What is ARB ? - Arbitrum Explained
Arbitrum (ARB) is a layer 2 scaling solution for Ethereum, developed by Offchain Labs. It aims to increase the speed and efficiency of transactions on the Ethereum network by providing a platform for developers to build decentralized applications (dApps) with reduced gas fees and faster transaction confirmation times.
Arbitrum uses a technique called Optimistic Rollups, which enables it to bundle multiple transactions into a single batch and verify them off-chain, before posting a single result to the Ethereum network. This reduces the number of transactions that need to be processed on-chain, leading to faster transaction speeds and lower gas fees.
ARB is the native token of the Arbitrum network and is used to pay for transaction fees, as well as to incentivize validators who secure the network. Additionally, users who stake their ARB tokens can earn rewards for participating in network governance and decision-making.
Overall, Arbitrum aims to improve the scalability and usability of the Ethereum network, making it more accessible to users and developers alike.
Arbitrum uses a technique called Optimistic Rollups to achieve its goal of scaling the Ethereum network. Here's how it works:
First, a smart contract is created on the Ethereum network, which acts as a bridge between the Ethereum network and the Arbitrum network.
When a user wants to perform a transaction on the Arbitrum network, they send their transaction to the smart contract on the Ethereum network.
The smart contract then creates a "rollup" of all the transactions it has received, which is essentially a batch of transactions bundled together into a single transaction.
