Arbitrum, an Ethereum Layer-2 (L2) scaling solution, announced that its mainnet would be available to users in August. The tool, which allows Ethereum users to transact with very low fees, was released in beta form last June, with support from some key Ethereum projects, including Uniswap, which received a community vote to integrate it. Arbitrum One, which will have up-to-date information about the projects using its network, will also be launched as part of the project.
Arbitrum is set to launch in August.
Arbitrum, the Ethereum L2 rollup, has announced that it will enter mainnet beta this month, allowing regular users to issue projects using the scaling solution. Arbitrum had previously been operating in a sort of sandbox, with over 250 projects applying to build using the Optimistic rollup tech. Arbitrum aims to massify adoption by allowing users to transact almost instantly with negligible fees.
Offchain Labs, the company behind the Arbitrum project, claims that determining the launch of its rollup was extremely difficult due to the need to coordinate the launch and deployment with several projects, including stablecoin companies. It was stated:
Many factors had to be considered when deciding when to launch. Over the last few months, we’ve been hard at work coordinating deployments with hundreds of projects and bringing many of the most popular stablecoins and tokens onto Arbitrum.
However, it will not be released at full capacity just yet. Offchain Labs stated that, while the network will be open to all users, they will impose “initial limits on the volume of activity,” with the intention of raising these limits as their solution matures.
Rollups that are optimistic
Arbitrum is technically a rollup, a type of second layer expansion structure that, while operating outside of Ethereum’s L1 network, posts information to it as proof of these operations. Arbitrum was one of the first commercial rollup solutions to use an optimistic approach. This means that the network assumes all operations are always honest and does not perform any computation to prove it. When a potentially fraudulent operation is carried out, there are safeguards in place to punish the issuer.
Arbitrum was recently chosen by Reddit to host its community points system. However, it is not the only upbeat rollup solution in the works. Another similar L2 rollup, Optimism, is currently in testing. Uniswap has also launched an integration with Optimism, which allows users to transfer funds via a gateway on its website.
Polygon, a scaling solution, is also a competitor to Arbitrum (MATIC). While Polygon is primarily a sidechain solution, Arbitrum and Optimism both make use of Optimistic rollups.
