesi (CTSI)?

  • Cartesi - The Blockchain OS is a decentralized Layer-2 infrastructure that supports Linux and mainstream software components. For the first time, developers can code scalable smart contracts with rich software tools, libraries, and the services they're used to, bridging the gap between mainstream software and blockchain.

  • Cartesi is enabling millions of new startups and their developers to use The Blockchain OS and bring Linux applications on board. With a groundbreaking virtual machine, optimistic rollups, and side-chains, Cartesi paves the way for developers of all kinds, to build the next generation of blockchain apps.

2. Components of The Blockchain OS

  • Cartesi Machine: As a virtual machine, it was designed to bring mainstream scalability to DApps and mainstream productivity to DApp developers.

  • Cartesi Rollups: Allow smart contracts to run off-chain on Cartesi Machines. Since these support Linux, developers have the option to dispense with Solidity and the limitations of the EVM to create smart contracts with myriad mainstream software stacks, toolchains, standard libraries, file systems, and other OS resources.

  • Noether: A high-performance side chain for data availability which will act as The Blockchain OS’ storage and memory.

    • The Noether side chain is designed for temporary data availability, allowing DApps to achieve high throughput and storage of large files with reduced fees.
    • Noether's Proof of Stake system is currently live and running. Users can stake their CTSI and earn mine rewards to participate in Cartesi's growing network of validators.
    • Cartesi also has a design of a novel staking system that will later be implemented.

3. Existing DApps and Cartesi Labs

3.1 Cartesi Labs

Cartesi Labs is a program run by the Cartesi Foundation to fund research and to develop a decentralized system with our technology stack with The Blockchain OS. From the tech pioneer to the daring developer, Cartesi grants aim to foster the adoption of developers, grow the The Blockchain OS ecosystem, and support our community.

3.2 Cartesi’s Computational Oracle

Cartesi's computational oracle (previously called Descartes) is a decentralized computational oracle for Ethereum which will be migrated to become a feature of Cartesi Rollups.

Cartesi’s computational oracle executes massive computational tasks off-chain, on a Linux virtual machine fully specified by a smart contract. The results of the computations are fully verifiable and enforceable on-chain, preserving the strong security guarantees of the underlying blockchain.

3.3 Genesis apps on The Blockchain OS

Cartesi’s genesis DApps were built on top of early showcases of Cartesi’s technology or Cartesi’s computational oracle (previously known as Descartes).

  • Creepts: Creepts is a decentralized tower defense game built by Cartesi to showcase an early version of Cartesi's core technology.

  • Creol: An IoT commercial building control system that carbon offsets itself in realtime to be a carbon-neutral building control system. Creol is implementing Cartesi in their IoT devices to ensure that building stats measurements and computations are verifiable and securely inserted on Ethereum. Integrating Cartesi with their hardware is rendering their IoT system more resilient and fraud-proof.

  • SimThunder: Working to make sim racing more fun and realistic with NFTs and a marketplace, including private content sharing. SimThunder is using Cartesi as a way to ensure a marketplace for NFTs while maintaining privacy for items that have been shared. With the Descartes SDK, the SimThunder marketplace allows parties to securely trade NFTs and valuable contents.

  • Carti: An infrastructure project that aims to bring a packaging technology to life on Cartesi. The objective is to allow developers to have programmatic access to retrieve Cartesi Machines, leading to a better development experience.

  • Texas HODL’em: Texas HODL’em brings back safety to the online poker table. It is the first fully decentralized heads up poker game, built with mainstream cryptographic algorithms and software stacks.

4.4 CTSI token overview and use-cases

The token for The Blockchain OS has been designed to overcome the problems of scalability and inconvenience of blockchain applications. CTSI is the fuel of the network. When you use and stake CTSI, you collaborate with decentralization, security, and convenience for The Blockchain OS.

  • CTSI is a utility token that functions as a crypto-fuel for Noether:
    • Stakers receive CTSI rewards by staking their tokens and participating in the network.
    • Node runners are selected randomly according to a PoS system, and gain the right to create the next block.
    • Users of the network pay fees in CTSI tokens to insert data on the side-chain.
  • CTSI also plays a role with Descartes Rollups.
    • Validators will receive CTSI from applications and users when they provide their service for Cartesi Rollups applications.
