Focusing on the Rollup track, the competition between Arbitrum and Optimism is really fierce.Optimism expands its OP Stack as the flag level, while Arbitrum has created L3 innovation through Arbitrum Orbit vertically.
The Arbitrum team personally participated in the first L3 -XAI of Arbitrum Orbit, and officially declared war on Optimism.

In my opinion, the launch of XAI has an important strategic position for Arbitrum, which is a positive declaration of OP.OP uses powerful B -end resources to promote the construction of the L2 chain based on its OP Stack, such as the OP Stack, and expand the L2 ecological layout on a macro. At the time, Arbitrum seemed obedient and did not see much.As OP’s development is in full swing, the rapid launch of XAI is not a coincidence.

Arbitrum orbit
Before talking about XAI, I had to talk about Arbitrum Orbit.
Arbitrum Orbit is a general -purpose modular L3 stack, allowing developers to set up a dedicated L3 chain based on it. Transactions on L3 will settlement through the Arbitrum L2 (Arbitrum One or Nova).XAI is the L3 chain based on Arbitrum Orbit, focusing on game scenes.

Arbitrum nova vs. xai
Nova is a universal L2 focusing on the game scene. It is reasonable to meet the needs of the game scene. Why do you also launch XAI?The reason is simple: Compared to the positioning of the Nova game public chain, XAI as a special L3 for the game can achieve higher performance, and has dedicated computing and storage resources.
This makes it possible for resource -intensive use cases on the chain, such as calculating dense AI models.XAI will benefit from Arbitrum’s technology stack: Nitro+ Bold+ Stylus.
Nitro is an ONE technology stack upgrade.The core of Geth is directly compiled through the basic layer of the client software. Geth is the mainstream Ethereum client, so as to achieve higher Ethereum compatibility.The difference between Arbitrum Nitro/ONE/Nova has been spoken separately before, so I won’t go into details here.

Bold
BOLD is a delay of minimizing settlement state.For optimistic Rollup, there is a week of challenge, and users will wait a week from L2 to L1.
During the challenge period, the verification person can initiate a challenge if you find that there is a problem with the L2 transaction submitted.There are two questions here: 1 Who has the challenge authority?2 Why isn’t anyone challenging?
The current fraud prove that the challenge mechanism is not required to be permitted, they are all challengers by specific roles.If the challenge is not required, malicious challengers can not be confirmed by launching a DDOS attack.By introducing the BOLD mechanism, on the one hand, the verification does not require the required permission, and it is more in line with the concept of centralization of the blockchain;
On the other hand, the delay of minimizing settlement status.BOLD allows a single honest verification person to win in Ethereum with any number of opponents in Ethereum, thereby causing DDOS attacks to fail.
Stylus
Stylus is an open source SDK supporting multi -language construction application developed by Arbitrum.This is a product that realizes EVM+compatibility.In short, developers can use traditional Solidity languages on Arbitrum and use WASM compatible languages, such as Rust, C and C ++, etc. to build applications.
In addition, Stylus makes the execution of Dapps more efficient and significantly reduces GAS costs.Stylus is not limited to supporting Rust, C and C ++, such as Move, Sway, Cairo, and Go.Imagine that DAPPS on Aptos/Fuel/Starknet can migrate one click to Arbitrum.You can even implement a one -click L3 chain chain change through Arbitrum orbit.
>
What’s more interesting is that Bold and STYLUS are generally modular components; developers start L3 based on ARBITRUM orbit to start specific use cases, which can be natively integrated with BOLD and Stylus;After running, vote to decide to integrate the above -mentioned modular components.
XAI has launched the first shot of the ARBITRUM L2 defense war. This contest with Optimism may have just begun.above.
