What Is Arbitrum

Key Takeaways:

  • ARB is the native ERC-20 governance token for the Arbitrum blockchain, which is designed to enhance scaling solutions for Ethereum.
  • Holders of ARB tokens can transfer value, vote on governance decisions, and participate in the Arbitrum ecosystem.
  • The initial supply of ARB tokens is 10 billion, with a maximum yearly inflation rate of 2%.
  • The ARB token is used for governance decisions, including the allocation of funds and technical changes.
  • ARB token holders can also vote on electing members for the Security Council, a team responsible for Arbitrum’s treasury wallet.

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 Arbitrum Works

Arbitrum offers a suite of L2 scaling technologies, including optimistic rollups, which allows Ethereum smart contracts to scale by exchanging messages with other smart contracts on the Ethereum mainchain and those on the Arbitrum second layer.

This technology is ‘optimistic’ because any validator can post a rollup block and confirm the validity of other blocks. Meanwhile, ‘rollup’ describes how public information can be used to reconstruct a complete history of the chain from an optimised log of events.

Arbitrum Rollup refers to the optimistic rollup protocol, and Arbitrum One is the first rollup chain in Arbitrum.

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.
