Ethereum scaling solution Arbitrum Orbit is officially mainnet ready, developer Offchain Labs says.<\/p>\n
This means that builders can create their own chains which will settle onto one of Arbitrum\u2019s layer-2 chains, including Arbitrum One, Arbitrum Nova, and testnets Arbitrum Goerli or Arbitrum Sepolia.<\/p>\n
Arbitrum is one of Ethereum\u2019s largest scaling solutions with an estimated 470 deployed apps onto its network and a total value locked (TVL) of $2.73 billion, according to information on DeFiLlama<\/a>.<\/p>\n Orbit enables developers to use the Arbitrum<\/a> code base to build customized chains, Steven Goldfeder, co-founder and CEO of Offchain Labs, told Blockworks in an interview.<\/p>\n Developers will have full access to the Arbitrum Nitro stack and will have the capability to configure privacy, permissions and fees on their Arbitrum Orbit chains.\u00a0<\/p>\n They can also customize their stack and plug into different data providers, while maintaining access to Arbitrum\u2019s other tooling, such as Stylus<\/a> and BoLD.<\/p>\n Read more:<\/strong> Offchain Labs makes BoLD moves with new permissionless validation protocol<\/a><\/p>\n \u201cWhereas the public Arbitrum chains are DAO governed and updates to those chains need to go through a DAO vote, you can take an Arbitrum Orbit chain which you govern yourself and actually front-run the DAO with these features,\u201d Goldfeder said. \u201cSo if you want to launch an Arbitrum Orbit chain with BoLD, you can.\u201d<\/p>\n Goldfeder explains that when speaking about \u201csettling,\u201d he is referring to what the chain is underneath.\u00a0<\/p>\n Ethereum<\/a> layer-2 networks like Arbitrum settle onto Ethereum, so chains that settle onto Arbitrum One or Arbitrum Nova would be considered a layer-3.\u00a0<\/p>\n \u201cIf you want to build a chain that settles onto an Arbitrum chain, in other words, a [layer-3] chain, that\u2019s open, permissionless, you don\u2019t need a specific license because that license is granted,\u201d he said.\u00a0<\/p>\n There are some projects, however, that may want to create their own layer-2 chain using the Arbitrum Orbit stack. In this case, Goldfelder explains that these teams can work with the Arbitrum Foundation to seek ecosystem alignment.\u00a0<\/p>\n \u201cYou will want to align with the DAO and the stakeholders because the DAO has the ability to grant these licenses,\u201d he said.<\/p>\n For the chains who do wish to settle onto Arbitrum, though, Goldfelder notes that the cost of onboarding users would go down drastically.<\/p>\n Any chain that wishes to settle on Ethereum will have to pay an overhead cost, Goldfelder explains.\u00a0<\/p>\n \u201cThe way to think about this is, if you go directly to Ethereum, it\u2019s like taking a car, but if you go through Arbitrum, your data is still going through Ethereum, but you\u2019re on the Arbitrum bus with all the other layer-3s,\u201d he said. \u201cSo you\u2019re going to share that overhead rather than paying for it yourself.\u201d<\/p>\n Goldfeder also notes that blocks on Arbitrum are elastic, meaning that if there are 100 transactions in a second, there would be four blocks created each second, but if there\u2019s an hour when there are zero transactions, there will be zero blocks created.<\/p>\n \u201cThere is not a fixed block time, which means that the cost of bootstrapping a chain on the Arbitrum ecosystem is low because you won\u2019t need to pay for empty blocks,\u201d he said.<\/p>\n Don\u2019t miss the next big story \u2013 join our\u00a0free daily newsletter<\/a>.<\/strong><\/p>\nTo settle to an layer-1 or an layer-2, that is the question<\/h2>\n
