About Arbitrum (ARB)

Arbitrum Frequently Asked Questions (FAQ)

What is the primary function of the ARB token within the Arbitrum ecosystem?


The ARB token primarily functions as the governance token within the Arbitrum ecosystem, allowing holders to vote on key decisions and participate in managing the network's protocol.




How does Arbitrum benefit from the security and compatibility aspects of Ethereum?


Arbitrum benefits from the security of Ethereum by leveraging its decentralized network for securing users' funds and its dispute resolution mechanism. Transactions on Arbitrum are batched and periodically submitted to the Ethereum mainnet, ensuring the security of Arbitrum's Layer 2 relies on the robustness of Ethereum's base layer. Compatibility-wise, Arbitrum runs Ethereum Virtual Machine (EVM)-compatible smart contracts with minimal changes, allowing developers to easily deploy existing Ethereum dapps on Arbitrum and users to interact with these dapps using familiar tools.




What are the key features of Arbitrum's optimistic rollup technology?


The key features of Arbitrum's optimistic rollup technology include off-chain execution with on-chain data availability, reduced transaction fees, scalability by processing transactions in batches, fraud proofs to ensure security, compatibility with Ethereum smart contracts, and a one-week challenge period for potential dispute resolution.




How do ARB holders participate in the governance of the Arbitrum network?


ARB holders can participate in the governance of the Arbitrum network through a decentralized governance process, wherein they can propose changes, vote on proposals, and have a say in key decisions regarding the protocol's development and upgrades. The specific mechanisms and platforms for such participation vary and may involve community forums, governance portals, or directly through on-chain voting, contingent upon how the governance framework is structured within the Arbitrum ecosystem.




What is the role of the Security Council in the Arbitrum DAO?


The Security Council in the Arbitrum DAO acts as a safeguard mechanism, endowed with special powers to intervene rapidly in cases where the network's security is at risk. Its responsibilities include the ability to fast-track decisions related to upgrades or critical bug fixes to protect the integrity of the platform.




How will Orbit, Arbitrum's layer-three solution, enhance the network's capabilities?


Orbit, as Arbitrum's layer-three solution, will enhance the network by improving scalability and reducing costs. It will enable further increase in transaction throughput beyond what layer-two solutions provide, while retaining the security of the Ethereum mainnet. Orbit will allow for more complex and resource-intensive computations to occur off-chain, further relieving congestion on the core network and promoting efficiency in transaction processing.




What programming languages will be supported by Stylus for deploying on Arbitrum?


Stylus for deploying on Arbitrum will support Solidity, Vyper, and other EVM-compatible languages.




Who can become a validator on the Arbitrum network, and how does the expansion affect network security?


Anyone with the necessary technical knowledge and resources to operate a node can become a validator on the Arbitrum network. The expansion of validators enhances network security through increased decentralization and redundancy, making it harder for any single entity to compromise the integrity of the system.




Are ARB tokens required to pay for gas fees on Arbitrum?


No, ARB tokens are not required to pay for gas fees on Arbitrum. Gas fees on Arbitrum are paid in ETH.




In what way does Arbitrum promise scalability and how does it plan to handle thousands of transactions per second?


Arbitrum promises scalability by using a layer 2 scaling solution called rollups, which process transactions off the main Ethereum chain, providing faster and cheaper transactions. It plans to handle thousands of transactions per second by bundling multiple transactions together off-chain, generating a cryptographic proof known as a rollup, and then submitting this proof to Ethereum. This means fewer data needs to be stored on the Ethereum blockchain, reducing congestion and increasing throughput.




What makes the Arbitrum ecosystem appealing to developers and users compared to other Ethereum L2 solutions?


The Arbitrum ecosystem stands out due to its unique rollup technology, which offers low transaction fees and fast finality while maintaining a high level of security through its connection to the Ethereum mainnet. Its optimistic rollup approach allows for broad smart contract compatibility without major modifications, enabling an easier transition for developers and a rich DeFi ecosystem. Additionally, Arbitrum's decentralized, permissionless network, with its upgradable features and community-driven governance, creates a developer-friendly environment that emphasizes seamless user experience and cost-effective deployment of dApps.




How is the Arbitrum secured and what mechanism is in place for dispute resolution in case of fraudulent transactions?


Arbitrum is secured using the security of the underlying Ethereum blockchain. It relies on a system of validators that monitor and validate all transactions on the Arbitrum layer. If a validator suspects a fraudulent transaction, they can initiate a dispute resolution process. This process involves asserting the correct state of the virtual machine and providing evidence to challenge the fraudulent transaction. The dispute will then be settled on the Ethereum mainnet, ensuring that the true state of the chain is maintained and that any fraudulent activity is correctly handled and rolled back if necessary.
