Due to the increasing demand for expansion and cost optimization, Layer 2 solutions are rapidly developing. Numerous new projects with new technologies are being launched to address existing issues. Some notable names in this field in recent times include Optimism, Metis, and StarkWare. Additionally, another potential name is Arbitrum. Let us explore this project and Arbitrum Ecosystem notable features through the following article in a formal and informative tone.
What is Arbitrum?
Arbitrum Ecosystem is a set of open Layer 2 solutions designed to address congestion issues on the Ethereum network. Layer 2 refers to a technology or system that operates on Layer 1 and inherits its security properties, while also having the capability to process more transactions, reduce costs, and provide faster transaction confirmation times than Layer 1.
Arbitrum provides 3 scaling solutions: Rollup (OPU), Channels, Sidechains
- State Channels: It is required of the user to send a snapshot of the Ethereum status into a Multi-sign Contract. This snapshot carries significant data, such as the balance of the address. An off-chain system of this nature enables transactions to be executed free of charge with immediate completion and high-end privacy.
- Sidechains: The proprietary blockchains operate independently with their own separate consensus rules, allowing Ethereum transactions to be transferred under supervision to ease the burden on the primary Ethereum network.
- Rollups: Similar to advanced, non-custodial sidechains, rollups can significantly enhance the scalability of Ethereum’s main network. To date, there are four main types of rollups that have been developed, namely, Optimistic Rollups, zkRollups, Plasma, and Validium.
What is Arbitrum One, AnyTrust, Arbitrum Nova, Arbitrum Nitro?
Offchain Labs, the parent company of Arbitrum, offers a range of product offerings such as Arbitrum AnyTrust, Arbitrum Nova, Arbitrum Nitro, and Arbitrum One.
- Arbitrum One: Arbitrum One, alternatively known as Arbitrum, is a product that operates on the Optimistic Rollup technology and is specifically designed for the DeFi and NFT market.
- Arbitrum Nitro: Arbitrum Nitro is not a separate chain, but rather an upgrade implemented on Arbitrum One with the aim of providing better performance and lower fees for its users. Additionally, Nitro employs the use of WASM virtual machine and Geth programming language.
- AnyTrust: AnyTrust is a technology that is designed to optimize costs and speed, and its foundation is based on the assumption of “minimal trust.”
- Arbitrum Nova: The Arbitrum Nova chain has been established using Offchain Labs’ AnyTrust technology and is targeted towards the Social, Gaming, and other industries that require the processing of large volumes of transactions at low fees.
What is Optimistic Rollup?
Rollup is a Layer 2 scaling solution that enables the bundling or “rolling” of transactions on a sidechain into a single aggregate block that is then recorded on the Ethereum blockchain. This provides the ability for transaction data on Layer 2 to be easily accessible on Layer 1, as needed, in order to verify state transitions. It should be noted that Rollup is an open source platform that offers improved scalability and reduced gas fees for developers building decentralized applications on the Ethereum network.
Optimistic Rollup is a solution for scaling off-chain transactions on the Ethereum platform. Transactions are executed off-chain, while the data is compressed and stored on the base layer to achieve consensus and verify the integrity and availability of data on the base layer. This approach helps to reduce the load on the Ethereum blockchain, improve transaction speed, and enhance the overall efficiency of the system.
Considering all the scaling solutions for Ethereum. Arbitrum is classified as follows: Ethereum Scaling Solution => Off-chain Scaling Solution (Layer 2) => Rollup => Optimistic Rollup => Arbitrum.
Along with Arbitrum, Optimistic Rollup has other projects such as Optimism, Boba Network, Metis, Fuel,…
Arbitrum’s Distinctive Features
Distinctive Features of Arbitrum
Arbitrum offers an extended solution within the Rollup model. The key distinguishing factor of Arbitrum pertains to the operational aspect of Fraud Proofs. For instance, in the event that an individual proposes a Rollup block and another person believes it to be incorrect, how will Arbitrum address this discrepancy?
Arbitrum is set to utilize a multi-round rollup protocol to address disputes, wherein it will break down the disputes into smaller ones until they become increasingly insignificant and subsequently resolve them on-chain.
Advantages of Arbitrum
- The “multi-round rollup” approach adopted by Arbitrum enables a considerable reduction in costs associated with Fraud Proofs. The project aims to provide a low-cost solution that can be widely implemented while supporting highly complex transactions.
- Arbitrum is fully compatible with Ethereum’s virtual machine (EVM), providing a comparable experience to working with smart contracts on L1 and compatibility with ETH tools. Additionally, Arbitrum can execute EVM code directly, without requiring the smart contracts to be recompiled.
- The withdrawal time on Arbitrum is comparatively lower than that of other Rollup solutions like Optimism, which takes around 1-2 weeks. The project is presently exploring several other solutions to minimize the withdrawal time further.
Arbitrum ecosystem thrives
The Arbitrum Mainnet was launched in late May 2021, and since then, various projects and developers have been successful in developing their projects on Layer 2. As of March 2023, the Arbitrum ecosystem has become the fourth highest Total Value Locked (TVL) ecosystem in the market, with several notable projects currently running such as Uniswap, GMX, Sushiswap, Curve, and more.
Disadvantages of Arbitrum
The approach of utilizing “multi-round rollup” also leads to a prolonged dispute resolution process. In its ambition to support various other scaling solutions such as sidechains and channels, Arbitrum faces the challenge of navigating the complex transition between these solutions which is a matter of significant concern.
