A Layer-2 Optimistic Rollups Solution Bringing Mainstream Software to Smart Contracts.April 13th 2020 (updated on March 17th 2021)
Share this article
  • Cartesi is a layer-2 infrastructure for blockchains that allows developers to code highly scalable smart contracts with mainstream software stacks on a Linux VM. Cartesi uses a combination of rollups and side-chains.
  • Mainstream programmability: Developers can create smart contracts and dApps using the mainstream software stack that they are already familiar with. By moving most of the complex logic of their dApps to portable off-chain components, Cartesi empowers developers to select the best run-time environment in which to host each part of their dApps.
  • Scalability: Cartesi enables million-fold computational scalability, data availability of large files and low transaction costs. All while preserving the strong security guarantees of the underlying blockchain.
  • Privacy guarantees: Cartesi allows for decentralized games where players conceal their data and Enterprise applications that run on sensitive data, preserving privacy on dApps.
  • Portability: Cartesi is blockchain-agnostic and will run on top of most chains. The current implementations are supporting Ethereum, Binance Smart Chain, Matic (Polygon), with Elrond coming soon.

1. What is Cartesi (CTSI)?

  • Cartesi is solving the urgent problem of scalability and high fees on blockchains by implementing a variant of optimistic roll-ups. Most notably, Cartesi is revolutionizing smart contract programming by allowing developers to code with mainstream software stacks. Noether is Cartesi's side-chain that is optimized for ephemeral data, providing low-cost data availability to dApps.

  • Cartesi's competitive edge as a layer-2 and optimistic rollups solution is that it allows developers to code their smart contracts and dApps directly with mainstream software components and Linux OS resources. With mainstream programmability, dApp developers have a new expressive power to create more complex and featureful smart contracts. It also opens the doors for the adoption of regular developers who have never programmed for blockchain, and enables them to create decentralized applications with familiar software stacks.

Recent news

  • March 2021: Launched Noether v1.1
  • Feb 2021: Integration with Avalanche and Elrond to expand Layer 2 infrastructure within DeFi.
  • Jan 2021: Coinone and MyCointainer announces supporting for CTSI Reserve Mining and Custodial Staking.
  • Dec 2020: CTSI Reserve mining goes live.

Creepts

2.2 Descartes

  • Descartes is a decentralized computational oracle for Ethereum. Descartes 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 by honest Descartes node runners, preserving the strong security guarantees of Ethereum.

Descartes is currently live and implemented in several projects:

  • Creol Environments: 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: is working to make sim racing more fun and realistic with NFTs and a marketplace. 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.

2.3 Descartes Rollups

Descartes Rollups

  • Descartes Rollups is the implementation of Cartesi Rollups, enabling scalable smart contracts built with mainstream software stacks. Descartes Rollups is a variant of optimistic rollups with interactive dispute resolution.
  • Developers will be able to use countless mainstream software components to code smart contracts that run on a Linux VM. With Descartes, developers solves the scalability limits of Ethereum with million-fold computational gains, while preserving the strong security guarantees of the blockchain.

2.4 Noether

Noether

  • Noether is a high-performance side chain for data availability. It is Cartesi's side chain 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.
  • Noether is currently being bootstrapped through CTSI Reserve Mining. The staking rewards from the CTSI Reserve Mining are funded from the “mine reserve”, which avoids inflation in order to bootstrap the network. Early adopters who run nodes may earn higher staking rewards.

5.3 Commercial partnerships and business development progress

Recent and significant partnerships include:

  • Avalanche: Cartesi is integrating its layer-2 infrastructure with Avalanche (AVAX), enabling a Linux environment for smart contracts and higher computational scalability. Upon completion, developers building on Avalanche can implement contracts using mainstream software stacks supported by Linux. Software developers will be able to build smart contracts with uncountable software components supported by Linux.

  • Binance Smart Chain: Cartesi partnered with Binance Smart Chain (BSC) to allow advanced smart contract capabilities and massive computation for dApps atop the Binance Smart Chain. Binance Smart Chain is a highly scalable blockchain that supports smart contracts and Ethereum Virtual Machine (EVM) programmability, featuring high TPS (transactions per second), and fast decentralized trading with low fees.

  • Elrond: Cartesi partnered with Elrond Network to integrate optimistic rollups for high computational scalability and enabling a Linux runtime for smart contracts. Cartesi will expand the array of possibilities for smart contract developers building on Elrond, who will be able to use mainstream software stacks supported by Linux. Besides the advantages of higher productivity given by the vast software ecosystem of the world’s prevailing OS, smart contracts on Elrond will be complemented by massive off-chain computational throughput.

  • Polygon (Previously Matic Network) : Cartesi partnered with Polygon to enable greater responsiveness, faster transaction processing and lower transaction fees for dApps created on Cartesi. As part of Cartesi’s ongoing plan to have Cartesi dApps provide a seamless user and developer experience, Cartesi was also pleased to announce that their Creepts dApp was successfully tested on Polygon’s testnet. Polygon will also be exploring using Cartesi for their Plasma exits.
