1. What is Arbitrum?

A layer-2 scaling solution for Ethereum, Arbitrum is devised to work on the scalability and reduce the high gas fees linked to the Ethereum network. It is operating as a sidechain which runs with Ethereum mainnet and offers faster and cheaper transactions.

• It is compatible with Ethereum’s smart contracts which makes the developers port their existing Ethereum applications to Arbitrum with very minimum modifications.
• It uses an “optimistic rollup” approach which makes sure that most transactions are processed off-chain and validated on-chain, thus reducing the load on the Ethereum mainnet.
• As the transactions are processed off-chain, there is much lower gas fees in comparison to Ethereum.
• It relies on Ethereum’s security for dispute resolution.
• It is compatible with Ethereum’s ecosystem.

1.1. Overview

In 2018, a team of researchers and engineers established Offchain Labs, laying the foundation for what would become Arbitrum. The primary objective was to tackle the scalability and high gas fee issues plaguing Ethereum. In 2019, Offchain Labs introduced the alpha version of Arbitrum, a proof-of-concept showcasing its advanced rollup technology. The most significant milestone came in 2021 with the launch of Arbitrum One, the mainnet version of Arbitrum. This marked a major step towards providing a layer-2 solution for the Ethereum ecosystem.

1.2. How Does it Work?

Let us consider Arbitrum as a super-fast and cost-effective express line for the Ethereum network. 

• When someone wants to work with Ethereum, like trading, he can send the transaction to Arbitrum instead of the main Ethereum line.
• Arbitrum processes the work off-chain, just like a secret shortcut, making things super quick without dealing with heavy traffic.
• Once a transaction is processed on Arbitrum’s express line , one gets a ticket faster. It is verified on Ethereum’s main line which is slower but secure.
• Arbitrum takes less fees for faster rides as its work is mostly off-chain.
• In case of disputes, Ethereum’s security guards (its decentralised network) step in to rectify everything. 

It makes using Ethereum faster and cheaper by using a very wise shortcut.

1.3. Deciphering Layer 2 Scaling

Layer 2 scaling is akin to adding an extra express highway alongside the main road to reduce traffic congestion. In the cryptocurrency world, it involves creating a secondary layer parallel to the primary blockchain, enabling faster and more cost-effective transaction processing. This secondary layer can manage numerous transactions without overburdening the primary blockchain, enhancing overall system efficiency.

1.4. The Arbitrum Airdrop

An Airdrop refers to the distribution of tokens to eligible users who actively engage with the Arbitrum Layer 2 scaling solution. Here’s how the Arbitrum Airdrop operates:

• To qualify, users must interact with the Arbitrum network, whether by using DApps or conducting transactions on Arbitrum Layer 2.
• The Airdrop team takes a “snapshot” of the Ethereum blockchain at a specific block height, recording the addresses and balances of users active on Arbitrum up to that point.
• After the snapshot, tokens are distributed to eligible addresses on a one-to-one basis.
• In some cases, users may need to claim their tokens through a website or transaction.
• Once received, these tokens can be used in various ways.

Arbitrum airdrops reward early adopters and promote blockchain technology usage, fostering the growth of the ecosystem. One of the highly anticipated airdrops in 2023 is $ARB, with specific criteria for “active” user qualification.

1.5. The ARB Token in Focus

ARB is the native ERC-20 compatible governance token for the Arbitrum network, serving various functions, including value transfer, investment, and governance voting. The initial supply of $ARB at launch was 10 billion, with a 2% annual inflation rate. In March 2023, approximately 12.75% of the total supply was distributed among eligible users and DAOs, resulting in a circulating supply of around 1.275 billion $ARB.

ARB tokens grant users a voice in Arbitrum DAO governance. The DAO plays a pivotal role in decision-making regarding fund allocation, protocol operations, and system investments. These decisions are made transparently on platforms like Snapshot.org, where users can cast their votes. ARB token holders also participate in the election of members for the security council, a 12-member team responsible for managing the treasury wallet.

2. What is the Arbitrum Bridge?

It is a mechanism which allows a user to move his assets between Ethereum blockchain (Layer 1) and Arbitrum Layer 2 network. It is like a bridge connecting two stations, Ethereum mainnet and Arbitrum Layer 2.

• To use it, first deposit the assets, Ether (ETH) or other tokens, into a smart contract on Ethereum mainnet. 
• After depositing the assets, initiate a transfer through Arbitrum bridge by sending a request or transaction from Ethereum to Arbitrum.
• Once a request is received, it processes it on the Arbitrum layer 2 network. The assets become available on Arbitrum, where they can be used for faster and cheaper transactions.
• The assets can be moved back to Ethereum mainnet by initiating a withdrawal from Arbitrum bridge. The bridge would release the assets on Ethereum, and they become available on Ethereum again.

3. Key Benefits of Arbitrum

Arbitrum offers several advantages, making it a compelling choice for Ethereum users and developers:

1. Transaction Acceleration: Arbitrum significantly accelerates transaction processing, supporting a high number of transactions per second. This enhanced speed results in quicker and more efficient interactions with DApps.
