Seeing the big picture from the small: The richness and value of the Arbitrum chain ecosystem When most people mention Arbitrum, they might still have the impression of the early Ethereum L2—a cheap and fast DeFi battleground. But if you casually open the Arbitrum Orbit chain ecosystem page today, you will find that it is no longer just a simple Rollup, but a multi-chain universe. Friends, the Orbit chain you often hear about is a customized independent blockchain built using Arbitrum technology. These chains maintain compatibility with the Arbitrum ecosystem while also possessing unique features. As of now, Arbitrum has supported over 100 chains, spanning multiple verticals such as DeFi, RWA, AI, gaming, NFT, and DePIN. These chains inherit the security and technical advantages of Arbitrum while achieving extreme customization, forming an unprecedented richness. An inspiration from an Orbit chain: @XAI_GAMES Among the many Orbit chains, if I had to choose the most representative case, I would pick @XAI_GAMES. Xai is an Orbit chain designed specifically for Web3 gaming, and it has not settled for a generic L2 framework but has made extensive customizations based on its own needs. Xai has achieved the following key features: 1. Exclusive gas token, freeing itself from ETH, lowering the entry barrier for players. 2. Local off-chain data indexing, optimizing the experience of frequent small interactions within the game. 3. Efficient transfer of game assets, with effective bridging to the mainnet and other chains. These details indicate that Orbit is not simply "copying an Arbitrum" but truly provides projects with a high degree of freedom: from virtual machine selection, fee models, privacy layers to data indexing, everything is fully customizable. Why do Orbit chains have more prospects than traditional public chains? The model of Orbit reminds me of the early internet era's debate between "dedicated servers" vs. "shared servers." Traditional public chains (shared servers): Everyone competes for a resource pool, with many restrictions and performance bottlenecks. Orbit chains (dedicated servers): Tailored infrastructure for each project. In scenarios like DeFi, RWA, AI, and gaming that require high concurrency, low fees, and even compliance, Orbit chains have a clear natural advantage. This combination of "modular + customizable" is almost closer to real application needs than any single public chain. Rather than saying Arbitrum is a chain, it is more accurate to say it is a framework for "blockchain infrastructure as a service." What this framework reflects is a profound understanding of the future of Ethereum L2: not all projects need a generic L2; some projects need a dedicated L2, and Orbit is the answer. In the future, if you see a popular Web3 game, AI platform, or RWA application, pay attention to whether it is running on an Orbit chain behind the scenes. This might be the greatest aspect of Arbitrum—seeing the big picture from the small, allowing every application to have its own chain while being closely connected within the same ecosystem.
