A quick primer on Orbit, an in-depth look at Arbitrum's L3 "orbital" blockchain

Jinjin Finance Blockchain June 22 Arbitrum development team Offchain Labs today released Arbitrum Orbit development tools, quick start guides, and tools on the Orbit DevNet chain, and will release testnet and mainnet guides in the future. This article will study in depth Arbitrum's L3 "orbit" blockchain Orbit Quick Start Guide helps developers and decision makers to more easily develop on the L3 blockchain Arbitrum Orbit and manage their own Arbitrum Rollup and AnyTrust chains.

**What is Arbitrum Orbit? **

The Arbitrum Orbit chain can be seen as a deployable, configurable fork of Arbitrum's L2 Nitro technology stack, tightly coupled with Arbitrum's L2 chain, and you can also think of the Orbit chain as a tailor-made blockchain that can be customized according to Precise customization for specific use cases and business needs. Arguably, Arbitrum Orbit provides another way to gradually decentralize your application and gradually adopt the properties and security assumptions of the Ethereum base layer, while continuously integrating support for the Arbitrum Nitro stack (for nodes supporting Arbitrum's L2 and Orbit chains). Supported code), each Orbit chain can be configured to use Rollup or AnyTrust.

**What problem does Arbitrum Orbit solve? **

The Ethereum ecosystem is supported by a decentralized network of nodes, each running Ethereum's Layer 1 (L1) client software. Ethereum's block space is in high demand, so users are often stuck waiting for the network to become less congested (and thus lower costs). Arbitrum’s Rollup and AnyTrust protocols address this challenge by offloading some of the heavy lifting from the Ethereum network to another network of decentralized nodes supporting the Arbitrum One and Arbitrum Nova L2 chains, respectively.

Arbitrum The Orbit blockchain enables users to create their own AnyTrust and Rollup chains using their own infrastructure, so you can think of the Orbit blockchain as a self-governing priority channel on Ethereum, each Orbit blockchain is able to support Ethereum Many times the capacity of Ethereum, while directly benefiting from the security of Ethereum, simply put:

1. Arbitrum One and Arbitrum Nova unlock two public, DAO-managed contract deployment options that scale Ethereum and meet the needs of most projects.

2. Arbitrum Orbit unlocks an infinite garden of self-managed contract deployment options that can further expand Ethereum, and each individual Orbit blockchain can be precisely customized according to the needs of its owner.

**How does Arbitrum Orbit build dApps? **

If the dApp requires high performance or consistent resource availability, then dedicated throughput may be required, running the dApp on its own Orbit blockchain can significantly increase resource availability, so there is no need to compete for compute and storage resources. The Orbit blockchain will benefit from the same EVM+ compatibility introduced by Stylus, meaning you will be able to deploy EVM-compatible smart contracts using Solidity, C, C++, and Rust without migrating the languages and toolchains you already use.

If you want to separate your application blockchain's roadmap from Ethereum and/or Arbitrum's roadmap, Orbit can do that too, allowing cutting-edge features like account abstraction ahead of projects following Ethereum's public roadmap . Many types of dApps rely on predictable transaction costs, and because Orbit is isolated from Arbitrum L2 and Ethereum L1 traffic, using Orbit means it is not significantly affected by other applications' on-chain activity, allowing dApp users to Enjoy more reliable Gas prices, and Orbit also supports the use of other tokens as fee tokens, which in turn facilitates seamless integration with the dApp ecosystem.

**Is Arbitrum Orbit the same as "Application Chain"? **

Depending on the definition of "application chain", Orbit can be used as a specific application chain, but it is not only suitable for applications, because Arbitrum Orbit can also be used to use self-managed infrastructure and host EVM-compatible Smart contracts, while isolating computing and storage resources from Arbitrum's public L2 blockchain, and specifically selecting an L2 chain based on individual needs, which means you can use Orbit to:

1. Host smart contracts that support dApps, dApp ecosystems, or no dApps at all.

2. Host any EVM contract for private, centralized services.

3. Build a dApp that uses multiple Orbit chains to support redundancy, high availability, and trustlessness.

Summarize

Arbitrum Orbit allows developers to create their own dedicated chain, which is applicable to all Arbitrum second-tier chains, including: Arbitrum One, Arbitrum Nova or Arbitrum Goerli, and you can customize the privacy, permissions, fee tokens, and governance of the Arbitrum Orbit chain etc., and then unlock more potential use cases, such as launching a decentralized blockchain network powered by Nitro that supports stable Gas prices and self-pricing fee tokens.

Obviously, Arbitrum Orbit can help Ethereum move towards a multi-chain future, let us wait and see.
