What is Arbitrum (ARB)?

Arbitrum (ARB) is a layer 2 scaling solution for the Ethereum blockchain, designed to enhance speed and reduce transaction costs. Founded by Offchain Labs in 2018, it was created by Steven Goldfeder, Harry Kalodner, and Ed Felten. The name "Arbitrum" originates from the word "arbitrate", reflecting its role in efficiently processing transactions. Key facts include its focus on optimistic rollups to improve Ethereum's scalability and usability.

How does Arbitrum work?

Arbitrum is built on top of the Ethereum blockchain, utilizing a technology called optimistic rollups. This method allows it to process transactions off-chain while maintaining the security guarantees of the Ethereum network.
The functioning of Arbitrum involves several key steps:

- Transaction Batching: Transactions are grouped together and processed off-chain in batches, significantly reducing the load on the Ethereum mainnet.
- Optimistic Rollups: These rollups assume transactions are valid by default, which enables faster processing. If a dispute arises, a challenge mechanism allows for on-chain verification.
- Arbitrum Virtual Machine (AVM): This custom-built environment executes smart contracts with improved efficiency and lower costs compared to the Ethereum Virtual Machine (EVM).
- Security: The system relies on Ethereum’s security model. If any fraudulent activity is detected during the challenge period, it can be corrected on-chain, ensuring robust security.

Arbitrum enhances Ethereum's scalability by offloading most computational work off-chain, while only using the Ethereum mainnet for finalizing transactions and resolving disputes. This approach results in faster and cheaper transactions while preserving Ethereum's decentralization and security.

What are the benefits of Arbitrum?

Arbitrum offers several benefits compared to its direct competitors, such as Optimism and zkSync. These benefits include:

- Cost Efficiency: By processing transactions off-chain and batching them, Arbitrum significantly reduces gas fees compared to transacting directly on the Ethereum mainnet.
- Scalability: Arbitrum enhances Ethereum's transaction throughput, allowing for more transactions per second and alleviating network congestion.
- Security: Built on Ethereum, Arbitrum inherits its robust security features. The optimistic rollup mechanism ensures that fraudulent transactions can be challenged and rectified on-chain.
- Developer Friendly: Arbitrum is compatible with Ethereum’s existing developer tools and smart contracts, making it easy for developers to migrate their applications without extensive modifications.
- Decentralization: Arbitrum maintains decentralization by leveraging Ethereum’s underlying security and consensus mechanisms.
- Interoperability: The platform supports cross-chain interactions, enhancing its utility in the broader blockchain ecosystem.

Compared to Optimism, which also uses optimistic rollups, Arbitrum offers better EVM compatibility and lower fees. Against zkSync, which uses zk-rollups for even greater security and efficiency, Arbitrum stands out for its simpler implementation and broader adoption.

What is Arbitrum used for?

Arbitrum is primarily used to enhance the scalability and efficiency of the Ethereum blockchain by providing faster and cheaper transactions. Common use cases include:

- Decentralized Finance (DeFi): Platforms like Uniswap and Sushiswap utilize Arbitrum to offer faster and more cost-effective trading.
- Gaming: Blockchain games leverage Arbitrum for smoother and more responsive gameplay experiences.
-NFT Marketplaces: NFT platforms use Arbitrum to reduce the cost of minting and trading digital assets.

One specific case is the Arbitrum integration with Uniswap, a leading decentralized exchange. By using Arbitrum, Uniswap enables users to trade tokens with significantly lower gas fees and faster transaction times compared to the Ethereum mainnet. This integration enhances the user experience by reducing costs and increasing transaction speed, making DeFi more accessible to a broader audience. This is particularly beneficial during periods of high network congestion, where Ethereum gas fees can become prohibitively expensive.

What is DIA's Arbitrum API?

DIA’s ARB API is a real-time price feed for crypto assets, providing comprehensive and accurate data sourced from billions of individual trades across over 85 on-chain and off-chain cryptocurrency exchanges. These APIs deliver data that other web3 data providers cannot match.

API Explanation: An API (Application Programming Interface) allows different software applications to communicate with each other, enabling users to access specific data and functionality from a service.

Free API Endpoints: DIA offers free API endpoints for developers to test. These standardised endpoints are available for informational purposes and are easily accessible on the asset's detail page in the DIA App.

Custom API Feeds: The most significant benefit lies in DIA’s ability to create custom API price feeds tailored to specific needs. Users can request custom configurations regarding sources, methodologies, and update mechanisms. To obtain a custom feed, users can contact DIA via Discord or Telegram.

Use Cases: DIA’s APIs can be used in various blockchain applications, such as DeFi (derivatives, lending markets, stablecoins).

What is DIA's Arbitrum price oracle?

DIA’s ARB Price Oracle is a smart contract that provides real-time price feeds for crypto assets. Integrated with over 35 layer 1 and layer 2 networks, DIA can deploy price oracles across numerous blockchains. These price feeds are built from raw data collected from billions of individual trades on more than 85 on-chain and off-chain cryptocurrency exchanges, delivering a level of accuracy and coverage unmatched by other web3 data providers.

Blockchain Oracle Explanation: A blockchain oracle is an external information provider that supplies verified data from outside the blockchain to smart contracts, enabling them to interact with real-world data.

Free Demo Oracles: DIA offers free demo oracles for developers to test, accessible in DIA's documentation. However, these demo oracles are only for testing and cannot be integrated into production applications.

Custom Price Oracles: The real value lies in DIA’s ability to create custom price feed oracles tailored to specific user needs. Custom oracles can be configured in terms of data sources, methodologies, and update mechanisms. To request a custom feed, users can contact DIA via Discord or Telegram.

Use Cases: DIA’s price oracles can be utilized in various DeFi applications (derivatives, lending markets, stablecoins).

Why use DIA's ARB API & price oracle?

Both DIA's ARB API and ARB Price Oracle offer significant benefits for users in the blockchain ecosystem by providing accurate and reliable price data for cryptocurrencies.

The primary advantage of using DIA's API or Price Oracle is the high level of customization available. Each oracle and API endpoint can be tailored to the specific needs of decentralized applications. This includes configuration settings such as the data sources, data cleaning filters, pricing methodologies, and update mechanisms. This ensures that the data and oracle remain robust and resilient to market conditions, providing both global market prices and specific individual or cross-chain market prices.

Another major benefit is the transparency offered by DIA’s API and Oracle feeds. DIA provides full and granular transparency across the entire data journey, enhancing trust and reliability. Additionally, DIA offers various tracking and monitoring tools to closely track its oracle and API feeds, ensuring users have constant visibility and control over their data sources.

By leveraging DIA’s technology, users gain access to a tailored solution that meets their specific requirements, ensuring robustness, resilience, and transparency in price data.
