Arbitrum vs. Optimism A new round of Red vs. Blue battle begins with Layer3.

Arbitrum vs. Optimism A new battle between Red and Blue starts with Layer3.

In the blockchain Rollup track, the competition between Arbitrum and Optimism is becoming increasingly intense. This article delves into the competitive landscape between the two, particularly how Arbitrum strategically combats Optimism’s market dominance by launching the L3 chain XAI based on its unique tech stack. The article also analyzes Arbitrum’s technical advantages, including its modular L3 stack Arbitrum Orbit, as well as its innovative verification mechanism BOLD and multi-language support SDK Stylus.

A fierce war has officially broken out in the Rollup field, with Arbitrum and Optimism being particularly noteworthy. Optimism is expanding horizontally with its unique OP Stack, while Arbitrum has chosen to undergo vertical transformation based on Arbitrum Orbit.

Arbitrum Declares War on Optimism

The Arbitrum team has launched the first L3 chain based on Arbitrum Orbit – @XAI_GAMES, formally throwing the spear of war at Optimism. The launch of XAI is strategically crucial for Arbitrum and can be seen as a clear challenge to Optimism (hereinafter referred to as OP). OP has leveraged its strong B-side resources to drive L2 chains built on its OP Stack, such as Binance and Coinbase, greatly expanding the ecosystem of L2. In comparison, Arbitrum appears relatively low-key.

OP Stack Ecosystem

Arbitrum Orbit

Before diving into XAI, it is necessary to understand Arbitrum Orbit. Arbitrum Orbit is a universal and modular L3 stack that allows developers to build dedicated L3 chains on top of it. The transactions on these L3 chains will be settled through Arbitrum’s L2 (such as Arbitrum One or Nova). XAI is built on Arbitrum Orbit and is specifically designed for gaming scenarios.

Arbitrum Nova vs. XAI

Nova itself is a general-purpose L2 designed for gaming scenarios, which should already meet the requirements of gaming scenarios. So why does Arbitrum need to launch XAI? The answer is simple: compared to a general-purpose gaming chain like Nova, XAI as a dedicated L3 chain can achieve higher performance and have dedicated computing and storage resources. This makes resource-intensive use cases (such as computationally intensive AI models) possible.

Technical Support: Nitro+ BOLD+ Stylus

Nitro

XAI will benefit from Arbitrum’s technical stack Nitro, BOLD, and Stylus. Nitro is an upgrade of Arbitrum One’s tech stack, which achieves higher Ethereum compatibility by directly compiling the core of Geth at the base layer of client software.

BOLD

BOLD is an permissionless verification mechanism proposed by the Arbitrum team, aiming to minimize the delay in settlement status. This mechanism solves the problem of the one-week challenge period in optimistic rollups, making withdrawals from L2 to L1 faster.

Stylus

Stylus is an open-source SDK developed by Arbitrum that supports the building of applications in multiple languages. Developers can use traditional Solidity language as well as WASM-compatible languages such as Rust, C, and C++ on Arbitrum, thereby reducing gas costs.

Modularity and Flexibility

BOLD and Stylus are also general-purpose modular components. Developers can natively integrate BOLD and Stylus when launching L3 for specific use cases based on Arbitrum Orbit. Alternatively, after L3 operates smoothly, these modules can be integrated through decentralized DAO governance by voting.

Conclusion

XAI has fired the first shot, opening the war between Arbitrum and Optimism. This confrontation may have just begun, but it undoubtedly marks the official start of a fascinating competition in the rollup field.
