In the continuous development of Blockchain technology today, the Ethereum network is facing the challenge of slow speed and high fees. ARB, as an innovative solution, has emerged, acting like a multi-level interchange bridge built for the congested digital highway of Ethereum.

ARB's core goal is to improve the performance of Ethereum, allowing users to enjoy faster speeds and lower costs when using Web3 applications. Currently, ARB mainly provides two main channels:

Arbitrum One is the backbone of ARB, mainly serving important decentralized finance (DeFi) applications, such as lending and trading platforms. This channel maximizes security and fully inherits the security features of Ethereum.

Arbitrum Nova is a dedicated fast lane, mainly targeting applications such as games and social media that require high transaction volume but are extremely cost-sensitive. It achieves ultra-low fees and faster transaction speeds by slightly lowering the trust level.

The core technology supporting these two channels is Arbitrum Nitro. This is the most basic technical layer of ARB, providing the operational foundation for all products. Based on Nitro, ARB mainly adopts two scaling methods:

Arbitrum Rollup: This is the technology used by Arbitrum One. It compresses multiple transactions into a package and deploys them to the ETH mainnet to fully leverage the security of the ETH network.

Arbitrum AnyTrust: This is the technology used by Nova, a variant of Rollup. It relies on an external small group to ensure data availability, although trust requirements are slightly lower, it can provide lower costs and faster withdrawal speeds.

Looking ahead, ARB also plans to launch the Orbit platform. This platform will open up the underlying technology of ARB, allowing developers to build their own small-scale networks based on the Arbitrum Nitro engine. These networks will ultimately connect to the main ARB network, forming a larger ecosystem.

Overall, as a scaling solution for Ethereum, ARB provides different technical channels for applications to choose from, opens up underlying technologies to further expand the ecosystem, and always pursues faster speeds and lower costs. This innovative solution is expected to greatly enhance the performance of the Ethereum network, bringing convenience to more users and developers.
