From the current practical path, Cartesi is undoubtedly one of the first projects to transform its abstract architecture into an available execution foundation.
Since 2023, the technological evolution of blockchain underlying architecture has begun to enter a subtle and profound turning point. After Ethereum founder Vitalik Buterin recently expressed his preference for RISC-V, this open-source instruction set architecture quickly became the focus of discussion in the Web3 technology community. Vitalik proposed that RISC-V is expected to become the successor of EVM, reshaping the execution logic of Ethereum and even the entire crypto ecosystem, which caused significant shock in the industry and was seen as a positive response to the bottlenecks of existing virtual machine systems.
In fact, there is a concept in the technology world called the "Narrow Waist Law", which means that a sufficiently concise, universal, and standardized intermediate layer protocol or system architecture often becomes the connecting hub between upper-layer applications and lower-layer hardware. Just as TCP/IP became the "narrow waist" of the internet protocol stack, and Linux became the main platform of the modern operating system ecosystem, RISC-V is gradually approaching the core area of the blockchain "universal execution layer" in a similar posture.
Compared to highly customized and ecologically isolated execution environments like EVM, WASM, or MoveVM, RISC-V has natural advantages such as being open-source, concise, modular, and having a mature toolchain. It not only supports booting mainstream operating systems (such as Linux) but can also seamlessly interface with traditional languages like C/C++, Rust, and can significantly improve the security and development experience of smart contracts when combined with formally verified kernels like seL4. Once such a "technology as inertia" system is formed, it will produce an irreversible network effect.
However, compared to theoretical discussions, the actual landing progress of RISC-V in Web3 is still in its early stages. Although projects including Polkadot (PolkaVM), Nervos (CKB-VM) have incorporated it into their new-generation virtual machine systems, there are few projects that have built a complete, verifiable execution chain. This is also the long-term direction that Cartesi has been deeply cultivating, especially before Vitalik's high-profile support, Cartesi had quietly completed the full connection from the RISC-V architecture's bottom layer to the developer experience layer.
Five Projects Enter RISC-V, but Cartesi's Technology Stack is the Most Complete
The openness and flexibility of RISC-V are attracting increasing attention from blockchain projects. In the past year, multiple projects including Polkadot, Nervos, Wanxiang Blockchain, Web3 Pi, and Cartesi have introduced RISC-V into their virtual machine systems or underlying architectures. Their attempts not only verified the feasibility of this architecture in the Web3 context but also jointly promoted the early diffusion of RISC-V in on-chain execution.

Through the Cartesi Rollups framework, it has been integrated with mainstream Layer 2 networks such as Ethereum, Arbitrum, and Base, not replacing EVM, but expanding a stronger computational coprocessing unit on the EVM system. Complex computations and high-load logic can be completed off-chain, with the main chain only responsible for input/output and verification confirmation. This "off-chain operation + on-chain trustable" model provides a new engineering solution for Web3 applications.
In the current technological context, Cartesi is not eager to propose a "replacement" but has substantially built a universal, accessible, and developer-usable "trusted off-chain operating system". This is a path that few projects have truly navigated - not relying on rewriting the ecosystem or being constrained by compatibility, but instead completely introducing mature traditional computing systems into the off-chain computing framework while ensuring its on-chain verifiability. Its essence is to provide Web3 with a pluggable and reusable Linux layer.
Cartesi: A "Runnable" RISC-V Computational Network
When discussing virtual machine architectures, it's easy to fall into comparing abstract designs and theoretical advantages. However, for the blockchain industry, truly valuable standards are often simpler and more direct, and we only need to consider whether it can actually run. Cartesi provides a clear answer on this point. It not only built the Cartesi Machine based on RISC-V but also, through Cartesi Rollups, connected a high-performance off-chain computing engine with mainstream blockchain networks, forming a complete execution and verification closed loop with real landing capabilities.
Cartesi Rollups: Giving Off-chain Execution a "Trusted Pathway"
Cartesi Rollups is not a new Layer 2 network, but a modular framework supporting embedding Cartesi Machine into any Ethereum-compatible chain as an off-chain execution layer. Developers can use the Rollups architecture to build applications using traditional development languages, complete high-complexity logic processing in a Linux environment off-chain, and safely submit computational results back to the main chain through state proof and fraud verification systems.
The new mechanism breaks through the natural performance and complexity limitations of on-chain smart contracts. An example is that processing high-overhead tasks like image recognition, game logic, AI inference, and mathematical calculations on Ethereum often would be abandoned due to cost and performance bottlenecks. In the Cartesi system, these logics can be completely executed off-chain, with the main chain only bearing input/output and result confirmation, thereby significantly improving usability and development freedom.
