What Is Crypto Arbitrum (ARB)?

Arbitrum is a Layer 2 scaling solution for the Ethereum blockchain that powers fast smart contract transactions while reducing transaction costs.

Layer 2 solutions can scale the base Layer 1 blockchain by delegating complex computational tasks, such as transaction processing and data storage to the second chain. In short, the Layer 2 blockchain executes the smart contract, and the Layer 1 blockchain stores the data.

In the context of Ethereum, Arbitrum handles blockchain transaction processing and batching, reducing congestion and cost from the main network.

For instance, DeFi projects like Sushiswap and Aave use Arbitrum in the hood to offer efficient swaps with lower gas fees.

What Is the Arbitrum Protocol?

Arbitrum is the brainchild of Offchain Labs, a company founded by Ed Felten, Steven Goldfeder, and Harry Kalodner. It offers a Layer-2 (L2) scaling solution for Ethereum, designed to enhance the network’s capabilities by increasing transaction speed, helping to improve scalability, and adding privacy features.

Arbitrum’s primary goal is to address the limitations of Ethereum’s smart contracts, including inefficient performance and high execution costs, which have been factors negatively impacting the Ethereum user experience.

How Does Arbitrum Work?

Abritrum’s Layer 2 solution uses blockchain rollups to achieve efficient transaction processing. Rollups use a 2-layer architecture to process transactions off-chain before settling them on-chain. The benefit is that the blockchain no longer needs to validate separate transactions – it can directly confirm a “rolled up” batch of transactions.

This scaling solution differs from other Layer 2s, such as sidechains, since rollups typically derive their security from the main blockchain.

Arbitrum’s scaling solution uses a particular type of roll-up called optimistic rollups.

What Is the ARB Token?

ARB is an integral part of the Arbitrum ecosystem, serving as the governance token for the Arbitrum blockchain. It is an ERC-20 token designed to enable token holders to participate in the decision-making processes of the network and have a say in the development and direction of the ecosystem.

Features and Utility of the ARB Token

1. Transfer of Value

One of the primary functions of the ARB token is to facilitate the transfer of value within the Arbitrum ecosystem. Holders can send and receive ARB tokens securely and efficiently, making it a convenient means of exchange within the network.

2. Governance Voting

ARB token holders have the power to vote on important governance decisions that shape the future of the Arbitrum ecosystem. These decisions may include the allocation of funds, investments in the ecosystem, and technical changes to the network infrastructure.

To participate in the governance process, token holders submit their votes through an open forum like Snapshot.org, where they connect their wallets and cast their votes on an open proposal. The voting process is transparent and democratic, allowing token holders to express their opinions and contribute to the ecosystem’s development.

3. Security Council Election Decisions

In addition to governance decisions, ARB token holders may also vote on electing members for the Security Council, a 12-member team responsible for managing the treasury wallet of the Arbitrum ecosystem. By participating in these elections, token holders help to shape the composition of the council and ensure the security and integrity of the network.

Tokenomics of the ARB Token

Understanding the tokenomics of the ARB token is crucial for evaluating its potential value and utility within the Arbitrum ecosystem. Here are some key details about the tokenomics of the ARB token:

  • Initial Supply: The initial supply of the ARB token is set at 10 billion tokens.
  • Inflation Rate: The token has a maximum yearly inflation rate of 2%, ensuring a gradual increase in the token supply over time.
  • Distribution: The distribution of the ARB token is as follows:
  1. Investors receive 17.53%
  2. DAOs in the Arbitrum ecosystem: 1.13%
  3. Individual wallets: 11.62%
  4. DAO Treasury: 42.78%
  5. Team and future team plus advisors: 26.94%

It’s important to note that the allocation numbers mentioned above are subject to change based on the decisions of the Arbitrum DAO, the decentralised governance body responsible for the network.


Arbitrum has emerged as a highly promising layer-2 scaling solution for the Ethereum blockchain. It offers faster transaction speeds, lower fees, and enhanced scalability, addressing some of the limitations faced by Ethereum during periods of high activity. With its innovative approach, Arbitrum has gained significant traction, surpassing Ethereum’s transaction count and boasting a high Total Value Locked (TVL) of $1.68 billion. The platform’s growth is further supported by the active deployment of contracts and the increasing number of unique addresses on the network.

By leveraging the power of the ARB token and embracing decentralized governance, Arbitrum is empowering its community to contribute to the platform’s development and shape its future. As Ethereum continues to evolve, Arbitrum’s role in providing a more efficient and cost-effective solution for decentralized applications remains pivotal, solidifying its position as a leading player in the blockchain industry.
