Arbitrum Launches Mainnet for 10 Layer-3 Projects via Orbit Toolkit

Overview
Orbit is a developer support program that enables the creation of custom layer-3 solutions on Arbitrum, one of the largest layer-2 networks today.

Key Points
- Orbit Program: Launched earlier this year, Orbit allows developers to create their own layer-2 or layer-3 networks on top of Arbitrum. Previously, these networks were only deployed on Arbitrum's testnet.
First 10 Layer-3 Projects: The initial 10 layer-3 solutions utilizing Orbit include XAI, Cometh, Syndr, Polychain Monsters, Meliora, Sanko GameCorp, OurSong, Deri Protocol, Hook Protocol, and Superposition.
After months of development, Arbitrum Orbit is mainnet-ready! 🪐

Significance of Orbit
Orbit is a crucial step in the decentralization of the Arbitrum network. In June 2023, Offchain Labs released documentation for Orbit on the devnet. According to the managing entity, Orbit will enable developers to create layer-2 solutions easily on the Arbitrum network, including Arbitrum One, Arbitrum Nova, Arbitrum Goerli, and Arbitrum Sepolia.
Comparison with Competitors
Arbitrum is not alone in developing solutions that allow projects to build networks using their technology. For instance:
- Optimism (OP Labs): Provides the OP Stack.
- Polygon: Offers the CDK layer-2 development solution.
- Matter Labs (zkSync): Provides ZK Stack with a "Hyperchain" vision.
Latest Developments
On October 26, Arbitrum integrated Celestia into Orbit, creating a parallel data layer alongside the existing solutions on Arbitrum One and Nova.
Conclusion
The launch of the mainnet for these layer-3 projects marks a significant milestone for Arbitrum's ecosystem, promoting further decentralization and innovation within the blockchain space.
