Arbitrum Orbit, a Layer 2 network for Ethereum, was announced on Friday (27th) after months of development. Blockchain developers can utilize Arbitrum’s technology to build their own Layer 2 or Layer 3 networks. Arbitrum stated that Orbit chain can adopt any improvements made to the Arbitrum Nitro technology stack without permission, bypassing the need for DAO approval. This includes features such as permissionless validation, MEV capture, and further cost reduction.
According to Offchain Labs, the development team behind Arbitrum, developers can create their own dedicated chains and connect to one of Arbitrum’s Layer 2 or Layer 3 chains on Arbitrum One, Arbitrum Nova, Arbitrum Goerli, and Arbitrum Sepolia. Projects like Syndr have previously revealed that they chose Arbitrum’s Orbit chain as the foundation and operated on Arbitrum’s Goerli testnet.
Arbitrum Orbit, which was launched earlier this year, was previously only operational on Arbitrum’s testnet. Steven Goldfeder, CEO of Offchain Labs, stated that this update allows these new Layer 3 networks to operate outside the testnet environment.
Additionally, the Arbitrum Foundation announced on Wednesday that it has selected modular solution Celestia as the data availability layer for Orbit. Once the solution is implemented, applications built on Orbit will have the option to publish their data to Celestia.
In recent months, there have been various customizable blockchain technology stacks in the market, and Orbit is one of them. OP Mainnet (formerly Optimism), a competitor of Arbitrum, has its own customizable environment called OP Stack, which currently supports Coinbase’s Layer 2 network Base.
