ARB

Overview of ARB

Arbitrum is a layer-2 scaling solution for Ethereum developed by Offchain Labs. It improves the functionality of Ethereum by increasing transaction speed and reducing gas fees without sacrificing the security and decentralization aspects of the main Ethereum network.

Arbitrum operates by taking transactions off the Ethereum mainnet and processing them on its own network, essentially lightening the load on the main Ethereum network. Arbitrum 'rollup' arms the Ethereum blockchain with efficient computational proofs to increase the number of transactions per second.

Arbitrum is suitable for a broad range of decentralized applications (dApps), from simple games to complex DeFi protocols, and allows them to run at a significantly increased speed and lower cost while retaining the same level of security provided by Ethereum.

Pros and Cons

What Makes ARB Unique？

Arbitrum's uniqueness lies in its approach to scaling the Ethereum network. Unlike other Layer-2 solutions, Arbitrum uses an optimistic rollup technology which allows it to handle smart contracts without requiring any modifications. This means that any existing Ethereum applications can be migrated to Arbitrum without making any code changes, which is a huge advantage for developers.

Additionally, by batching transactions together and rolling them up in a single proof on the Ethereum mainnet, Arbitrum is able to significantly reduce gas fees and increase transaction speeds while maintaining the security architecture of Ethereum Layer-1.

How Does ARB Work？

Arbitrum works as a Layer-2 solution for the Ethereum blockchain, improving its scalability and speed by processing most transactions “off-chain” and then sending a summary of those transactions to the Ethereum mainnet as single batches. This method is called a rollup.

Here's a more detailed process:

Off-Chain Execution: Users send transactions to the off-chain Arbitrum network where they are batch-processed. These transactions can include operating smart contracts, token swaps or any other operation that can be done in Ethereum Layer-1.

Rollups: These off-chain transactions are then 'rolled up' into a single proof that is submitted to the Ethereum mainnet.

Dispute Resolution: Arbitrum employs 'optimistic' rollups. This means they assume off-chain transactions are honest and accurate, but they provide a disputing period where anyone can challenge and counter-prove the accuracy of the rollup within a specified time window.

Finalization on Ethereum: Once the disputing period ends and if no successful challenges were made, the rollup is finalized on the Ethereum mainnet.

Ultimately, by processing most transactions off-chain and having only a single proof submitted on-chain, Arbitrum helps Ethereum in handling more transactions per second and significantly reduces the associated gas fees while maintaining security and decentralization of the Ethereum network.

Exchanges to Buy ARB

You can acquire ARB on various centralized trading platforms such as Binance, Coinbase, KuCoin, Bybit, Kraken, and Bitfinex, among others. In addition, it's also tradeable on decentralized exchanges like Uniswap V3 (both on Ethereum and Arbitrum) and SushiSwap (Arbitrum).
