Arbitrum Stylus: Breaking through EVM limitations and introducing a large number of mature developers to the ecosystem

Original author | francesco

Compilation | Golem

Arbitrum’s upcoming Stylus upgrade will allow developers to program in other languages such as Rust, C, and C++ while being fully compatible with EVM languages such as Solidity.

This article will introduce the necessity of Stylus, its working principle and its significance to Arbitrum.

Why do you need Stylus?

EVM programming languages like Solidity have been the foundation (and initial development language) of the blockchain technology stack. However, this language also has limitations because it is relatively new compared to other mature programming languages and has a limited number of developers. It is estimated that there are about 20,000 developers using Solidity, compared to 3 million developers using Rust and 12 million developers using C++ (as of August 2023).

Currently, if developers want to develop on the blockchain using languages other than Solidity, they must do so on non-EVM blockchains, which may not have the same basic applications or ecological activities as the EVM blockchains. Therefore, blockchains must respond to developers’ demands for more programming languages and adapt accordingly, providing them with more flexibility.

These are the core reasons for the Arbitrum Stylus upgrade, which is expected to be launched in the coming weeks.

Beyond the Limits of the EVM

Stylus is defined as Arbitrums next generation programming language. Once Stylus is live, developers can write code in any language they like, taking advantage of the efficiency of Rust, C, or C++ while being fully compatible with the EVM. Stylus is expected to be available on all Arbitrum chains, including the Orbit chain.

With this upgrade, all Arbitrum chains will support MultiVM, bringing the following benefits:

• 10 times more efficient computing;

• 100x cheaper memory but 100x more efficient;

• Reduced transaction costs;

• Implement operations that cannot be done in EVM language.

In short, users can experience new applications and scenarios on Arbitrum and save more costs.

Stylus is a fully interoperable environment where developers can write code in Rust and interact with Solidity contracts as usual, while supporting the addition of various other languages. The comparison between Stylus and EVM is shown in the figure below:

Stylus has two virtual machines:

• Ethereum Virtual Machine (EVM): used for Solidity;

• WASM virtual machine (using WebAssembly): for Rust, C, C++.

The two virtual machines are not independent but work together. The contract in one virtual machine can call the other virtual machine and perform state transitions together. The fraud proof mechanism introduced from Arbitrum Nitro makes the implementation of the WASM virtual machine in Stylus possible. This mechanism allows the protocol to deterministically prove any WASM operation.

Opening the next wave of dApp building with Arbitrum

In addition to providing advantages to users through lower transaction fees, Stylus is also an upgrade for developers. By lowering the barrier for developers to enter the Web3 industry, Stylus makes it easier for developers to build applications on Arbitrum using the programming languages they are familiar with, which helps attract the next wave of developers to build applications on Arbitrum.

Stylus not only unlocks support for more programming languages on Arbitrum, but also provides better tools for developers. In addition, in the near future, Stylus will be able to support more programming languages, such as Go, Sway, Move, and Cairo.

Arbitrum founder Steven Goldberg previously posted on the X platform that Stylus is about to be launched. The first deployment of Stylus will also be supported by the Arbitrum Foundations Phase 3 funding program, which provides up to $150,000 in ARB funding for projects on the Stylus track.

Original author: Min Jung Original translation: TechFlow Summary Market makers contribute significantly to reducing volatility and transaction costs by providing significant liquidity, ensuring efficient trade execution, enhancing investor confidence, and making markets function more smoothly. Market makers use a variety of structures to provide liquidity, the most common being token lending protocols and retention models. In token lending protocols, market makers borrow tokens from projects to ensure market liquidity for a specific period (usually 1-2 years) and receive call options as compensation. On the other hand, the retention model involves market makers being compensated for maintaining liquidity over the long term, usually through monthly fees. As in traditional markets, clear rules and regulations for market maker activities play a vital role in the smooth functioning of the cryptocurrency market. The…
