Hello world.
There’s a new OS
We’ve taken 30 years of software development and given it a new home. To the makers and mavericks, the dreamers and the pioneers, we say welcome.

Hello,
Blockchain OS
Cartesi is the first Blockchain OS. It allows developers to build decentralized logic with Linux and standard programming environments preserving the decentralization 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.
Cartesi provides an over 10,000x increase to computational scalability for blockchain.
The Blockchain OS allows for much more sophisticated decentralized applications, which would otherwise be impossible on layer-1.
The Blockchain OS enables the use of mainstream languages and tools like, C++, Python, and SQLite.
Cartesi endows traditional applications with the same level of security guarantees achieved by the underlying blockchain.
Blockchain-agnostic and currently supporting all EVM chains: Ethereum, BNB Chain, Avalanche, Polygon, etc.
From games where players conceal their data to enterprise applications that run on sensitive data, The Blockchain OS preserves privacy on your applications.
Technological Comparison
Ethereum ¹ | Cartesi Rollups | |
---|---|---|
Runtime environment | EVM | Linux VM |
Languages | Solidity | All ² |
Development tools | Nascent / Immature toolchain | All ² |
Smart contact privacy | None (very expensive) | Possible (no extra cost) |
Computational Throughput | x | > 10,000x (no fees) |
Transaction Throughput | x | x; > 15x; > 40x ³ |
Fee costs per tx | x | x; > x/15; x/40; ³ ⁴ |
Security | L1 consensus | Similar to L1 consensus |
¹ As compared to Ethereum or other blockchain/baselayer used by Cartesi Rollups.
² Consider idiosyncrasies of RISC-V's ISA and the Cartesi Machine.
³ Respectively, for each phase: Cartesi Rollups; CR + Aggregator v1; CR + Aggregator v2.
⁴ Transaction cost only. Computation is for free.
